HEY GUYS I JUST BOUGHT A 02 C70 WITH A SPUN BEARING<<I HAVE A 06 2.5 LPT ENGINE IN MY GARGAGE THAT I WOULD LIKE TO USE..FIRST I KNOW 01-04 C70 HAVE EXHAUST CVVT AND 06 ENGINE IS DUAL CVVT..HAS ANYONE SWITCHED CAMS FROM LATE 2.3 TO 2.5? NOT SURE IF CAM JOURNALS ARE THE SAME OR NOT.. SO I COULD CHANGE CAM ON 06 INTAKE TO NON CVVT? I HAVENT TORN INTO IT YET BUT I MAY JUST SELL THE 2.5 AND GET A 2.4 T5 ENGINE SINCE IT IS THE SAME ONLY HAVEING EXHAUST VVT

First of all, turn the caps off.

Second, you're a Volvo Tech and asking these questions?

1st thanks for your input

2nd yes i have been a volvo tech for past 6yrs..we rairly get to dig into engine builds..most of our customers would rather put a low mileage engine in it with a warranty..not sure about cam journal size on the heads for 01-04 vrs 05+ which i cant find anywhere at work. Im going to dig into it and find out for sure but i just figured someone on here has done a hybrid type setup

You could swap heads for a bolt on affair, everything else will match up. Plus you could steal the 06 exhaust manifold which is the same as the P2R.

Of course since you're a Volvo tech, I'm sure this came naturally.

well the car has the 2.3 head which i dont think are anywhere close to mating to the 2.5 block(which i could be wrong

also the exhaust mani is gone..but i have one laying here from my old xc90

you not a fan of dealer techs? seem to feel some sort of tension about me being a tech?

i know everything on outside will bolt up but this will be my first mixed matched swap...i know everything i need to know except for the heads which i will figure out i guess when i rip them both apart..

i think the cooling ports are different from what i here but seeing is believing... and not sure about the maching on the front of the head..if they are machined for cvvt on both or if you can put a non cvvt cam in place of the cvvt intake cam

heads are the same, pistons determine compression. VVT cam CANNOT be put into non-VVT head without some work. Search is your friend. Past posts have noted that if you use the head gasket for the block, any head will fit, may just need to drill a small hole in head to match gasket (and I mean one of the very small holes for water, not one of the large water passages.) Thus you should probably use the '02 head with the later block.

I have searched but can't find a def answer.i know the head will bolt on no problem but wasn't sure about combustion chamber sizes per head. I think the 02 and up heads have the modified coolant and oil passages already but I will find out for sure when I tear this engine down..I've read that post a bunch but still had some questions
