bro,
i believe 20 valve is a potential engine, of course you got to spend money to mod it. to be frank, i own 3 vtecs before an ef, dc2 and lastly an ek4 of which i spend the most money in modding the car( 2l block, toda c cams, ats ratio, ecu............etc). what do you know, the car really pulls but that was after i spend almost 30k modding it. the moral of the story is always compare a 1.6l against a 1.6l not a 1.8l, 2.0l or a stroker 1.6l thats not fair. i sold all my vtecs now and im having a seg now with 20 valve st with some mod such as programable ecu, racing cams, balanced internal and some mods inside the gearbox. i can tell you that the power that this 20 valve produce can easily tapau my previous dc2( blacktop 180hp with minor mods). Money is the only issue for building a fast 4age 20valve engine......................... :D
