XKR Super G... Going for Mach 1
any reason you didnt just go with the 18g's then. gaining 3-400 rpm of lag doesnt seem worth it. Heck the 16g woulda been an even better choice for 500 hp and prolly close to 800 rpm better spool.
I think all the new Greddy kits are 20Gs. Anyway, I've got a feeling Jay'Z has got more than 500 whp in that car whether he knows it or not (and I don't mean turning up the boost though I bet on his motor he could run 17-18 psi and 600 whp safely on pump gas). Jay, take it to a dynojet and see. I think you may have gotten "only 500 whp", but I'll bet you won't be able to dyno it for less than 550 whp at any other dyno you go to.

Ahh, I thought you could still get the 18g's. I'm sure he could run safely at 600 on pump. Thats why I was curious. Either way, its a lot of HP

Just the tuner kits include the 20G turbos. You can still get the 18G turbos with the other kits.
The only difference in the two kits are the size of the turbos, one piece downpipe, WG relocation kit w/ open dumps, no E-manage and no injectors w/ the tuner kit.

YOu post the date, i'm sure you'll have quite the crowd. Kinda like Lance Armstrong said he was going to ride at 5am from this park and 500 people showed up.
I'll drive down from NC, and prolly have to punk you with my stock block vortech! LOL
