  1. Hi there. Which will be better for street forged RB26? Botch turbo's are for 750[crank]hp - my power goal is 650-700hp on 93octane. GTX3076R will have 0.83 T3 twinscroll and GTX3576R probably 0.61 T3 twinscroll. I hear GTX3576R spool better than -5. I need the fastest possible spool for that power level. Even i prefer 650hp over much lagged 700. It's true GTX gen 2 spool faster than gen 1? BTW how realistic is G25-660 with 650hp @ RB26?
  2. Hi there Any one try to set the valve clearences tighter than IN .42 EX .35? It should improve the preformance? I have stock head with HKS 264 8.7 cams and forged engine.
  3. Much better spool and response against stock 2.6?
  4. Spool have billet full counter weighted crank 😀 I think i also go with Spool
  5. Hi. I'm going to rebuild my RB26. Which of that stroker kit is better? Tomei cost 4200$, Spool 3900$, 50ccm3 difference, Spool have billett crankshaft. Power goal 650whp, street car.
  6. Great information, what about spool ? U can post some dyno's
  7. Hi there 😊 Anyone have experience with Garrett GTW turbo's? I'm going to buy GTW3684R with 0.70 T4 divided exhaust side. Hope it will spool like GT3582R with 0.84 T4 divided and make at least 50 horsepower more?
  8. That's nice hint 😂 Actually engine build power till 8200, 8500 is safe without upgraded valve springs and retainers?
  9. Hi there! I have GTX35 + CP Pistons + Bridgeway H-Beam rods + Nitto oil pump + HKS 264 8.7mm + Cometic 1.3mm head gasket + ARP head + rods stud + Harmonic balancer Ross Tuffbond. Head is stock just that cams. What is the highest safe revlimit on that setup for street car?
  10. What's the safe boost level for 8374 and 2.6 capacity till 8200? I don't have speed sensor
  11. I get it I have 8375 .92 T4 divided in my forged Rb26 and HKS 264 cams on fuel pump ,and it's a bit laggy i running 21psi it's street fast car but it push hard after 4300. My power goal with ~2.6l capacity is 420rwkw on fuel pump 98 till 8200 rpms, 8374 with hotside .92 is the best way for fast daily car with 420rwkw? The little problem is that hotside is huge and i have little space One page ago i read 7670 is for max 375rwkw, with 1.05 hot side also? But also it's information the compressor is for 640hp so maybe with 1.05 it can make that close 400rwkw in 2.6l?
  12. Guys short question: will EFR 8374 .92 spool faster than 8375 .92?
