hey just wondering what yall think. i was reading that some found a .42/.48 to be a little small (lost maybe some power about 6500), but then again some found it to be good. and then some are saying that .48/.60 might be a little big. i want to have a large powerband 3-6900k....so this size seems to be good for 1800cc kinda in the middle of the two

 

thats not too bad. a 60/48 would be fine, a 60/63 would probably be ideal.

I have a 42/48 I'm puttin on now...I have a feeling im going to be disappointed. I had a 60/63 on my old hatch and it pulled hard and made 253 hp at 9-10 psi

 

wha motor did you have?

 

What turbo do you have? The A/R numbers don't tell us anything at all. Compressor wheel size and turbine size would be good if you want to know how it will work on your b18. At least the family the wheels are from...t25, t3, t4?

 

the old one was a 95 b18b1.

this one is a 92 b18a1.

 

here is the specs:

compressor-whl dia:56mm, trim:55, a/r:.53

turbine-whl dia:47mm, trim:72, a/r.47

 

ttt

 

As BailHatch asked -


what turbo are you even using??? t25/t28/t3-t4 ????

You can list AR all day long, but they are all relative to turbo size

 

its a garret GT20. nobody know anything about them...
