As you all know iam planning on doing some engine work to the car, handling mods iam not to worried about its the Engine mods iam a wee bet unsure of, on the forums you read cars running at over 300 - 400bhp my wonder is long term how long the engine, gearbox will last at that kind of output before such time as lossing poneys or imploding.
You can take P1's as an example in standard form no mods you can expect to be replacing the bottom end aroind 40,000 miles. So with an STi modded to 300 - 400bhp can you expect the engine to one day so to speak give up the ghost.
