[Closed] Borg Warner Efr Series Turbos

[NismoSTune]

How bout......

TWIN T3 6258 and dial the boost down a little... Lol

[scotty nm35]

Scared of a little die grinding Scott?

[GTScotT]

No, I just think it should be said if they have done that many. I'd like to know finer details like if there is plenty of wall thickness etc.

[Full-Race Geoff]

Wouldn't welding on a T3 flange to a T2 housing result in just a little bit of turbulence? ..Not to be a prick, but I have a T3 setup as noted and I WANT a 500HP EFR...

no problem, here is an external photo of this procedure done properly. ill try and get an internal photo next time we do one.. spend some time with the die grinder

That looks like a Tial V band housing, do you have any pics of the process on a T2 EFR housing?

[scotty nm35]

That is a porn rear housing right there. Is the temp probe port tapped from factory? Or is it just a cast section that's designed for the job...

I like the trumpet outlet, very nice. It would flow much better than the garrett/Tial single angle outlets I am sure.

all external-WG EFR turbos (1.05 a/r T4 also) have that nice velocity stack "trumpet" machined into the outlet like that. That bung you see was part of the prototype housings. it was used to record preturbine 'EMAP' to determine the optimal A/R size for the production housings

that photo is a 7163 vband EWG prototype housing for use on an R35 GTR high power build. Weve done the same to T25 also, in fact recently did it for the Modified Magazine Time attack S2000 build. ill try and grab a photo later today of this housing conversion for you

photo of an EWG 7163 that we converted to T3 installed on the manifold. you can see the sideview profile of the turbine discharge trumpet

Wouldn't welding on a T3 flange to a T2 housing result in just a little bit of turbulence? I mean considering the side of the T3 discharge to the T2 entry.. I like the idea but I am not sure this is sound advice :S At least not without better instruction or insight into a successful procedure.

I'm with you. T3 single scroll EW, in a size that my SR20 can spool. You'd have an instant customer.

[NismoSTune]

I don't understand.

They have the 6258, 6758, 7064, 7670 and 8374 available in T3....

I'm a follower of the IWG but do you really need the EWG to kick some ass... Really? They have many different models but people always seem to want what isn't produced. Can't win. I'm sure you wouldn't be disappointed with the IWG, even if you're a hater, you'd be surprised. Less piping too.

But really if you're gonna want a large EWG turbo (guessing you want 500whp?) but want the small frame spool, you should look into a stroker kit, rb25 or even rb30........

[Tom Tucker]

I'm affraid the explanation is fairly simple. My existing exhaust manifold is made for EWG, deliberately, because I think its neater and provides better boost control. All I'm saying is that I'd readily upgrade if the option of a bolt on affair were available

[NismoSTune]

Well i understand then. If you're luck you won't need a custom manifold (or EFR specific one)

[GTScotT]

Its exactly the same for both of us. I already have a really high quality T3 manifold kit and simply need to pick my T3 flanged turbo.

That being said, I feel the 7064 might not suit.. And the 7670 might be bigger than I want to go. I do want 500whp once everything is pushed to its edge, rather than having 600whp up my sleeve and pissing in the desired result. Its just a methodology I want to maintain in my build.

In this case the 7163 is both a little heavier breathing AND has the mixed flow turbine which I am extremely interested in.. This flange swap is also an excellent idea because I can get a housing smaller than .83 AR and which will be friendlier on my SR.

I am with Tom Tucker and will be a near instant customer if a 7163 that suits my needs is available (subject to real world affordability).

[Skepticism]

Anyone know how much shipping is for turbo + mani ?

Depends where you are....

In Ex: a quote From the US to canada was $250 + about $350 worth of customs.

From Fullrace? I was quoted US$420 this time last year for FedEx International Economy 7-10 day delivery.

EFRs have jumped in price $400 since then so it's pushed it outside of my budget

[GTScotT]

US $420 for shipping? That is outrageous.

RSP have not charged me a dollar over $150 USD for shipping on orders with MULTIPLE items including a turbo. Thats $150 USD for a turbo, gates, and other odds and ends all in the one box. Even that I thought was somewhat pricey, but the items would arrive in just over a week. Multiple members on this forum can confirm that RSP charge that sum for a turbo and it is delivered in roughly 7 business days.

Let's just fix some expectations here... We don't need to pay $2,200 for a turbo and $420 to ship it.

http://www.ebay.com.au/itm/BRAND-NEW-GENUINE-BORGWARNER-7064-EFR-SERIES-HIGH-PERFORMANCE-TURBOCHARGER-/121175171912?pt=Motors_Car_Truck_Parts_Accessories&hash=item1c369a6348&_uhb=1

The above seller has a 7064 T3 .83 AR for $1,700 USD and $150 USD shipping. The seller has 31,000 sales with a 99.6% positive rating. Thats nearly $800 in savings, and considering the eBay add has a 'make an offer' function I would be disappointed if I couldn't knock $30 USD off the price, which WOULD make it a saving of $800 USD.

*rant end*

[BakemonoRicer]

is the efr 7064 good for 560hp "At the wheels" or at the flywheel???

im talking t4 twin scroll with 1.05 A/r and dual wastegates

Actually my quote was for an EFR 8374 which is now US$2600.... hence why it now exceeds my budget.

That's ~$3K for a turbo + taxes/duties.

Money no object its a fantastic turbo, but bang for buck it's doesn't deliver $1000-1500 worth more performance over say a GTX35 or a PT6262 BB
