| my sport 600's are t28/t28 with a .63 A/R housing - standard turbo design doesnt flow as much as the larger BB compressor wheels - cant handle high boost that well ( past 25psi ) - 270 degree thrust bearings the GMS GT675-R has
GT30/GT25R with a .64 A/R housing - ball bearing design
flows better than the sport 600's at high boost - similar lag to spool as compared to sport 600's - quicker spool response once spooling - slightly more power than sport 600's - can handle high thrust loads at high boost - can handle 26-28psi - 360 degree thrust bearings
the GMS750-R has
GT35/GT25R with a .64 A/R housing - ball bearing design flows better than sport 600's at high boost - additional lag to spool due to larger compressor wheel than sport 600's - quicker spool response once spooling - more peak power than GT675 R - can handle 28-30psi - 360 degree thrust bearings
the JWT sport700BB
has
GT25/GT25 with a .86 A/R housing - ball bearing design flows better than the sport 600's - additional lag to spool due to larger a/r housing - quicker spool response once spooling -potential wastegate issues - similar power to GMS 750 R if it can hold stable boost past 24psi - 360 degree thrust bearings the HKS2530's has
GT25/GT25 with a .64 A/R housing - ball bearing design flows better than the sport 600's at high boost - better lag to spool than sport 600's - quicker spool response once spooling - less peak power than GMS675-R in theory due to smaller compressor wheel - but builds boost faster - can handle 24- 26psi ( smaller compressor wheel ) ??? - 360 degree thrust bearings
the Z1 stage 3
has
GT25/GT25R ??? with a .64 A/R housing- ball bearing design basically the JWT sport 700BB with smaller compressor wheel
similar performance in theory to HKS2530's with my setup - specialty z inconel manifolds and SGP motor - 30psi boost range and anticipating having to get the new specialty z 5 bolt downpipe ( lower lag ) if I can get the same power band ( at a minimum ) that I have now w/sport 600's w/ minimum additional lag ---the turbo setup in theory I should get would be the GMS 750R which potentially could give me another 50-75 rwhp ...is this correct thinking ?
