Default 99RS 2.5L stock motor build up questions.

hi all,

currently its a 99 RS-T .. bought like that, and the engine is in bad shape.

In college so i dont have the time to do a swap, was thinking of using the stock ecu on the block BUT build the block to handle boost. Using an SafcII to handle the car now, runs great! BUT i have questions about where do i get the parts to lower the compression, and raise the revlimit ...

The time saved from not doing a ton of wiring, like in a swap, is money saved for internals.

any ideas or suggestions? any experiences?

Check out:


See if you can source an EJ22t shortblock & re-use your heads. You may need to go aftermarket EM to raise the fun limiter.

Any of the turbo short blocks would be a viable option. But it would be best to move this to the AFI forum for the best input. And before you do, get together exactly what the set up is, as in what turbo, intercooled, what EM, etc. etc. Then we can give you a ton of advice...
