GT2871R vs GT2876r

[playastarkz123]

Hi i have s13 sr20det motor. Im in looking for a turbo capable of making 400-450 (the more the merrier) hp safely with minimal spool time. I have heard that the 71r exducer will allow me to spool faster than the 76 but how signifcant is this difference? a few hundred rpms? is that really going to effect me much? Im also planning the match this turbo with sard 850cc injectors and either 264/264 or 272/272 cams, i figured the more aggresive cams will help me to reduce spool time

I want to drift the car just for fun but it is also my daily driver and so reliability is key

i also want to be as fast as possible in the 1/4 mile

I was wondering if you can give me some input as to which route i should take to achieve my goals

thanks

You will max out a GT2871 .86 around 420hp

Don't know about the 67 but neither of these turbo are "minimal spool time" unless you motor is built up

Aggressive cams DOES NOT make a turbo spool faster...if anything, it makes turbo engines run less responsive. Itll make more power up top but you will lose low end power.

Personally, get a GT3071R, go topmounted T3 manifold and external wastegate...stop wasting money into a bottom mount T2 flanged manifold.

+1 the T3 .63 will spool faster than the .86 t2 and make more power at that.
