2001 civics have a 9.9:1 compression ratio. What is the max psi for this compression, considering everyday driving?

rtype11

9psi with half assed tuning shouldnt blow up on you too bad.

with that t4 in your icon no more then 10psi on that D17 u may not get boost to 5500 rpms

What do you mean??? until 5500rpms??? Please explain in detail, I've never heard of that before

our little dinky 4 cylinders don't produce enough exhaust flow to spool a turbo that big quickly.........especially a D17. Now an super-double-whack H22 on the other hand might.....

DLB1994

right it wont spool up in to vtec u need a t3 or a t3/t4

A small t3/t4 (.48 ar) with a big exhaust spools very nicely on a d-series honda. Any larger though and its a huge lag monster.

Personally, i think a turbo like a big t28/t28, or a t28/t3 would be awesome on a d-series honda on the street.

Or a small T04E as was reccomended to me with a .48 A/R

Yep..thats the turbo i have. t3/t04e .48 a/r with a 54 trim. Its a very nice quick spooling still has lots of ***** at high rpm turbo. Awesome for high hp street driven d-series hondas.

I also think it would be a nice on a b16a, although most people run much larger turbos. I really like a quick spooling turbo.

Not so much larger, but the A/R would definatley have to be changed to at least .57 or .63 for the 8k+ rpm of a B16.
