Hi, I have a Y26se engine and I wold like swap to x30xe, but, my engine has low milleage, and used x30 has high milleage, so I thought that use a x30 block, with new rings and bearings and use my heads with new gaskets, how would that be? Compression Ratio?
-
Waste of money, either fit the 3.0 with all the 2.6 electrical (sensors/coil packs/throttle) and call it done. Or if you are determined to spend money, by a crate 3.2 and fit that ;)
Bit of a moot point though, seeing as you're on internet rather than earth, so you won't be able to drive it ::)
-
If you put 2.6 heads on a 3.0, you'll end up with a dangerously high compression ratio, IMHO.
Fit the 3.0 as it is with the 2.6 ancillaries and loom. Mile4age doesn't really trouble these engines.

Daz did this to my cousins 2.6 when the bottom end went , 2.6 head on 3.0 block and it ran sweetly with no ill effects

As Kev sugested above, Daz fitted the 2.6 plenum and other DBW bits to the 3ltr block and ported head from Obi ;)
And yes, it did go very well :D :y

Yeah. And it runs with the 2.6 ECU?

Pull the 2.6, remove the loom throttle body and sensors and fit them all to the 3.0. Fit the 3.0 and call it done.
That's the basics, obviously a cambelt kit would be a good idea. Also double check that the cylinder heads have the two bolt holes for the individual coil packs, post '98 3.0 have them :y

Fixed,, some didn't, the early my2000,, 3.0L didn't.

Fair point... It was done for the Catera going dbw, plus various gm products which had that lump :y
-
Well, finally I have a x30xe. Itīs from vauxhall :) and itīs curious because is from a 98 omega prefacelift but has long intake manifold as my y26se. Any problem with the two holes for the coil packs?
-
The problem would be that they are missing...
Pull a coil pack from the 2.6 and you will be able to compare directly :y
-
I will see it soon then i will start with the swap. I do not think it's hard to adapt, right?
-
You need to know before you start.
-
Do the coil packs need the retaining bolts to give a good earth/0 volt path to the cylinder heads?
If not then the rubber boots will probably stop the coil packs from moving (much) :P

They don't... But I wouldn't chance it...

And can't I put the valve cover from y26 on x30 heads? I remember read some this

You can, and will possibly need to...
The coil pack bolts screw into the head itself.
Remove one of your coil packs, compare and hopefully it will make sense :y

:y I will keep you informed

Another question, my x30xe have the first part exhaust manifold, it will be able to connect with the 2.6 downpipe? Or do I need to mount full exhaust from the head?
-
Use 2.6 manifolds, and 3.0L exhaust system, and downpipes, just grind 5mm off the 3.0L downpipe stub.

:o Pre or facelift?
