Not all v8's are heavy ever look into using the LS1 (my fav engine hehe) not sure on the exact weight but i know it weighs exactly 30 lbs lighter then the 240sx 4 cylinder engine. Take a look at this guy from ls1tech not only put an ls1 in a conquest turboed it on top of that. http://ls1tech.com/forums/showthread.php?t...hlight=conquest And as far as having no room to work on the engine. if u look at the engine bay pic of that car then a stock camaro or firebird conquest has more room! lol O and the engine isnt gonna be halfway under the dahm windshield cowl like on my TA only thing i hate bout my Trans Am [/endrant]
