mr2 aw11

[Rice86]

my fellow ae86 people, im helping out a mate whos starting to mod his mr2 aw11

first thing, WHEELS!! what 14', 15' offsets will sit right at the standard guards clearing the usual things you might hit

reason why we are looking for phat rims for the aw11 is that he is getting his fulls and wanting to turbo charge the thing :thumbup:

so second question...his got 4age 100kw in it i believe, what will be needed to turbo it...ECU, a turbo, turb mani, etc...

whats best engine option to go turbo?...buy shit to make the engine compatible with turbo?...i already advised him to get a gze with ecu and loom and drop the badass in with a turbo setup...oh and did those all come with same gearbox for the non SC model and SC?..

let me know what you people rekon, im trying to find a decent mr2 forum but finding a good one with peoples build thread is taking its toll =.='

thanks again

turbo option

go get a 4AGZE - from a aw11 if you can and do it that way otherwise you have to rebuild the 4AGE with forged internals where as the AGZE will have them stock.

toymods is a great site :)

hope this helps

Probably best asked on toymods.

The Supercharged one came with a stronger gearbox. The differences are similar with the AE92 GTZ coupe. The normal 4A-GE versions got a regular Corolla gearbox, C52 or similar. The 4A-GZE versions got the stronger E52, E58 or similar gearbox. The E series box has a 4 pinion diff, and a oil pump, and a little oil return loop visible outside the box. The Axles are different also.

It is said that the E series diff in some is LSD, but I can't confirm that yet.

4agze does not have forged internals standard.

[Rice86]

any thing else we should be thinking about?...

gearbox was really good info, thanks jonny

and will be turning to toymods if i come up with more technical questions

[sun_moon]

im an aw11 owner, but im makeing a 7age engine as it is very easy and cheap.

as for rims stock is pos38 ish. could go 16 by 7 with a positive 20ish offset with slight guard mods...

16s is the shit, fuck 15s

[kAmbo]

4agze have forged pistons. other then that its the exact same as the 4AGE version of its same era, eg smallport map gze is the same as a smallport 4age besides the pistons.

Rice86: go on toymods, might get something out of the AW11 Owners Anonymous thread.

as for rims, 15's seem to suit a small car like the aw11. 16's if your looking for a brake upgrade.
for 6.5wide rims, your looking at +32 offset

for 7wide rims, your looking at +36 offset.

yes it does , pistons are internals?


4agze does not have forged internals standard.

Does anyone here understand the different manufacturing process for casting or forging pistons (pictures of either process), the differeneces in strength of materials (using actual stress numbers), and how to determine how a pistons is made from witness marks?

[Vance]

casting is the pouring of molten metal into a cast.

grain structure is the same everywhere in the piston. this gives an equiax grain structure that that has no strong points. it will hold together but when put under enough pressure it will break.


forging is where metal is heated to a solidus state (highest temp possible before liquidisation) and then forced into shape.

when refering to pistons this is done by a mechanical press. this gives an elongated grain structure around the surface of the piston which holds together much better when under pressure.

[Clinton]

i remember reading a thread on the old dc? someone that actually tested the pistons. i cant rememeber how they were formed. but i remember they werent forged.

still definatly stronger than GE standard bottom end though. just not forged

Not forged. Hyperetectic.

That is all well and good. But can you look at a piston and know by the flash marks wether its forged or cast?

Also, is there any Toyota sourced info stating which pistons are forged or cast? (club4ag does not count).

[lo_rolla]

^it's pretty obvious really.

[Jonny Rochester]

How so?

[dr1ft-pig]

my advice is buy a rearcut from a supercharged MR2 (AW11 4AGZE)

use aftermarket ecu (adaptronic,microtech,motec etc) to get rid of the AFM as the mr2s use this standard then u can tune it to run as much boost as you see fit without making the ecu shit its pants and start crying

buy turbo and manifold

whack it in with the box from the rearcut as ive been told the s/c versions have the LSD box

thrash it


for wheels, from memory the aw11 have a 4x100 stud pattern, so thats a start
the one my cousin just bought has 4x100 to 4x114.3 spacers on it so if you want to do that then you must sacrifice in offset

thats about all i know

hope i helped

[kAmbo]

yep 4x100 pattern. bit of a pain as most 4x100 is fwd poo. nothing made really wide in the aussie land that is 14-15inch

[Rice86]

nice info guys, toymods is a bit gay no offence, hard to find the info im after, and also cant register hahah

but again, thanks, really is helping with the brain storming

[dr1ft-pig]

u can get superlites in 4x100 i think

15x8 -4

would need guard flarage but would look phat

[kAmbo]

yeah adsport have them on his car, in some crazy offset too.

[Nikkojoe]

I think he has sportmax not superlites

15x8 0offset :)

[kAmbo]

my bad im drunk

[awang]

not trying to hijack the thread, i've read the 4agze specs given by riojin, what is the meaning of the 'snap ring' for the piston spec of the 4agze ae101?

what does it mean by that 'snap ring'?

[sun_moon]

some good 16inch rims for FF cars can be used an aw11s.
i think 16s looks perfect (imho that is).
although to run 15s, just buy 4x114.3 rims in offsets that ae86 drivers consider shit, such as 14x6 pos 25 or something (example) and have the holes filled and redrilled... u could have some awesome offset for an aw11 and good width oldskool rims, for a cheap price. win.

Maybe talking about how the pin is held in the piston.

normal 4A's, like bigport are sweat / press fit. gze's etc are floating and the assembly is held in by small rings that sit in a groove in the tunnel which stops the pin sliding out.

[Hen may possibly be a nut]

I strongly concur with Kambo. ZE pistons are forged (see here (http://forums.toymods.org.au/index.php?t=msg&th=22256&rid=&S=748b8b0b01445a4c898f03fb90abfafb&pl_view=&start=0#msg_184686)). Otherwise there are no internal differences GE vs GZE. Also bear in mind that a AW11 halfcut will have the oldest type of ZE in it, still good, but there were some improvements made over the years, so in some ways an AE101 motor would be better, plus most likely fresher.

There is infinite amounts of info about AW11s on Toymods, maybe mr2oc and lots more. Make the effort to sign up and you'll find anything you want to know.

A forged pistons looks forged, where as a cast piston looks cast.

Not being a smart ass, but when I deal with them that's how I tell. Or what box they come in ahahaha.
