well in my rant, i was kinda stating that there is a border around 250. at that point, your car is no longer just a DD, its a full on project. good bolt ons; small turbo kit; big shot nitrous will yeild around 250fhp in our f23 engines.
now if you planned on dropping 15k into an engine/tranny/suspension or wantedto make 400whp.... then you might as well get a DOHC engine for easier and cheaper parts. there is only a select few us that are willing to push our family cars beyond the life they were meant for. you, Stinker, Drift, Egi7, Darkside, pirateMcFred, NotoriousB and myself are apart of that group.
f23 parts: f22 valvetrain; k20 pistons; f23 rods. << custom
h22 & h23: there own parts. <<< plenty of ppl making parts
