Required items

Silvertop 20v quads, complete if you can..
Silvertop 20v TPS (hopefully you get it with the quads)
Manifold adaptor eg – tecnotoytuning
3mm vac hose (2m max)
5mm vac hose (2m max)
3mm t pieces/elbows
5mm t pieces/elbows
5-6mm barb fittings
inlet manifold gasket
JDM AE86 throttle cable?
Acess to a drill press
Tap/die set
Small bit of sheet ally (to make a throttle cable bracket)
Hacksaw/file (to cut/shape the ally)
Steel cable, cable clamp from a bike shop (for accel cable)


1. remove fuel rail/manifold/tvis (if fitted) etc from the head
2. the manifold adaptor you have.. I'm going to use the T3 one for an example, the billet CNC machined adaptor, is a stunning manifold, I almost didn't want to put it on it looks soo good! use a drill press tap 4 holes in the bottom of the manifold, 1 in each runner, infront/behind the 3mm ones.. NOT beside.. you might not be able to get to the studs if you put them beside them.. then tap thread into the ally for the barbs you have chosen, nice and easy in ally.. this is to link together with the 5mm vac hose to act as a balance tube (much smoother idle) and as a very strong vac for the brake booster. [attachment=3362:attachment]
3. The T3 one comes with 4 3mm fittings in each runner, as they are all separate I ran 3mm vac hose with elbows/t pieces linking them all up, and facing the firewall.. I used this to run the Map sensor as pic above
4. make a small right angle bracket with 2 holes that bolt into 2 of the throttle bodies.. I just cut a U shape and used the throttle cablenuts to tighten either side of it.. you'll see the 2 holes I'm talking about.. there only small!
5. bolt the throttles to the manifold.. make sure all the vac hose is hooked up.. use zip ties as hose clamps [attachment=3363:attachment]
6. bolt the complete manifold on the head with the new gasket
7. I used my JDM throttle cable, having a 4AGE in there you should have a similar length cable.. I just pulled it through under the pedal to the correct length as it was about 6 inches too long and used a grubscrew cable clamp from a bike shop as the new end on the pedal.. just leave the bit of cable hanging around there.. I did.. ha ha
8. that's about it.. fine tune the length of the cable on the car..
9. bolt on your injectors and rail to the head.. connect up the fuel lines..
10. plug in your booster line and map line
11. i had to rewire my TPS in reverse so it would read properly like so

tps side > loom side
brown > yellow
Blue > red
Red > Blue
Yellow > brown


12. start her up.. see how she idles.. the individual idle screws I didn't really touch.. nor the butterfly adjusment ones.. I just use throttle cable tension for idle speed..as long as you checked that they opened evenly on the bench.. adjust so they all move at the same time etc..

[attachment=3364:attachment]

the stock 4AGE ecu will run them ok.. but it will run on the rich side.. i didn't test an SAFC, eventually i just went straight to a aftermarket ecu using only TPS..

what they sound like (http://images.cainer.net//uploads/project_revs.wmv)

Matty

this has worked for me, and i am happy to answer any questions etc

yeah i was wondering that too.

what trumpets/filters are you running? if any?

Sounds sweeeeet, can't wait till mine are on!

also... what is the part no for the gasket between the manifold and the head? or does this come with the manifold when you buy it from T3?

will it be ok to run an safc with a stock ecu? and still be not too rich?

the gasket between the quads and the manifold, was the stock 20v ones.. there little metal ones.. thats why i mentioned try and get a set, sorry forgot to mention why http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

the inlet manifold gasket is just a smallport AE92 inlet manifold gasket.. $8 from repco, or comes in a VRS kit...

the i made some trumpets and an air box, but i am now redesigning it in favour of silter socks http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

there are people on club4ag that have done similar to what matt did and used an SAFC. it helps with the general tune but youll never get it perfect. things like throttle pump you cant change. plus you wont have control of the timing. and thats how you make real power with an NA 4ag.

if you pick up an safc cheaply its a worthy addition to the conversion, but ultimately you really want aftermarket managment when you can afford it.

what did you do with the water outlets that normally go into the original throttle body. did you just join them up with a peice of hose?

