What is a crazy boost level
and someone explain why a lower compression is better for a turbo...like the pistons from turbodiscounters 8:5:1...
would it still be ok to boost a high compression NA car?

It answers all your questions and more. It's a very good FYI. On Hondas none the less.

anything 9 and up your gonna have to totally redo your fuel system, because or civ's dont have a return fuel line. which means more money your gonna have to fork out. like the more boost your gonna want, the more money your gonna have to dish out for the car to be able those high levels of boost

I say... 30psi. Basically the maximum that one of those upgraded Eagle blocks can withstand.
If you're talking about a stock D17, then 10psi is insane. No amount of intercooling will save you from a blown head gasket.

on my wish list is a sleeved block from Polk Performance here in Arkansas. Its guaranteed to handle 60 psi all day long. They get the block sleeved by the same people that do work for NASA.
$900 is the price to pay.
AWESOME!
Of course, you would have to have an all-forged assembly to handle all that, but we can dream, right?
$900! gawd.

Yeah I'm going to get the internals first...slowly and one piece at a time.
Then the seeves and headwork.
I can do all the porting and polishing myself, but I will have to pay for the bigger valves and 5 angle valve job they do there.
After that its clutch and axles.
I know after that 450 hp isnt going to be too far away
Just a turbo install away that is....
I'm probably looking at at least $3500 before turbo.
But the look on my buds face when I dust his '79 Trans Am with a 455 Big Block!
Ah turbos........

Not to be conceited but I have nothing but the best helping me out with the install. My goal is low 13 (keep in mind I'm at 6,000 ft.)

Here is our project B18C1.

If you help me find enough info to push my friend to turbo his ex, I will be happy to answer all the questions you have about turbos.
