I'm really not sure, I just recentley hooked up my greddy e-01 and found out I've only been pushing about 6-6.3 lbs.! Plus I just fixed a huge problem (that I didn't know I've had since i've had this turbo) My wastegate has always been a little open, so now I'm running alot quicker! Plus I can up the boost! But I really don't know about numbers I'm doing a built motor with new turbo set-up and dyno tune hopefully this winter. I'm waiting on some injectors and e-manage to come in now so i can tune it myself. I can out-run srt's, wrx's, and non-supercharged cobra's on wastegate so it's not bad! But right now my turbo needs to be rebuilt so I just ordered a gt28! Um, ya a thicker headgasket will lower your compression a little, but you should be fine running 6-7lbs on stock internals. More with good tuning. Heres a link to something you can read-up on to learn more about turbo's and parts, etc...http://www.beesandgoats.com/boostfaq/g2icturbo.html
