Hey guys i just got an 88 rx7 gl, and i want to put the engine thats in it into my 86 rx7. But i want to put everything that the 88 has including manifold and everything. Now i want to know will it fit in my 86??????? i dont want to try all that and it dont fit, am my 86 had a gas leak will it be there after a swap the engines?????

 

yes it will fit, and yes the gas leak will still be there unless you fix it

everything will fit

 

Since the '86 and '88 are both Series 4 ('86-'88) everything should be almost exactly the same. BUT, do a search for 'injector impedance' and read up on it before you get started.

 

but the gas leak that it has is like a gas leak into the motor or something like that. how do i take kare to that??

 

the leak on teh engine is probably a faulty fuel line, pulsation damper, or injector grommet. replacint the engine may fix the leak but you should look into replacing all vacuum lines, fuel liness, have the injectors cleaned and flow tested, replace all belts and hoses plugs, and applicaple gaskets before installing the new engine into the 86. IMO, a fuel leak is far eaiser to fix than an engine replacement. if you are not mechanically inclined to fix the fuel leak, how do you plan on replacing the engine? you may be opening a new can of worms. fix your fuel leak before looking into replacing the engine.

 

Thanks bro, oh na am not replacing it myself someone is doing it for me but i like to do some homework on my things before i take someones time. So yea am going to do that replace all the hoses and all that b4 i pay for the swap, hey can i use the sparkplugs that my 86 has and put them into the 88??? because those sparkplugs are brand new.

 

yup, the plugs for the 86 will fit in the 88. they are identical. using NGK plugs correct?

 

Use the harnesses & fuel injectors from the '86 engine to avoid resistance problems.

 

so ur saying use the ones from my 86 even if the engine is no good cuz it keeps over heating??

 

thats correct. use the 86 injectors on the 88 engine.

 

ight thanks guys. today i have the guy come check it out to see when kan he swap the engines and all that... how much do you guys think is a fair prize to pay him, am not saying am cheap or anything i just dont want him to try to rip me off.

 

No idea what hourly rate you would agree on, but pulling an engine, then replacing it is about an 8 hour job for someone with experience and 1-2 people to help maneuver things around. That's if he will be disconnecting everything, then reconnecting it on the new engine.

 

ohhh ok, so your saying this is a one day job??? if u know of anyone in ocala florida thats good let me know because am still looking for someone to do the job. i had a guy for it but i dont know he keeps procasinating am not going to force him to do the job. and i dont think a shop would shop me a fair prize lol, i bought the kar running for 700 i dont want to pay more then what i pay for the car lol.

 

do you have the proper tools? if so, why not try it yourself. you'd learn a lot and we're always here to help.
