Considering engine swap: Opinions on 1.8l?

[green71]

Well, things are looking a bit expensive for the repair of my 1971 1.7l daily driver engine. The brass gear on the crankshaft that drives the distributor is shot & must be replaced. I’m disinclined to do this job myself, as there’s no telling what I’ll find once I’ve got the case split. (My diagnostic/troubleshooting abilities are near nil.) Two mechanics have bid $1500 or more to do the job, provided no additional damage has been done to the engine and no new bearings, etc. are needed.

I’m considering an engine swap. There is a good-condition 1.8l available for a fraction of the repair cost ($350), and the mechanic will R&R the motor for around $280.

Does this sound like a viable alternative? What are your opinions of the 1.8l engine? I understand it produced the least horsepower of the stock engines. Is it noticeable as compared to the 1.7l? And can a bit more power be coaxed from it via ignition, exhaust, etc? I'm in Boise, ID; I don't think emission standards are as high here as in CA.

Any feedback/suggestions would be very appreciated!

TIA,

Mark

I have the 1.8 in my '74, yes on paper you do net out a few HP less but I would guess you will probably never miss them. If your 1.7 is tired and the 1.8 is fresher then your net HP may be the same. One good part is that the 1.8 heads do have larger valves than the 1.7's. Is the project not an option for you to remove and install the other engine? Really is not all that difficult but I do not know your tool and/or working situation. The FI should just bolt right across and if you know someone that does some smog checks you could richen the ECU dial to compensate for the increase in displacement if it is even needed.

The 1.8 has a completely different fuel injection system....so if you are familiar with the D Jet the L jet on the 1.8 is going to be a challenge.

I like the D Jet better. If yours is in good condition, consider the swap of the FI....

I have a fresh 1.8 If you need one E-mail me. Steve

You know a few years ago I rebuilt a Type 1 motor. Only thing I had done was the line bore (not normally req. type4) deck the case (highly recomended) and balance all rotating assy (very highly recommended). Bought new bearings and gasket/seals. I think I was into it for like 500. then I added 94 piston/cylinders and fly cut heads. Building a motor is not that tough with a good book. With the money you save you can put back into longevity or HP! Fuel injection is what will empty your wallet.
