If you upgrade the camshafts on a 2.6 V6 to the 3.2 camshafts is it just a straight swap or do other bits need changing too??

I've heard you can gain quite a bit more power doing this but is it as straight forward as it sounds.

[Kevin Wood]

Cams are a straight swap. Will need new cam cover gaskets while you're at it. Intake divider and manifold can also be changed as they are slightly larger on the 3.2.

Might as well change the cam belt and tensioners while you're there.

I may be wrong but I believe 3.0 cams would do the same job. Might make it easier to find a set?

Thats great, thanks for your reply, i'm gonna be doing the cam belt and pulleys soon so i think i'll do this at the same time. 

Any idea what the effect will be on fuel consumption?

I know I gained 12 horsepower by putting back 2.6 cams in repacement of the 3.0 cams in mine !

I might be being a bit thick here, but do you mean you put 3.0 cams in a 2.6 engine and gained HP? :-/

hi all sorry to butt in but can i ask about cams as well i believe i can put in 3.0's in my 2.5 ? and where would be best place to find replacement cams etc many thanks

You must have had some other fault!

[DodgeyDave]

I've heard you can get up to +25hp by putting 3.2 cams in a 2.6. I'm gonna do my cam belt soon with the help of the forum DVD so i was thinking about doing this at the same time while i have it in bits.

I justy want to know if all i do is take the old cams out and put the 3.0/3.2 ones in?? or if i NEED to change anything else :-/

Yes, and try one of the breakers on here.  Wise to put on a 3.0l divider plate as well

Best place to source the parts from a 3.0 would be to find someone who's breaking one or go down the scrap yard and see what they have. I believe they used the 3.2 litre engines in Isuzu's aswell

Make sure you have a proper locking kit

[humbucker]

as The Boy says, if fitting 3.0 cams its worth fitting a 3.0 inlet divider too. you could always port the openings on the 2.5 heads too as i found them to be slightly smaller than the 3.0 (pic of my c25xe with 3.0 inlet divider below)

[brian36]

thanks for your help and sorry for butting in will speak nicely to members on scottish meet if any of them can help,im a complete numpty when fixing things.
many thanks again

I bought a 2.6 that already had 3.0 cams in it.

did a before and after dyno check to find that I'd picked up horsepower when I went back to the original cams.

I'm actually planning to test the theory once-and-for-all soon.
