OK let me start off. I first had the 87 TII but it is a rust bucket. Everything has rust on it. So I placed an ad that I needed a roller. A guy in my home town gave me a a complete 89 N/A 5 speed minus some interior stuff. But the front end was damaged and it didn't have a title. So I also bought a 1986 Rx7 sport (the one that comes with 5 lugs all around and 4 piston brakes) also a 5 speed. The 1986 body is near perfect but doesn't have an engine or tranny. What I plan on doing is swaping over the engine, tranny, rear end, fuel pump ecu and hood from the TII into the 86. Is there anything on the 89 that I can remove from it that will better improve my performance on the 86?

Also when I'm done anybody want an 87 TII and 89 N/A rollers?

 

Good start! Um, take the mirrors aaaaaaand maybe that spoiler off the '89 :-D

Step 2 is have a big ol' garage sale of parts so you can fund the car some more.

 

Unfortunately somebody painted the spoiler and it looks like ***. And it's cracked at one of the mounting locations. My TII didn't have a spoiler either. Is this normal?

 

The majority of the S5 parts are heavier and softer, as far as performance increases. Mazda did some cost cutting and softening on the S5 versions compared to the S4.

So from a performance end, no. Not much you can swap over. Maybe the rear spoiler, body side trim and bumpers if you like them, but as far as performance the S4 sport is pretty well set up better from the get go.

Now if you use the S5 suspension it will be a little softer and more isolated, and some people really like that.

 

I plan on getting coil overs in the some what near future. Thanks for the info though!

 

u gonna use that tII hood?

 

yes i'm going to use it. The 86 hood is for sale though.

 

What if I swap radiators from the 89 into the 86. Any improvements there?

 

i would buy the 86 hood if it didnt have that retarded stripe and you werent in ar... is that arkansas i hate the states

 

Yea the stripe is more than retarded. Yes it's arkansas
