wheres the best place to order one of these bad boys, should i be looking in the states or australia?

 

The cheapest place I have found selling them for are the following 2 places in England. I’m looking at a 7670 T4 external gate and the cheapest i could find in Australia is $2875, the 2 below are $2030 posted to my door.

If you want to buy locally email mtq, munt-WA said he got a good price on a 9174 from them. Turbotech list their prices and are cheaper than anything advertised I could find in Australia

OK question time. 

- What would be the best option for a solid 375-400rwkw in a stock bottomed RB26? Has headstuds, e85 setup, 76 plazmaman, cam gears already. 

- Could I potentially low mount this? 

- On what manifold? 

- Are we all agreed that the IW setup on these is good enough or is an external setup going to be better?

The goal is maximum response to improve over -9s on a street car. I may also move to Kelford L182-A cams and springs.

Will a 7670 get me there? My tuner just said a basic 3582R and a 6 boost would do, but these appear more responsive plus the smaller size means I have better chance of low mount. If low mount is too hard/expensive then high mount it will have to be.

I don't have any results for that type of setup and low mounted.

 

Why not give it a try and ignore there tuner like most people do and see how it goes ?

400kw would be pushing it on an EFR7670 but high 300kw @ wheels with epic response should be doable.  I wouldn't rely on an EFR7670 being a lot smaller than a GT3582R, haven't seen one in person but they're not little things.  I'd definitely go external with an RB26, partly because you'd want the 1.05a/r hotside.

A GT3582R would clearly do it easily but won't touch the 7670 for response.

I tried to get my 8374 low mounted. 7670 is smaller, but only a little. Low mount isn't happening unless you find a solution for a gt35 low mount.

7670 ewg would Max out at your power goals. Should be a highly responsive turbo for the power.

[No Crust Racing]

Thanks Pete, are we talking max at 375 or max at 400? 

They're an ugly turbo to want to high mount. Dare I say the Precision is prettier to look at? When you see a full 6262 setup for $2300 (manifold, EWG, Dump. turbo, and lines) doesn't look like a bad option. 

 

[Lithium]

Maybe @Full-Race Geoff may have some inside word on when the new EFR housings may become available?  They look a lot like the SX-E housings which imho are some of the nicest looking units on the market, a far cry from the ugly things currently available

 

[Piggaz]

This whole ugly turbo thing. Seriously guys, man up. You won't be worried about an "ugly" turbo when you're driving the thing. End rant.

What Dan said. 7670/1.05 would be an amazing setup on a RB26.

To draw a comparison, Benny from Benchmark tuning has put a fair few 7670's on EVO's. He says th basically drive like the factory EVO snail... but go onto make north of 400 Kw wound up. It would make the typical "-7/-9 2.6 build" look rather silly.

[No Crust Racing]

400kw on an 4 cylinder but people in here saying it will struggle to do that on a 6cyl with .6L more displacement 0_0

[Piggaz]

A bloke in the UK did that exact setup. From memory it went 575 HP. Can't remember fuel or boost as it was a while ago.

Dan, link to build thread.

It was the 0.92 IWG setup, sorry.

[sneakey pete]

Why do you think displacement will make any difference?
Compressor can only flow what it can flow.

Doesn't matter if you have a 1L or 6L engine

[No Crust Racing]

Because total power is not just about what airflow the turbo can provide.

Fair to say 6L will make more power than a 1L yes? Adding the same turbo to each doesn't magically mean the 1L will now make the same output as the 6L.

So I'm surprised a 2L will make the same/more than a 2.6L with the exact same turbo.

Then again were talking 80s engine vs much newer design...

Combustion efficiency vs air flow.

The increase in efficiency is rather small for your initial statement to be relevant.

Pretty sure you'll find posts on here (in the original EFR thread, in fact) that suggest that an increase in displacement will typically shift the power curve to the left, not offer you additional top end power.

Garrett's 3582R has an 82mm compressor and can reach you 400rwkw target

BorgWarner 7670 is a 76mm compressor, will be out of breath at 400rwkw but may work well for 375 and quick response

BorgWarner 8374 is 83mm compressor, and pumps out 400rwkw easily. 

Internal WG has its benefits (simplicity, cost) especially with EFR twins.  But when looking to run a single at high boost and high rpm, external WG is typically more popular.  it requires the gates, dumptubes, flanges/clamps etc

spend some time with matchbot, videos at the bottom of the page explain how to use it: http://www.turbos.bwauto.com/aftermarket/matchbot.aspx

Yeah that ugly integrated bov on the compressor housing that gets rid of 2km of factory bov pipe work out of your engine bay. Got a link for this brand new $2300 Precision 6262 kit?

It's a gtr, it sits in the shed and you look at it not drive it 

 

If you can wait until May next year i will have results on my 7670 T4 external gate vs -7 twins.

I tried out the 8374 and 7670 on an HKS bottom mount. Issue with the 8374 was the compressor inlet sits too close to the engine mount and also fouls the oil supply port on the block. 7670 sits much better, will have to use a sharp angle for the intake pipe right off the compressor to clear the mount. I'll dig up some pics and post them later. . .
