if your ultimate goal is around 250...then doing the other stuff now
will largely get in the way later when boosted...
meaning higher compression pistons and the like will be money wasted and
spent again later to garner lower compression etc...
if your aim is to go 200 asap then ya might need to but to what end...its not
going to break any records...and stock you can run 170's to 190's all day everyday...
and get to the most valuable return...experience running on the salt....
and by waiting you will then acquire the turbo system at a significant discount
because between now and then the bits and or the whole system will be found....very
economically....
