Let me put this in perspective... Most single turbo Supras run a smaller turbo. Your boost curve and power delivery would suck horribly a lot like a S/C . A T3/T4 is the way to go on high HP small displacement engines IMO. Something like an SC/50/32/34/44 would probably more than meet your needs. All are capable of 400+ WHP.

don't you mean larger turbos? my buddy has a .20 over built 2jz with a T-88H... you need nitrous just to get off the line, but once that thing spools, watch your ass...

Even with ball bearing turbo and doesn't the size of internals of turbo like fins, and ect... matter on spool time?

Yes, ball bearing setups will help but a big turbo is a big turbo and there will be lag. if you have not already purchased one we have a manifold and a t3/t4 from the UR gen 1 kit for sale. It was dismantled, cleaned and inspected. the Hot side was sent off to Swain tech for coating and the the other side had the welds cleaned up and was polished. Very nice looking and should meet your needs nicely for a savings.

At any rate, I would set your Hp goals and go with the smallest turbo that will stay in it's efficincy range for your goals. Wouldn't you rather be spooling a grand sooner and save some bucks in the process?

so is a T-61 bigger than a 60-1 then? I am running an extrude honed 60-1 (manifold is extrude honed as well) , hits 8psi around 5500rpm. I don't know much about turbo's themselves, can't read compressor maps or any of that nonsense, so I'm curious
