My H23 has around 160,000 miles on it and it is pretty beat. The previous owner took terrible care of it. I found an H23 with about 115,000 on it for $300. I was thinking about buying the engine and swapping mine. My questions is: will it be a direct plug and play operation considering I have a 5-speed and the other engine is from an auto?

should be. i hear it doesnt matter about the tranny when swapping motors

That's what I'm hoping. $300 isn't barely anything for a perfectly running motor with a lot of life left. If it's compatible without modification, I'm definitely getting it. I'm tired of hearing my valves tick and mass hesitation!

the motors are the same you just need to swap the clutch ass. from your and pull off alll the and sh** from the other one..

just to chime to chime in, if the other motor is a vtec you need the ecu and wire harness

Everything will drop straight in as long as you use the appropriate ECU (Manual ECU for manual trans obviously), and as long as both cars were the same OBD system. You'll be fine. Go for it.

All of that said, have you even considered working on the existing engine? Valve tick is most likely gonna be on the new one, as that's pretty much Honda and their loose clearances...and the hesitation could easily be just a tune up.

I say do a tune up, get this one running great, buy the other one and have it to build the sh*t out of so that it'll be mean as f*ck when the current one finally dies ;)

If not....I'll buy your current one for $300 lol

BTW 160k isnt THAT many miles...mine has 195 and after I did a seafoam and new plugs pulls as hard as my freinds with a 60k swap lol

It's H23 and $300, definitely not VTEC, lol.

I will use my ECU and they are both OBD1

I've tried to do a tune-up and I'm just not mechanically inclined enough to fix it. It runs like ****.

my h23 is from 93 and has 250k on it, still runs like a champ. 300 seem low to anyone?

There are no mistakes, only opportunities to learn.

It's because the previous owner did absolutely nothing to keep the engine in good condition.

__________________

auto and manual engines are the same. as long as they're both obd1, your good



BTW, you might as well doing the timing belt and seals while the motor is outta the car. much, muchhhh easier
