I really need some help. IM going to do this Saturday and Sunday.

And i need the car running by the end of the week. But i dont know what parts i will need. I have searched the forums for more info but didnt find anything.

I have a 86 FC blown motor. and a t2 motor with 66,000 miles. would it just bolt up?

Any help is much appreciated.

cool_as_crap

What shape is your n/a tranny? You could bolt it up yes, but might shorten the life of your n/a trans.
Or do you have the t2 trans?

TooDeep

I have the t2 Tranny, ECU, and drive shaft. Just need the LSD. i think.

Im also told i will need a new exhaust system

cool_as_crap

You would need the t2 diff, and the exhaust.
Do you have the stock dp? or have you no exhaust pieces at all?
Your stock catback *should* bolt up fine, but everything before that will need to be replaced.

TooDeep

I dont think i have any exhaust pieces at all. Maybe. I have something. just not sure if it came off the fb or the fc.

I dont have the t2 diff. errr

TooDeep

I really wanted to swap motors, Ecu, tranny. THen work on the other stuff i didnt have.

as i drove the car.

My lady will kill me if i have a non running car.

What year is your motor? You're gonna have lots of "fun" if it's an s5(89-91)

i was thinking that same thing MaczPayne

jonesfromindia

i know from experience, s4 exhaust is s4 exhaust. it sounds like **** with the NA system on, but i drove with it like that for 3 months. keeps the cops off my ***.

Motor is a 87. Car is a Clean 86. But bad motor and really messed up registration. going to DMV with owner of monday to work it out . If its possible.

I was converting my NA 91 FC to a turbo II FC.

I needed

-Turbo II Transmission (I had a rebuilt S5 Transmission)
-Turbo II Starter (I had a rebuilt starter)
-Turbo II Clutch assembly + Flywheel and counterweight (all ACT pieces)
-Turbo II Driveshaft ( I used a mazdatrix 2 piece)
-Turbo II Engine
-Turbo II Rear Subframe

Note: While you are doing this, i would recommend doing all the service work while the engine is out of the car: IE: Belts, fluids, plugs, wires, TPS Sensor (if it is going bad) etc.... if you want the car to run its best and be reliable.

I had all the above except the last 2, i moved out of my house and i sold the car for dirt cheap with essentially a beefed up brand new Turbo II Drivetrain lol.

The swap should be pretty easy since you aren't crossing series.

Use the N/A harness that's on the car, that way you won't run into alternator wiring problems. The N/A has alt wiring in the engine harness. The TII doesn't.

You wont have any problems with injector impedence, since 86's and 87's both have low imp injectors.

If you are using the s4 turbocharger, you might have to add a few things to use twin scroll. I don't know how off the top of my head, but a quick search of "swap + twin scroll" should get you something.

Ideally you should swap a whole TII driveline for this, but if you want to use the N/A tranny, that's fine, but use an s4 n/a flywheel and clutch.

That's all I have for now.

Here's the Factory Service Manual, it will help you a ton:

If you're using the n/a rear end, you'll have to get a custom driveshaft made to mate to the TII trans.

TooDeep

well i guess ill have to find a t2 rear end.

To clarify an earlier post, you don't need a TII sub frame. But it might be easir as the alternative is swapping out the NA half shafts for TII half shafts. Sometimes those half shafts can be a b i t c h to get off. Subframe allows avoiding that potential pita.

As to getting it done in one weekend, good luck. I guarantee, no matter how complete a swap "kit" you think you have you will for sure be missing one or two things. For instance, ASpec TII throttle cable if quite often forgotten. ASpec is different than a JSpec.

I need to get my motor rebuilt. brother said so anyways. so i passed on the $500 fc.

but if anyone is interested in talking to the guy and working out the pink slip ill give you his info.

im doing this same swap. except my car is an 87 s4 with a jdm s4 TII. the only real problem ive encountered is that the plug that plugs into the very top by the passengers right foot is like 1 foot short on the jay dee emm engine harness. now if all your **** is usdm, it should be a breeze. make sure you get the s4 TII knock box (s5 came with them built in to the ecu or sum **** like that) and as far as the diff and drive shaft goes, you can use your na diff, just go find the TII drive shaft take the base plate off, and replace it with the base plate offa your na d/s


wait, are you still doing this swap? cos i just read the last post hahahah

NO i have had this engine for a few years now. I have to research on how to rebuild it. Myself. And the cheapest rebuild kit i found was $1k .

I would have bought the car and did this over time as a project. But my woman wont let that happen. I would die.

So now im looking for a rebuild kit. and a 1st gen rx7. 1st gen will be my DD till i get the t2 rebuilt then swaped into that.

Funny story. (kinda.) My lady hates rx7s. And she asked why i liked them so much. i told her its because of the engine. Its not like anything else. Its very unique , and i cant beleave it works so well.

I showed her how Normal engines work. Then how a Rotary works. (off wiki) . And she was mind blown. She was ahh struck. Couldn't beleave i would like something so unique.

Pics for fun. My old project. ( t2 was going in that.) then lost the garage. T2 in the background.
was my brothers old car. left it in a field for 5 years.

Dont they look sad? Cause i have to rebuild my motor.
