Used a 2871 with Jun 256/10,5 cams on an otherwise stock motor, very impressive in a 800kg car.
No Dyno graphs but made 215kw atw at 15psi, messed around with higher boost & e85 with some good results but this is a daily driver & needed to have it super reliable.
I craved a little more power but wanted to stay at 15psi max so I opted for a GTX2976r, as I had no interest in going high on the boost, I ordered it with a 0.63 housing & T04B comp housing, capped it off with a SS bottom mount equil length manifold.
The results were more than exceptable 15psi by 4100rpm, 243kw @ 7100rpm.
I am thinking of maybe doing a cam change to the s4 perhaps or Tomei Pro 260/12 Hyd.
