  1. yes I agree, try the adaptor. here is a similar fitment photos that somebody sent to me
  2. most of our twin turbo customers go with the 6258s or 6758s. but we have a few guys in the US, Europe and Japan with twin 7163. the setup is another level completely... there were some twin 7163 graphs from twinsturbo recently. i think i posted it in the other thread as well, completely mental combination
  3. thanks. i get tired of posting this ^^^ in response to "what does it trap" posts. Believe me guys, i get it - you want to compare it to every other turbo out there. The thing is, these are different. And the difference is not on a dyno or a drag strip. If you actually get real experience with an EFR then you will get it too.. and if drag racing is your thing, Twin-EFR is the way. Not single. good guys at nizpro
  4. my car is 2.6L and circuit only - I rarely drive on the street unless driving to the track. 4500rpm spool is late for the small track. 9180 gives violent acceleration.. with a nose heavy RB26 up front, i felt it was too much turbo for this stock displacement on tight tracks. I prefer spool by 3800-4000rpm so the 8374 was perfect for that. I expect 9174 to bridge the gap and will try that next. 2.8L might be the solution in the end. also the 9174 has the alloy CHRA and saves 7lbs so thats a bonus!
  5. I ran the 9180 IWG on my 2.6L rb26 for a bit. It was on full song by 4500 like chris said - but that's a tiny bit laggy for my preference. It made 750whp and broke my R33 trans 4th gear. Then I installed an R34 6speed trans and really began to appreciate the turbo. Now that i am putting the car back together i will probably go to a 9174 IWG next
  6. BorgWarner makes 12.5 million turbos per year. Garrett makes 14 million turbos per year. Precision is not "main competition" for either... outside of car racing forums. their infrastructure, engineering staff and resulting turbo quality arent even remotely close to being on the same level no changes to the 8374. same turbo since the initial release in 2010 BW issues comp maps for all of their turbos, as well as providing max turbo speeds and corresponding max airflow rates. They also perform burst containment which can save lives... but I agree with the matchbot app. Incredibly useful once you understand how to navigate it. It takes me 5 minutes to make an OEM quality match now
  7. BW updated the wheel aero on the SXE turbos. the 8375 is their older turbo with 75.99mm turbine and 270 thrust. (probably should have called it 8376 all along) -- SXE 8376 is their new version of this turbo and is now 76.2mm with 360 thrust and EFR blade aero (with corresponding bump in turbine efficiency). Using the same housing A/R an SXE can spool a little earlier due to the turbine aero - but the more aggressive compressor wheel makes the turbos spool almost identically. Attached is a photo of the old turbine wheel on left, new SXE on right. We have these in stock at a healthy discount right now if you need one
  8. mr skidz, your posts are coming off as trolling at this point. do EFR people go into precision threads and talk about how great their mates setup is, but wont give any details?? whilst complaining there is no data? cmon... my recommendation for any EFR setups targetting big power and early spool -- twin EFR7163 is untouchable. Below shows E85, 3.4 liter 2J. 145K shaft speed, 41 psi… 1185 wheel and 930-980 tq spinning 25-30 mph difference between ft and rear wheel speeds.. She has all of 1200 wheel and 1000 tq in her…
  9. the inconel (airwerks or garret or precision) will fracture more slowly than gamma ti (EFR). this is why borgwarner tells customers drag racing: buy the airwerks OR twin EFRs. below photo shows a gt30R turbine wheel subjected to overspeed from owen in the UK
  10. we have the 4port solenoids in stock if you can not find them locally http://www.full-race.com/store/efr-turbo-accessories/full-race-4-port-boost-control-solenoid-1.html
  11. VFregal - which turbosmart IWG spring and how much preload are you using? More than likely you need more springs in the IWG actuator..
  12. excellent result kaboobie. That powerband is great for pump gas and cats -- which cats are you using?
  13. hi matt, you can purchase directly from our website or you can call our office. Im not sure who to recommend for install in victoria. I will ask a few contacts. feel free to email me directly at [email protected] with any other questions
  14. the high boost canister is sprung fairly conservatively - i typically like to run 6-7 turns of preload on it. Or a turbosmart 26psi IWG with 4mm preload
  15. i was a fan of GT4088R back in 2003, it was a good twinscroll turbo at that time. Now its 2016, GT4088R is outdated and very old design. EFR9180 murders it. Even the journal bearing SXE turbo smokes the 4088R I suggest to check your IWG spring and perform a boost leak test. For an EFR8374 on RB26, boost should be well on around 3500rpm. 4000rpm is a little bit late We have a couple R32 GTR in our shop right now if you need photos of anything in particular. ^^that is correct
