sorry it may have been posted but i don't know. but at 10psi on my 98 b18b i only made 229hp and 209tq isn't that kinda weird. here's the mod.

98 b18b
drag manifold
tial 38mm

That's where the power loss is right there. Go to a 3" exhaust and you'll see huge gains with a retune. I made 253whp/222wtq at only 8 psi on a very similar setup but i have a full 3" Kteller exhaust, 3" magnaflow muffler and no cat.

 

He's right, it is extremely difficult to make power on stock exhaust piping.

 

get rid of the catalytic converter

 

3" turbo back. nuff said.

stock clutch wont be lasting very long. a few power shifts and it'll start slipping everywhere.

 

stock exhaust is no good even when i was NA making 190/137, let alone forcing the induction! If you have to buy an exhaust you might as well step up to the 3" exhaust, but im running my old thermal 2 1/4" exhaust(no cat) and make fine numbers.

my torque even seems a lil high for only making 285whp, i dont always see torque around 225 in that whp range.....but every setup is different, and that was with a cracked manifold on the dyno, so who knows.........

the bottom line, go with at least a 2 1/4"-3" inch exhaust(if you plan on making even more power go with 3" with no cat)

 

is your turbo a b or e compressor housing, my friends h22 with the b housing only made like 249 hp at 10psi, very conservative tune. so your numbers sound about right if its a b housing.

 

run a 3" kteller and run it to a magnaflow muffler you will see great increases.

3" cat works wonders

 

either a new exhaust or a Ecut-out, but thats a whole nother problem itself.

 

alright thanks everyone i think imma go with a 2.5 or 3' piping and magnaflow exhaust and do a retune see where my numbers at. thanks alot

before you even think about making any more power, you will need to upgrade your clutch

 

you will see great increases in power with a 3" and a magnaflow exhaust let us know what ya make.

 

3 inch

12 psi:

 

sorri for the noob ? but what stage or what type of clutch should i get. because i wanted to hold up to about 250-300 hp and i also wanted for daily driven so if i go with the stag4 it will be too hard. what do you guys recommend. type of disc and plate.

 

my ACT 6-puck solid hub clutch works great to hold my power, but its a lil rough on the leg......not that bad, but im daily driven as well

might want to go with clutchmasters stage 4....it still has a sprung hub
