Depends if you need your 100k service or not, or else I'd just do the pump. Read somewhere that cam gears on RB25 don't do much compared to 26
And yeah, I went to racepace for them to do the work - I got parts from Kudos (cheapest and tomei cam gears ftw.)
Cam gears
Bearings & seals
Belt
Water pump (just went stock one)
Fuel filter
And then they had to replace rear rotors and pads and they fixed a few other things up replaced oil on everything.. got a invoice somewhere be prepared to have a little more spare if your going in for a service but looking at 1k ish for just the engine stuff.. everything has to come out.
My invoice was 2k, but that was everything down to the windscreen blades, and slotted rotors / race pads obviously racepace are a bit more pricey than some places but they sure do know what they are doing. And local for me.
Going to Trent for my tune though, bit cheaper and considering he is JUST primarily a tuner and only heard good things I believe the car will be in good hands.
Forgot to mention, Chris at racepace called me often for updates which was great - rather than just doing the work and hitting you with the bill afterwards and didn't mind talking about options over the phone.
Edit: I went HKS cam gears at first but after talking to tuners apparently not the best because they only have 3 bolts and can possibly come lose and there goes your engine, whereas Tomei have 5 bolts - go the Tomeis.
