2.3 NF block with MC-1 head?

[JShadzi at aol.com]

Yes, the ND turbo kits that I've worked on did, but those kits ran "low boost", the highest stage kit we only ran 10psi with, I suspect with any respectable level of boost up to 20psi a stacked HG just won't hold, a single gasket in a turbo motor barely does.

Ben, there is no advantage to having a 2.3 10:1 motor over say a 2.2 8:1 motor, the lower compression will make more boosted power everytime, you just won't be able to control detonation with 10:1, no way in hell, I don't care what kind of igntion system you have, none of us are Porsche/Audi, and none of us run as "mild" boost levels like the factory cars do, for a street tuner with limited resources low compression is the only way.

It seems like you're trying to find a combination that will work better than the MC 1 or 2 setup, .8l of displacement isn't going to get you that much power over the MC motor you have right now, the NG/NF ain't it.  I suggest keeping the 2.2 that you had built up and focus on getting rid of the CIS to make any amount of real power, that's your biggest bottleneck right now, second the exh. manifold.
