Cam Gears - Is It Worth It?

[Dose Pipe Sutututu]

I cant find any posts here that arent specific to the RB25? Not sure where your reading.

Apologies I did miss the RB20DET at the top, I just saw that all the responses were to do with the RB25.

I have also heard tuners say, its only worth it on RB26's, not sure if they are including RB20s as well?

Highly beneficial, because there is no VCT on RB20s. RB25 motors are blessed with 10 degree advance pre 4700rpm or whatever it's set at. I like pre MBT.

*cries* I miss having a Skyline.

They're just the beez neez aren't they.

Sure you'll have another one soon bud.

R35s are down to 100k now lol...

Haha not sure where your reading either bud.

From what I've been told today, I'd say Poncams for a decently modified RB20DET will be most beneficial, both in low down torque and boost response.

Not one post here has been from someone who has fitted exhaust cam gears to their RB20DET.

Correction, I have on my RB20DET, prior to the days of me knowing anything about tuning, but saying that the boost "felt" like it came on earlier.

Being as there isn't a single before/after dyno sheet available and a tuner says not to, I'm going to go with no a well.

i had hks cam and adj cam gears on my rb20 and now same in my rb22 - very well respected tuner said leave them both at zero... so i havent had any back to back testing done ...but i take his word for it

Harey McLary made a boo boo.

From what people have been saying in this thread as well as my other similarly titled post...

Cams with stock cam gear settings work the best?

Cam gears will be somewhat beneficial but not as much as just upgrading the shafts themselves.

How does the stroker go up against a similarly modified rb25?

How does the stroker go up against a similarly modified rb25?

pretty close to rb25 with same turbo etc etc either same peak power or a little less (5%) when comparing numbers from the rb25 power threads but obviously a little more laggy but it is also tuned that way for drift on a long open track

my friend runs a very very similar car to mine with stock rb25 375hp though different turbo little more responsive and we are same same around the track even though im a little more laggy i have a few more revs on the other end

... if it were me on an rb20 that isnt a serious track car i wouldnt be putting cams or cam gears on and just throw more at suspension or similar to make a better overall car to pick up where the rb20 lacks a little vs other engines

Man i like your style.

I personally try to go for something different, not to BE different but to enjoy putting my personal touch to things.

Can I ask why you opted to stroke the 20 over swapping in a 25?

I never understood it, for the cost you could get an rb26 and put new pistons and refresh it with basically standard turbos with steel wheels, more power, response and its a 26!

But its a stroker....ooooooooo

Bragging rights yo

but its still less than a stock 25 lol

Yeah no shit aha.

RB26DETT in my gts-t would be phat. I'd hold onto my RWD though...

[snozzle]

does anyone have links to rb26 cam gear tuning threads/articles? I cannot find any?

[bcozican]

i did rb22 because at that stage it was a simplier plan for what i already had done to the car and wasnt chasing big power at first and a little more reliability with brand new engine rather than a 100K old rb25 + the hassle of changing things over

i use it for drift in wa which is a fast long track and suits quiet well now as plans got a bit more aggressive

hence rb26 with twins wouldnt suit and as per above still would be too much messing around to put new gear in

and dont really feel like going the ramp the stock rb25 up to 400hp and swap a new one each season because they break like alot of guys do here..

now, id build a rb25 engine... then buiding a rb22 suited better and still goes hard and keeps up more than fine

you dont have to get it......

you are right I don't have to, because financially and time wise there isn't a single reason why it makes sense.

swapping in a 25 each season would be cheaper, make more power and require less work. Or for the same amount of money and work you did you cold have just build an rb25/26/30 etc in the first place and had the best of both worlds.
