If you want a cheap solution get some DSM 450cc injectors. Get them cleaned and blueprinted. You'll need to hook up a resistor box though. The resistor box goes for like 10 and the injectors you can get for around 50 if you're lucky. http://www.cruzinperformance.com/fuelinj.html Go here to get em cleaned. Cheap and effective. :thumbup: Unless you're trying to get some crazy numbers you'll be good w/ 450cc.
Edit: FYI you will need some sort of fuel management to get them to run...s-afc, hondata, aem ems...etc