15th May 2006, 10:25 PM

15th May 2006, 10:33 PM
because there is still some settings on the computer that run off of a vacuum. well there is on my mircotech anyway, such as deacceleration fuel cutoff.

mattysshop
16th May 2006, 08:46 AM
i don't... it's blocked off now.. but i needed it originally to use the stock ecu (map sensor)


the water outlets in the trottle body i have never ever ever used.. i piss that shit off on every motor i have put in here.. causes more problems than it's worth.. so yes.. blocked off..

also the cold start injector... don't need it.. not even with the stock ecu.. i just blocked it off with some white thread tape and a bolt in the fuel rail.. also with the stock ecu i wasn't running an o2 sensor, or yellow plug sensor in the original inletmanifold, fu@ks me what it was for.. but it obviously didn't need it http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

yellow plug sensor is air temp. i would run it just zip tie it under the throttles somewhere.

matt is describing how he set his car up with quads on stock managment BEFORE he went to aftermarket. on stock managment you definately have to hook up the map sensor. try disconecting yours on your stock motor and see how it runs.

they car probably would have run so much better if you took the intake temp sender out of hte original manifold and put it between or around the throttles, would have run less rich, thats why it was doing so, cause it couldnt get a reading, air temp and map is a must on a standard ecu. what do you think SAFC adjusts to make changes from http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

if you have bigger cams, and a bit of port work etc.. and want to run quads also..

an SAFC will not be enough..

the SAFC will only help on WOT.. not on idle/cruise/town driving where most of driving is done..

just save up a little more and go full aftermarket.. then you can get the full potential out of the motor..

i was struggling to keep up with a stock reco'd bigport when i had the stock ecu on my motor i built.. (JAE86) but after the ecu.. pulled car lengths on some 20v powered ones!!

Matty, are you sure your info is correct?

SAFC's can make two sets of fuel changes .. high load, and low load. You can set what throttle changes differ this (i.e. high load = 60% and above, low load = 20% and below), then the computer makes a curve between both loads.

I know that i have used a SAFC to road tune my girlfriends silvia, which has an RB20, HKS 2510, and unknown injectors.. While i didnt touch high load much (didnt want to risk leaning-out without a EGT and air/fuel probe), we mucked around with the low load settings enough that it became very driveable. To give you an example, you were almost choking at idle from how rich it was running, and even at highway cruising you could smell (and see) the rich smoke.

I don't mean to sound rude, i just don't think you have a proper understanding of an SAFC http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif. Plenty of kiwi kids have used quads, SAFC, and 270+ cams to very good results.

Yes, they can't adjust timing and whatnot, but they are great for the money (if you buy them second hand, 200-250$$)

No, you were saying that it wasn't possible/streetable to run quads without an SAFC, which is clearly wrong.

You just can't get the most power out of a sprinter (as you said) without being able to touch timing.

I just wanted to clear up that it IS possible to do so, on a budget. Again, if you are after the best gains, aftermarket management is the key.

WOT shouldn't need to be touched... just idle/cruise maps..

leave the idle a bit fat.. cos you can't run a cold start injector.. http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

Toko - i didn't delve too far into the SAFC... basically i just went for the complete solution first time, as the $$ wasn't really an issue..

I'm about to put quads on my redtop in an Austin Healey Sprite. ST quads on a T3 manifold. Also putting in some HKS 272 8.1 cams and doing some mild porting – mainly cleaning up. Already running a Motec M4. Clearance issues mean I might have to chop the TPS mount off the end TB and stick an aftermarket TPS on the other end of the quads. Not sure about trumpets/filters/airbox yet (clearance again). I'd like to get a cold air intake system – the engine bay is pretty tight and gets pretty hot.

If, on the off chance, anyone is running similar with a Motec...I'd love to get hold of a motec map to suit that I can use as a headstart on the tuning.

I'll put details up of how it goes once it's in.

I recently installed my AE111 quads onto my standard 85-87 96kw Bigport. First note. Adapters that have the quad's the right way up, not fun. So much interfearence with the fuel rail and tps on the water inlet so I had to use the Tvis plate, gutted and sealed to space it from the fuel rail, then luckly i used a FWD water inlet, lopped the sensor bit off and now it clears just.

I first set it up to run on the Standard ecu, does this fine. Runs a little rich on some cruising parameters, idles well and the idle isnt rich, at WOT its fuel mixture is spot on. Used an adjustable ecu and its not as good as it needs tuning and this ecu supplies little features. Sometimes likes to idle, other times doesnt.

I find that it has increased the engines capabilities some what, and has opened the top end up a huge ammount. all in all, its well worth the mooooooooneeeeey.

electric mic
2nd August 2007, 06:17 PM
So its a noticiable difference then? I was looking at this an alternative to 20v power initially. How much (ballpark) did it cost you to set up matt?

Matt-AE86
3rd August 2007, 03:23 AM
Throttles:
Well, I had a BT 20v sitting on stand, so I used the AE111 Throttles. You can find AE101 throttles for around 250 these days.

