Gtm Twin Turbo Kit

[V(35)Powarh!]

Hey fellas any of you have or know of anyone who has ordered the gtm twin turbo kits from the u.s? Ive been doing alot of research and would love to hear of any stories you may have for me.. cheers p.s turbos are garrett gt28rs' thoughts?

There is a guy with a 350z getting the Twin Turbo kit from GTM, here is the thread:

my mate has one in his 370z.... these are shit. Nothing lined up, tuning software was rubbish, they are a pain in the arse to deal with post initial sale. EVERYTHING had to be re fabbed.... not even the intercooler sat straight......refabbed

If you were to spend big $$, go for HKS Twin turbo kit, Greddy kit aint too bad .

[V(35)Powarh!]

Yea apparently a really long wait for the items and the service is non existent with these blokes but ive done the reserch and its the only tt worthy of gettin really... apparantly the greddy don't make for rhd and hks do a kit for 350z but seems to be discontinued?? The gtm kit there has been mixed reviews

Dan I think I spoke to the garage that installed ur mates 370z he said the same thing pain in the ass to fit apparantly cause he purchased lhd instead of rhd I dunno ive had mixed reviews some say its a great kit others not so good so kinda on thr fence on this... thanks for the thread spoke to matt from east coast customs as well great bloke very helpful gave me his opinion on supercharging the v but at the end of the day tt looks the way for me potential for bigger power and dat boost kick

How much are you willing to spend?

Are you planning to build the engine?

Two turbo's is extra expense for no real gain imo. A single will make for easy power also. Speaking of which, how much power are you chasing?

[V(35)Powarh!]

Hey scotty yea I know just seems like there are more tts on the market rather than s/t

plan is to boost the car without the engine building so low boost looking at 250-300rwkw

My mates 350z has the aps tt and that kinda sold it for me but they aps dont make the tt kit anymore and the place in syd where I got a quote for advised the gtm tt kit

[scotty nm35]

So build your own single kit. I have the manifolds...

Shame I was willing to sell my GTX3076 kit a few weeks ago, but I ended up just putting a smaller GTX3071 on the kit I had.

[V(35)Powarh!]

I wouldn't reallt know where to start hence why id prefer a shop do all the work I know you were but id rather buy brand new but thats just me... still doing the research

cheers

[scotty nm35]

Fair enough. Prepare to get raped then.

If you were local I could make the parts. Custom fabrication will give you a much better result than any off the shelf kit I have seen... as long as it's done well.

[V(35)Powarh!]

Yea I know mate been quoted $17k driveaway on the gtm tt kit as the garage I intend to get the work done advised me they have the gtm kit as previously they had the aps which has now been discontinued.... I know a few 350z' who have had the aps kit installed there so I know the guy knows his vqs which gives me some comfort however alot of people on the zclub forum has had really bad runs with gtm where they have waited really long for the kits to be shipped and received and the lack of service when things go wrong I.e missing parts and what not but then a few places ive spoken to say the gtm kits are great so who knows now!! Was gonna get the kit myself then get the garage to install and tune now ill confirm whether they do have the kit ready in thier shop and be done with it

[scotty nm35]

Far... Wat? That's more than the car is worth.

I was offering a 400+kw capable kit for $5k, and mine isn't laggy at all. I'm telling you, save your coin. Research, find a good local fabricator and make it yourself.

[V(35)Powarh!]

Thats the thing how do I know where to go to in nsw? I always thought it was easier to just get an off the shelf kit if I get someone to nuild a kit whats does it entail and how much am I looking at spending? Thanks

[scotty nm35]

If you could find one of the old HKS single kits that were discontinued, they would be your best bet. Mine craps all over it flow wise, but I would need the car here to fabricate it.

Otherwise, get into the fabrication forum and ask around, I am sure someone can help you. I could make some parts for you and ship them up worst case.

It's very tight up there, but a single turbo hidden under the head low mounted is pretty low key. Send me a PM if you would like to see photos of my creation, even if it just gives you ideas...

Oh scotty, you're tempting me right now. And here I was thinking id go the s/c route next year.

[scotty nm35]

I have a few spare VQ25det manifolds here...

Save your coin and build the motor instead, or just run it on e85 and crank the boost up.

a stupid ques maybe

but... in Melb can we get e85 for daily drivers? where and what cost per litre?

[R6n350GT]

in QLD E85 is $1.26 to $1.45 , usually 20c cheaper than 98

but you will need

Haltech replacement ECU

1000cc + ID or IV14 injectors

Haltech Flex fuel sensor

Stage 2 at least return fuel system from CJM (-8 supply line, -6 return line, rails, fpr)

Walbro 485 fuel pump in a modified fuel tank housing

Maybe Surge tank or CJM twin pump housing if your going above 450HP

[scotty nm35]

I don't know who you have been speaking with Nate, but unless you are running big numbers, that fuel system is overkill.

Osirus, Aeromotive 340L pump in stock housing, stock fuel lines (or swap to Stagea return system) Xspurt 1000's and you are good for 350 odd kw. More than you would want to push the stock engine...

Melbourne has about 60 servos selling e85, just look for the red flags.

[R6n350GT]

hey scotty, my walbro 485 runs out of fuel at 450-75hp above 5000rpm 12psi

fpr starts at 40-50, heads upto 80 and drops down to 70 and holds.

Spoke to aftermarket industries fuel guru and he said 462lph is max of that pump at that power so it just cant keep up..

tuner said he cant do anything as its leaning out while he is trying to tune it

ill upload the graph, one sec
