Hi all.
I changed the ina followers on my 2wd saph for replacement new I a followers as the 2 rear exhaust followers were a bit noisy.
After changing them they were still noisy even after giving the car a good run.

Removed the cam cover last night and measured the lobes,journals,follower diameter etc.
The lobes look a little worn but are within tolerance.
The journals on both cams are slightly underside.
The followers measure at 34.91 mm but the ports they go in are 35.30mm iirc so they are out of tolerance but are within tolerance if I go by the standard size qouted in the manual so I'm guessing I have oversize followers and if so I presume instead of the oil filling the follower it's escaping out from between the follower and the port it sits in in the head?

Anybody any idea where to source a set of oversize followers from?

If I replace the cams which I think I will I'm thinking of up rating the inlet to an ab07.
Would this give much power gain?
No idea what my car is producing now,guessed to be between 350-380 but no graph to prove.


Cheers,lee
