Isn't op asking about what engine to use for a racecar? Besides I said that this is what I have heard (which, Grant, you left that out when quoting me), I was not stating it as a fact. However you said you should be putting down about that range on you're car? I guess we can wait and see how it holds up. Fwiw, my motor for my car is getting forged internals, this will not be such an issue for me (more worried about the trans and rear end holding up).
JP, care to weigh in on this? I know you have done some budget 4g builds in the past, maybe you have some insight you can provide.
