hi everyone, i am thinking of doing a TII swap into my 90 Vert. but was wondering if there was a big diff between the 86-88 model TII and the 89+ TII?? i was gonna get info on everything i need for the swap and go from there, but would it be worth it? or should i put in a 20B? or should i swap from a 89+ TII? dang sooo many things i need to learn about the diff TII's help please anyone!!

1989-1991 Kouki turbo motors are rated at 200hp.
1986-1988 Zenki turbo motors are rated at 182hp.

There's some minor differences on why it makes more power, but I doubt you want all the nitty-gritty.

A 20B swap is going to cost at least $15,000.&nbsp I hope you have that much money to start out with...

wow holy cow...i just saw an add for a 20B cosmo engine for about 1500 but didnt realize i needed more. dang. hey those kouki and zenki motors, are those japan stuff? i am looking at buying a TII and doing my swap, but i am in the U.S. and the cars are running pretty good according to my brother who has known the owners.
any other info...please post em.

Zenki just denotes 1986-1988 models.
Kouki just denotes 1989-1991 models.

Aussies call them Series IV/Series V just to denote the differences.
There is nothing really special about the J-spec engines, except for the fact they have limited emissions.

wow o.k. but would it be just as good to put a 86-88 TII swapped into my 90 N/A Vert? or would it suck bigtime...better to go with diff setup? i dont want to make my car super fast or anything. just enough to spank some people on my streets and maybe an occasional drag race. without all the heavy maintenance i hear with turbos i guess...i dont wanna be complicated. any insight?

 

Swapping a 13B turbo to a N/A is more than just motor swap. If you haven't done any motor install or haven't worked on a rotary, you're in for a long mess. You better go buy a few cases of beer. You need to get the ECU for the motor you plan to use along with the wiring harness. Good luck in finding one that's not hacked. I'm not sure if the tranny is able to handle the extra power.

 

he could go to carb way...

 

i know...there are numerous posts and such on exactly what i need to do the swap...i was just wondering if it was worth it to swap a 86-88TII into my 90 Vert N/A?? or should i try to find a 89+ TII and do the swap?? or it doesnt matter which year???

 

Won't make a difference. With a stock turbo, both engines run out of steam at about 6500 RPM anyway. The S5 TII offers slightly better engine control and higher compression, for very slightly better gas mileage on the highway... other than that... crapshoot.

o.k. i guess ill hold off on any turbo swaps for now...till i am more informed and am sure what i need. thanks for all the help everyone.

 

For a good TII swap you'll need the tranny and rearend too. It's a pretty big project.

Good luck

 

yeah was gonna go buy a TII and do it...

 

You'll have a lot more luck finding a Series 4 TII for the swap. The Series 5 is going to cost more and probably isnt worth it.
Put and exhuast and do the fuel mods to run 10psi on the Series 4 and your already making more power than the S5...
