GR Supra 101: Routes to big power

Yup. I started having issues at 29psi+ 6,000rpm on.

M550i or M5/X5M LPFP pump is a nice OEM+ upgrade.

Yes same, ~28 psi+ on pure900 did it at 6k rpm

Thanks for the recommendations.

Having run a Pure700 (very close to the new 650) and now a Pure800... Skip the 650 and get the 800. More efficient, less bp, etc.

Just not the cast 800 unless you bore out the WG outlet before installing.

So for Pure 800 you would get the rebuilt 800? Are the reliability issues with the rebuilt overblown?

Is the precision raceworks stage 1 (28% increase over stock) pump sufficient? I'm staying away from PI, but want to maximize a pure800, ds25, and s58 inj setup. I'll be happy with ~650whp (I say this now and will probably get bored in 2 weeks)

But found some info on the Pure600 and 650

HPFP will help with added power under the curve in low to mid range. Injectors will help with more power under the curve 6000rpm+.

I run both DS25 + S58 injectors on Pure800, with E40 and 600whp+. Enough to make trans slippy slip.

Next would be LPFP.

is there a better option for a hybrid turbo to keep as close to stock spool as possible? Looking to hit 600whp with flex fuel + DS25 + S58 combo

Pure 650, pure 800, daw ultraflow x, etc.

Pure650 but would be pushing it pretty hard.

Pure800 isn't too much worse than 650, you get used to it. I come from big turbo 4 cyls though so none of the hybrids on the B58 are really "laggy" to me.
