rb26 cams in rb20 with standard ECU works!

[FLY-SKY]

so would standard 32 gtr cams work? or will only vspec cams work?

[Sydneykid]

I have used R32 GTR, R33 GTR, R33 GTR N1 and very shortly I will be sticking a set of R34 GTR cams in an RB20. I have not noticed much difference between the different models, if any.

So, firstly, Hi, new to the forum/site.

I am currently a member of the SkylineOwners club in the uk.

A few of us have been interested by your GT-R Cam experiences.

Basically, we would like to know.

Does it actually work? There seems to be fors and againsts in this very thread

IF it does work or for you only, what is the cookbook for it.

for instance, What else do you need to have to get them to run properley?

Cheers Folks,

Alex

Stay tuned whilst us convicts get it sorted, they are coming out of my car today so its easier to find the fault with the car.... if all goes to plan and the car gets tuned, then i will then throw them back in and see if A) my current prob returns, & B) can be easily tuned around C) they make any more power

Hopefully there is some definitive answers soon. My cefiro lands in 5 weeks and I want to put GTR cams in whilst I change the timing belt... so if I have to get specific BNR series Cams Im hoping this thread will reveal which ones it is. I will hopefully be adding in GTR injectors aswell so I will get a decent tune at the same time as my mate does alot of ECU stuff (makes a heap of Nissan Daughterboards for ECUs and chips S13, Z32, R3x etc etc).

Oops just another note so I can subscribe to the thread

Lol, not still bitter about that eh guys?

Aside from the humour , much appreciate are the efforts you guys have been making over this

It will at least let me know if I can ask a premium for my old Cam's so I can get nice uprated ones

sorry for digging up an old thread, but i have the opportunity to get some 33 GTR cams at a decent price. I have a redtop ECCS rb20det in my R31 gts-x and after reading a couple of threads like this im finding it hard to come to any conclusion. I would be purchasing them now, but only fitting them with aftermarket cam gears after bigger turbo and fmic goes in. Im after better response, low down torque and higher power generally throughout mid-high rev range.

Any thoughts here?

[ylwgtr2]

i will add that R34 cams have a diffrent crank angle sensor drive.....

if everyone pulled their finger out of their arse and tried it then more people will be able to tell you of the results. do it, try it, tell us how you go. i'm sick of the armchair tuners not having a real go.

so far 2 people tried it at home and failed. I tried it at the mechanics and it worked fine. at least Roy and BBenny had a go and i'm sure they will get it working eventually as they are actually doing it rather than just talking about it...

Roy had some mechanical/tribological issues when the cams were fitted. I have the head and cams and I'm waiting for an opportunity to determine the root cause of the problem. Until then I'll leave it to Roy to discuss the result but I would suggest at this stage getting any cams intended for install checked by an engine reconditioner before installation.

Looking at how tha cam has galled with the alloy in the head and seized, ill put a case of beer on bent inlet cam. Its the onlt thing that makes sense....other then the cam diam being a few thou out changing the tolerance in the journal. The most damaged cap happens to be the cap that was relpaced during installation...silly question, will having the front 6 caps evenly torqued up with no no.7 bearing cap installed bother the cam.

For 7 days it would have undergone bending forces as the very end of the cam was not bolted into the head.... i doubt the valve springs would have exerted suffecient a force to load the cam beyond its elastic region....who knows?

will having the front 6 caps evenly torqued up with no no.7 bearing cap installed bother the cam.  

I have seen and laughed at a few stories where cams have been snapped while being installed, where they have not been torqued down in sequence, but put in front- to- back. The pressure on the lobes on the cam would appear to have sufficient force to snap it, I wouldn't doubt it could "merely" bend them instead.

[Roy]

...I wouldn't doubt it could "merely" bend them instead.

The snapping thing and the no.7 bearing cap damage tells me the cam is bent and its bent because the front 6 caps were torqued evenly but no.7 left off until i could find a relacement.... the load onth ecam increses the longer the lenght of unsupported cam so sould have though with having no.6 in place it would not have been a problem...oh well.

Got any RB25/RB20 cams laying around Mr Parts Supplier? RB26 with sane lift?

[DoughBoy]

How long did you leave it to bake in the oven while you got a replacement?

Yeah have got some new cams in, but not talking to you until you get your car back on the road (or know what you want to do)!

[Roy]

How am i supposed to know what i want to do until you do??? You aint my daddy...are you?

Roy I have 2 NA cams I can loan you if req.

LOL...sadly i do as well because i was recently mistakingly supplied an NA head which resulted in a rather high compression turbo engine. Looking at the specs idont think the NA cams woul do much...i need some 260 / 8.5mm cams.

After that the R32 isnt going to be touched, all my spare cash will be spent on a MK I Escort
