Copied,
i can see this question being asked more than once. here is a list of the parts required to do the conversion, if i have missed anything let me know and i'll update the post (its 10:26pm and i have been at work since 4, thats 4 this morning which means i got up a 3 to get to work )


AE86 or AE71 engine crossmember
AE71 gearbox x member (86 one can be used)
AE71 pedal box
AE71 or AE86 clutch master cylinder
AE71 or AE86 solid clutch line from master to slave, and rubber hose
AE71 or AE86 rubber engine mounts
AE71 or AE86 steel engine brackets
AE71 or AE86 gearbox stays (link box to block)
AE71 tailshaft if keeping the ke70 borg diff
AE86 tailshaft if using S series
AE86 tailshaft with T18 back half if using T series diff
T50 gear box
obviously a 4AGE of some sorts JDM being easier, ADM FWD being a little trickier but no big deal.

thats just what you need to get the engine in there, you will also need

modify tank pickup with fuel pump, plus mod top tank plate with a 8mm fitting for fuel feed.
fuel hose (injection spec)

loom to suit, either modded AE82 loom if using a bigport, modded AE92 loom if using a smallport, or a slightly less modified JDM loom again if you are using a bigport.

and what acc cable do you use if you have a ke70?

The stock one seems to be too long, or can you still use it?>

i used a ke70 cable as the ae71 is too short (same as 4ac ae86's)
its looped around the cmc

also u will need the ae71 t50 crossmember (not sure if u can use the k40/50 member?)

(AE86 on the top, ae71 bottom)

with the cmc, holes will need to be drilled into the firewall

for Auto conversions the shifter hole will need to be wider

ae71 4ac radiator, both rad in and outlet is on the same side for the 4ac, ke70 rad will need some extention

also since i used a fwd motor i used a electric thermo fan

also pics of said 4a rwd engine mounts and gbox stays

ryco Z200 universal efi fuel filter with a 4ac coil mount to look stocky

note: it has 8mm nipples
the stock ae71 lines fuel lines are 6mm and 4mm return

VL Fuel pump, mounted with 4ac coil mount used lol

would prefer intank fuel pump but this will do for now

if you can upgrade to ae86 struts and brakes
will need the whole ae86 struts (springs, shocks, brakes, etc...)
use the ke70 strut top and ae86 steering arm (get jdm if u want more lock lolz)

Wiring 4age
http://club4ag.com/faq_and_tech_pages/ECU%20Japan%20AE86%204A-GE.htm


Another thread on alternator wiring found here
http://www.ae86drivingclub.com.au/board/index.php?showtopic=29433

*Assuming bigport* When using my info, Refer to Club4AG AE86 ECU pinout/wiring diagram
Other then that:

-give ignition power to positive terminal on coil (usually a black/orange wire which connects to the ballast resistor on the old coil which you can use [I did], but you can make your own relay to power coil using the black/orange wire as an ignition trigger)

-On 14 pin plug, Pin 7 (+B1) and Pin 14 (+B ) can be connected together, and go to ignition (or can come off a relay you used for coil power)
-On 14 pin plug, Pin 6 (Batt) goes to constant battery 12V source (ie wire straight from positive terminal on your battery if you want)

For fail safe starting, you may also need to give power to injectors (Yellow wire found on 10Pin plug, Pin 10 (BF)) by joining a wire into the yellow wire and giving it 12V on iginition (again, use the same relay that you may have used for coil, but might be drawing too much current).

There ARE other ways to do it, and probably make it neater and more factory like but that works.

Fuel pump relay setup (if you dont have a factory COR relay).

I used an EP92 starlet cable, depending on the manifold though you may need to shorten the cable inner wire. The outer sheath is right on though.

Gearbox stays are not really needed, but if you have them, definatly use them.

I used an Odyssey Linear Slick BMX brake cable as my throttle cable, works well.

Quick question, Looking at gettin an AE71, 4AGE's bolt directly in correct?

slydar

yeah. the engine will mount using the stock mounts and transmission. 20v will need the dizzy moved or the firewall clearenced.

you should really use a surge tank or get a jdm fuel tank or you will get fuel surge when the tank is low going around roundabout/thrashing etc.

for this you require a small low pressure lift pump to fill the surge tank then a main EFI pump (VL etc) to pump from surge to engine.

hey guys im up to the fuel system part now :D got some questions

What lift pump can i use ?
What line do i use from the VL pump to fuel rail ?
What type of line to use or just efi hose ?

cheers :D

http://www.rollaclub.com/faq/index.php?title=Tech:Engine/A_Series/Installing_EFI_Lifter_Pump_into_AE86_Fuel_Tank

that should help heaps if you want to install an intank pump.

as a minimum use 8mm EFI fuel hose. you can run this all the way from external vl pump to engine if you like, but using whats known as bundi tube(i think) , basically flexible metal fuel line, is preffered.

hope this helps, good luck

im going to do a similar thing but with a ae82 intank efi fuel pump

For the Throttle Cablein my ae71 went down to the bike shop and got a 1/2 a meter of brake cable and two 'anchor' bolts. ripped it out the old cable. then ran the bike cable in. "anchor bolt" the cable for the accelerator then anchor bolt the bit from the throttle body to the bike cable.- have pics if needed.

For fuel i had the drain plug drilled and had a 12mm 90 degree barb welded on to it. i fitted the fuel pump on the same level as the drain plug- just behind the diff then ran a new 8mm fuel line to the rail (i doubt theres any point to the new fuel line though)

wat fuel line from the fuel pump to fuel rail do you use stock is to small right?

do u guys just run Efi hose all the way ?

http://www.efihardware.com/products/1384/aluminium-tube-38-10ft-roll

bundi tube its called, cheap as

i have just installed a 4age in my ke, and currently i am just using the stock breather line as my feed and the other bigger line as my return.

in a ke there are 3 pipes, 1 smaller one, 2 larger ones.

the engine has started and appears to run fine, but i havent driven it yet so time will tell if the small pipe can handle it.

i do have a roll of that budy tube though and will install it once its on the road etc.

I use the stock line in my KE, apprears to work fine. Could do with a surge tank eventually though, but thats nothing to do with the line. All im running is a VL pump, no lift, no surge. Hope this answers a few questions of a bare minimum that is needed.

28th February 2009, 07:46 PM
