Hi guys, I have a brand new Borg Warner EFR 8474 alloy supercore for sale. Box is unopened. Location is Penrith area, Sydney, Australia. Buyer pays postage. Price is $3600

Bump!

Lip is gonnnnnnnneeeeee

Put it on a trickle charger. Problem solved.

What gearbox?

I wonder how many JDM bell end’s will buy these? #Mines #2.6 and twins for response.

Isnt your car pushing water with a busted head gasket?

-5’s are too BIG for a 2.6. My god they’re a heap of shit to drive on a 2.6. Again, have you driven that setup? You’d be pumped to the moon and back by a euro hatchback. I wouldn’t piss on those new journal bearing shitheaps from HKS. Waste of time. You may be only looking at where they “fall off”... but how they drive and how the come on is chalk and cheese. The GTR is a big, heavy heap of shit with tall gearing with the 5 speed and can’t be helped by any “smarts” in the engine bay (like VCT). It’s a small stroke, low comp donk with a dumb head. It needs all the help it can get to push around that pork! It’s ok, I own one, have had for 15 years. But to own one with a 2.6 is a no go for the above reasons.

Have you driven a decent 2.8/stroker RB? Building a 2.6 is a waste of time. Less text book, more get in and drive it. Having had a Tomei 2.8 in my car for 15 years, if someone said that I HAD to run a 2.6, I would sell the car. They couldn’t pull a skin off a custard. It’s made out like the rings are worn in 2,000 kms and it needs a rebuild. Realistically, it would have spun a bearing or the car would have been sold on by the time it needs to be “serviced”, especially with turd twins which you won’t be revving north of 8000 rpm with. There are positives AND negatives for every RS ratio.

When every dope puts an auto in their gtr to make it a 4WD VL?

What’s wrong with it? If you want a 6 speed box (5 speeds suck), that cops the grunt what do you put in? A Getrag is getting up there in $$ now. Going to reverse is hardly a big deal. If you’re going to go to reverse then you’d be in 1st. Push the lever up to neutral and push it up again. Hardly a big deal.

That’s great news. About time someone pulled their finger out. Hopefully they have a few different grinds. 👍

Yep. A fair bit of shit going on.

Small issue though. The Kelford blank for an RB 26 won’t have all this stuff going for the Vcam to work. If it was as easy as regrinding a blank then it would be a piece of piss.

Sad thing is, with a >500 kw GTR, the driveline costs to do properly just as much as the engine. Anyone can chuck a big turbo at it, making it reliable and useable is a totally different kettle of fish. Diffs (front diff on these things are THE BEST MOD YOU CAN DO), transfer case and box. *insert throwing cash out the window .gif*

OSG 5 speed assuming a 265/35x18 tyre, 4.11:1 diffs and 8000 rpm is 87 138 190 234 290 or 310 using the stock 5th ratio. Factory is 75 120 180 234 310 Having spent the time, effort and money OSG 5 speed (and breaking it with 470 rwkw), it really is a sideways step. Same result as a factory box (they break) and the gear ratios SUCK. They’re just too tall not to mention the 5 speed setup isn’t the nicest box to shift. Getrag’s as mentioned above are not worth it anymore BUT they are a much nicer shifting box. With the 3.0 you won’t want a Getrag/4.11:1 anyway. Be rowing gears like a stock evo BUT a 6 speed does wake the car up so much. Question, IF this 5 speed doesn’t last behind the 3.0/8474, what will you do then... apart from put it up on jack stands and cry. It’s a shame there isn’t a decent synchro 6 speed box that is strong as an ox, large input shaft, synchro that bolts straight in and can get replacement parts for. It’s one of those things as a GTR owner is almost like a rite of passage. Up the grunt, build a big donk, blow the driveline to the moon. Bit like realising you’ve spent 10 years playing in the sandpit with twin turbo’s thinking they’re the “way it has to be” 🤣.

You would need to confirm the lobe angle of the step 1 cam. The step 1 is only wedged on 1 side so you would think/assume the lobe angle would be different than a step 2 BUT I can’t confirm that as I have no measured it. Rb25 and Vcam cam shafts have nothing in common. This is essentially an EJ25 system that has been shoehorned to make work on an RB26. You’d be better off asking for an EJ25 nose and grooves that has the lobes spaced to suit an RB26 with a profile of “x”. My bet is they won’t want anything to do with it. 🤣 The thread below has photo’s in it showing what I’m talking about. https://www.gtr.co.uk/threads/vcam-step-1-and-stock-turbo.504185/

So Benny carried out a turbine housing touch test. After a 20 minute drive he touched the compressor housing, that was cool enough and then dropped a finger on the turbine housing. Even the 1.05 T4 was hot. This was the result. 🤣

At what turbine speeds? Both of those look far from “all in”. Considering an 8374 will piss in 600 whp, why are a 8474 and 9180 which flow far more only touching those numbers? Have you you got a decent exhaust on it yet or does it still have that 2.1 inch thing you said was on it a while ago? If that has not been addressed you are wasting your time.

But it doesn’t exhale as much 🤷‍♂️👍😂

You can put that 73.7 mm crank in the bin... where it belongs.

About farken time!

Bump!

Go downstairs, start your car and put your hand on the turbine housing at idle. Please take a video. ?
