why dont you race gus's mean mini for some cash??? i wonder how gay it will be when that low 13 second minivan walks off with your paycheck.
most turbocharged engines differ from their NA brother in the guts and
heads.
the heads on NA 2.3L fords are heart-shaped in the combustin chamber whereas the turbo head is a "D" port. the raised combustion chamber of the "D" port lowers compression quite a bit. there was a reason for this too. it allowed for the piston to have more "meat" over the wristpin. with a common piston, you simply cut deeper into the relief of the piston to lower compression. it works, but it weakens the ringland. detonate it one time, real well, and you will snap them off!
but anyways, the engine for instance. the engine in my ranger is a NA 2.3L: it has 9.5:1 CR and cast internals.
my SVO *2.3L turbocharged* came stock with 8:1 CR and all forged guts. a neat trick *i mentioned earlier* is the height of the first ringland on the pistons. this thing is thick. it wont fold over nearly as easily as some aftermarket pistons!!! sadly, from looking at a few sets, JEs come to mind...
like demonSVT mentioned, duratecs are getting popular with the small displacement turbo crowd. several members of my home site are installing forged internals for a severely high-boosted application. aluminum blocks were one thing, but the DOHC aspect was another feature that alot of guys are interested in. the heads outflow our stock iron out of the box. some portwork, clean up the combustion chambers, and you have yourself a nifty CFM-moving head.
as for the mopar minivan: dont ever doubt what ingenuity can accomplish. Gus started the wave, and several others now have 12 second daily driven minis. lets say that if a minivan pulled next to me and revved, i would check to see if it was the turbo!
