i plan on buying a 2nd gen crx si from either 90 or 91. I will be doing a engine swap for it. not sure what ones but i do know it has to be dohc vtec. many say b18c1 or the b16b jdm or the k24a2 or k20a k20a2 k20a3 etc. what would i need to do to have one of these engine put into a crx if they even can. also i read in other forums saying how these engine cost upards of 4000-7000 dollars but on ebay they have them for dirt cheap please explain. http://www.ebay.com/itm/JDM-Honda-Acura-K20A-2-0L-DOHC-i-VTEC-Accord-TSX-Element-Engine-K24A-2-4L-/281797485158?hash=item419c706266&vxp=mtrhttp://www.ebay.com/itm/JDM-Honda-B18C-DOHC-VTEC-Engine-Longblock-Integra-GSR-B18C1-/171935034152?hash=item2808206b28&vxp=mtrhttp://www.ebay.com/itm/98-02-HONDA-ACCORD-97-01-HONDA-PRELUDE-2-3L-BLUE-TOP-DOHC-VTEC-ENGINE-JDM-H23A-/281710446463?hash=item419740477f&vxp=mtr. also one more thing ive hear 50/50 split from people. should you drive a stock crx si on premium or unleaded. is it required. also any tips on what to look for in a crx si and what to do first in the build. i do want it to be a street car but fast. Only care about acceleration and speed nothing else just wanna be pinned back into my seat when driving.

 

Google. There are like 6 websites dedicated to 4th gen hondas, CRXs, K20s, etc etc. And go to Hmotorsonline instead of eBay. They have a better reputation.
