87 REX motor swap, need help
hey everyone, i love my rex and i dont want to get rid of it. I have an 87 dx that had a civic 1500 dx d15a2 carb motor in it..... the timing belt snapped, bents vavles and holes in the piston heads.... I was planning on a motor swap but now i need the help with info= what can i put in here? someone told me either zc from a 86-87 integra or a b16 and head over to hasport with a bag of money for motor mounts. I dont have a lot of cash at the moment so im look at a motor/trannie for around 400-1200. heres another problem, i live in maui HI and motors are kinda difficult to come by, its around 300 to ship in from cali, which i would like to avoid, but i'll do if possible. could i drop an si mootor from a 88-95 hatch, copue, or sedan (civics)? the carb motor had around 60 HP and I would like a good 110-130 HP in there. a lot of people are telling to sell the 87 rex and buy a 88 and up. I kinda dont want to because you really dont see that many hooked up 87 body style rex's out here.... I need input, all you honda heads.... please help out a newbie to swapping. thankx for looking also.

If you want more power, I would throw another carbed 1.5 in there and put a bigger carburator on there.
If you choose to put a Fuel injected motor in there, you will basically have to re-do the entire fuel system, which will be a major pain in the ass.
I personally want to get a 86-87 crx si

the fuel system swap i dont mind at all and i want to boost like a mad man in such a lite car. i did day dream about h22's with t3/tbo4e's in that little rex... i know i know major fabrication. Would there actually be a performance incrase with a bigger carb? I thought about edlebroke, but i really want a fuel injected setup. i know i can nos the carb.... but grrrr, it would be nice to have a fuel injected setup. I know i can find piston heads for around 50 and valves for aournd 50 - 80... but boosted fuel injection=i want 1....

heres another thing that has me curious, the d15a2 motor i have is a 1.5 84 to 87 block = the piston heads are 74mm........ the 88 + dseries block have 75mm piston heads.... so would i still be able to swap in a 88 + head into this 87 block?
