Title: 2.6 or 3.2 manifolds onto 98 2.5??
Post by: PhilCavSRi130 on 28 December 2012, 23:17:51

As per the title guys, are they a straight swap over? I guess gaskets to match are required but is there anything else i need to look at?

Ta  ;D

3.0 cams or drop a 3.0 lump in, going long way round to get more noticed power....

Got the 3ltr cams to go in with a cambelt change shortly so was thinking of doing these at the same time if they're worth changing? I've already got sport cats, powerflow exhaust, so the manifolds seem to be the last weak point.

Ok good  :y

3.0 inlet and lower inlet to with cams?

Maybe 3.0 brain to, if omega it is your fitting to, better top end i'm told....

You'll have to do something with the EGR feed from the 3.0 manifolds though ....... 2.6/3.2 doesn't use an EGR

Need to mod them slightly to get the 2.5/3.0 cats to fit, so not quite a straight swap. IIRC, its about 5mm to come off the end.

SAI and EGR need blocking.