Adaptor plate:
I messaged a few people around about for an adaptor plate and found rare item from brad here on the forums, looked to be customer milled up possibly in japan. I got that for $250. Usually people sell there T3 ones for around $350 and I think to get one new ends up being $500~ from the states. Now from experience the T3 adaptor would work best. Mine keeps the throttles around the correct way BUT the TPS fowled on the Water intake at the front of the head and also the throttle linkage fowlled on the Fuel rail.

I used a gutted TVIS plate to push it forward and it cleared nicely and I also chopped the water temp gauge sensor of my water intake and had this filled. With the TVIS adaptor, It has actually cause some type of 'Smallport' reaction I would think also not matching my AE111 throttles to the manifold, It has possibly created 2 areas for turbulance and interfearence, which I think is another possibility for crap idle.

Note: I wanted to try and run the TVIS on the motor but I couldn't do it due to things interfearing, even with a 2nd TVIS as a spacer ie; working TVIS + spacer (gutted TVIS) + quad adpater.. Things got in the way, modification and grinding would have been needed, but It runs really quite well like this and is still good down low, suprisingly for a bigtop. (Also still running a 3.9 Final Gear!)

ECU:
I used the standard ecu at first. This runs good at WOT cruising at 1500-3000rpm it can start climbing to be rich. Idle for me is abit rough but varies and I think this has more to do with tuning the quads to having the same air intake etc. Note: BT throttles and I think possibly ST ones, have an Idle adjustment. probably best to turn these all back till they are tight and turn them up in equal lengths.

MAP:
At the moment I have the map sensor reading of Cyl. 2 & 3. I've done a bit of research into this and found a guy in japan that was playing around with it alot, have all cyls coming into 1 vacumm pot then off to sensor, then grouped, then 2 lines into pot than into sensor, then some all 4 grouped then straight to the sensor and some gave rough idle and he found a nice setup but still changed it around to meet conditions I think.

Also run your Air intake sensor. Unbolt this from your manifold, plug it in, and have it close near the throttles. Temps vary from 25-35degC. Run the rear water temp sensor aswell. Make sure your O2 sensor is connected etc.

TPS:
You will need to have a 100kw TPS plug as the 20v one only has 3 wires and 16v uses all 4. You then need to reverse the wiring as the 20v throttles run backwards. This plays a big role I found as well and keeping the engine running smooth and detects the throttle, assists the MAP sensor some what.

FPR (Fuel pressure reg) + Brake booster:
These both run of Cyl 4. Seems to be fine, braking feels a bit funny, but you can feel its just lost a tad bit of assistance.

So really your looking at around $600-$900 to run quads on a standard ecu. It also depends if you search for cheap buys or want to just go and buy it.

Then you have;

Velocity stacks.
I got some from a plate over east (I'm in WA) some 50mm ones which are roughly $120~ a set inc postage. I found some in Aust that are specific to AE101 or AE111 but they were $250 a set. I am yet to put these on but at the moment using some AE101 trumpets bolted on by 1 hole, these helped the engine run a bit smoother as well.

Filters:
These can vary in price and be purchased from same place you get your Velocity Stacks/Trumpets.

Any other questions you have, I will try my best to answer. I might put some diagrams up on how to run the MAP sensor etc and some video footage.

This was a good way to waste 30mins at work :D

So is your 4a-ge stock?? and are you still running stock ECU??

It's a Standard Kouki 96kw Motor (Bigport with 7Rib block, Standard) It seems to be in really good condition and still holds GREAT/AWESOME compression and yer I went back to using standard ecu cause it was better than my adjustable hahaha.. still runs good though :)

MATTY: How would a standard ecu better than a aftermarket one's??...So just 100% standaed ecu??..i mean like no other piggybacks?

An aftermarket ecu is always going to be better, just the one I was using didnt offer enough as it was a very budget ecu, but worked well for standard motor and turbo, I just didnt find it good to drive daily, once it was driving it was fine, but didnt want to idle and a few things, ignition was strange.

hey guys, i was just wondering if you could answer this question for me,

im about to buy an adapter to fit 20v itb's to my 16v bigport and i dont know which one i shoul get?

these are the two types available:

1. The first adaptor allows you to mount the entire 20V manifold to your 4age 16V motor allowing you to maintain the driveabilty originally intended by toyota.

2. The other adaptor requires you to remove the 20v ITBs and mount them to the adaptor and install a vacuum manifold. I would recommend the this adaptor for a FWD or turbo setup or if you need to run MAF instead of MAP thus requiring a plenum.

i dont know if i should go with the 1st or second one? i think matt(who made this topic) went the second one?
which one can i run with out a plenum and just have trumpets? because with the second one he says you need to install a vacum manifold?
because the 20v quad throttle system im buying comes with the 20v manifold but i dont know if i need to fit that?

thanks for your time.

