i can get a Brand New Garrett T3/T4 57 trim turbo off of Garrett Distributor (Supports 450 hp)= $520 but i think its set up for full boost at 2500 rpm which i prefer 3000 rpm full boost. but is this turbo too big for our car?

 

full boost at 3000 RPM??? no way....
you'll hit 3000rpm full boost with something smaller

 

lol... you will not get full boost out of that motor at that RPM's;. I don't think I even make full boost on that turbo at 3k. You have bad info.

 

reread what i posted. i said it has full boost at 2500 rpm but i prefer at 3k what does the norm civic with turbo boost at?

 

you need a little more research....
with my sc50 .63 a/r im reaching boost like after 4500 rpm

you can get full boost faster with a smaller turbo.. that is quite big for a d16

reaching full boost is totally dependant on everything BUT the turbo...
a 5.7 liter motor with spool that turbo much faster than a 1.6 liter

 

the turbo was for mustang v-6 to spool full boost at 2500 rpm but was trying to coompare this turbo in a civic. would a tdo4hl turbo work well on a civic?

 

Your prolly gonna have to get a smaller turbo for a "d" series. That is just too big.

 

im running a big ass turbo, but then again my setup isn't stock...
check out a t25 or maybe even a t3 .48 for something to spool quick

 

That doesn't say much... what compression?

There are a lot of factors that contribute to how you spool the turbo. Seriously... research.

 

since ur so educated then give me the scoop to save me time. so if i want only like 50 hp increase due to stock engine and like full boost by 4k rpm then go with a t25 with .48?
