Turbo choice

[Jacko85]

Just looking at turbo options, how come it is not common to see g35-900/1050 fitted to stock manifold.

Is it due to the fact stock manifold cause a restriction at about 500RWKW

There will be plenty of reasons and most of them are just individual preference. Of course the manifold is a limiting factor with bigger turbos.

 

If you wanna chuck one on then go for it. The g900 would be a good upgrade over stock.

 

Before you buy an expensive turbo, you need to sit down with your builder and tuner and go through your goals and expectations to make sure you're on the right track.

The main reason is the G35 900/1050 don't come with a standard T3 rear housing, and as far as I know, they don't fit inside the stock rear housing. 

You pretty much need a vband manifold to suit, external gate etc

According to the Garrett website both of those turbos come with a 0.83 and a 1.01 T3 inlet.

[Tom Tucker]

Yeah, you're right, I think they added those only recently. 

Maybe the 1.01 is workable, but you still need an external wastegate setup. If you modify the stock manifold, it usually doesn't end up that much cheaper than new manifold.

Point remains, its not a simple bolt on job with a G series

[Puffwagon]

Yeah looks like they did.

 

Not much is truly bolt on, the Falcon stuff is not generic Garrett stuff.

[Tom Tucker]

I guess it's different to the GTX stuff that bolts up to stock rear housing. 

Just saw this, 670 odd kw from G35 1050 (I assume)

 

 

Looks like its lazy compared to my G35-900. Seems to hold boost a bit better, but similarly looks most efficient around 20psi.

[Puffwagon]

Yeah there are a multitude of differences in the fitment of various products. Anything will fit if you want it to, although the level of modification will greatly vary.

 

Edit: Haha gotta love those inflated SA hub kw

I am trying to work out my build atm. I am trying to do as much as I can myself and have built engines before. I want good power I have not really set a figure. I would rather 400-450 with good response vs that 1050 in that video that seems laggy then jumps like 450kw in 1000rpm

[Puffwagon]

The 1050 is a bad match for a stock manifold, despite other mods that make it work.

 

The turbo you want is a gen 2 gtx3582r. It'll make that power on 98 and will easily make 50 more on E85.
