how`s spool time compare to .48/60 in a Z6?..any of you guys tried?..
coz i a actually got a .48/60 on hand but then it looks like i will need a lot more boost then i expected to hit 250 + whp.. (12 + )
will a .60.63 fits in more? .

 

I'm gonna say go with the 48/60, unless your drag racing the car only.

 

yea. through of it but i`ve seen ppl going at like 15 psi to get 250 whp..

 

Go for the big one
I'm going T3/T4E 57 trim....AR turbine .48
Just cause I practically got a 42/48 turbo and am going to get a T04E 57 trim housing, wheel, etc... and slap it on

 

I got one of those babys in the closet waiting to be installed(60-63) on the crx. waiting for the intercooler to arrive. I dont think its too big. I think it all depends the overall horsepower goal you have.

 

I have a T3 60 trim .60/.48 and I think it's a perfect turbo for my Z6. It spools pretty well also(full 9-10 psi a little over 4k). If I turned the boost up to 13-14 psi I could get 250whp out of it easy. Your turbo should work fine so why don't you just turn the boost up more?

 

thats great you have a housing a/r your shooting for but without knowing the wheel stage on the turbine side or the wheel trim on the compressor side its like throwing darts blindfolded.

 

50 trim / stage 3 wheel.

 

i have a 60/63 on my Z6...will be doing some test/tuning monday/tuesday...i will let you guys know...

 

so let me get this right. you have a to3

with a 50 trim .60 a/r housing on the compressor side and a stage 3 turbine with a .63 a/r. dude that turbine is to big for a z6 1.6 l unless your revving to 8000+ rpm. id go with a .48 turbine housing with that stage 3 turbine wheel.Who speced your turbo ? a stage 1 turbine with a .63 would have worked better.
