RX87

I found a 91 GTU at the wrecking yard and I had some questions. I have a 87 GXL ,will the intake manifold interchange on my motor without problems, what other parts can I or should I get off of the GTU. I got lucky cause the GTU had the japanese circle stop lights and the stock wing, the only thing is the passenger light is cracked on the orange part. I really need to know because I was going to remove the intake so I might as well change it.
Thanks, Francisco

I'm not positive, but the s4 and s5 intake manifolds are different.

The S5 intake can be swapped into the S4 so YES.

FYI the circle tails are NOT from JAPAN then cam on A-specs in 89-91. They arn't JDM or any of that crap unless the car came direct from japan.

I know alot of people have ask the intake question already but i am going to ask again. What kind of power gain can you get from changing the s4 intake manifold to a s5 manifold??
