As Mark says then lol Whats the reason Mark?? Dont doubt you for a second but always nice to know why

The C25XE cam with the more aggressive exhaust cam fitted as standard (same as teh 3.0 one), when the X25XE was released the exhaust cam changed to help low down torque so you need to change both on the X25XE to get full effect

[MutantCav]

Well I never! I thought the A cams on the X25XE and the X30XE were the same...learn something new every day

[cem_devecioglu]

What are the part numbers for inlet and exhaust Cams.. ?

And also is there any important issue that must be taken care when changing the cams..?

[MutantCav]

When upgrading the cams the increase in torque will be too much for the AR25 gearbox so gearbox should be upgraded at the same time really...or will need doing not long after when the old one dies!

so tco will be 4 cams + ar35 .. too much for an upgrade

[MutantCav]

Should be able to pick up the 4 cams and gearbox for about £200...if you can do the work yourself then its not too bad

unfortunately ar35 even second hand is really expensive here..  :-/

Gearbox is not neccassary, the increase in Torque is not massive.

Check the cam identification info in the maintenance guides, its shows what cams were fitted to what.

Shut up Chris you know nothing lol I thought it shortened the boxes life...but clearly not that significantly...as Mark says (again!) lol

Its the diesels that dont stand the tuning but, the boxes are right on the edge of thier rating in normal tune anyway.

Remember boxes are only really bothered by torque and not Bhp.

Thanks for the info

Been reading with interest the additional comments.Thanks for clearing the issues up Mark,so we are now safe to "pulg,n,play"..well almost.

I might as well change the oil cooler while in the middle of the V.

Wise move?

[amba]

Wise move if it is giving problems like oil in header tank or water leaks,but what started as an upgrade is now turning into "if it moves replace it " and will work out quite pricey interms of parts alone.Well worth the cost of the water pump change at every other cambelt but oil cooler is fairly major if nothing causing problems.

[JonR]

Dirty mucky brown coolant, can get cooler For 80 tokens.

tbh I am going to keep it So might as well, and I paid peanuts for the car