The first one is good, as you said, It has all the correct vacuum lines and stuff to run specific things like idle up, and to tap into the rocker breather etc but I would think in an AE86 engine bay you would have some clearance issues on cyl. 4 with the trumpets/stacks.

The second one is ok, but requires a bit more of a customer setup, plumbing into it for various things is needed also, but gives more clearance

adsrx, can you post a link to each adapter you are looking at?

id use one that goes quads - head, as otherwise you are compromising, using the shape for the 20 valve head that you dont need.

Just a rough price comparison to the above.

ITBs ~$250
T3 adaptor ~$400
JNT Performance Trumpets ~$100
Home Made Flanges ~$50

Total $800 - All delivered. This is roughly what I've paid (except that I got the ITBs for free). Mine is on a bigport head, so the injectors are cast into it already, and the T3 adapter has hose attachements tapped into it so these will provide a pressure reading for the MAP sensor. Head and the rest are being machined, will have it back and complete by the end of next week.

Regards,
Chris

hey what do u mean by "Mine is on a bigport head, so the injectors are cast into it already"

roadsailing
20th November 2007, 03:26 PM
whats he means is all 16 valve 4AGEs have the injector holes in the heads, not the inlet manifold like the 20 valve.

those blue trumpet ones have the injectors in the quads, better for atomisation at hight revs, but i'd mount them upstream of the butterlys for that.

for those that have put these sexy quads on their 4ages... how much power gain are we REALLY talking about? is it really worthwhile doing in term of performance or is this more for cosmetics? cheers

there not worth doing if thats all your putting on the engine.
but
if you have some cams and a set of extractors to suit, with after market management, then you get good gains.

I got gains on a standard motor. But yer, obviously your going to get a lot more from Cams, Headers, Exhaust, Ecu in the full blow.

how much do u guys think i will gain, bigport bottom end (stock), smallport head, fully ported and polished, t3 manifold, ST quads, t3 trumpets (75mm), HKS valve springs, Wade 308 duration cams, t3 adjustable cam gears, adaptronic computer, n hopefully a fkn mad tune

i have most of that except 288 cams and an safc piggy back and im making 81rwkw.

a tunable ecu will give it a little more.

i wouldn't use a stock bottom end with 308 cams. your top power range would be around 9000rpm.
also youd want some half decent extractors.

DRFTR86
21st December 2007, 05:56 PM
yeh i realise that bottom end wont hold up revs so gonna probably limit it at 8000, and yeah HKS super header is what im probably gonna go with

Cerby
22nd December 2007, 08:19 PM
have you researched whether the 308 degree cams will interfere with the shims? Or have you got an under bucket shim setup?

why would u run cams with that kind of duration unless it was a pure animal track car which it clearly isnt....i think it would be more sense to run lower duration cams (272 or 288) and simply built the head for more lift...

+1

Also, by limiting the rpm to only 8000 to save the bottom end is a waste of the big cams as they need more revs to produce the power!

Delazy
22nd December 2007, 10:32 PM
so many ppl think duration creates more power.....durations put simply moves the "powerband"....bigger numbers arent always better......

learn to drive ur car within a bee's dick of its potential before u bother building a engine that ull prolly only ever drive to 70% of its capabilities

DRFTR86
24th December 2007, 03:31 PM
i understand that i will be limiting its power, head is being built by a head shop, all shims are being taken care of by them, i just bought all the parts and did the porting myself, its gonna be a dedicated track car and towed to all events, and when the bottom end gives way, then i will build a fkn tough bottom end, i know that the powerband will be very high in the rev range, but until i have a tough bottom end, i wont be using 100% of the power

chapl
24th December 2007, 04:15 PM
hmm sounds like a waste untill you build your bottom end.

at least get your stock bottom end balanced.

DRFTR86
24th December 2007, 06:12 PM
yeah that was planned, cant afford a mad bottom end atm as i still need to set up a good driveline n suspension package

mattysshop
28th December 2007, 09:00 AM
well it would suck then if that weak bottom end of your decided to let go at constant 8000rpm age and throw a piston or two into that head that you just spent all your money on...

i have a 7 rib bottom end sitting in my shed if your interested.. it would be great with a simple ring and bearings.. and good balance.. it would see 8500rpm all day no troubles.. balance is the key..

has anyone used a 16v tps on the 20v quads? i tried fitting one to mine the other day and it bolted up fine, the only problem i can see is that it may not rotate the same way as the normal throttle body, and it's slightly larger than the 20v one.

saves re-wiring the tps plug if it does work though
