I just finished another 200sx SE-R. This one has a ballbearing GT series turbo. It's the GT28RS with a GT30 compressor upgrade. It's good for around 390whp at 20psi on an SR20. The upgrades to this car include:
Cryotreated SR20DET pistons
SR20DET rods
SR20DET head with porting done by Polk Performance
1991 SR20DE intake cam
GTI-R manifold
GT28RS turbo and GT30 compressor with 9psi actuator
3" full exhaust and downpipe
Unorthodox Racing pulleys
SR20VE VVL oil pump
50lb MSD injectors
FI-R fuel rail
Walbro 255lph pump
Aeromotive FPR
HKS Type R BOV
Jim Wolf Technologys ECU 50lb 4 bar
Mustang Cobra MAF
ACT clutch/pp
Greddy Profec B
Greddy Turbo Timer
Autometer- EGT, boost, oil pressure
Cometic metal head gasket
Forge Motorsport FMIC
FI-R intercooler piping
Full polyurethane suspension and motor mount bushings
Ground Control coil overs and KYB struts

I'm not very happy with this car.. :-p

Is this guy throwing up "gang signs"?

VVL oil pump..
We went through 2 attempts to rebuild his stock SR20DE motor.. However, we had an oil pressure issue with it after 2 attempts to build it. The second time we had it built, the entire thing was blueprinted... and we still had an oil pressure problem. So, we took the block out, and had it examined. It turns out.. there was a hairline crack in the block that was leading to an oil passage. When the block was cold... it would stay sealed.. But when the block would get warm.. it would expand and oil would leak from the crack into the oil pan. We determined that this has got to be caused from him overheating the engine earlier before he had brought it down to me. So, after a new block and high volume oil pump, it now makes well over 100psi of oil pressure anywhere over 3000rpm. Hell.. it made 25psi of pressure just on the starter.. :-p Thanks to the guys over at Polk Performance for the blueprinting and head porting work. And thanks to my buddy Tom over in Cali for providing the VVL oil pump.
