I think I owe YOU the apology- dip into the turbo forum here on TRS, or turboford.org, turborangerforums.com, etc. and do some reading. there's big power to be made with the little 2.3L, with some minor cost investment.
there is debate about the true engine weight of the 2.3 Lima versus the 5.0 Windsor- some sites list each engine as longblock some with accessories such as PS/AC compressor, alt, etc.
Down in the ford 2.3 section, they have the 2.3 pinto turbo engine weight listed as 450#, right below it the turbo coupe 2.3 engine at 380#. 5.0 Windsor at 450#, and the boss 302 same block and heads) as 500#.
