| I am looking at having to rebuild the HKS 2835s which are spec as below and been thinking of moving up to the GTX line. Seems that the GTX2971R are about in line with what I had before but the GTX2867r2 is looking interesting. A couple changes will most likely happen
1. FMIC will go away for side mounts with new 2.5" piping
2. E85 + new rails and injectors ID1200 or larger.
3. Haltech PnP Pro + new engine harness from Wiring specialities
4. Re-Enable VTC see if I can get the Tomei solid lift cams to actually flow else replace with the JWT 500 cams
5. New fuel Pumps + new filters maybe -10 feed vs the -8 I have now.
6. A few BDE items .. BDE I will contact you about what I need (like everything).
7. I will ask more about this but I am considering replacing the compression ratio as the motor is going to get freshened up maybe going to 9:1 or 9.5:1 ... COMPRESSOR:
-Wheel- 52 Trim -51.2 inducers / 71.1 Major
-Housing- 70 Inlet / 50 Outlet - 0.50 A/R
TURBINE:
-Wheel- 84 Trim - 56.5 Major / 51.8 Exducer
-Housing- GT25 inlet / Outlet spec:
External GT30; 0.61 (will probably go to .73)
So the questions are whats the dyno numbers for the GTX2867R on pump gas, on E85, Q16? Has anyone seen anything for the GTX2971R? I know for me its hard to compare to other vehicles as few people have external wastegates and pentroof manifolds but I like to gauge a little on what direction to go now.
Thanks in advance
