I was just thinking about this, seen a few mentions. I was interested to know what would be required to graft the C20XE head onto the X20XEV bottom end. If it's not possible this will be a swift answer.

I know I could swap the engine as a whole, but let me say why I wouldn't.

1) Car is an Auto and I want it to remain so
2) I have nowhere to do this other than the car park near my flat.
3) Though I've recon'd a head on an X20XEV whipping a complete engine out is something I really feel I couldn't do on my own.

Car has air-con, I would not consider anything if I can't keep that, so again possibly a swift answer. Also, can this be done carefully without disturbing pipework (therefore not dis-charging the system).

So treating me like a complete idiot, what would need to be done.
Cooling, considering I'd want to keep air-con so wouldn't want to swap existing radiator setup, and additionally it's an auto so has an integrated oil-cooler in the radiator.
Exhaust manifold
Inlet Manifold
Fuelling, any changes which would not be covered with replacing the Inlet
Clocks
Electrics, fairly confident in this area (one of the few areas I am!).
Any difference between dis-pack and coil pack (in terms of suitability)
 
No it seems pretty perfect, just a potential future project. Had a minor and I say minor problem yesterday, at some traffic lights with foot on brake and in drive I could feel the car pulling. So I stuck it in neutral and the revs rose to about 2K, then dropped to 1K ish. Then the car died. Started up again and not a problem. I'll clean the Idle Valve when it's dry and I've got a blank piece of the EGR coming, so I'll see after that. It was the first long run it's had since I got it back on the road. Did about 150 miles on all types of roads yesterday and apart from that it was faultless. Going to Bristol tomorrow morning to collect my SRi Twin Spokes and a couple of other things so will probably do around 250-300 miles. If that all goes well I'll be really happy with it for now.
 
pistons are different but not sure if they would need to be changed?
 
iirc you can do it but there's something you need to do with the oil pipe or something ???
 
I'm going to do the head and gaskets in the spring and maybe fit some cams, but for less than the price of the cams I can get a whole XE let alone just a head and bits etc.

It'll just be a bit different
 
to me its a silly idea. Personally if you want to play with the XEV stick some cams in (£200 from Courtney the ones i had) and it will transform the engine.
 
An XE will mate up to your autobox no problem, and I'm sure there will be a torque converter that will fit it. They can run air-con compressors too, might need to change it's pulley though.
 
Tbh there ain't a great deal of difference performance wise in the 2 engines, and you'll always be restricted if you have an autospastic box.

4 branch manifold, and cams and you'll be running more ponies then a standard XE
 
I saw your previous post and I was just thinking to myself, do I know what I'm getting. As I'm going to strip down and essentially refurbish in the spring, then why not keep what I've got. Is the manifold worthwhile then?
 
anythings worth while if your going to add to it, imo theres no point just sticking a set of cams in it for the sake of it, if your looking to get any decent gain out of stuff like that then better start saving as it wont be cheap and will need more than just cams to see a good gain, as well as some stand alone management, but youll still be stuck with an auto box so kinda defeats the purpose
 
Yeah the Manifold is worthwhile, I think the standard cast one restricts the XEV to an extent, and I wish I had replaced mine!! if your XEV is good there's no point in changing it for an XE, I'd only change it if I was v6ing or turboing it tbh,but regardless your never gonna set the road on fire in an auto tbh
 
All these auto bashers!! Was just thinking of trying something a bit different. Might look at cams/manifold if they come up cheap enough. Got a couple of months to keep an eye out for them as I won't be ripping the head off until the spring. Maybe during the royal wedding, lots of time and peace and quiet! Lots of Bank Holidays together then!

Interesting, where in range is the improvement?

Not a lot a lower reves, but from about 1500 nice smooth ramp up. Rolling road maps attached. The first was bog standard engine, the second was with Superchip added and the cams , with engine reprogrammed. As you can see it's gone from 131 bhp to 164 bhp @ 6600 rpm, and 127 lbft to 140 lbft. Not bad considering only other mod was a K&N panel filter.

bloody hell thats some increase
 
Roger,was this without your 4 branch manifold and exhaust system fitted then?

Thanks.Lee.
