M35 Single Turbo V6 Setup.

[Tonkachow]

Turbo M35's.

Can you please tell me how the single turbo is setup on your cars.

I am just curious as the whole thought of slapping a TT on the car seems silly if you can get a big single in there no worries. I think the 3.5 would handle a big single well with minimal lag.

So can you explain to me how they do it on your cars.

Is there a cross over pipe from one bank to the others?

Is the turbo mounted low in the bay??

etc etc.....

Cheers.

The NM35 HAS a single turbo set up.

It's low down on the passengers side, and brings a balance pipe around the top of the bellhousing, joining into the passenger side manifold. The space is limited, and this compromises manifold design, and turbo size.

I would imagine the issue with twin turbos is interference from the steering column on the drivers side. Still, there are TT kits for 350Z, and the basic architecture in the engine bay is similar, so I'd be looking that way to begin with.

also the 4WD system gets in the way of the driver's side area

I have a manifold here, I think it will bolt straight up to yours but the turbo is too small and I havent seen a bigger turbo that will come close to fitting.

If you wanted to go down the custom manifold route, a single gt30/35 on the lower passenger side should still work.

What are you thinking?

if you wanted to check out exactly how the system works I have my motor out atm in Gladesville.

It seems you are the most experienced in this. I was reading about the G 35 APS kit. I'm just thinking the most reliable easily accessible heat efficient option.

I'm sure you have covered every option out there. Feel free to fill me in on the positives and negatives on them.

The more I look into it. The more I feel Nissan didn't want this car modified.

Yeah, I think its been worked out that the VQ25 turbo set up would physically bolt on to a VQ35 straight up. But the turbo couldn't handle 3.5 litres of grunt

When looking for turbo kits, you have to account for 2 things mate- 1, has to be able to fit a RHD, and 2, has to be able to fit a AWD. So what your looking for is a G35x turbo kit, that can be mounted for RHD. Have a look through this turbo kit site. I don't know where you would go for engine management, if you went down that path.

Alternatively, there is plenty of supercharged kits out there too! lots of options

Might do that on a spare weekend. How long will it be out for mate?

Bejesus. Options galore. Thanks.

Anyone bought anything this expensive without being hit by massive tax at customs.

Most of the kits dont have a very good manifold setup and you have to ditch the airbox on the single kits. It would be best to custom make a manifold for your choice of turbo and the new gtx Garrett turbos would be the pick atm. GTX 30 .82 in the stock vq25det location would flow enough I think.

Unfortunately the rods in the vq35de are thinner and weaker than the factory turbo rods, this is to help them rev. I would suggest new bearings, pistons and rods from the states before fitting any forced induction kit.

Ok that makes sense. That's extra coin I hadn't counted on in the immediate future, but I guess that's why I am asking.

forever.....it's the broken motor!...lol

Thats why most of the kits seem to be set around 6 psi... some up to 8.5. Way below what the turbo's are actually capable of. If you were to do it, I guess mount up the twin kit, drive it and sort the gearbox while it makes 6 psi. Then when the banks recovered, go blow up the motor with some boost and rebuild with some capable internals

Either that go leave it NA and tune that way- which is easy too...

Anyway, parts for our cars mainly come out of the states- the G35 has a massive following.

If I had unlimited coin I'd buy just about everything here to make a high rev NA VQ35. Swappy gearbox to MT / RWD and reduce the weight... somehow

Every time I look at that inlet manifold I get a stir downstairs!

yeh Cosworth make some got shit!

Bahh, engine driven superchargers are for pussies, unless theres a turbo in front of it...

The 6psi limit isn't because of weak rods, it is due to detonation as the stock compression is too high for FI. This can easily be rectified with E85, unfortunately the rods will break with the extra torque and when that happens there will be no resurrecting the engine.

Actually, even the kits that lower comp to 8.5-8.8 keep the low pressure.... due to weak rods

i've see thicker drinking straws....

From left to right: HR, VHR, and DE rods.

LAWL!! you got nothing to complain about:

Top: my QR25de rods - im pushing 10psi and 280hp through those :|

Bottom: SR20de rods

[PN-Mad]

yeah, but thats an x-trail.... not exactly a performance car...

(but seriously- thats an awesome build.)
