i've heard that the CVT Extroid 8speed tranny's are quite temperamental if not serviced properly and i'm not planning on twin-turboing my 350GT sedan any time soon :P

I'm just curious to see if anyone has heard of someone who's pumped a considerable amount of power from their V35 or other car equipped with the same transmission...if so how much and for how long?

oh and why does 1st gear in my 350GT go up to 80km/h???

i had a mate get in with me the other day and showed him how the car goes and he was like "WHOA DUDE IF 1ST GEAR GOES UP TO 80KM/H...WHAT DOES 8TH GO TO?!?!!!"

just thought that'd make some ppl laugh....i was pissing myself while trying to explain the car doesn't do 500+km/h :rofl2:

...but seriously has anyone pushed lots of power using this transmission or seen someone do it?

Yeah i think you'll find nobodys been game enough over this ways to try anything big with them. Im sure it will handle bolt ons like exhaust, spacer and all the other stuff that doesnt make much difference. Iv seen plenty of japanese ones with the usual mods.

Its funny how we now have about a million pages on here of people claiming their auntys sister had one and it blew up (i honestly think its idiots getting fleeced by dodgy dealers and mechanics if anything). Yet only one first hand case that iv seen.... was on the vq30det powered gloria that was on here (which i assume was boosted up). But no actual proof of what may have caused the damage so nobody really knows what they might take yet you can assume just by the way they work that your pushing shit up hill doing anything outrageous to them.

Id love to get my hands on a gloria and just boost the shit out of it to see what happens but they arent cheap enough for that carry on yet.

It would be nice to be able to reprogram the gear ratios. Imagine that... that would keep me happy for ages just playing around with that.

The glorias with the exact same box had six "gears".

And im pretty sure the later model gt-8's around 2004 up got like a 4.1 lsd or something like that so they would be alot different to drive if the gearbox and ratios are all the same as the old 3.6

We need somebody with some brains to get into these ecu's and make them openecu like the evo's/sti's

hey oh yeah being able to reprogram the gear ratios would open up a huge can worms and that would be awesome!!!

    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
    • street use or race track, what hose size and why? what factors change with the hose size options ?   see most comon is an10. when you see most oem external coolers are closer to an12? does high volume oil pump like nitto need an12 or 10 be just fine
