Keith,

I dont know about the RB25, but I do know that you have to shim the cams on the RB26. I installed my own injectors and clutch as well. But you are braver than I am, I cant afford a new set of cams, plus a head if I screw it up.

The RB26 has solid lifters where the RB25 has hydraulic lifters so wont need shimming, i had my cam and cambelt changed by norris designs and took them just over an hour ish.

why should you ignore doing the cams?? they are an important part of the engine and make a big difference

I've got both on my car and found both as good as each other.

I def noticed a difference when the cam was fitted, but it did need a remap anyways.

The water injection is brilliant for track and very hot days, it keeps the charge temps right down and on a hot day the car goes like a cold morning.

there will be a specific method for tightening them down,if you tighten one end too muh you could potentialy snap the cam,tis not hard to do though

You can't go wrong really mate, as they are a direct swap.
I would download the r33 engine manual as it gives the tightening procedure and torque settings for the cam carriers.:bigthumb:

Just a quick thought, did you get the right pon cams for your car.
They are different for the s1 and s2 engines, so i'm told.

I have fitted an inlet (same as Bruce's) and just follow the manual, it is pretty easy just take your time and don't swap the caps about either. yep series 1 and 2 are different because of different CAS fitting in the exhaust cam I believe.
