hi fellas my mate said my engine is doing tell tale signs of headgasket failure he said if i hear water sound coming from what sounds like heater matrix when start up that my headgasket is on its way out how true this is i dont know but its a 2 liter twincam i4 engine got about 110bhp ??
thing is im looking to chage engine for a bit more power not too much i want a very resonable amout of bhp thats is 200-240 max and also i want lots of tourqe
what engine apart from a yb and 24 valve is best and must be lightweight and maybe id fancy a turbo was thinking a 2.3 dohc with a turbo any one messed around with sierras before would be much aprieciated cheers
