These are 6758's, if it makes a difference.

How is this relevant to the topic? Make a new thread. Also, look at other cars that are selling that are close to your spec. Shouldn't be hard to see what the market is paying for them.

I'm not sure. I can ask. Would it make a difference and if so, what should it be?

First start up is on Friday!

Here's some updated pics

I do not have a build thread. But I could certainly make one. I'm not doing the work myself, so some details/pictures might be lacking. Let me throw a thread together some time this week and I'll let you know.

Yep, definitely on e85. I figure pump results here locally should be ~600.

Will be done mid-August. The goal was about ~850rwhp, which I think is about 1000 crank hp. Worst case, I can downgrade to the 6258's if I find the setup a little too laggy, but I am still thinking it will be ok in the end. I'll definitely keep the thread updated with all the results when I get them.

I don't disagree with what you've said. I've got high expectations and a little nervous to see the results. I am counting my chickens before they're hatched. I'm just gonna wait until it's all done and givey impression then. Hopefully the results are still impressive.

Not sure of his boost level, but my -5's were all-in at 4500rpm at only 22psi on crappy 91 octane. I was hoping to get the 6758's fully boosted on e85 by then. I also can't imagine that these turbos would be any worse than the -5's, but what do I know.

My -5's barely spooled up fully by 4500 rpm, so I am hoping that these spool up a little quicker than that. Motor spins to 8200 currently.

It might be too late to ask this, but do you guys think the EFR 6758 is too big for the RB26? I'm like neck-deep in the build now, so it's probably too late to turn around, but curious what you guys think. I got them super cheap so couldn't pass them up, so this is my life now.

Yes, I believe so anyways: Pec rods H beam arp 2000 rod bolts arp 2000 head studs 1.4mm tomei mls headgasket tomei pon cam B 260 9.16 graded bearings stock crank blue printed gaskets mls bronze valve guides wossner pistons 86.5mm (8.5:1 compression) Tune for 91 octane and E85. Previously was -5's. I am sure these will perform better in literally every single way. I am excited to get and share results! Probably be up and running around this time in July.

I updated the post. EFR 6758's.

So, this is finally happening. EFR 6758 twins with Full-Race kit setup.

I would imagine that the dyno result is on regular pump gas (93 octane)? Thanks for the info @Full-Race Geoff. Good to see other people with the twin kit. I grabbed the 6758's so I would expect a little more power over the curve past 3500rpm (spinning to about 8k) I believe.

@Full-Race Geoff You might have missed my previous question, but are you aware of any videos of cars using the twin kit? I could only find one video with BMR's R34 on the dyno, but none on the track/road/strip.

@Griffin Start your own. Nothing you mentioned has anything to do with the thread title, which is 'Borg Warner EFR Series Turbo's V 2.0', fyi.

Pretty sure this is the wrong thread for this.

@Full-Race Geoff Do you have any videos of any Skylines with the twin kit doing quarter miles or in-car speedometer/acceleration? There definitely seems to be a lacking of video with cars with the Full-Race twin setup.

Good to know. So, HICAS delete kit then nuke it from orbit. Got it.

Do you mean by method of a HICAS delete bar, or do you mean removed completely from the vehicle?

Oh, interesting. Guess I could go that route too. I did see an electric p/s thread here not long ago. May go that route worst case. Thanks again. Do you have any videos of your car with the twins in action?

Last dumb question: Can it be a non-GTR p/s pump? Like from the NEO motors?

Which GTR was this in? I am working on doing the twin setup on mine as well but am having issues with the power steering pump. Did you have an R32? Did you replace your p/s pump with something else?
