KELMO Posted December 24, 2018 Report Share Posted December 24, 2018 I probably won't be too much help here but..... The "J" motor and the "A" motor are almost identical in design. In your part of the world "A" motors seem to be more available. Or more to the point, there seems to be more Sunny's over there than over here. My guess is that your 3 spd is a column type affair and most 4 spds will be a floor type shift. 1 Quote Link to comment
Kodu411 Posted December 24, 2018 Author Report Share Posted December 24, 2018 thanks guys.. I will look for a A tye engine.. at this stage I need something simple and less effort. 1 Quote Link to comment
reza Posted December 24, 2018 Report Share Posted December 24, 2018 I would highly suggest not swapping. Pull the engine, give it new rings, cam, dual carbs, header. https://ratsun.net/topic/6785-e1j13-interchangeability-with-mgnash-parts/ This thread should be a sticky in the 411 section. 2 Quote Link to comment
datzenmike Posted December 24, 2018 Report Share Posted December 24, 2018 On a J13 3 speed? Rebuild, yes but this engine only has 3 main bearings unlike the L series which have 5 and can bear the weight of the golden gate bridge. The later A series had 5 speeds too. 1 Quote Link to comment
Kodu411 Posted December 25, 2018 Author Report Share Posted December 25, 2018 Thanks for info huys. I found A12 engine .. just wonder how hard to put them in to 411.. also my J13 has 3sp column.. can i fit 4speed in to J13 engine..? 1 Quote Link to comment
datzenmike Posted December 25, 2018 Report Share Posted December 25, 2018 If getting an A series, get an A series transmission. There were 4 and 5 speeds. The 5 speeds are quite rare as they also fit MGs. The '66-'68 520 and '69 (first year) L521 were J13 with 4 speeds. 1 Quote Link to comment
Kodu411 Posted December 25, 2018 Author Report Share Posted December 25, 2018 yes I can find A series engine with 4speed gearbox.. since i havent done ths b4 wonder how hard to do the engine mounts.. or can i use A series engine mounts thanks 1 Quote Link to comment
datzenmike Posted December 25, 2018 Report Share Posted December 25, 2018 You have me there, I have no idea. Hopefully the transmissions are same length or the driveshaft will need modifying too. 1 Quote Link to comment
Swedishcadillac Posted January 9, 2019 Report Share Posted January 9, 2019 A lot of welding to subframe is required for the a-series oil pan to fit. I welded custom motor mounts.Header and steering box are tight. Check my build in project datto “a 410 goon moves to Hawaii” 2 Quote Link to comment
jfbrink Posted January 27, 2019 Report Share Posted January 27, 2019 To reinforce what @Swedishcadillac said, one of my 411s came to me with an A14 sitting lopsided in the engine bay. I spent some time exploring how to make it fit, and it required loads of cutting, which didn't seem worth it to me. Jesse. 1 Quote Link to comment
Swedishcadillac Posted February 3, 2019 Report Share Posted February 3, 2019 these kind of shenanigans.... 2 Quote Link to comment
Pedro Posted April 30, 2020 Report Share Posted April 30, 2020 MG 1.8L engines are one of the better engine swaps, just keep your J13 sump and pickup to suit. Engine mounts will need fabrication, and you will need to get a new driveshaft to match. It's a slippery slope in costs once you get started, so if you aren't chasing power, I'd consider a J15 from a 620 ute (they are cheap over here). If you are more hands on like the guys above, get the grinder out and go nuts, but those kind of mods on crossmembers require engineering in Australia, unless you are a master and can make it look factory.

A bit late on this comment but the metric R1600 roadster engine has 5 main bearings. The need to route the exhaust through the left front fender, avoiding interference with the carbs and the starter solenoid would be eased due to the right hand drive in this case. No carbs and no steering worm interference. You could use 510 starters. Just routing the exhaust would take ingenuity. An added bonus is that this metric engine can fairly easily be upgraded to 2 liter capacity. Edited May 2, 2020 by MikeRL411 Added fact. Quote Link to comment
