370z 7AT - Need Suggestions/Advice

JWillis72

*****Fast Intentions "Twin Turbo Kit" is here*****

See the end of this post, they are the only ones working on a TT for the 7AT that I know of.

You are definitely wanting to go with TT. I don't think either of the single turbo kits fit an AT and none of the available SC options are going to reach your power goals.

Fast Intentions TT kit and AAM should be good options. My personal opinion is the FI TT kit is a better kit but there is nothing wrong with the AAM kit. Here's a link to AAM building a TT 370Z AT.

AAM Competition - Nissan GT-R, 370Z Turbo Performance Specialists

The critical part is getting an upgraded AT to handle the power level you are shooting for. Fast Intentions is working on one and there is another company that has one on the market. As soon as I find the link I'll edit this post.

Edit - Upgraded AT

level10 out of NJ.

its like 3200 for a 1000hp tranny and that's sending them yours to upgrade.

think its 4200 for a 100% new tranny sent to you.

1) Twin Turbo will be the only option to reach your power goals, the Stillen SC will fall around 450whp
2) There are guys running 500whp with just a valve body upgrade, but it really comes down to being a ticking time bomb with that. I am sure it can last, but the harder you push it the weaker it will get.
3) Other supporting mods for just the tranny will be a good tune that will adjust the transmission pressure lines to help hold the power.

Now back to point 2, the main weak point in the transmission so far seems to be going into boost in gears 5,6,7 as they are the weakest. Though a hard launch in 1 will definitely cause some major wear, but it seems the higher gears are not able to handle the TQ levels of any boost application (TT/T/SC). The transmission is only rated for about 295lb of TQ so adding boost you are adding easily 100lb more.

I know you have been reading, but in case you missed this thread it is full of info for the transmission & boost: Forced Induction & 7AT 370z Info

they aren't even listing our 7AT in their option which is RE7R01A
keep in mind a brand new 7AT is 8k$

an 5spd from a 350z which is RE5R05A can be bought brand new at 2600-3000$

there's 2 guys on here who have got their tranny for the 370. you just call and tell them and they make it. i think the listing is general.

the one guy is in England running it with a greddy kit and loves it.
