- valve body upgrade
- torque convertor upgrade
- internals - master overhaul kit - clutch packs

1000 bhp, 12.000miles or 12months warranty

That is some serious service! wow.

I like the sound of your exhaust, what is your setup?

Hi Charles,

Btw, thanks for sorting out my CJM fuel parts. Had a problem with the 370z Fuel Rails from you, the trumpets were not long enough to press the injectors in properly, only just cover the o-ring on the injectors. Any idea?

The box was delivered to Level Ten on the 30th of September and left yesterday 10th of October, so that's 7 working days (was ready on 9th October). Amazing fast service and brilliant customer service, Dave is absolutely phenomenal. I so much wish somebody like Level Ten, Coz @ CZP or yourself @ CJM would buy GTM and continue to manufacture their awesome products with proper customer service skills.

It's Amuse Titanium exhaust with MotorDyne Y pipe.

sub'd, the most interesting thread to pop in a long time. Waiting on what FI has going on since that would be a lot easier than shipping the whole trans across the country. Geeze, if FI, gets their kit CARB approved, I might have some tough decisions to make.

Great news! Gearbox made to UK just now and will be fitted tomorrow. :driving:

I will have to see a photo of whats going on. Send me an email when you have a chance. They are made to use injectors of the same body length as the stock injectors, which is about 48mm between the orings. Most the popular injectors are available in this dimension.

octet 10-17-2014 05:43 AM

They are the ID 1000cc, so I guess fitment shouldn't be a problem. Let me try and dig for some photos, if not, will try and get some tomorrow when I'm fitting the gearbox.

I cant really tell what the arrows are indicating. I noticed you didnt use the included countsunk bolts.

ID 1000 are the same injectors I have. It will definitely all fit up. You want to use the supplied bolts though.

phunk 10-17-2014 06:10 AM

It will fit up like this. This is with stock injectors in the photo, but ID1000 are the same dimensions.

octet 10-17-2014 06:10 AM

Did not get any bolts with the rails :(

phunk 10-17-2014 06:12 AM

Oh I can see whats wrong... You are trying to make the crossover hose go perfectly straight across. Its not made to go that way, its supposed to be tightened after the rails are bolted down, and it will have a curve.

attached is a photo of it installed on my car, after rebuilding the injector harness to eliminate the wiring crossover in the front.

all the rails come with bolts... but i think your setup was shipped to you through a dealer and perhaps they changed around the packaging to forward things to you there and missed the bolts.

attached are the bolt specs, you can probably find them locally for 1/10 the price of shipping 4 of them all that way. However, if you cannot, we will have to send you some!

What you really need to know is that they are M8x1.25 Thread, 25mm Long, counter-sunk, 90 degree taper (i believe the typical taper for metric countersunk).

octet 10-17-2014 06:24 AM

The crossover hose is fine, I guess it's just the bolts I'm missing, although the rails were flush with the OEM bolts. Any chance you could mail me these 4 bolts in a padded envelope please?

octet 10-17-2014 06:25 AM

Yes, you shipped to Coz @ ConceptZPerformance :)

OK, I'll try to source them in UK first. Thanks a lot!

phunk 10-17-2014 06:36 AM

email me your address to sales@cj-motorsports.com and I will see what it says for shipping the bolts there.

The OEM bolts will in theory work. However, I am not sure if the rear right hand bolt will clear the intake manifold if you tried to put it on... since its raised up much higher on thick billet rail versus the sheetmetal factory one.

octet 10-17-2014 03:46 PM

Just went to check the gearbox tonight before fitting it on the car tomorrow, I'm impressed, they even cleaned the outside and resprayed it, including the valvebody and torque converter!!! Top service!!

octet 10-18-2014 12:14 PM

IT'S ON!!!

Still in the garage, just need to sort out the engine mounts spacers and we're good to test drive it, shouldn't be long now.

octet 10-18-2014 07:30 PM

Right, it's official, the car is: INSANE! It's the DEVIL itself!!!

DEpointfive0 10-18-2014 07:34 PM

Dumb question, did they include a heavy duty flex plate?

phunk 10-18-2014 09:24 PM

Post in-car video ASAP!

This could be one of the coolest things to come to the 370z.

ZeN 10-18-2014 11:09 PM

I'm jealous, please please post video of the speedo with tip in throttle gear change at low speed, high speed change, and abrupt downshift from highspeed while braking hard. I'm thinking of ordering all parts same as yours if its true that it can handle 1000 bhp.

No, OEM one used.

They are helpful to see how much power you are putting down... I suppose you will see an improvement in your laptimes too.

Thanks for posting the YouTube video so quick.

octet 10-19-2014 10:39 AM

Car will go on the dyno soon for UpRev tuning, will post dyno chart here

KN21283 10-19-2014 12:34 PM

Can you gives us any details on how the built gearbox shifts?

octet 10-19-2014 12:49 PM

The car is still running on a base map, so can't test it properly being limited to 4500rpm, but it just feels like factory in terms of driveability, no jerkiness while switching gears. No more lag as in the OEM one, but there is tuning to be done in the line pressure and torque table, so will report back once the car is tuned.

Sounds good already. I only went with a valve body upgrade after hearing of the garbage stage 4 trans gtm put out. Thinking there was no hope for the 7at. Hope everything goes good.:tup:

Z eliminator 10-20-2014 06:53 PM

I have a stage 4 GTM.
It works great.
Shifts way quicker than a stock unit.
the improvement in the 4th to 5th shift time is a big improvement .
But remember its built for a 650 hp motor. and tuned for one.
It may not work on a stock engine,

EZT 11-09-2014 12:40 PM

Level 10 really came through for you, jotting them down for my future buy list after TT.

ZeN 11-15-2014 06:03 AM

Update? Does it hold the torque? Engagement like oem or bang like hammer on each shift? Anymore rpm flare esp 2 to 3 and 4 to 5. Can you full throttle 5 now without worry?

Legz 11-15-2014 11:12 PM

Did you have to do a custom ecu flash to get the new tranny paired up?
