Howdy,

Just had my R32 w series II RB25 tuned by Dr Drift.

Mods as follows:

- Nistune & Z32 ECU

- 3'" Exhaust

- Blitz turnflow FMIC

- Pod

- HKS 2530

- Yellow Jacket Coil Packs

- Boost T

- Z32 AFM

Car makes full boost by about ~2,700 RPM and pulls like a train!

Made 218 rwkw on a very conservative tune and only 14 pound

The Doctor does very good work!

Cheers,

RPM in graph is about 5% too low - full boost at 3500rpm.

3 tunes at increasing boost - still not maxed out (but not too much left, maybe 1psi).

      Hey Kaz, Unfortunately I am not at home currently and wont be for a few more months so I do not have access to my files or CAD. And at this point I prefer to keep the files to myself as I want to potentially make a few more pairs and see if they will sell within the EU before openly marketing them. But the way it's shaped and how small it is, I don't think you can fit both an indicator and a fog light onto the same surround, unless they were very small LED-type clusters.

      Replacement clutch recommendation for an R32 GTR

      By Ryno · Posted

      I’ve just installed a Uniclutch sport into my R32. I’ve been blown away by it… it drives like a stock Toyota Corolla. It doesn’t make sense to me that a performance clutch can drive this well. I was about to pull the trigger on a Nismo Coppermix twin plate when I discovered the Uniclutch and decided to give that a shot instead. They’ve changed the game and I couldn’t be happier.    I was previously using an Extreme cushioned button clutch with lightened flywheel. I’m still using the same lightened flywheel with the Uniclutch.
