370z 7AT - Need Suggestions/Advice

Leroydsouza · 01-21-2015, 07:12 AM

Hello everyone

Recently (2 Months) purchased a 370z 7AT 2014 New from Local dealer (Dubai) GT Edition - Courtesy of CarbonSignal
Should have not rushed and bought an Automatic but they did not have the manual and it would take 2 months. No Way. Was picking it up from the showroom the very next day

Mods Currently are

1) Akrapovic Evolution
2) Motordyne ART Pipes ( On the way being Shipped)
3) Swift Springs
4) H&R 20mm Front & 25mm Rear Spacers
5) Motordyne M370

Coming to the advice/suggestions part,

I know what i want to achieve from this car (atleast 500 WHP) with reliability.
My knowledge about this stuff is umm still building so excuse my 'noobishness'

Yes i have done the search and been reading forever, But its time to plan out my remaining mods and i prefer a more direct approach.

1- Twin turbo or Supercharger ? Considering my location and transmission, Will TT hold up ? i lean towards TT because it seems to have a lot of potential . Stillens Supercharger may be great but its results dont seem to be satisfactory to me.

2- Will Valve body upgrade do the trick to support the FI route i go ? Or do i have to rebuild the transmission ? i honestly dont want to ship my entire transmission to and from someone in the US. And i dont trust anyone locally enough to do this job.

3- Transmission cooler and Oil cooler are on my list and probably will be shipped soon. Any other supporting mods ?

500 whp and DD reliability. Thats the goal. Time of completion and Spending a little extra for reliability not really an issue since i am not in a hurry.
Please bear in mind my shipping costs

it hurts when i pay as much for the shipping as the product being shipped.

Thanks in advance for reading and providing any suggestions etc
I pretty much wanted a Z for 5 years but only just recently purchased it. Done my reading, Done my research, But i would like to get some direct answers now

*****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

Definently something with a beefy torque converter, personally I like the auto/turbo combo.

Going to post this as I just saw this, this is for anyone, but OP this might be ideal for you.

For Sale ; part out of Major to odds item.
Megan370z has a slightly used 7AT for 2,000USD and is will to ship. This might be ideal to get this, ship it to level10 for a build and then ship to you once your TT kit arrives and install it all together.

This will give you a built 7AT along with your factory 7AT as a back up if necessary or if you ever part out.

level10's website lists 'no core' tranny upgrade at only a $1000 more than sending yours to them. So it would be cheaper to just buy theirs instead of providing a core.

I have spoken to level 10 and they quoted me for the transmission upgrade.

I have pretty much put my umm build list in stages,
once the ART pipes are here and i get an uprev tune, That there would be stage 1.
stage 2 - all supporting mods including the transmission
and finally stage 3

I do need the money for all this, So it might be slow but i want to do it right. Might invest in some "Show" stuff but dont really care much for it
Shes already a freaking looker

ok Noob question time - forgive me for this but i have to ask, Can i like ship all the 'parts' for the transmission upgrade and somehow build it here ?
i am looking for ways to avoid paying a bomb on shipping. Is this possible ?

AAM was in my list of possible TT setups

DO i need both valve body upgrade and Transmission Upgrade
(I have no clue wtf is valve body upgrade lol) but i would get it if i need it lol

I guess this year will only be supporting mods and maybe play around with appearance. Gotta get the 10-13k for TT by beginning of next year lol

Definitely getting the Level 10 Transmission upgrade. Lol but i would probably be paying 6k When it lands here haha. OUCH

theDreamer · 01-21-2015, 10:00 AM

A suggestion, I know you just bought the ART pipes, but look at what upgrades you are getting & what will carry over once you go TT.
The uprev tune will have to be re-done with the TT kit, completely, so might not be worth paying twice for that. The car with just ART pipes (and exhaust) should be fine without a tune.

also with going with TT kit if you want more power then the least restrictive exhaust is a helping factor. so when choosing your exhaust keep that in mind as well.

most people will run straight 3" down pipes for better flow.

JWillis72 · 01-21-2015, 10:02 AM

Level 10 will sell the parts to you so you can do it locally.

From a curiosity side, is this something a person can DIY with the right tools & time. Or even with the parts from level10 you need a good knowledge of transmissions?

Did not think of that.
Well The Akropovic has a big *** box thingy muffler at the rear, Guess i would have to change that !!
The ART pipes would be an issue ? they looked so pretty i just bought them.
And our terrible stock exhaust was not really helping.

So you recommend not doing a tune yet ?
My motordyne Manifold which i got excited for lol proved pointless because i do not feel anything. I assume i would feel something if i did a tune.
I am looking to get boosted only by the end of this year. Loads of work till then. Atleast i would have a 'faster' z

Btw thanks for all your suggestions, Its helping already

with a manifold and exhaust you may be on the boarder of needing a tune but then that's around $600 you'll be spending. do you have intakes as well? if so then it may be time for a tune so you don't hurt anything.

if it was me going boost I would just have 3" straight pipes. turbos are natural mufflers in the system.........and I like my car sounding mean and raw. hence why I have straight pipes even without boost lol
