The stock ECU can only handle 2-3 Max
PSI boost, not much but you will feel it.
Stock CR is 9.1:1 not 8.9:1, I found this
out after I did the turbo, I got the same
info as Zaggy has, so it might be a difference
of Japan built and Cami built, I don't know.
Max boost for stock pistons is 5 PSI, because
they are cast, this is the reason I lost the engine
on the way to Moab, I would say get forged pistons
if you want to boost hard, like 10-12 PSI
Also the Turbo 2.3 Ford engines had 10 PSI
waste gates, I don't know how they got away
with that and no intercooler, but they did
Have fun, but Zaggy has good advice, be
carefull, and don't run lean under boost,
Lean + Boost = Boom
