You know they sell cams for the RB20. I have Tomie cams in mine I think they are 720 or something. The Rb26 cam seems like alot of work for so little gain.

yea i had found some cams for the rb20 but some guy on the forums said that the rb26 cams would b a great upgrade for me.so i wanted to c if that was true.what kinda tuning did u go wit on your car wit the cams in it? thanx for the response

I haven't started the motor yet since I reswaped it into a S14. I was thinking about GTR cams at one point. After reading I didn't like the results that I found on the Skyline forums. So I just spent the extra cash for the Tomei cams. Carls 260's worked great for him so my 270's should have the same effect.

yeah, car pulls hard to 8k, cant complain about that.

[RBKIDD]

what tune ru going to use

[Yellow4g63]

I have a AP power FC for the rb20.

[nizmo zilvia]

Anyone selling rb26 cams or kno anyone who is? I might just invest in them.

i've got a set i've been holding on to as a spare. not dying to sell them, but make me an email offer.

[Carl H]

wouldnt it make more sense to get the car running first?

[nizmo zilvia]

Yea but I was just curious. If I find it for a good price i'll save money later on when I need them? No?

[RBKIDD]

were did you get ur power fc.and how do u like it in terms of tuning.how did u start ur rb after u did the upgrades with the stock tune on the ecu

[Yellow4g63]

I bought it on Nugen.com before AP engineering closed it's doors. I think that was 2 years ago? I would have to dig up my old post to know for sure.

I put rb26 cams in my rb20 and they're sort of worthless without adjustable gears. If you just look at the specs of the rb26 cams vs the rb20 cams its an obvious upgrade. I'd sell my cams if someone was interested, but for now their a paperweight until I can afford gears.

The skyline forums thread about rb26 cams is 900 pages of nearly useless information. Sydneykid made some pretty decent gains with the gears, time after time... I dont see why thats a useless upgrade, and I dont see why it would be any more work than any aftermarket cam.

Here are the specs I recall off the top of my head:

RB20IN: 240 degree duration 7.8mm liftEX: 232 degree duration 7.3mm lift

RB26IN: 248 degree duration 8.5mm liftEX: 248 degree duration 8.5mm lift

It was something like that... I didnt find any usefull info for myself on the internet, so I took the risk and tried em out for myself. If you can pull it off you could probably save about $500.

Good luck

[RBKIDD]

o so you have to get a specific one for the rb20?and let me guess they dont make them for teh rb20 anymore rite haha?

All the real world info you could ever need.

[RBKIDD]

thanx

[DriftingisLame]

Of the 900 pages on that thread, this is probably some of the only usefull information I found.

SydneyKid:"1. We have, 4 so far 2. None 3. Very much depends on what else you have done. But from what we have seen, you will get; A. earlier boost build B. faster throttle response C. about 15 rwkw increase in the average power from 4,000 rpm to 7,000 rpm D. about 10 rwkw increase in max power

If you are on a budget and can do it yourself it is very worthwhile. If you can't DIY then you may well be better off spending a few hundred extra on used aftermarket cams, as the fitting cost will be the same. As Autobarn suggested, there are a few HKS 264's around that are a step up from standard RB26 cams

Hope that helps"

He later says with adjustable gears, +2 IN -4 EX is a good place to start tuning at.. Otherwise you're car will idle like mine! LOL

So are there any other drawbacks to installing the 26 cams without cam gears and timing other than the rough idle?

Will you gain the same amount of power, if not, how much less?

BTW, I do plan on reading the linked thread, however, it's going to take a while for me to get through the whole thing, etc. But I do have a set of 26 cams that came with my car that I was waiting on putting in until I get cam gears, however, if I can throw them in and only have to put up with a rough idle, I'll do it now and throw in the cam gears later on after I get the other, more expensive upgrades done.

Thanks,Gary

Wait until you get the cam gears and have it dialed in correctly. Having the timing off at low RPM/high load will put a lot of stress on the motor. Do it right or don't do it at all.

I'm not sure really, it might vary from motor to motor.. Seriously I didnt gain much power, just pulled smoother after 5000 or so, and didnt drop off until redline. The idle and loss of torque is not worth it. Thats why I took mine out.. I'd suggest getting the gears first, so you save yourself some work you know? Do what you want but it might really start to bother you.

rb26 cams with gears should be for the win.

[the_garynator]

Thanks guys, I think I'll wait till I get the gears.

I had a rb25 with an ex cam from a 26. Before I had both intake and ex. But I didn't like how it pulled so I put back the 25 intake cam for VVT and left the Ex cam in. That combo seemed to pull harder. And sounds nice at idle too, but does smoke at all like in the video. At first when they were both installed had to do some adjustments on the PFC. Had a set laying around and I pick up a set of cam gear for a gtr for 50 bucks and had nothing else to do.

when you installed the rb26 cam what timing did you use i got a set of rb26 cams that i can put to work instead just chilling in my garage ....thanks Danny

Don't remeber off the top of my head but I will post it when I get a chance to look it up in the Tomei book. You got adjustable cam gears right. When you install them your going to have to adjust the computer for idle.
