the dizzy and the water housings for the 16v are fine to use as they are on the fwd... even those longer ones at the back of the head.. where as the 20v needs the firewall modification for the dizzy, and the water housing at the back of the head.. or DLI converter.. and milled billet ally housing.. Ant does kits for this i belive.. but no where near as easy as 16v...
ae86 slide.. tru yes it is tru that the 20v is a better $ for hp investment.. as far as you need not to modify it much to whip 16v's...
but what i was meaning was that i would much preffer a rebuilt 16v, that you are establishing the history on.. rather than some young punk in japan, who never services his car, writes it off, and you get his front cut.. looks good on the outside.. but you have no idea about the engine history etc.. and as i mentioned... lack of matenance is a huge killer on the modern high strung 4 bangers....
