I am to blame for some of the delays with lack of instructions. I had to push Sam for time as my build had a definate end date that need to be reached.

So how is the car doing now after a few miles on it with the kit? Got good power when you stomp on it? Gas milage?

True guys! My build is also holding up a good bit of work as I have an approaching magazine cover Sam is putting a lot of focus to finish my build. Things will speed up so stay patient.

well as for it holding up over 5000 miles on it now and no issues still feels the same at foot to the mat as it did when i first got it. as for gas the wife has not seen mush of a differance with her milage. it seems to be around the same about 9L/100km

Delays suck, but at the same time, for the guy at home trying to do an install, i bet he/she will really appreciate someone spending the extra time needed to make sure the instructions and kit are 100% correct. Probably more important is that the easiest possible installation method is achieved. We really don't know the process used to finalize the instructions and kits. i'm guessing it will be closer to a factory service manual level, than the some of the black and white 6 picture crap you get with most aftermarket parts.

Shumby, I'm sorry I haven't been able to keep up to date. I remember hearing something along the lines of that you couldn't hold boost with the long tube headers. I figured it was because of a leak and they've since fixed. However, did finding and fixing the leak allow you to use the long tube headers? I honestly think GTM has greater hardware than Stillen but this issue with the long tubes is dissuading me. Lastly, is it because of the AT tranny that you don't want to go above 350 tq? Anyone have an idea how much the MT can handle? I hope it's above 400lb/tq.

Soon... (For the MT)

Who builds our MTs and is it specific to the 370Z? I know Tremec, which makes a number of transmissions for multiple manufs, has max torque ratings on the spec sheet of their website. Wondering if this info would be available somewhere on our transmission as well.

Our manual is manafactured by Aichi Kikai and is rated at Max 332LbFt.
(that doesn't say it can't take more then that, this is a rating for the total transmission assembly)

The transmission program is the MRA70 (ZG6) and also goes into:

Infiniti EX
Infiniti G
Mercedes-Benz Viano
Mercedes-Benz Vito
Nissan Frontier
Nissan Navara
Nissan Pathfinder
Nissan Skyline
Nissan Xterra

Allthough not all of the above are produced by Aichi Kikai...

(the automatic is made by Jatco and is rated at 295 LBFt)

Hope that helps...

Thanks for the info. Rep added.

If I'm reading this right then Nissan put more torque from factory on the AT than the manufacturer stated was its "max." I think the highest tq Z on the forums is Fusz I guess I'll ask him how it's holding up.

No, the manufacturer of the transmission rates it at 295lb-ft. The stock 370 puts out 270 lb-ft.

NYBladeZ · 07-21-2010, 03:33 PM

duh oh yeah my bad, I think it can handle way more but for liability reasons they probably underrated otherwise Nissan could argue that the transmissions don't meet the stated specs.

m4a1mustang · 07-21-2010, 03:38 PM

Well manufacturer torque specs generally err on the conservative side, but they're not too far off of the true max numbers.

All I know is the MT rated at 332lb-ft is seeing up to 400-415lb-ft in some of the FI applications we have seen so far, which will make for an interesting longevity study. Probably not the best idea to power-shift a TT car on a stock transmission. :P
