Okay so I got a pretty sick red 93 lude down in flordia and brought to ny where I live. Gotta be the cleanest 20 year old car ive ever seen. Wouldn't have got it bc its a h23a1 non vtec but man the deal was so good I couldn't turn it down. Pretty much stock but headers, cold air intake, and full exhaust, and stage 2 racing clutch. Ive been saving up to do a head swap to a jdm h22a. I was also going to get a cam kit that comes with exhaust and intake cams and valve springs and titanium retainers. I was going to have a five angle valve job done. and shave the head. and POSIBLY port and polish the intake. My question is is it hard to go from non vtec to vtec? what needs to be done? do I need to buy a new computer? also what are your ideas on porting and polishing the intake ports on the head? Im not sure about this I know it can be tricky and might just have them polished. Basically I just wanna make power with this head im asking you guys to help me out. Any help is appreciated thank you. I also barely know how to use this lol
