Ke70 Racecar Project

[David[RL]]

My 2T-B engine is seriously leaking oil, about 1 litre a day, the starter is dead, and many other problems

so I've decided to move all the parts from the ae86 ( 170hp 4age, big front brakes, coilovers suspension, hydraulic handbrake, rear axle with limited slip and rollcage if it fits )

so therefore I have some questions that might already been answered, but I couldn't find it.

 

ae86 parts, ke70 car

engine, front suspension, steering components, crossmember = bolt on

gearbox and gearbox crossmember = bolt on

tailshaft = bolt on or does it need to be shortened?

rear axle = bolt on

fuel tank with built-in pump = same size, so I'll guess it will fit? anyone done this before? what should I do about the wiring to the fuel pump?

fuel lines, return line and brake lines = I guess I could use my old brake lines at front, but what about the rear? And what about the fuel lines, my old wouldn't be thick enough I guess?

and the EFI ( CRAP ), everything in the ae86 is working, so I just hope it isn't very much cables not from the engine that goes to the EFI is it?

exhaust will fit without much trouble I guess..

I guess that is about all..

 

any comments, questions or ideas will be apriciated

 

I originaly planed to be finished within a month or so, but now I'm really in a hurry because my 2T-B engine is dead :\, so I plan to atleast take everything out of the ae86 this weekend,

maybe even be finished, I just don't know how many hours of work this will take me

and yes, I will take pictures :)

what's wrong with the ae86?

[David[RL]]

it's nothing wrong with the ae86 except it's 3 times more expenssive insurance

than the ke70... the ke70 is also in much better shape than the ae86, ( rust )

and I have to pay waaaaaay to much money to get license plates on it, and I won't risk weld on the ke70 chassi number on the ae86...

 

the ke70 is also a lighter car, so it will go faster :)

I also think it's nice to have a real sleeper, instead of a car everybody want to steal..

gotcha.

ok when i did the efi in daisy, i ran the fuel return line back to the tank using the charcoal canister vapor line. (don't know what kind of emissions equipment you guys have). the wiring harness was easy; the 1983 starlet efi was a factory add-on, i just snatched the efi harness, wired up the main relay, hooked up +12v, ign, start, ground, and a/c.

i used the in-line starlet fuel pump, but i don't know how well my feed is as the line is so small and THERE IS NO SUMP; i go around corners hard with less than 1/4 tank and it will starve.

i don't know much about the later corollas, but i don't see why the rear axle wont fit.

[David[RL]]

hmm...

I need to know exactly what to do with the EFI wiring thingy

do I only need to connect everything from the engine to the EFI, and then connect + and ground to the third plug on the EFI? or is it more? if so, tell me now! :) else I will just scratch my head all weekend and not getting finished before monday

[demuire]

Basically everything that is connected now in the AE86, you will need connected in your KE70. Probably easiest to transfer the wiring looms over too.

[David[RL]]

yeah, great, I will move everything over to the ke70

does anybody know if the dashboard fits or could be fitted in a simple way?

or do you guys just think it'll look stupid?

( I want builtin tachometer ) :)

[Medicine_Man]

I'd keep the KE70 dash in and look for a KE70 tacho cluster to swap into it..

[David[RL]]

okay, maybe 'carpet' it, using some sort of carpet for subwoofer box, I think that will look great :)

but as demuire said, change the whole loom.. I've just used 30 to 1 hour comparing the two cars.

things like dash, lights, etc won't fit, because of different plugs.. what should I do about that?

and changing the whole loom, is that the whole loom, including fuse boxes, etc?

I think that's alot of work with no gain what so ever..?

correct me if i'm wrong but I just don't see the point when acording to club4ag I can just connect the engine loom to the ecu, connect 3-5 cables from my old main loom to the ecu and that's it?

 

wiring diagram

 

also: do you have any ideas of where I could mount the ECU? it doesn't seem to be enough space where it is in the ae86..

maybe only put it in the glovebox?

i mounted my ecu upright (like a book in a bookshelf) in between the fuse panel and the steering column....but mine left hand drive.....

Edited May 27, 2005 by mikeys toy

[David[RL]]

okay hehe, ( mine is also left hand drive )

 

who wants spagetti for dinner?

 

 

this is on the engine loom, connected to the main loom.. do I need this to run the engine? if so, what should I connect it to?

or is it impossible to run the engine without the main loom?

 

 

what is this? it's on the ECU.. do I need to connect it to make the engine run?

[Redwarf]

If it's what I think it is, you will need it to tune the car properly. To set timing on an A engine, the idle needs to be slightly higher, and I believe that by shorting two of those connections, that's what it will achieve. Be safe, leave it in... :)

(Here endth my A engine knowledge.)

[mikeys toy[RL]]

i think that also kicks the idle up for a/c, power steering, etc.......

[demuire]

Rob: Remember when I was trying to set the timing on my car? Shorting the terminals didn't really do anything :)

 

David: My computer doesn't have that, so no idea. Looks like you have your work cut out for you! Sorry I couldn't be of much help, my car didn't have any of the bits yours has!

[David[RL]]

Now I've been working all weekend, and taken alot of pictures, but of course I forgot the camera, so I will post them later this week

the ke70 has now:

4A-GE with 170hp

T50

Coilovers with stiff springs and bilstein shocks at front

Big brakes at front, with vented cross drilled discs

ae86 discs brakes at rear

Quaife quick ratio steering ( about

Longer control arms

ae86 rear axle with LSD ( it may need to be reconditioned sometime in the near future )

stiffer springs and bilstein shocks at rear..

 

The tailshaft is not yet mounted and the electrical system is untouched, so I will soon be finished with the conversion :thumbsup:
