wasup guys, i have a built rod and piston. I wanna aim for 450whp here in the shitty 91 octane. What is the best option turbo for my goal. Any help would be great. I also have search but with no to little help. Remember guys, my pump gas is 91 octane, and i want my turbo to be below 1000 please, with quick spooling too, about 4.5k or somthing...

 

Im using a Bullseye S256ETT and it will do what u want and makes a bar of boost at 4k on my B18c4 with a topmount mani and 3 inch exhaust. Im really pleased with it. I do get creep thouh so u will need a decent sized wastegate. I run a precision 46.

 

Have you checked out the precision 6262?

 

will it do it on 91 pump gas though....

 

Thats what I would recommend, the S256ETT. The Precision 6262 is just plain overkill, its a 750whp turbo.

 

Precision 6262 is too big. something a bit smaller like that Precision 5857, S256, and Silver surfer could do that though. You don't need more than 58-60lbs/min

 

I'll add my vote for the BW series, but I would get the S258 since you're trying to stretch its capacity on pump gas...It should do what you're looking for
