85 SEI a20 swap.

[Christofur]

so i bought a a20a3 from the yard today
Pics:





it came with no throttle body or a distributor. no flywheel but when i have been reading on here im going to want to use my on my ES3(right)


so now what different types of throttle body's can i or should i use since i have to but one anyways.

as far as the distributor well 2genguy you might have to help me out with the megajolt set up.

also i have a question about manual steering. is the only thing i need is the manual steering rack or is there more to it then just that.

LOTS of throttle bodies work. Pretty much any B series and a few D-series throttles will fit on that manifold no problem.

Since you're keeping the ES wiring harness, you should be just fine bolting your ES distributor right onto it. Use your ES flywheel/clutch/transmission, all should bolt onto the A20.

If you're using all the stock components, don't bother with the MegaJolt. I'm not sure if the stock ECU would freak out not having a distributor there... There's probably going to be a bunch of little things that won't connect up right. Be prepared to do a little wiring. Might pick up an 88 Prelude service manual, and the 85 Accord manual in case you run into an unknown component and need to figure out where it goes or connects. If you want some help again, I can come up.

Also, really random running into you up in Auburn, but I guess you live just right there. So, it's probably not that weird. Just good timing.

Could you use your current intake manifold?

ok i was hoping my distributor would work.

then only thing i might have trouble is the getting it running part.

when i say the lotus i was like i wonder if thats john.....nnnaaahh then bam you pull up.

[Christofur]

im hoping to use it and just put on a new throttle body.

i just don't know how big to go.

[2ndGenGuy]

The ES intake manifold will not swap to the A20. The ES head uses circular ports, while the A20 uses the oval ports. This is the only caveat with this engine swap. The oval ports are way bigger and can flow more to the valves, hence the extra 20hp.

Ah this sucks. I just checked the parts diagram and the ports are indeed rounder

I was asking this because the easiest route would be to use the ES wiring harness and use an 86-87 EFI computer. It can still be done tough but I'd use an 86-87 Intake mani.

[Christofur]

i thought you meant on the a20.

I might just buy this throttle body off this guy

i was looking at my ES wiring harness and the one on the a20 and they are almost the identical.


so does anyone know about power steering to manual steering? is it just buy a manual rack and install?

[Christofur]

well today i took off the bottom pulley and where the pulley slides on its cracked. so going back tomorrow to get another motor.

[carotman]

The crankshaft is cracked?

[Christofur]

where the bottom pulley slides on the motor. right next to the woodruff key its broke

they glued the pulled on so it would stay....

I'm sorry to hear that. Do you want me to send Tony over to break somebody’s legs?

[carotman]

Do you have any pictures of this? It's probably repairable

[Christofur]

well its still under warranty so ill let them deal with it and get another one.

[Ichiban]

I've got a sweetheart motor with 160KM on it, it's a BT that I got years ago when I was gonna A20 swap my car. It came with the entire wiring harness and computer. Shame you had to deal with this, I woulda given you that motor for what I paid for it.



It's in Castlegar BC, inside a garage. Covered in dust and likely beer cans, but otherwise should be flawless.

they ended up by giving me a BT. only thing i need is the throttle body. i bought one off an 89 accord but its doesn't match up to the BT intake. so i might just go get the intake mani off the 89 at the yard.

I've also got both a BT intake manifold complete as well as a complete dual runner intake. Just so you know, see what the junkyard says. I'd prefer to get rid of the A20A3 dual runner intake. Has injectors, everything.

[Christofur]

I was at pick n pull and found a TB.
I changed the water pump, oil pump seal, oil pan seal, timing belt, valve cover seal and i still need to clean it before it goes in =>.
so its pretty much ready to be put in. I'm planing on taking my ES motor out on Saturday hopefully Washington weather is nice to me.

[Christofur]

well i got it in a running just one Major issue.

when i go to drive it, it sputters and back fires some.
im using my SEI dist. and ECu idk if that would have anything to do with it.

Fixed Running good Just cant get it to idle right. does the idle bounce

[Christofur]

ok so have completed the swap.



Things i had to use off my ES3 were...Alternator and alt. Mount. Power steering/mount, thermostat housing, the tube from the water pump?(dont know what its called) distributor, Engine wiring harness,Flywheel and clutch, all the motor mounts even then one under the timing belt cover.

[SZfiftyfour]

Sweet ! Now you just need obd1 and turbo

[Dr_Snooz]

Nice work! How fast is it now?

Looks like you have some fun cars sitting around there in addition to the Accord.

It has alot more power i don't feel like I'm giving it alot of throttle like my es3

[MessyHonda]

nice to see that you got a hp increase
