turbo frs/brz or 2015 wrx/sti??? - Page 8 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I think you should give @ModBargains a call. They do Full Blown installs if I'm not mistaken. If you're having a shop install for you I suggest you ask them about cooling, clutch and gauges for your type of usage. They should be able to point you in the right direction.

Forums too - do lots of research.

I loved both cars but I just didn't feel right while I was driving. It may sound odd but I felt a little high lol. So with that being said I took ur guys advice (appreciate it) and test drove the vehicles and decided I'm going wit a turbo twin

I'm going with fbm 7psi tune just to be on the safe side for now

congrats! you'll love it.

Not for a long time.

How so? A clutch is either holding or it's not.

Wouldnt the stock clutch slip after a certain amount of power? And IDK if 7psi is high enough for one to need a clutch upgrade.

go with the fbm oil cooler and radiator + fans, as long as you bought the stage 1 turbo setup it shouldn't have any fitment issues.

Precisely. If its holding, then it's not wearing., so it won't last any less longer.

Stock clutch will let go at ~220-230 wtq (dynojet). We found this out during our tuning process where torque was incrementally coming up each revision and finally started slipping at this torque level.

It isn't a question of PSI, it is a question of torque. A good tune on 7 PSI will result in clutch slip very soon after it is installed.

SPCorBUST · 06-26-2014, 09:03 PM

depends on how you're shifting as well. as they're saying, psi doesn't matter - I was at 15 and it was holding fine except for WOT shifts where the rev was being held when shifting. max torque was 252, hp was 330 on the corn, which is all I really run.
