How to spot an R34 RB26.

[tl1000sga]

Ok, my R34 RB26 is supposed to be here tommorrow, but I need help to make sure Im getting an R34. I know the differences between 32's and 33's, but I need to know how to look at it and tell its an R34.

Before anyone starts flaming SEARCH SEARCH. I have been searching the furoms for hours now under broad searches like RB26, and RB26DETT. None have answered my question. The closest I found was that an R34 will have a red sparkplug cover. Can anyone confirm that?

Thanks guys.

spark plug cover are comical. All rb26's have the valve blow by hose in the rear some have dual turbo's some have single (if modified) Check the block stamping on the left hand side just before the transmission. The valve covers are totally different than an rb25det and rb20det. Ohhh the intake manifold looks like a greddy. Ha the oil pan is a dead give away, it has a huge differential on the right hand side that connects to a prop shaft then to the transmission. The oil pan is cast aluminum. Other than that send some pics we'll point you in the right direction.

Your CAS will look newer and will be black plastic looking instead of the traditional bare aluminum one with the little black dot in the middle. It will also have VVTi or whatever Nissan calls it. Everything else is pretty much traditional RB26DETT. The Valave covers should be Coca Cola Red if they are stock color and the Turbines are ball bearing. That is all I can remember for now.

Thanks, I meant differences between RB26's only. I know the differences between the other RB's.

I want to make sure that I'm getting the R34 RB26DETT that I paid for and not an R33 RB26DETT.

Thanks cursed, that should help. And by CAS you mean what?

[CursedGTR]

The Cam Angle Sensor on the Exhaust Camshaft. It has a 3 wire harness coming out of it and runs across the engine to the left towards the intake manifold. Hold on and let me see if I can get you a picture of an R34 Engine.

[CursedGTR]

Alright here you go.

The first 3 pictures are an R34 motor.The 4th Picture is an R34 n1 motor. However the CAS is on the right side of the front cover so you can see what an R34 CAS looks like.The 5th Picture is an R32/33 CAS. Hope this helps.

Thank you very much Cursed. With that knowledge, I am not to worried about checking the engine tommorrow.

wait, no rb26dett ever came with variable valve timing........

[eh?]

1) red or gold valve covers2) Black CAS3) No ignitor on the back cover. The coil packs are the same as the sII RB25

if you dont mind me asking, where did you get the r34 rb26dett from?

[CursedGTR]

R34 Motor had VVTi - Here is the HKS part description for the Valcon System that they use to control it. Also here is the link to the page.

In the VVT-i on-board car, exchanging the camshaft, it becomes the valve timing which it adjusts to the normal camshaft, the effect of camshaft exchange fades. With HKS, developing the valve timing controller and the camshaft with set. By the fact that you set to the optimum valve timing which is adjusted to the camshaft, camshaft original efficiency is made to show

I'm pretty sure they didnt come with VVTi either, but HKS does make a vvti system for the 26... so maybe thats what you are thinking

I sourced it myself. Been looking for almost a year now. Funny thing is, I looked for so long, but then I sourced 3 at once.

Its a friend of a friend deal, so I am waiting to see how it pans out. It will be delivered to my door monday.

If you are interested let me know, as I may have 2 more to sale if I am satisfied with the deal.

I was under the impression they had VVTi, or whatever nissan calls it. But I will know soon, this will be the first R34 RB26 I have dealt with. Can't wait!

Its VVL or CVT , and it does not work the same way DOHC Vtec works. They are different. It actually works more like SOHC vtec. without the lift.

No it's VTC or CVT not VVL. Nissan NEO VVL is basically the same as Vtec.

R33 & R34 RB25's have some form of VTC. No other RB's had any form.

[CursedGTR]

That works for me, looks like HKS just makes the V-cam dealy. I am still curious as to why my Apexi Exhaust Cam would not be compatible with the R34, but that is only curiousity.

[Carl H]

from what research ive done into cams (when i was looking for some for my motor), the r34 uses a diffrent 'tong' in the exhaust cam to drive the cas, proly why you cant use a r32/33 exh cam on the 34.

Look up the website batfa.com it has all the skylines from gts-t up to r34 all for sale. as well as hondas, mistus, toyota, and subaru. There are a couple others and stuff but im not sure. But i have seen some 180sx's on there for nothing and it costs 1500 for shipping(because its in japan). They have so many cars and IMO even with a 1500 shipping price its cheap. But that said i dont knwo how much it will cost to U.S. legalize them.

[StricNyne]

the cam setup is called nvcs or nissan variable cam system, i think i saw it on wikipedia

[CursedGTR]

Cool, now I can go back to working on my R33 motor, without anymore distraction.
