ok my parents and the city are being *******.. i have until like 1 pm to get this damn 86 torn apart and in my garage before i get it towed off or before my mom shoots her "mechanically inclined daughter" (she hates that! at least im not a stripper though... geez she should pick which ever she likes best and ill do it).. back to the point...

i know i need the nose, ***, lights, tranny, clutch/ flywheel, interior stuff, and hatch lock mechinism (sp)

im gonna try to get my 90 put back together and do the auto to manual swap.. however if i put an s4 motor into an s5 i have to change the computer too right? so i dont wanna do that so is there anything else i could pull and use with out having to changing the computer???

oh and im pulling the motor bc i want to tear it apart and learn more about it.

 

Is it blown? (the motor). I would go and find a core from a salvage yard or possible one donated from the forum and tear into that. No need to tear apart a perfectly good motor if nothing is wrong with it. And I do believe yoru right about the computers as the they run different impedence on the injectors for one. Oh yeah, don't forget about the flywheel and front counterweight also.

 

oh no the motor is already fucked... i wouldnt do that to a good motor


thanks

 

Now you got me thinking. Is there a big difference from the s4 block to the s5 block besides hp? I'm wondering if you could swap intake and injectors also to get around swapping the computer as the s5 intake is probably better flowing than the s4 intake. The only real question is will the s5 intake port match the s4 motor. Hmmmm........

 

heh.. what CAN'T come off?

Take all the following:
Fenders, hood, doors, rear hatch, front/rear bumper cover (and supports), engine and all things bolted to the engine, tranny, shifter, seats, dash (yes the dash), computer(s), pedal assembly with brake booster/cylinder and clutch assembly, ignitors/coils, charcoal canister, radiator, A/C.. well.. leave that crap behind, rear storage areas, steering wheel, all lights, any bodywork that comes off, fuse panels, wiring harness, any extra gauges, sensors, etc..

Leave the carpet (crap).. then send it off to a junkyard and pray they put it under a tree so it doesn't get TOO rained on.. then go back when you got some $$ and buy it, take it to a place that does media blasting (like sandblasting) and blast the entire bare frame, coat it with a little protective junk, and start turning it into a SCCA Production class race car.

 

You might be right. You would have to swap AFM, injectors, etc. Also, the S4 has a mechanical OMP, unlike the S5.

 

take the mechanical omp and front cover off the S4 and put it on the S5... The blocks are identical in every way except the front covers. The rotating assembly is different from the compression and the weights of the rotors and subsequent counter weights.

 

well my parade got rained on... the tranny wont swap with out making a custom crossmember and not many places have the equiptment to do that... much less the time... and i dont have lots of money... so i pulled a few things off and its goin bye bye.... im trying to save up for a convertable t2 and im selling the miata

 

the crossmember is a breeze don't let that stop you

going from an s4 manual tranny into an s5 auto? everyone is making it sound like its not compatable and it takes lots of money to get it done the right way... ive been told i can just buy a 1k dollar 5 speed and work on that instead of causing my self a head ache... please correct me if i am wrong

 

This is what I'm using. One end bolts to the stud from the manual tranny and the other bolts to the auto cross member.



I believe the s4 tranny will work as long as you use a flywheel from a s5. (but don't quote me ) A more expensive option is to get a lightweight flywheel and use the counterweight from the auto.

 

[bnd] here did u find that ????? i made my own crossmember, but i like the way that one looks got a link?

btw,garlandrx7 it isn't that hard (not sure what diff would be for swaping with and s4 (i think u need the s4 flywheel and clutch componets to do it)not sure though) the hardest part for me was the pedals, it only costed me a little over $800 thats including other parts not related to the swap that i need

 

It's a lower engine mount for a Cavalier from RKSport. I got mine from a friend that sells aftermarket parts for Cavaliers.
www.rksport.com
It's not quite a perfect fit though. It's actually 3/4 of an inch too short. I had to remove the bushings from one of the ends to get it to fit.

Once you get the steering coloumn out of the way, the pedals are easy. At least it was for a small guy like me. The final total of my swap was $1000 CDN. Which is around $650 USD. But I ended up with a transmission with worn out bearings

 

i guess i got lucky mine was rebuilt before i bought it....


damn almost $90........ i'll keep my home made one
no one looks under there but me anyway

 

You got a picture of how you made yours? or the basic shape at least?

GarlandRx7- God damn strip that bitch out. I had this 87SE for a parts bitch i striped out, and go damn i have a whole FC in my garage i swear to god. LoL. When i towed that bitch off, i was driving with the steering wheel bounchin' around, only pedel left was the brake, no seats, doors. I was lucky not to get arrested that night, LoL. Good luck

 

GarlandRX7, what condition is the rear carpet?

 

it was in good condition but the car was towed off today... sorry

 

Kevin Landers sells the braket you need to do a auto to manul swap. Don't let peole talk you out of doing anything to your car, because it's your car and if you like to work on it what's the big deal? I just did a NA/t2 conversion and it's NOT VERY HARD, I am about to start on a auto/manual swap and that doesn't sound all that hard either.

www.rotaryresurrection.com-has good how too section.

 

Damn...I spilled beer all over my buddies FC and now I am on the hook for a new carpet...

 

yeah i saw that website too before, but since i dont have all that many tools (close to none) or space to do all this work (my mom doesnt like me working on cars) i gave up... maybe someday when i have my own house i can try it thank you guys for your support though. and jrat sorry man...
