Rb26 And Cam Gears

[black sky]

Hi Guy's

Now i just spoke to my tuner and he's very reputable and knows his stuff he said that there's no point putting cam gears on standard cam's on the 26 as there is really no gain.

the car i have is an rb26 with R34N1 turbos C106/GT25 A/R 0.60/0.64. full boost at close to 5 grand at 1 bar will these cam gears actually bring that down or not????

i want people who have done it to there car's with the standard cam's to let me know there results.

very very confused because i hear people saying that you get good gains and stuff but now my tuner saying it really doesn't do anything has crushed me.

Cheers

If thats the advice being handed out and especially with R34 N1's on there...

Time to change tuner IMO.

There are a number of threads with before/after/comparo etc to backup the cam gear gives a much meatier mid-range if installed/setup correctly

Hi r31 nismoid

i tried to search for rb26 cam gears on the search function and really didn't get anything can you point me in the right direction on what it is i should type in to get the right results for the question that i'm asking.

Beer Baron posted reults, and has done so a couple of times since then.

there are others aswell but usernames escape me

one line is before cam gears. one line is after. nothing else was touched. now make up your own mind it it's worthwhile or not.

yea i think i might get the cam gears i think.

and that's with just the standard cam's right???

yep, stock cams.

change tuners though dude, seriously.

If they cant get/dont think cam gears give a gain... then its not a good idea to give them a set and tell them to "make the car better" as they obviously wont be able to given the advice.

similar results with the cars we have done with standard cams and turboes etc. Worth doing in my opinion. Even better results with a set on poncams though.

Perhaps time to maybe re-educate your tuner

yea it looks like it's time to reducate him but i don't understand cause this guy is great he alway's tunes my car and know's bout them inside out. i've heared they give gains but after he said they don't i was sort of aprehensive about it. but i'll give them a try i had an rb20 with a gt30 on it so i want better responce than that and with the gtr making full boost at 5000rpm i want it to come down.

these are with N1's with .6 and .64 rears what do you think it'll come down to with the cam gears. what i mean is when do you think i will see full boost???

and do you think it's worth doing the dumps on the turbo's i've heared they really don't make that much of a difference ?? up to 320rwkw on the gtr's

Cheers

any one have any ideas on how much power i cn make with those turbos?? and how much the lag will come down with those cam gears??

Cheers

[Beer Baron]

how much boost is full boost?

i think with the .60 front .64 rear combo N1s you should be able to get to 1 bar before 4500rpm with some smart tuning, some dump pips and some cam gears on stock cams.

Well at the moment full boost is 1 bar but after i change injectors and cam gears full boost will be around 1.3 bar. so any ideas when i'll be seeing full boost?? also

since these are the larger (.6 front and .64 rear) N1 turbos what will be the max power i can get with them??? before it becomes inefficient

Hi, with poncams, dumps and -5 garretts, similar specs to N1's, I reach full boost (17PSI) AT 4000RPM.

Before cam adjustment it was 4300rpm. They were already pretty close from the old engine and that was moving the intake only 2 degrees.

That 300rpm on the road, though, translates into hugely improved spool up when over 3000rpm. Very worthwhile addition to the driving experience

If you have never tried a different tunner how would you know his great??

Seriously if his under the impression cam gears are a waste on a 26 his not worth the coin your paying him!!

Ive got plenty of grphs just like beer barons that can show the same gains, both 25's and 26's.

And Id agree with some nice tunning work there is no reason why 1 bar cant be made by 4 grand.

Will it be ok to leave the adjustable cam gears set to 0 on my rb26 until i get a chance to get it on the dyno when i get the power fc installed?

Can they just be put straight on and driven for say a week set on 0?

[SLIPPERY]

yes cause the car will have the same cam timing as before you put the gears on.

[SLIPPERY]

just dont forget to tighten up the adjustable bolts

Do you know what the final change of the gears were ? for inlet and exuast?

[dano4127]

Would there be similar results on an R32 RB25DE Head (No VCT)

[rev210]

+2 to +4 intake and -4 to -6 exhaust is the normal range for stock cams adjustment gains.

The improvements have a larger magnitude on larger turbos.

There is also throttle response improvements under load, these are certainly felt but, often not mentioned.
