gt3071r .82 a/r
 

So a friend is selling this turbo and since my current turbo blew I need another one and I was thinking of this but every where I read about the GT30R(which I believe is this right?) everyone is using the .63 a/r turbo . How much of a lag am I going to have if I were to go to this turbo? Is it going to be insane or within reason? I really dont want a turbo that hit full boost(18-22psi) at like 4500+ rpm.

Would this turbo be any good for me taking the above point about full boost into consideration?

forgot to mention this is for a ka24de with ross 8.5:1 pistons, eagle rods s13 cams and stock intake with a top mount log mani with a 38mm tial wg and a synapse bov.

tell your friend ill buy it off him.... and youll see 20 psi alot later then 4500 with this turbo...
