Hello. I have recently bought an RB25. It claimed to have poncams but no specs were available. Removed covers to find both intake and exhaust are 264/264 with 8.5mm lift.
 

Looking to degree the cams- but I can't find any info on a 264 intake and exhaust.

Are these real cams? Or knockoff? Never heard of fake camshafts but there is fake turbos so it's arguably easier to fake cams...

 

Cheers!6B0C81AD-4D30-45C5-B6DB-3DDDF8131D69.thumb.jpeg.6ca6daeb767c5dfae92fb0ae3b8da4ec.jpeg

Really ? That sucks, they had some really good grind selections. Only just sold some new Camtech RB26 cams last week for $500. 🤦‍♂️

Kelfords only now I guess ?

They certainly don't seem current- but I can't find any specs to degree them in!

Just put them on the same LSAs as any other 264° cam, or choose an LSA halfway between the typical 256° and 272° cams' specs. Tighten or widen the LSA by a degree or two depending on how you want the engine to work.

Ages ago I was told that Tomei cams don't need to be dialled in and should always be set to zero ...for RB25 Gtst's.

This was after we dialled in [from memory 5 degrees [could have been 10, it was 20 years ago]] and it ran like shit.  Asking around everyone said to set to zero and it will work.....we did, and it did.

I could be wrong for your motor, but if you don't see gains then zero is your answer.

But Dose Pipe and GTSboy will know more.

Yeah I heard that too- but these seem fairly big for what most run. Probably going to get some stock cams for now- runs like a dog off boost and isn't fun, 120psi across all 6, shitty idle etc

Likely they are 0* right now- no adjustable cam gears so I think for street use stock is fine.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
