Ive read all about dooing the swap from S4 to S4 but whats needed to do S4 to S5. I have a 86 NA and im looking at buying a J-Spec 89+ TII Motor so i figure il need a TII drivtrain and a 89 flywheel and clutch assembly and ecu. If i get a 89 TII ECU will i just be able to plug and go or am i missing a step here? What other problems would come up durring the process of the swap?

 

You will have one hell of a time doing it. Stay within your series to make it somewhat easy. Read a lot more than you have now and talk to people that have done the swaps.

 

whos done the swap?

 

I am so FRIGGIN tired of you N/A guys contributing to the decline of the TII species by doing these TII swaps... Just BUY A TII with a blown motor and rebuild it for christs sake and either sell your N/A like i did or keep it for a daily driver. AAARRRRRGGGGGGG!

Can I swap a Turbo/Jspec/13BT/etc into my N/A?
Yes, check these links:

You will also need a check valve for the brake booster or the TII brake booster line.

I have the series 5 ecu, harness, afm, boost sensor etc. you will need. The swap is not hard if you have the right parts. Even if you don't, there are ways to rig things so they will work.

 

AARGH!
