I would be curious to see the power difference between the 0.81 and the 0.59 A/R turbine housings. The smaller turbine housing will spool up a lot quicker but you will loose a lot of power at higher boost levels. Post some more numbers when you get them!
On an SR20 with a T3/T04E switching from a 0.63 to a 0.82 A/R turbine housing yields about 80 hp at 19 psi. The gain in power on your straight T4 should be even greater.
Are you looking for all out power or is it going to need to be more of a street car with less lag?
Nice job on the manifold and install. I like the polishing.
Peace

Thanks alot guys I dont see how I would lose power by switching to a 59 A/R the reason I didnt make anymore power this time was because I ran out of RPM the curve was still going up at 7500RPM.
This Turbo is not even at its best til 15psi at 10 psi its not even hissing. Hopefully John will email me the chart.
we also let off at 7000 the third run because the EGT got to 1350 f.
Is this high ? many other turbo car owners avg. 1600 f

1350 is way too low during a max power or a dyno run
1600 is where it will be at the end of a high boost run
that means youre actually working the fuckin thing
Do you have graphs of your dyno run ?? I would like to see how the torque of a built sr compares to a vg30.
ps- that sucks man sorry to hear that your turbo spools at 5800 mine is spooeld at 2400 =)
Congratulations on 270whp that is surprisingly good!
I cant wait till my car is actually finished again
front mount
more fuel pressure
larger fuel pump then gimpy tt pump
I am going for 400+ at the rear wheels and 500+ torque
then come the competition cylinder heads
at which i am going for 450 at the rear wheels of hp and stil 500+ torque
