Paul, I rpelaced mine a few months back. The part is about £40-£50, plus a few hours labour. but there is also a tensioner that MAY need replacing whihc is around £90.
I had the garage to it at the time as I couldn't spare any time, came to just under £200 for everything.
The air-con etc makes it sometimes difficult to get at apparently.

If you go to: http://www.unigraph-design.com/mimms/service_manual/ and download the 4g2turbo overhaul manual, section 13 tells you how to do it.

Hope that helps,
PS: how many mile shave you got on the car now ?

Thanks

You need specail tools to set the belt tensioner, and it's worth doing right as it could cost more in the long run.

I had my belt replaced for 230 AUS dollars.
I can do things myself but decided that it wasn't worth it.
Even if your belt didnt snap you may still have bent valves in the head as the cams may have spun. You might wanna get this checked.

When the engine originally stopped, I take it that it stopped itself and it wasn't you switching off the ignition?

If you take off the cam cover you may be able to see if any valves are not returning back to their seated position by checking the valve clearances. If a valve is bent it may have 1mm or over gap (usually a lot more!!).

I've fitted EVO 1 timing belts before so I can comment first hand if you need any help.

That sounds pretty terminal then :(

I would normally leave on the manifolds (inc turbo) when taking off the head just for convenience. Once on a bench you can then remove those if required.

Are you up to replacing valves / insert yourself? Valves are easy to replace but inserts (if cracked) require freezing to fit. I hope any damage you find is minimal.

Good luck.

l will hopefully be able to finish removing head over w/e i dont think ill try to do valves or guides il take it to Dragon fingers crossed. if??? its only a couple of valves , why its apart is there any thing else ie gas flowing that can be done not herd much regarding any head work on evos also would uprated head bolts or gasket be worth it?

The only type of gas flow I would attempt without thorough research would be to align the ports on the head perfectly with the gaskets and manifolds. Mass production doesn't lend itself to perfect alignment.

You can smooth off any casting lines left by the mold cores used for the head ports and manifolds and generally 'polish' these surfaces.

Anything beyond the above and you'll need to be paying for the port work to be done. The shape and routing of the ports are often more important than the actual size (bigger is not always better).

If I was in your shoes I would just align the ports and be happy with that. The standard car isn't exactly slow.

Cheers,

Mark
