That's a very broad question. I'm sure if I was running a bar of boost on one it'd last for a verra long time.

On my 3rd one in 13 months.


Not including running in miles

1st - 300miles

2nd - 60 miles

3rd - 4500 miles to date

They popped after some very very poor mapping , difference with the 3rd is it has been mapped by Andy F

The first 2 engines both blew a rod through the block

Sorry for the hijack Dannytwo.
Can you list who built your engine(s), so we know who is good and who to avoid. If you have had a failed engine and you know why, then please list that too.

Think if you've blown any through road use you need to speak to your engine builder or re evaluate your driving style!

'Standard forged'? There is no such thing. A 'forged' engine has forged steel rods, a forged crankshaft (both machined from solid billet, not machined castings) and forged pistons. Subaru havent made a car with a forged crank and rods.

They paid for the rebuilds, sort of.(they used s hit 2nd hand parts ie rods on the rebuilds when I had paid for aftermarket forged items)

It was worth the wait, I have an EVO X SST and my V3 STi puts a bigger smile on my face.
