I had looked into doing this conversion. It's not hard. You will have to change the engine mounts obviously. The L series is a bit taller than the A series so u will have to try and get it as
low as possible. The gearbox mounts will also have to fabricated. Also, the L series gearboxes have a hydraulic clutch, so u will either have to convert it to cable or get a clutch reservoir
connected to your pedal. The drive shaft will have to be cut and replaced uni's. I think that's all? The reason I didn't end up doing is because of the weight of the L series. I didn't want
understeer. Hope this helps.

Hi Simon - here's some info about a L18 that someone put in their 1200. I reckon there are better choices out there now but maybe this will help you make up your mind. This is from Martin
Pots Website at
http://members.iinet.net.au/~mpot/DatsunMods/ ... has heard of someone who installed an L18 engine into a 1200. Then entire job was done by an
apprentice mechanic. It was a huge job, and involved deeply scalloping the cross member, engine mount mods, and reshaping the sump.
The engine runs custom extractors for clearance, with a 2.5" system and 3" tip. Induction is twin 45 side draught Webers, which give an incredible throaty roar under acceleration. The head
was extensively worked, with maximum porting, valve increases and a huge cam.
A factory EFI setup imported from Japan was tried, and found to be much smoother, but too restrictive above 6000rpm when used with the cam. The gearbox used is a reverse H Japanese race box.
The radiator is a custom 5 core with a big thermo fan. The diff is a shortened 1200 Ute diff.
The engine produced in excess of 170 hp, and was incredibly quick!

Well for less work and money fit an A14-A15 no other mods needed and can get same sort of power with less weight :)

Not wanting to sound rude but for all the effort the choice of an L series would be a waste of time and money, as has been said already you can get as much power out of an A series anyway,
You could build a sleeper 1700cc stroker and there are no structural changes required and it still looks like a 1200 to nosy buggers. If your intent on going bigger look at the later
technology from Nissan like a CA 1600/1800 or the alloy SR series. Or if you're really keen an alloy quad cam Nissan V8! I've seen one in a 310 Sunny and there's plenty of room. But any
engine swap will require the gearbox tunnel to be modified (wider and probably higher) unless you can find a car that was an automatic as these usually have a bigger tunnel.
Hope this helps, but if you are almost finished on the conversion dont let this letter bother you. I havent started but I am going for a bored and fully worked 1500.
