Twin Hks Gt2835's.

[Turbz_13]

Just after some info on these. As iv got a set. And dont know weather to use them or sell them off for a t04z.

Iv got the inturnally gated set, that sits in the stock looking position.

What are some good supporting mods?? ie cams and stuff.

Cheers

James.

One of my mates has apair on her JZA80 - very laggy...

[Turbz_13]

Cheers. Yea iv found heaps on 2jz's running them hey.

[R31Nismoid]

Well twin 2835 should be 450-500rwkw.

There is a better choice than the ole T04Z anyway mate.

[Rolls]

what power are you aiming for?

LS1

[paulr33]

i reckon a T04Z would be heaps better

[Adriano]

Isnt charlie(NXTIME) running these

[Turbz_13]

Mine are the bolt on standard position ones. So they are a bit smaller than he high mount kit. I think 0.6 front and 0.640rear.

Wanna push them high 300's plus. Got the engine and Haltech ready for support. Now turtle things like cam size injector etc.

Its gonna be a dog to drive. But its not going to be a daily.

[Turbz_13]

Although iv been told thr are bigger than gt-rs'

Come on mate your talking about getting 2 turbos capable of 450-500rwkw setup and you cant be bothered having a 2 second look at hks site for the different sizes. Either do some serious research or just walk into a quality performance joint and tell them how much power you want and see if you can afford it.

The HKS GTRS makes about 250rwkw on a well setup RB25.

The HKS 2835 Pro S makes about 270rwkw on a well setup RB25.

So yes they are bigger.

They will be one of the laggiest ways to make high 300's.

"push" them to high 300's? They wont even be awake flowing that much! Why not get a set of turbo's suited to you goal? It will make for a much nicer (and quicker) car!

do you have any idea how laggy this will be? I doubt it would come on song until 5500rpm or higher

There is quite a range of HKS spec turbos called GT2835 but the chief thing to remembe is that they are based on a GT30 turbine so the 28 part is marketing slight for what is actually a GT3071R turbo , just ones with cropped turbines .

Long story short they came with GT28 or GT30 based turbine housings and either could have T25 or T3 flanges .

The ones you have would be the low mount GT28 0.64 A/R RB26 based turbine housing version bored out to suit the cropped GT30 turbine .

These are from memory the largest low mount IW HKS spec Garrett ball bearing turbos used as parallel twins on RB26 heads . I would not expect these turbos to be what you'd call responsive given that they are 250+ Kw capable units on their own . I believe they use the same turbine housing castings as RB26 style GT2530's and many people don't even consider 2530s to be responsive turbos on std capacity RB26's .

The bottom line is that you cannot have it both ways with turbochargers and when you have an engine car combination that needs turbo boost to make healthy torque getting some boost in early makes all the difference .

An RB26 is a short stroke short rod medium bore low compression ratio inline six . It is designed to rev and equipt to make good power for the capacity but not at low or what most consider "normal" engine revs . We know its entirely possible to make a lot more power than Nissan did standard with these engins but increasing the state of tune with larger turbochargers almost always pushes the onset of boost higher up the engines rev range . The higher up it is the less accessible it becomes when trying to drive these cars "normally" .

I personally wouldn't have anything larger than 2530s on on a GTR even a dual purepose street/club car . For pure street it would be GTSSs and enjoy the fact that you can have a GTR with good road squirt but without revving the piss bags out of it all the time .

In my book you 2835s are drag race turbos and for a pure quarter mile car not a bad starting point .

I think they are impractical for much else but thats just my conservative view .

pointless post from me but be sure to note there is twin 2835 with internal gate and external gate setups

twin 2835s regardless like disco says is stupid

its a cropped GT30 setup basically

and who runs twin GT30s????

imho for the original poster the T04Z would probably provide much more linear response vs twin that large

[Harey]

and who runs twin GT30s????

Owner of dynomotive runs twin GT3071s on his built 6+L LS1 1 tonner, runs 9s from memory hahaha

[discopotato03]

Yes but thats the capacity equal to having a GT3071R on an RB30 .

[Harey]

Yes but thats the capacity equal to having a GT3071R on an RB30 .

Yes I know, it was meant to poke fun at having the same turbos on a 6+L engine to a 2.6L

Especially to only make high 300s!

[Turbz_13]

500kws it is then

[Nee-san]

What gearbox are you going to run bro ?
