2.5l MC

[Ken Keith]

Let's say I was to purchase a 2.5 liter short block from Eurospec, 
and use it with the rest of my '88 5kcstq motor.  

I was wondering if it were possible to, or rather what would it take 
to, convert the motor to dual knock sensor configuration, using 
parts from a later model MC.  Is it a complete swap, requiring the 
wiring harness and ecu (I assume ecu, that would be a MAC14, 
right, and I have a MAC11?)

I thought that since the motor would be 8.5:1 c/r, that it might be 
better to have an engine management system that is supposed to 
be dealing with the higher compression.  Is it even a problem?

Perhaps the J&S Safeguard knock sensor would be another 
solution to the same concern.  Is there anyone on this list using 
that device?  I saw on http://www.miata.net, in the forced induction 
classifieds (why can't we have one of these, so chock full of used 
turbo and supercharger kits!), someone sold a used J&S unit.

Comments welcome.

Later,

Ken
