Range of engines suitable for 91 civic

Hi to all
Any of the Gurus know what year of engines I could substitue for
the one that is dying in my 91 civic si? Without doing major
wiring, ecu swap, sensor replacement etc.
Thanx for any help
Cheers

if you don't want to do ecu, sensors, wiring, etc., you're stuck with
another of the same. what problems are you having?

 

Hi thanks for the response.
My son's car has been smoking for a few months, and just recently
started to lose power. It was consuming about a litre of oil a week
He drives about 200 km daily to work and back, and I'm reasonably sure
he doesn't abuse it as he is aware that a replacement vehicle at this
time is out of his scheme. (newly licenced electrician,,,just finished a
lot of exams with no income)
Anyway.. the engine was rebuilt winter 2004, new rings, replaced burned
valve, gaskets etc, and seemed to be fine for several months.
It has about 270,000 km on it, and is still in fine body and mechanical
condition...so worth a swap in my estimation.
Will be checking under the valve cover for anything obvious, (leak-down
test etc, but I believe a swap will be imminent.
Any suggestions will be most gratefully appreciated.
Thanx again
Ray

 

http://www.superhonda.com/tech/honda_engine_codes.html might
provide a bit of guidance. Further research will certainly
be necessary, of course.

 

be careful with rebuilt engines. often, it's very inexpertly done, and
you're seeing the classic symptoms. the cheapest AND MOST RELIABLE way
to go is to get an imported used motor from japan. plug and play.

and abuse is hard to do on a civic. the engine is rev limited, so it
can't be broken easily. use a good quality engine oil, make sure the
cooling system and ignition system are in good condition, take care of
maintenance and the oxygen sensor, and your 60k japanese motor will last
another 300k.

 

Without an ECU swap, you'd pretty much be limited to the same engine as
you have. Most later engines have VTEC, which requires ECU and wiring
changes. You might be able to use an early Integra non-VTEC twin cam.

Many thanks for the immediate responses
I think the used import engine sounds like the best way to go, per Jim Beam.
The re-build hassle just wasn't worth it, now to try and find one in the
Toronto area.
Apreciate the guidance gents
Thanx

Since the engine was rebuilt rather recently and assuming that it was
done so in a correct manner, I would look for some other cause for this
malady such as a plugged catalytic converter and/or engine ventilation issue.

A compression check of the engine would also confirm/eliminate the cause.

If you opt for the imported used Japanese engine, you could probably
utilize a shop "over the border" to reduce the typical Canadian import
hassle. Just be sure that the basic engine is the problem first..
