engine options for hawkeye sti
so next year i will be upping the power on my hawkeye to around 450-500bhp but im unsure of which way to go with the engine, i was going to replace the rods in my current engine and give it a refresh whilst its apart.
what would be needed to run a 2.1 stroker in my car? i was talking with a highly rated engine builder about this earlier this year and was told that unless i have a syvecs it wouldnt be possible as the 2.5 DBW cam triggers are 3 wire and the 2.0 are 2 wire and not interchangeable. also the front left hand cam pulley trigger is not on the 2.5. is there any other ecu that could sort this? really liking the sound of the link g4 ecu at present.
i do love the torque of the 2.5 but hate the feeling in the back of my head that at any point it could fail as the bore-wall thickness is wafer thin.
i think the 2.35 engine may be out of price range from what ive read.
i can budget around £10k for this at the minute.

Sell up old engine and used towards rest of build/ donor parts etc. Budget probably won't stretch for the turbo capable but doing the main build the way u want then upgrading at a later date to get the power u want

Darton (or otherwise) liners are a massive expense and overkill at this level, CDB is far more cost effective and works
personally you would only liner a block you were trying to extract the maximum from or to recover a damaged block........

i will have the engine compression and leak down tested before sale for new owners peace of mind
