thinking of a turbo setup
 

Hi guys Im new to the Forums and have been taking alot of time researching about a turbo setup for my car. I decided to give GTM a call to get more info on the setup and the supporting mods i need. So to my amaze i was told that i really didnt need anything done to the car but a better exhaust then the stock.
I was told that i could keep my stock clutch and flywheel because they have tested it on a car making well over 580whp and it held up for about 20,000 miles. When the subject of gas mileage came up i was dumb founded that the turbno setup will not only give me ungodly power but that i would have great or better gas mileage on the car then stock. Im sorry for all my ranting but i thought this would be great info to post up for anyone else looking into to doing a turbo setup. GTM has great phone support and will hold your hand to make sure that every question is answered and that your confident on your decisions.

I have the GTM stage 1 twin turbo. I am running with the stock clutch and have about 7000 miles since install. As long as you aren't launching the car real hard on drag slicks then the stock clutch will hold fine.

My only supporting mods are a 34 row oil cooler, exhaust, boost gauge and AFR gauge. The kit comes with everything else.

As far as gas mileage. Not a chance to get better mileage. While the car is probably capable of getting near stock mileage there is no way you will want to drive it that way. It's way too much fun to hear the turbos spool up and that takes extra gas. I was getting about 22 mpg average per tank before the TT. I get about 18 mpg now. 4 mpg loss is a good trade for an extra 200 hp.

Dembflyr, did you hook your exhaust back up? Or are you still waking the neighbors with the open exhaust? lol

Open down pipes. They can sleep when theyre dead. :D

I haven't been driving it much really. And I wait until at least 10:30 before I start it.... Except for this morning. I'm leaving in about 30 minute for my tire install.

Awesome! :tup:

I would love to hear your car when you really get on the throttle! I'm betting the fillings would fall out of my teeth and my ears would bleed! :rofl2:

We have an absolute amazing deal on a Twin Turbo kit right now. http://www.the370z.com/aam-competiti...o-package.html

You should search even more.. Complete your due-diligence before committing..
And do not follow the crowd blindly. Educate yourself now, so that it saves you $ down the road..
FYI- YOU WILL NOT GET BETTER MILEAGE.. ( if you really believe this, you need to research even further)

I would highly recommend you waiting to see what Boosted Performance has in store for the 370z platform.

edit: ^^ didn't see you had already mentioned BP ;)

OP, there are a few single turbo kits popping up that look promising. you may want to look at those as well. off the top of my head, Boosted Performance (in development), S&R (in development), and STS make ST kits

Please tell me there is a thread somewhere on this! I wanted to buy his kit for the 350 so bad but then it got totaled out. Super good guy from what I have read on the 350z forums and cant wait to see what he has in store for the 370z.

that's exactly what happened to me! he's developing the kit now...

I would wait a few months for the fast intentions twin turbo kit, just so you can see whats all out there before you make your decision! Good luck going forced induction! I cant wait for my build to be done.

That is awesome! For anyone wanting to go FI I would wait because the Boosted Performance kit will definitely be a great option.

Give you guys a teaser:

A true twin scroll with equal length primaries, utilizing the firing order of the VQ. Nothing like this out there. This will also allow for big power because it will be a true T4 with options up to 1.32 a/r.

Will be using the all new Precision 6266 and 6766 T4 CEA billet turbos.

I will be a sponsor here shortly.

What do u mean a "true t4"? does the turbo housing bolt pattern make a big difference?

or am i thinking of the wrong t4?

T4 vs hybrid t3/t4 turbos.

Anything smaller than a T4 is a waste of time as it will just choke the engine.

Holy crazy piping scheme, batman. Looking forward to seeing results. Please start a new thread for your kit so we can follow its development. Love the twin scroll design. On STis, you could pick up several hundred rpms in spool using twin scroll. Will be interested to see if in your design it offsets the loss in spool from moving the turbos away from the block.

I will start a thread in about a week or so.

Also, this will be the quickest spooling single, because nothing out there is closer to the headers than this. The top mounts are much further, and the STS is..well, in the back of the car.

This will compare very well to a TT kit, because the pulses are kept seperate.

<3 on your kit. I will be buying one when ever they go into production.

Would be interesting if you would do a twin turbo mid mount setup too. :tup:

Wow. The welds look great and looks you all have got a good idea going can't wait to see those numbers

i will tell u my numbers soon ;)

i take it you've got the donor 370?

Fast Intentions is having there TT kit coming out soon. That kit is something to wait for.

Yes, should arrive some time next week, with a FI exhasut system. I will have two downpipes made, one for those that have a FI exhaust system and one for the OEM system, where the down pipe will connect just before the exhaust splits in two.

Will have a full build thread soon.

This looks great my STS starts boosting at 3600 and in full boost by like 4200 that'd be awesome if you could be full boost at 3600

I think STS uses a small T3 trubine, so it will spool quick and will limit your power due to flow restrictions. What is the a/r on that anyway?

I wanna say .57 and it's the ball bearing turbo as well I that means anything to you

to clarify no i am not his test mule as the "free turbo" car, that is someone else who is like batman and will remain unnamed i guess..

i will however help Sasha out in giving him access to a pro tuner we have both worked with before and his comments will help him out fixing anything with the kit.

I will also show everyone how simple this kit will be to install and give as much detail as i can to help Sasha out!

With that setup, when I buy your kit, I will run into problems lol. i think the nismo guys have it connected at a different spot.

It is more than likely a T4 .58 then, and that is very small and is the reason you are spooling that quick with a turbo that is that far from the engine.

R&D on my end (on the VQ) shows that you need a T4 .81 for about 600whp (DJ) on pump, and .96 a/r if you wish to push things past that. (.58 T4 = .7x T3)

I find it very funny when a manufacturer says "600hp" turbo. That is great, but it is only the rating of the compressor wheel, and not the turbine. So you have a large compressor that will flow 65lbs/min of air, but you have a turbine housing that can only flow 50lbs/min....and THAT limits you to about 500hp. So you can have a turbo (compressor) that is rated to 1000hp, but if the turbine stays the same, all you will get out of it is 500hp.

Fluid dynamics will never cheat you, but somebody selling something will.

is it april yet, i cant wait much longer!

TBH tho, for the minimal boost that most people run on these cars (anywhere from 7-10psi most of the time) a larger turbo isn't needed because 600whp is the danger zone for these engines. seems almost like a smaller turbo would serve a better purpose for the boost that we are running, no?

Or maybe its a .67 now that you mention it idk ,
They told me I coulda got the bigger turbine housing cause of my sea level but I just left it , looking forward to see what your kit does

I agree

This is true to a degree. Once people start building the engines, this becomes a problem. Now you have to use a large turbine for the added flow, but you will lose a lot of spool with a kit that places the turbo far from the engine. Also, these engines are not made to be torque monsters, so low RPM boost does not play a big role. This is a high revving V6 and it makes its power at 4500rpm+.

I will have 4 turbine options, so it will cover everything from a stock block to a fully built one.



No such thing, it must be a T4 .68 then.

i was originally planning on doing this same time next year, but i'm not sure i'll be able to wait either. can't wait to see your build log!

:iagree:

When will the kits be ready?!?!

Ours is ready right now and has been proven over the last 3 years around the world. ;)

I would love the get the Twin kit but my wife would be cutting off my twins :owned::eek:because of the price tag. Im look for the single turbo alternative due to price. Can a single turbo like an STS kit be able to have the same HP and proformance and a twin turbo kit?

Lol your opening a can of worms with This question
