Im using the t04b at the moment but want to go with a gt35 or gt30 ballbearing turbos...

ANYONE KNOW????

anymore guys using the gt35 or gt30s some good power getting made guys my crank and bearings have arrivedfrom the states so just waiting on engine builder to finish up and throw it all back in car but im still undecided on what turbo to go with ?

the t04b pulls hard all the way to 7200 rpm rev limiter but as its old style bearings not getting full boost till 4200rpm hoping with a new ball bearing gt3540r i can get 18psi by 3800rpm and still pull till 8000rpm

im using the t04b at the moment making 218 rwkw on 16psi forged bottom end, custom cam,microtech,tr magna head,front mount cooler,not sure on injector size but there big makeing full boost by 4200rpm with a ar.50 rear housing thinking of going with the gt3540r but i want to know when it will get ful...

is there any diffrence in the crank shaft through the astron motors?

at what rpm are you getting 18psi by and is it dropping off high in the revs or pulling hard all the way
