well if your after 150fwkw i'd go with a ca18det... they rev harder and easier and will easilly pump out 150kw on stock internals with the right support mods, ie. z32 afm, 550cc sard/nismo/gtr (gtr injectors will fit the ca's) injectors, bosch 044 or 040 fuel pump, re-cored t28 (if i was going turbo i wouldnt get a stock turbo or a hi-flow, i'd go with a re-core or just a bigger turbo in general), big fmic, airpod, skyline r32 or r33 brakes, coilover fully adjustable suspension (tein or hks), 9" rims, pump the guards out, 245/40/17
then you need a stronger box/diff which may also come with the ca18det
and about $10g later you'll be laughing!....
this car would be an absolute animal if it was done properly, hardly any drivetrain losses (in comparison to rwd), better traction off the line, car would be PIMP!
