So then, why do hi powered n/a cars have hi compression? like the z06 has 11.0:1

That doesnt make sense, any engine n/a or not creates vaccum when the pistons are moving down drawing in air. High compression would help turbo lag since you'll have better exhaust pressure to get the turbine moving. But I would think displacement has the most effect on turbo lag since the smaller an engine the less exhaust pressure it has to utilize. |

high compression has similar effect to a turbo, its all about optimum air/fuel mixture. A turbo is just more efficient in the way that it creates a high compression engine from a low compression engine by utilizing otherwise wasted energy. |

I didn't say high compression wouldn't help turbo lag but the difference is trivial and it's dangerous to your engine. When you have a turbo'd car- with no boost pressure it will run MUCH worse than it would NA simply because it has to go through many more feet of intake piping- past a nonspinning turbo, and then into the manifold. It's actually really not the length of the piping, but the amount of curves and therefore surface area. Finally, compression point is almost moot, since the vacuum is there and air can't easily GET to the engine- this is turbo lag. |

I know what turbo lag is  And I know your looking into a setup now so Im sure you've been doing alot of reading, just the way you worded the other reply didnt sound right. In the end most things are trivial besides the exhaust pressure and size of turbine being spun. |

Ok.. thanks.. the best way to learn is to venomently defend the idiocy you've learned so far so the other person hits you over the head with the correct information.

Not to piss anybody off, but you guys are rediculus. Give your F***ing opinions and shut up. How do you think the person who's posting feels about this place after he tries to get information for help. Come on people, Coomer just had a huge post about this not to long ago. I want to take favorties about who's right and wrong, but that's also rediculus. Come on people, we're a 6gc community, FAMILY. Be cool with eachother, sometimes i get real easy mixed feelings about this site when i see stuff like this. That's my whole dollar.

I agree. That's why I left the topic. If someone won't accept you are right then theres no point arguing further.

That's not what i was saying Kamix, and you know it, that was just another childish responce. If someone isn't excepting you're right, then that's just to bad, you gave your opinion. If you have good hard info (in written form), then bust it out, but other wise, "give your opinion and shut up."

Oh kinda like you gave your opinion above? Shouldn't you be shutting up now? Of course people are going to have differences in knowledge, I was with Kamix on that and he did bust out the factual information to prove his point. |

so after all the arguing and disagreeing im still asking the same question?
what do you guy's suggest i do with my bottom end to build it for the ripps' s/c? Noob ?: if i get pistons and stock compression (that possible right) can i lower compression later for the s/c give me a lists of stuff i need to buy for my Bottom end, i am completely clueless besides rod's and piston. I know im suppose to buy them but dont really know what is good for my soon to be s/c car. I HATE BEING A NOOB -------------------- RIP-1995 Toyota Celica GT
