whats the difference between uk and red sti inlet manifolds?

any performance gains?

can a FE manifold be easily put onto and early car?

No difference

92 -96 are same 97 -98 will fit 92 -96 and vice versa but the throttlebody / tps is different.

 

V8 STi no longer have the TGV.

 

But will not fit an early car which he is refuring to.... so not relevant

Well I'll just go crawl back under my rock. Early cars suck!

 

So a sti4 manifold coversion with FE turbo would be relatively straight foward?

 

Realatively.... the TPS will need some work depending on which ECU you are using.

BVM.... Tell me about those early cars sucking

Hi

Im doing the same upgrade at moment..i have a 95-96 wrx with a Z4 ecu .
I have a manifold off a 98 wrx but TPS has only 3 wires on it and original has 4 .
How do i get round this ? is the 4th wire the idle position sensor as looked on wiring diagrams and the only difference i can see between the early and later models is that ealry ones list a idle position sensor .
Are the outputs the same on the TPS ?
Also do i just put original wiring off old manifold onto later one ?
Another other probs to look out for ?
Im doing this so can fit later TMIC and in the future fit front entry turbo .
Many Thanks
Karl
