Revision as of 10:19, 11 March 2007

The Toyota 4A engine variations are a popular swap into Datsun 1200s. These are 1600cc engines, so are a significant upgrade in terms of cubic inches alone. However, it is the DOHC 4AGE that shines with impressive power. Also notable is the 4AGEZ supercharged engine from the Toyota MR2.


NOTE to newbys: Beware of mentioning rotary-powered or Toyota 4AGE-powered 1200s. Some club members may get offended! But really, these are also excellent engines that fit in fairly well. Just don't tell anybody ;-)

Counterpoint: The 4AGE weighs the same as the better engine... Nissan's CA18DE. The CA18DE is 200cc larger, has bigger everything. So you can get away with the same mods as a 4age and get more power.

The biggest thing that has to be done was a fabricated header, because the 4A manifold is large and does not clear the LHD steering box. You may not have any trouble with a RHD car.

Swap Overview

The conversion isn't bolt-on its all fab work:

  • Engine mounts
  • Gearbox mount
  • Custom cooling system pipes
  • Custom exhaust

No one sells a "kit" to fit the 4AGE into a Datsun 1200.

FWD 4AGE's use a distributor which ends up in the 1200 glovebox and heater/demister box. This means modifying all that. That isn't easy. It's almost always a FWD engine in Australia, unless you can get a Japanese RWD AE86 Engine.


Source for Engine

RWD 4A Engines

  • AE71 was the 1983 Corolla, with carbureted 4AS SOHC engine.
  • AE85/AE86 was the last RWD series (1984-1986) with fuel injected DOHC 4AGE engine

They are 25kgs lighter than a Nissan CA18DET engine. Most people take off the supercharger and place on a turbo for much better performance and then loosely call it a "4AGTE".

Formula Atlantic 4AGE puts out 240 bhp.


Gearbox

Use the gearbox that came with the engine. Don't try to fit it to the Datsun gearbox, because the Toyota box is much stronger.

There is just enough room for the t50 in a Datsun 1200 manual tunnel. The 1200's speedometer cable screws straight on.

Don't have to cut the tunnel, put in a T50 5 speed, just cut off the two mounts in the tunnel, cleanly and the box fits perfectly.

T50 is good to handle the torque from a 4AGE, but not from a 4AGZE (supercharged engine). A turbo conversion should be OK at low boosts. Otherwise you'll need a stronger tranmission like this one:

The AE86 differential is strong, and bolts into the Datsun 1200.
