I looked into that also Dave. I another member tried it and confirmed it didn't fit. The borg compressor housings are just too big.

 

Bigger turbo and C16 will get you there. Everything else can stay the same.

 

Your current setup on c16 will probably get pretty close as well.

 

If you really want to push it 600whp migh be possible with your current gtx3076r. But the small turbine wheel is really holding that turbo back.

 

You should be close to 600 on race gas. On my 6266 jb I made 580 on c16. Now I have the 6266 gen 2 and will be tuning Friday on c16. Should hit 600 now. Also, did you ever upgrade your valvetrain? We will be testing the projay manifold soon hopefully on the s2000's since we seen a big gain on all our K cars.

 

No my head is untouched. No need to change on an ap2.

 

I'm at 600hp on this turbo

GTX3576 with big 1.06 hotside

I'm sure out setups are pretty different, so hard to compare

I'm on E85, but only running 15psi
Full-Race ramhorn
Lots of fuel pump (SOS surge w/twin 320 pumps, 8an feed)
FID 1200cc injectors
74mm throttle body with port matched OEM intake
URGE built turbo head



Scott-

 

You have a 24% correction factor tho...so its not a legit 600whp, but your torque is dropping at 7200rpm...prob needs some timing ramped back in.

 

Yea, I'm in CO and dyno is at 6000 feet above sea level. Uncorrected was 485

 

the efr8374 did not fit the ptuning kit, but i'm sure the next-step smaller EFR would.
