hey guys i need your opinion this ..

ok, im finishing my new built :

b18c5(itr) block gsr head
eagle h-beam rods
wiseco pistons(8:9-1)81mm
stock crank
golden eagle block guard
450cc
log manifold
3"dp
blox imf
etc...
on crome
ok now my question..

im using a garrett (TC4305 turbo) The compressor side has a 58mm wheel, 70 trim, .70 A/R, the exhaust side is 57mm wheel, 76 trim and a .82 A/R

http://i130.photobucket.com/al...5.jpg

if i change the exhaust side to a .48 a/r and wheel ,would it restrict me on the top end ???
it just seams that the .82 is too big

power goals at least 350whp and up @15psi???? don't know

what do you guys think?

With a nice engine build like the one you listed, i would get something else for the turbo. If i were you, i'd look into either a 57 trim, SC34 or GT3255e. Also, your injectors are too small for your goals. A set of 550s might get you there, but i'd opt for a set of 720cc injectors

 

thanks for the advice bro..
but i forgot to mention one think i ran out of money haha..
it was so post to be a budget built , so im stuck with this turbo for now ....

so you do you think??
change the housing??

 

I agree with changing out the turbo. I'd never even heard of that model, which tells me it's REALLY old.

Save up and pick up a good GT series turbo. IF you can't wait that long, a precision SC turbo would work as well.

 

i agree you can find t3t4 turbos in many sizes on here for cheap new they are only in the $500 and they will all get you to your goal and some

If he doesn't have the money for ANYTHING else, i dont think a GT series is in the budget I think you need to read before posting things

Also, for his power goals, there's really no reason to run a GT-R series unless its the GT28r. If anything, a used Garrett would do wonders for your setup and still not cost a ton.

 

i know what you mean man ...

the turbo came out of a 7.3 L power-stroke (garrett international),is actually a t4 on compressor side, t3 on turbine side.

 

exactly

now can some one answer my question please....??????

oh the other question i have is that when i spoke to the guy wo sold me the pistons ,he told me the if i ran the head gasket that i have (cometic .072 )would put me to 8:9:1 cr. but i think that's using the stock with .030 .

does anybody know with a .072 what cr it would put me on????

thanks in advance..

 

If you search "Honda compression calculator" on Google, you can find a few really good ones that will let you input the headgasket thickness along with your piston, head and block combo to determine your static compression

 

thanks bro...

what about the exhaust housing question???

.82 or 48???

 

anybody????
