  1. Mechanics in Socal

    JSR Engines in Covina Call ahead they are very busy but can make room if they know you're coming in.
  2. Do I need to upgrade my intank fuel pump?

    For sure- I trust Jake and his son 100% - they live and breathe FK8s and test on their personal FK8 before releasing anything. Their work has always been top notch and I'm lucky they are in SoCal. 20+ years in the Honda game and stands behind his work. Ethanol = torque monster 😆
  3. Head has left the chat

    No need to test - you'll make more power everywhere with motec - youll be able to run more boost and dial in the VE properly There are work arounds for hondata but ultimately your stuck around 32psi or so vs going much higher on motec (if the turbo can hold the rpm) depending on turbo size...
  4. Head has left the chat

    I gained 70whp in the lower areas and around 50whp with a ported head on stock cams. Same everything else Ported head allows you to run more ignition timing on good fuel- makes more power everywhere. The trick is having a proven port job done by someone experienced. Not too many folks...
  5. Do I have to upgrade head studs and head gasket?

    That vid description has my full mod list If I were to do it again I would probably coat the downpipe and front pipe for heat and run an RV6 front pipe vs a PRL For peace of mind and ease of power the head work is a must. It just makes so much more power everywhere and allows the turbo to...
  6. Do I have to upgrade head studs and head gasket?

    Reliability wise I've had good luck so I would say to me, they are similar. The difference is the standard g25-660 hotside is a .72 IIRC while the hotside on the R660 is 0.82 - this means the Garrett will spool a touch faster but get choked up before the R660. In order to make the peak power...
  7. Do I need to upgrade my intank fuel pump?

    I remote tuned with FK8td multiple times- the dyno helps dial things in quickly vs waiting weeks for email tunes. Now I same day tune with JSR as they have an in-house dyno and do all my installs I'm sure all the remote tuners can tune you if you have say 4 ot 5 hours set up - the flashes...
  8. Do I have to upgrade head studs and head gasket?

    MHI is too small R660 is good for stock engine G30-770 is ideal for me and will be what I move to when I build the bottom end and shoot for more. The R660 is basically a G25-660 you can bolt-on to stuff you already have. The Garrett turbos are great and if you want 600+whp are the way to...
  9. Do I have to upgrade head studs and head gasket?

    To upgrade the valvetrain you'll be taking the head off - much safer/easier While the head is off the head port is a no brainer - should be around 1100 to have it ported by JSR and an easy 50 to 70whp gain across the board even on stock cams. With the TR2s you'll see even more gains...
  10. Do I need to upgrade my intank fuel pump?

    1400s are ok - they just run out around 560whp or so as you Rev the motor past 7200 Once I switched to the 2000s I was able to carry power to redline - I still have some room left at 600 and with the upgraded low pressure side should be good for 750ish on these injectors. The 1400s have a...
  11. RE-71RS or Cup 2 Connect for weekend only LE

    The softer compounds just pickup/fling more rocks - you can run mud guards to reduce kickup or apply some ppf to the side where they hit to be safe.
  12. k20c1 and fk8 drivetrain swap into 2020 fk7 cvt

    There are guys doing k20c4 swaps and I think their cost is around 10 to 15k+ A k20c1 swap would be more as it uses a different fuel strategy vs a L15b7/k20c4 Would be better to just buy a used Type R but I'm sure most guys looking to swap don't want to hear that. Best of luck
  13. Do I need to upgrade my intank fuel pump?

    1000+ miles a month on e50 You can ask Jake about the walbro - most guys run the dw300c and then upgrade to the hellcat setup to eliminate the headache of the oem fuel filter/tiny pumps. I need to change my filter again so I'll probably stop by and get that done soon. Oil change and maybe...
  14. RE-71RS or Cup 2 Connect for weekend only LE

    The Cup2 has more feedback than the RE71RS - both have immense grip but when pushed to the edge I felt more communication from the Cup2s - still would buy either one as they last about the same for me - typically 3 to 5k miles before I replace the fronts and about 8 to 10k in the rear depending...
  15. Should i buy a CTR that has been to 2 accidents? I have detailed Reports of each

    He'll no - way too many clean Type Rs to consider this. Accidents mess up stuff you can't see - forever changing the car. I would never buy a wrecked car as I'm not concerned about the appearance - I'm more concerned on internal damage to the body in white.
  16. Do I need to upgrade my intank fuel pump?

    All the JSR stuff is tested and proven to 715whp on stock bottom end. The hp line is in its 3rd revision and you can buy a spare already done from them or send in one to get the work done. On stock fuel system it allowed me to go over 400whp without any pressure spikes/weird fueling issues...
  17. RV6 R660 RED Ball Bearing Turbocharger

    They are on the smaller td04 sized center cartridges so they are very similar with smaller Kuro probably being slightly quicker but when your making over 400ftlbs of torque- lightning fast spool down low = wheelspin. I hated stock turbo on ethanol as 409/434 came on instantly and you have to...
  18. RV6 R660 RED Ball Bearing Turbocharger

    R660 spools very fast - if you want something that makes less power and spools like stock the Kuro is out there. The R660 is easy to drive and spools like a g25-660 - very quick. Stock spool is annoying and overloads tires mid corner on small throttle corrections.
  19. RV6 R660 RED Ball Bearing Turbocharger

    RV6 R660 is capable of over 600whp already - the new one should probably hit high 600s-low 700s if they size it like a g30-770
  20. Do I need to upgrade my intank fuel pump?

    Yes - the low pressure pump is the only thing feeding your hpfp and injectors You'll be commanding a massive fuel demand on full boost threshold and smaller lpfps cant keep up as well. Did you upgrade the high pressure fuel line? That's a major restriction at 400whp and if you have goals...
