So I had the timing belts done and the mechanic found that one of the "lugs" on the end of the Cam has broken off and jammed into the distributor... ...Lucky for me it means that my car still runs because of the way the distributor locks into the cam... ...however under heavy load I get a little bit of a "chug chug"...

Last time I put my car on a dyno I got close to 150kws at the wheels... ...Which I'm told is quite good for a stock GTS25t...

So not knowing much about Cams... ...If I was to go for some upgraded Cams... ...What should I look for and what kind of power increase could I expect???...

It's also my daily driver so I don't want anything over crazy...

I can only assume that a dowel has broken off the front of the exhaust cam and worked its way into the cam angle sensor.

Very weird but hey, stranger things have happened?!

Just throw stock cams back into it. Unless you plan on doing some serious work to it in the near future, leave it as it is but obviously replace any broken bits.

I have standard RB25DET cams for sale if you need them I guess.

New genuine nissan cams are too expensive could buy some tomei or HKS step 1's for cheaper. Will change your powerband a bit but u get used to it.

second hand set from someone who replaced theirs is the best bet at probably a hundredish

I wouldn't personally consider moving to aftermarkets cams on a motor putting out 150kw....

You could probably pick up a cheap standard cam off the forums here from someone who has upgraded.

It is a bit of a dilemna though, because paying a mechanic to install a standard cam might be a bit of a waste of money (I'm guessing that you won't be doing it yourself).

I suppose the question is how far do you want to go - if you will eventually upgrade your turbo, might as well just do the cams first then?

    • Just had this happen to me too.  R32 GTR.   Also broke "just before going out onto the track" - someone up there is looking out for us... Very scary since I was about to do a narrow street course with zero run-off and curbs everywhere. Many people on here upgrading to billet uprights and R35 bearings?   Or buying new OEM knuckles?  I am not keen to replace with another s/h 30 year old fatigued part.
    • Top off with distilled water and see what happens. If you keep losing coolant then you know to start looking.
    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
