Hks Gt3037 Single Turbo Supporting Mods And Tune

[V(35)Powarh!]

Hi guys managed to get my hands on one of the above kits for my v35 6mt. i have found topics on this before but just wanted to see anyone out there who has fitted these to their v35/350z in nsw? Im looking at finding a tuner who has vq knowledge or have done a few of these as i want a reliable boosted car. Also wanted to see what power you guys had in these as i know its about anywhere from 230-280rwkw and on what psi? One last thing can anyone recommend good injectors and fuel pump and ecu? Any help would be appreciated and so keen on boosting my car.

280kw will never be reliable unless you run e85. The rods in the VQ35 are very light so you would need forged parts to make it reliable. 280kw is fairly easy out of this kit, it could make 340 or so on ethanol pretty easily.

I can supply injectors and pump cheaper than most if you want a quote.

Ecu wise, Haltech. You can also remap the stock ecu to some extent using Osirus, but the Haltech is the go.

200rwkw at 6psi.

And it not power that kills these motors, it's the huge amount of torque you can generate at low rpms, that stresses and bends/breaks the rods. You need to find a way to limit that.

I experienced full boost at 2200rpm.

Yea ill keep tuning on e85 in mind excuse my knowledge but how safe and is there still a chance the rods will go even though its tuned on e85? Which haltech ecu? i think there's a platinum pro and the elite which the guys at haltech spoke about when i called them today. Alex what figure dod you start off b4 the turbo kit was installed? Im surprised i would have thought at least 240kw? I guess every car/ dybno is different?

how much nm of torque did u end up with?

[PN-Mad]

The kit added roughly 70kw.

Yes, there is absolutely every chance the rods will go on e85. Just accept it as a risk, and if it ventilates itself then build one up.

No torque figure. Can't measure torque accurately on anything but an engine dyno. Too many other factors going on.

Yeah, my power might be a bit low, but it was running the same boost, afr, and ignition timing as a lot of US cars claiming a lot more power. Dynos are different, operators are different, especially those damn Mexican ones hey Scotty

[scotty nm35]

Don't let it deter you like it did Alex though, I have seen what a 280kw 350z goes like at the track, and I would love one.

Just don't stand too close to the engine when it lets go, I still have burnt leg hairs from standing beside a turbo V8 Soarer when it threw a rod on the dyno. Not pretty.

i would be keen for higher power but i dont think i can afford buidling an engine, paying for this turbo build is already enough! say what another $10k to build it no?

i think im going to go 1000cc injectors and fuel pump from deatsch werks as ive heard the walbros are noisy but that could be cause they arent legit, the dw's look good quality imo...a few tuners ive have spoken to are tunehouse in marrickville, toys garage in fairfield, tom at bd4s however he referred me to powertune in wetherill park so did haltech and they also mentioned micks motorsports and i have spoken to crd in croyden and lastly autotech engineering i know have done a few aps kits......any tips and if yas have had work or heard of theirs please chime in.... any feedback as i would like to pick a tuner and get the kit installed as soon as funds are available.

[scotty nm35]

I sell pumps and injectors, but I won't do Deatschworks anymore, too many issues with them. A genuine Walbro through me is $110 (cheap as chips) flows 400kw and should be nearly silent if you don't go bumping the fuel pressure sky high. I run two in my Stagea and can barely hear them. DW are just like every other made in China pump imo.

If you can't afford to build the engine, perhaps a few times, don't chase the power. If it ends in tears you can't blame anyone but yourself at the end of the day. There isn't any warranty in the tuning game and doubling the power of an engine has it's consequences.

[V(35)Powarh!]

exactly right.mate and thats why i will most likely go conservative tune and be done with it...be happy with anything between 250-280 more than enough for a street car...i will look into the pumps and injectors now im in two minds.. but thanks for the comments boys will keep in touch with the build when it gets started!
