What power and torque increases am i likely to see fitting the above to my 2.5?

Also is fitting just a case of carefully removing them and refitting while leaving the cambelt alone?
p.s i hate cambelts lol

cambelt will need to be removed, takes the 2.5 from 170bhp to around 195/200bhp  

[JonR]

So worth it for the bargain price i have been offered then?

As im stripping the inlet and cam covers of anyway is it much more work to replace the cams?

Best upgrade for the 2.5, makes the engine quite peaky... very worthwhile if you can get it for silly money.

After cam covers, err, all the brackets to the cams need to be removed.

Cambelt cover, cambelt off... drivers side tensionor i think  :-/

another few hours work, but worth it  

[JonR]

Can i use a pattern cambelt kit?

also do i "HAVE" to have a cam locking tool?

Im talking about the cams from the breaker that chris is breaking atm? They will fit and do the job yeah?

Sorry for all the questions but im gob smacked at the power increases lol

I would wait for someone else to confirm, as i am no expect. BUT it think any 3.0 cams fit the 2.5.

Plus i think you only need 2 of the cams, not all 4.

You can re-use your old cambelt, depends how old it is? I assume its not older than 4 years / 40k?

You could get away without using the locking tool, but i would NOT advise it, if your just 2 teeth out, it will affect performance.

[JonR]

old belt is 3 yrs and 2 months and done 12k.

For piece of mind im gonna change it, as its all off i might as well change it, really dont want the hassle of removing everything again,

I'm very friendly with my local dealer and he did say i could borrow a locking tool over a weekend if i needed to.

I would not be happy to refit a cambelt, especially at that age.

Right

1) You should use a new belt kit

2) You need all 4 cams on the X25Xe (XC25XE you only need two)

3) You MUST use the proper timing/locking tools to do the job properly and get the belt tension right.

Hi JonR. I also intend to do a camshaft upgrade during the next few weeks(when I have the time ).It is wise to replace the cambelt and tensioners when it is stripped down,especially if yours is approaching 4 years(mine has just done 37k in 14 months so mine will get done aswell).The general opinion is that you only need to replace the "G" cams as they make the difference,but as it does require a fair ammount of stripping down worth doing the waterpump/cam covers/breathers and as before the cambelt kit.
I have been advised to expect between 18/25 bhp increase and will make the car more punchy in the rev band so we will compare results when the job is done.The work would seem to be about 1 long day so a dry weekend should see it sorted out rairly comfortably.

Never recommended to refit a cambelt, not worth it anyway as if your doing all that work you may as well have the peace of mind of not having to do it again for another 40k/4 years...

You only need to change the centre 2 inlet cams for the power increase, not sure if there is a reason to change the exhaust A cams or not but no real power increase as a result, this will as stated add about 20bhp so take you from 168bhp up to about 190bhp...only way to increase up to full 207bhp of a 3ltr would be to change the block etc but then you may as well just put in a 3ltr engine as its less work lol

Its a straight swap and will fit straight in...

You should change all 4 on the X25Xe......and only 2 on the C25Xe....

[JonR]

is it worth doing then?

will i notice much difference?

ta

[MutantCav]

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

[MutantCav]

ta

Definitely worth doing...20bhp increase will be very noticable
