well, that is shitty about ur car. but unless u want to spend more money the del sol engine wont go into ur car, its a different obd and u will waist to much time putting it in ur car. for 400-700 id go ZC swap. 130hp DOHC, alot of people will say get a SOHC Vtec, dont they are retarded. drive in a ZC car then drive in a SOHC Vtec and the ZC will stomp it anyday. ZC is also super easy to install. its like taking out ur d16 and putting it back in, its all plug and play, u gotta switch 3 wires only, well play with the pins. theres alot of websights that tell u how to do this. u can also use stock Si tranny and everything stock. u can use stock Si ecu, but a 89 integra will make the car feel 100% faster. its like night and day when u use the 2 ecu's. the engine will run 300-400 bucks with like 100 bucks for ECU at a wrecker. Then get some oil and odds and end and ull pay around 600-700 right in ur price range. about the clutch, it would b wise to swap in the clutch with the engine out, less clutter, no need to get anything super good like act, u wont have enough power really, so get a stock Si clutch. i ran the shit outa mine until i got my swap and it held up great or get a little better and not have to worry about it. But a ZC, if u get i/h/e and cams u will b in the 14's which is damn good for a lightly modified non-vtec 1.6L
