JacobBieg Posted January 3, 2022 Report Share Posted January 3, 2022 Im considering engine swapping my 79 210 hatchback that currently has an A14 in it, any ideas? Or maybe a horsepower buff to the current A14, preferably something that is decently easy. Quote Link to comment
datzenmike Posted January 3, 2022 Report Share Posted January 3, 2022 An engine swap will also require a transmission, so additionally the transmission mount will need modifying and the drive shaft length altered. So an engine swap is more involved than just putting another engine in. I had an A14, they are about 68 hp aren't they. What shape is it in? It can be made to make 100 hp. I think cheaper than a transplant. Quote Link to comment
Stoffregen Motorsports Posted January 3, 2022 Report Share Posted January 3, 2022 There's a philosophical debate here as well - Ignorance is bliss. What do I mean by that? When I was a kid, and we engine swapped with angle iron and plumbers tape, our enjoyment was not diminished in the least by doing a hack job. Now, the engine swaps that leave my shop cost over $50k and are massive logistical headaches. For a first timer, the one thing I can say is - if going with a more modern swap (EFI) get a donor vehicle and try to retain as much of the donor's mechanicals as possible. It pays off in the long run. In more ways than one. But for a 210 hatchback, a small motor is about the only thing that will fit. I think even an L series in there is a tight fit. Building the A motor will yield a great engine, and yes, it's easy enough to get 100hp out of one, but you need to find one of the few shops left that still know anything about the A motor. I wouldn't drop it off at my local machine shop/engine rebuilder and have them do it. Quote Link to comment
datzenmike Posted January 3, 2022 Report Share Posted January 3, 2022 I believe if you can find an A10, that's a '79-'81.5 HL510 , these cars has L20B/Z20S engines. The cross member fits the 210 and has the engine mounts in place. You will need L series engine brackets for an L series engine though. L series engines start at near 100 hp and go up from there with add ones and include a wealth of transmission options including the 5 speed used in the 280z/zx and the 810/Maxima six cylinder cars. You can even get a 720 truck 2.2 and 2.4 liter engine and keep the L head and swap the blocks for a 'stroker' or LZ Frankenstein engine. But first look into what you can do with the A series engines. 1 Quote Link to comment
Tom1200 Posted January 6, 2022 Report Share Posted January 6, 2022 So I'm the resident A-series guy here; I've been racing a 1200 for 30 years. You can get 90-100hp at the wheels with an A-series and still have a streetable car. The only difference between the A15 & A14 is the crankshaft and pistons. You can bore the A15 out to 79mm. 1mm oversize Mazda Miata 1.6 pistons have a 32mm pin height can be milled down 30mm pin height for an A15. This will give you a 1600cc motor. You could also simple order custom pistons, those are around $600 for the set. The big power gain will be in the head. Find either a GX head or an H89 cylinder head. You can port the head yourself; you are just cleaning up the ports. I did mine using a dremel and looking at the pictures and Datsun 1200.com. Larger valves are available; either use modified L16 valves or by them from B-projects in Japan. Get a reground cam from Delta Cams. Isky cams still sells dual valve springs (you need those) Add side draught carbs and a header plus 2" exhaust. All of the above will get you to 100-110 at the wheels and set you back 2-3K. A cheaper alternative would be to find an A15 crank, 77mm pistons from Rockauto, A H89 cylinder head, Isky valve springs, Delta cam, header and Weber 32/36 carb. This will get you to around 85-90hp at the wheels. That can probably be done for $1000 to $1500. OR Convert to a L20 or Z24 motor. Clearly. Up the ports on those and run a mild cam. Datsun1200.com will have most of the information you need. You may need a custom driveshaft for the conversion. I like the A-series motor becuase it's light. The A15 in my race car is 185lbs complete with clutch. The 60 series 5 speed weighs 54 pounds. 1 Quote Link to comment
