Hey:) I have a datsun 1982 210. Does anyone have any ideas of what engine I could put in it? I want to make it a 4 or 5 speed. Some options given were that I could bore it out from a 1.2 liter to a 1.4 liter... it has great miles per the gallon already, and am not sure what engine would give that and be able to be more powerful.
???

what engine would give great milage and more power...pretty much any newer EFI 4 cylinder of a similar size

asuming you dont want to do a full on conversion, then upgrade to an a14/15 for a modest power upgrade and keeping good fuel economy.

For a slightly more complicated upgrade, fit an l series (1.6,1.8, 2.0). Plenty of power, still resonable fuel economy.

Quote:The US model 210 [B310] was available with the A14 & A15 engines as standard & were available optionally with the A12A [1237cc] I do not believe that the A12 [1171cc or 'nominal' 1.2 litre] was sold into the US market after 1973 so you have me a little confused.

Are you sure thay you have a 210 or is it an imported 'Sunny' model [same B310 chassis code] that came with an A12

Regardless, both the A15 engine & three versions of a factory 5 speed were sold in the US & I would recomend that you install the A15 engine & the 60A series of five speed, both of which should not be too difficult to obtain & will be, as far as I know, a direct bolt-in operation.

Don't bother to bore it out. It will cost twice as much as an A14 or A15 in the first place. An A14 or A15 from Datsun 210 would be great. They have a ton more power, and actually get better fuel economy than the A12A engine you have (when fitted with 5-speed transmission). If you stay with the automatic, I reckon the A14 will get worse fuel economy than the engine you have. This is a true bolt-in project.

If you want to do some fabrication and parts sourcing, a Datsun 2-liter L20B swaps in. It will even fit with all factory parts from a 1978-1979 Datsun 510. No custom driveshaft needed.

this is a good idea.. a gx coupe with that slapd in the back

and then maybe this .. like attached to a traylor you might get it to spool up to 1rpm if pipes are sealed right

Thank you for all your advice! I will look into all these ideas. To answer one question I do believed it was shipped under 'sunny' model, it is a 1.2 liter, 3 speed, automatic... I will look about for some parts and see if I can't upgrade it to the 5 speed sounds like a good idea. Thank you.

No north american B310s were marketed or badged as a Sunny. There are badged and marketed as "210".

The 1.2 liter engine in them is an A12A (1237 cc).

4-speed or 5-speed alone will give it a little more oomph than the automatic. 5-speed won't give it any more than 4-speed, but will give it better fuel economy.

So I have an A12A automatic, and getting a newer engine A15 and 5 speed I would need a new transmission, peddles, master cylinder (slave cylinder?) and I was wondering would I have to re-do any wiring?
I'm saving up so I can get all the pieces before I start this project, does anyone have any other ideas of what I might need. Just to clarify there is no sense in boring an A12A 1.2 to a 1.4? A new engine would be better? Since the A12A is a 1.2 liter if you bore it out to a 1.4 and do upgrades does it thus turn into a A14? And does an A12A with manual transmission get better fuel economy than a A15 manual transmission? Not like it really matters more power would be less fuel efficient??
I'm not sure how long it takes to put in another engine, but I'm hoping once I have ALLL the equipment it won't take too long.

and do I need a shortened/lengthened drive line if I put in a 5 speed?
