I have an 03 Elantra GT and am going to be turboing it this April. I have been getting mixed messages about rebuilding my engine. I wish to use 10-12 psi of boost and, up until now, planned to put a 3mm head gasket on it. I wondered if anyone here has safely boosted around this psi range on a stock beta WITHOUT a 3mm head gasket. I still plan on getting a tune, bigger injectors, cooler spark plugs and a complete turbo set up.
If anyone has done this, was it still reliable (did you end up blowing it up)?
