370z 7AT problems with GReddy TwinTurbo tune - what to do?

octet

Hi guys,

I've recently fitted a GReddy Twin Turbo kit on my Nissan 370z RHD 7AT. After running into to so many problems with the car being a RHD and the steering rack interfering with the turbos, managed to overcome all problems and took the car for tuning at a respectable tuner here in UK.

Mods fitted on the car:

- Stillen Gearbook Oil cooler
- GReddy Twin Turbo kit
- GReddy ProFec Electronic Boost Controller
- Walbro 485 Fuel Pump
- Interior Dynamic 1000cc injectors
- CJM Stage 1 Fuel Return System
- CJM custom red anodised Fuel Rails

The tuner tried to tune it UpRev, but he's saying the gearbox can't handle so much torque the TT kit is making, therefore it just blows through the clutches. Apparently the clutches are slipping.

Now, to sort this out I would normally have these options:

1. Try and get the valve body upgraded by GTM (wonder if there is any slight chance Sam could do this without wasting my time and money, we all know GTM...)

2. Convert to a 6MT gearbox, get uprated clutch etc

3. Remove the kit from the car, sell all parts and the car and then buy a GTR and be done with it, this being the last resort.

What do you guys have experienced with 7AT cars and TT kits in US?

Also, has anyone here managed to convert to 6MT properly and everything works including SynchroRev?

Any other bit of advice is more than welcome, thanks a lot for your time.

P.S.
