Water injection / meth installed properly is excellent and you will achieve good results just be wary off using meth in the wrong hands and the wrong install it's dangerous

Made a start stripping it down to a bare shell today!!

Going to start with a few welding jobs on the shell and a proper roll cage first.. I think it's basically a fancy show cage at the moment that will be going on eBay.

Then worry about everything else

Does anybody know if DVA power still offer thier own solid inlet camshaft for the VVC head that works with the Piper blanking kits and an offset dowel?.. I certain i have seen this mentioned before

Never known Dave to do a solid inlet cam for VVC, he deals with Piper mostly, think years ago he did some sort of conversion that allowed you to use standard MPi cams in a VVC head.

It's post 6 on this this thread that has given me the idea

http://forums.mg-rover.org/mg-r-modi...t-cams-499106/

It was been mentioned about locking the vvc mech.. but my vvc mech is shot from swarf but the old engine died ! so its getting binned

I don't want the vvc head for mad cams, a pair of say 135 or vvc exhaust cams would be suitable if they fit.. its the CFN flow over the MPI head that i need for my big turbo.. Or so I'm told?? but does cam duration have a factor in that aswell?

So tonight head off and engine out in just over an hour with having to touch the gearbox or driveshafts

This will also allow me to finally finish my 2 piece driveshaft with centre bearing

A pair of VVC exhaust cams won't work either as it's just the inlet that has the enlarged journals and the exhaust side has regular sized journals.
In my head cam duration will help, if the valve is open longer then there's more time to move air in/out of the chamber, likewise more lift will help too.
Using a VVC head will definitely be a benefit but unfortunately it can be expensive to convert to solid cam.

I've been in contact with Dave Andrews over this.. he is on Holiday at the moment but has given me a few ideas.. mentioned a 633 profile cam.

Another option that has been mentioned. is porting and polishing my current head then add the 135 cams to that..

I know in theory the boost could just be wound up higher on the standard head but would like to keep it sensible

Yes, a 633 is somewhere between a BP270 and the 285 I use, would be a nice cam for use with a turbo!
If your going to order a set of cams then it's simple enough to order a cam to suit your VVC head.
The only reason it's usually cheaper to use an MPi head is that used cams are more available 2nd hand and you don't need the blanking kit.

I kept the 2 piece shaft from MG ZT donor car, with a small amount of work to the subframe the bearing mount will fit straight on.

Just thinking 2 piece shaft, my quiafe diff, new suspension + bushes and finally corner weighing should give it a chance of driving in a straight line under boost!

I soon realised that decent geometry was good enough to get me pointing straight and that if I had corner weights done then it would be perfect and there was no need for the other shaft.
