Got the hog running last night HKS GT2540, HKS dump pipe and a rom tuned ecu, the wg is set on about 12.5 and it ****ing hauls *** spools WAY quicker and topend pull is insane, i cant wait for some fc 550's and about 16-17 psi should meet my 320whp goal hopefully. I love that this turbo is about as direct bolt on as they get for the rb20-25.

One thing i noticed is people talking about how there car seems like it "has run out of steam" about a year after i put the motor in the tach would go to 8 no problem but recently i noticed it has gotten kind of "ka" style in the uper rpm's slow and ****ty, well now it like a virgin again its hard to keep up with the rpm's, so i guess my problem was just a ****y old turbo....and when i shut it down after getting home as i was walking away you could hear it spinning lol, now i need a turbo timer damnit.

sweet sounds like where I am going with mine. Im using the hks gt2530 though. Already have the rx7 545cc densos and the z32 mafs, just need a rom tune to install them. What kind of ecu tune are you going to use? Power FC? rom tune? something else?
