A Couple Q's
 

First: I have come to notice that most turbos have an ar of .48 turbine side(wich makes for faster spool), is this correct?? And the bigger the Compressor side the bigger the boost? Correct?

Second: Well to be honost i forgot the second one i'll get back with ya when i remember. Sry...

Thanx again

a smaller turbine a/r will generally spool faster. A larger a/r compressor will, uh, how do I say this, the boost will hit a little harder than a smaller a/r. You have to look at the wheel sizes as well.

figure out what car you have. :D ;D
figure out how much you wanna boost.
Do you want the boost to be instant and fall off at high rpm or do you want a little lag and boost to pull all the way to redline? Get all that info and someone will suggest something.

Ok... Well it will be going on a 90-91 B16a in a 90 Civic Hatch. Stock Internals, Looking at about 8-10 Psi. And yes im looking for a all the way through boost turbo... Redline at 8200. So i want something that will spool up decently quick and yet have boost through the high RPM's.

Im bascially asking this to learn about the AR #'s and such. Oh and im shootin for about 250 WHP. Tanx
