[Closed] Borg Warner Efr Series Turbos

[reaper]

Not as yet I only received it this week! I plan to put it on in December as I have a few other parts I need to collect to upgrade the fuel side of things at the same time

I'll take some photo's when i'm doing it all if you would like

I'm interested to see how they added the VQ35 hydraulic cam actuator to the front of the camshaft and got it all to work.

My VQ25 runs an electric clutch CV arrangement instead, which may be easier to retrofit as it doesn't need the hydraulic lines. I always wondered why HKS went the external oil feed path... If you could post pics in a Vcam thread I would appreciate it.

Should be a great addition, but I hope you have the valve clearance. Those actuators can advance 50 degrees. Who will be tuning it?

[reaper]

Oh sorry I thought you meant about the turbo install.

I actually bought the car with the vcam already installed. It's currently running the the vcam controller and an fcon v pro which i'll be keeping for the time being.

Will be retuned on e85 with the new setup and will more than likely be done by tunehouse (fairly limited when it comes to tuners that can tune an fcon and vcam)

It will be more responsive and make more power. Everywhere. A guy on NS put a 6758 (bigger) on his SR and it was a bit like a V8 in terms of delivery.

Wait for the 7163, that might be a game changer.

If I got the 6258 and a manifold to suit, would would I have to convert the rear housing to a t3, or is it feasible to run a t25 housing on an rb? i.e. too much of a bottleneck not enough room etc.

No it will be fine. The best thing to do will be to have a good fabricator cut off the T2 flange and weld on a nicely shaped reducer and a T3 flange.

The housing is stainless so you can weld on a stainless T3 flange no hassle.

Read the last 5 pages of this thread as we have been discussing exactly this (i want a T3 7163).

Also, is go a bit larger and get the 6758 or 7163 as the 20s like to rev :-)

Just thought i'd post some photos of the 8374, now to put it on an evo or finish the gtr eventually?

[Piggaz]

GTR!!!!

[Lithium]

MY GTR!!!!

FTFY

[cobrAA]

GTR!!!!

+ 1!!

Fit RB26 to evo?

[NismoSTune]

I'd say Evo, those things are lighter and handle better with not much more lag on that turbo (compared to the gtr)

[Skepticism]

Bump for 7163 info

[bradsm87]

New turbine/housing options listed on match bot too.

Also found an awesome read on mixed flow turbine wheels with a mention of the pros/cons of using TiAl - http://www.hindawi.com/journals/ijrm/2012/589720/

Needless to say, I'm very excited about the 7163 in 0.80 twin scroll (although I hope the 0.80 comes out for my 7064 because I'm not changing turbos any time soon)

[Skepticism]

Yep.. I just want a release date :|

interesting article btw
