This is what I have on plotting points, 3.2 preasure ratio. 46.575 lbs/min at 6800rpms and 33.98 at 5000 rpms. The only thing I could plot was the gt3071r, that's a bit expensive. Is there any other alternatives? I'm shooting for 405 bhp on my b18b. Although, by garrets equations I got 30 psi boost.
Help on what turbo size

the GT2871R falls into that same plot, as they both share the same compressor side. the GT28 is on the T25 frame, which is a bit less expensive than the T3 frame GT30 or T28 frame GT30 (because of machining work).
the problem? the T3 frame GT3071R has been said to spool slightly faster, as the GT2871R nears the flow limit of the T25 flange.
interesting, would you have compressor maps for other makes (ie..precision)? thanks alot
is the motor built?
Yeah, eagle h-beams, wesco pistons and crower double springs...
Does anybody else know any other turbo makes that would work?
thanks
thanks

should be able to give you a ballpark range to look at in the T3 frame world.

good luck!

Thanks man!
hmm....turbonetics ask for a to4e 60 trim on a 2 liter setup. But, garrett seems to be between t58 and t61.
where are you finding that garrett info?

Here's my variables, 6800rpms, 405hp, 11.5 a/f, VE .95, 100 degrees vm and 1200 elevation.
