Hi or low comp???

I have a spare Z7W engine that i got from Lee.
The main reason i was thinking of interchanging was because of the valves!

If i could use the Z7W as it is then that would be fine by me.
I take it this means i could use the standard oil pump??

Ah, so its not a complete engine. OK.

Nope not a complete engine.

By building the new engine i want to try and iron out any tuning probs you guys have come across,(i.e manifolds),so that if i want i can later upgrade easier.Does that make sense?

The cheapest way for me to go would be to fit my turbo to the Z7W as you have said.
If i go the supercharger route then this will irradicate the manifold business,(by fitting your 3 into 1 manifolds etc),and then give me the better power delivery that i prefer.
Also the scope to go further with the tune if i desired.
