first off, stay away from GTM!

they are out of business and ripped off many people here for thousands and thousands of dollars.

secondly if you go the turbo route you can still have a semi quiet exhaust. turbos act like giant mufflers.

unless you plan on building the trans( and there is no real solution yet) I'd stay away from a Turbo, the WTRQ will kill the trans. A SC is better as it will build WTRQ and throw it all at once at the trans. You wont make as much power but the tranny will hold, or at least longer, I ran my SC kit with 330 WHTQ and the trans was fine, Motor blew tho :( 457 WHP

..........no way of building the trans? you don't get out much do you? lol

level10 makes a built tranny that can handle over 700tq

also Tony at FI now make their own AT upgrades which paired with their TT kit set the 370Z 1/4 mile ET record.

just saying.

I have made some updates to the details, GTM is now listed as out of business & have added Fast Intentions & Level10 with what details I have uncovered. If anyone can get me more details (potentially email) on the Level10 370z transmission built, components used, cost, etc. and send it my way that would be very helpful. Fast Intentions has not officially released theirs yet but have given some details on what they are using but no pricing currently. Will add more details on both as they come in.

What I added:

My correspondence with Level 10 regarding the cost of their transmission upgrade

The BulletProof Transmission upgrade is rated to 750hp. Once upgraded all gears will be capable of performing under boost. The turnaround time is 3-5 business days. The Price for the bulletproof upgrade is $3995. This includes the transmission, ValveBody and Torque converter. Let me know if you have any other questions I’m always glad to help!

The price I quoted you is for the upgrade which uses the transmission currently in the car. The upgrade includes the Level 10 High energy internals, Super pump upgrade, BulletProof ValveBody and BulletProof Torque Converter upgrade. We do carry the Bulletproof Transmission in stock for 6596+$1000 Refundable core + Shipping this unit if for the coupe only we do not have one for the roadster .

Kojack, could you provide me with the following details, will add you to the FI boost thread along with this one noting you have a built 7AT.

Info to help people:
-Year
-Kit used
-Current HP/Torque
-Current PSI
-Fuel
-Miles since kit installed
-Other upgrades (clutch/flywheel/engine/etc.), also include miles when these upgrades were completed with done after original FI install

Updated the Level10 details to include this info.

I know level 10 makes one, Coop was running one is his( 5spd) tho, Is't there some on with a built trans from them a TT kit and trans has broke twice? I know level 10 is more than working with him on getting retuned and rebuilt but just saying there's issues there.

There's someone from the UK who did a thread on a Level 10 build recently.

http://www.the370z.com/engine-drivet...e-what-do.html

I forgot about his build, need to dig into the details.

Looks like:
-Level10 built transmission
-554HP & 465TQ
-Greddy TT kit
-Fuel stuff

Here's the one I was thinking about on the G Forum.

Help 7A/T Forced Induction Issues/Problems - MyG37

Looks like level10 is slowly fixing it, but it being an X & 7AT that throws a lot into the mix. Hopefully it was just the ECU & TCM not playing nice and with some tuning work it is resolved.

Sorry, I didn't clarify it too well, Cooper and myself have 5-speed auto built from Level 10. And I spoke with Pat regarding about you guys with 7-spd auto and he mention that he does them. Can't recall how much he quoted but knowing it was less then 7grands (compare to GTM's price) when you bring your transmission to them.

Hey like your tip on Level 10 transmissions - thanks- been thinking about going with a STILLEN S/C - is it really that necessary to do the tranny at the same time - Costly about 7k for complete Bullet plus the converter !!
