Anything will work as long as you have enough money. There have been LS7 swaps into newer RX7's but i'm not sure about an 87.
The 89 is an s5 and the 87 is an s4 It will fit but might take minor modification.
It depends on how many lugs there are. If they areboth 5 lug than it will fit. If the 87 is 4 lug then you would have to change the hubs to 5 lug.
Yes.
I know an 87 honda accord engine will fit.
Probably not. the 87 should be carb and the 91 should be injected not a good fit w/ the ECU. The electronics are not compatible.
If the engines are the same or are out of the same trim level an easy way to check this is an engine code will be stamped into the bottom of the block if they match its a sure fit, for example D15A2 its a commonly used engine between 84-87 which is a third generation civic. If the engine code matches it will fit right into place and just swap out any other parts needed from the 86 to the 87.
To run, no. To pass emissions, yes.
I have an 87 7mge non turbo and i beat my buddies 89 rx7 with a 13b and webber side drafts
Chevy didn't offer a 350 in an 86 Camaro, but if they did, it would theoretically work in an 87 Caprice.
If you know what you are doing you can put ANY engine that you want in it. Small are BIG block. They will all fit.
Any engine from 1987 and under that year will work.
you could have a bad ground wire that was my problem
