Have been offered a 4.0 at a reasonable price and would like to ask the members a few questions.

Would the C4 auto off my 250 I have bolt up to it?

Is there anyway of fitting a redline manifold to run carb/LPG through this motor rather than injection?

Would also like to know about the power steering?

What mods would be needed to fit the engine to a TF corty?

Cheers John!
 
What year four-o? Some should be free, as they are that iffy when aged. EF/EL would be good and maybe you'd pay a few hundred. You can get a C4 bellhousing for about $350 from CRS, I think. Not sure on the fanimold; maybe XE will fit.
 
the intake manifolds on the OHC motors have the same port spacing as the X-flow manifolds but a totally different bolt pattern. you could make an adaptor or cut the flange off an X-flow manifold and weld a OHC flange on to it. are you planning on running it on straight gas? as there was a straight gas version of these motors available in the AU series. that manifold should bolt on.
 
You can use the manifold of a center point injected 3.9 from an EA
But I would consider this a step backwards

You dont need a carb to run LPG just a butterfly
You can use the STD throttle body and have A little thing fitted to it so you can run gas then just block the injector holes
 
The C4 trans, carby intake will fit up with some work, but the Cortina hasn't enough room for the longer 4.0 unless you do some work on the front body work to clear the balancer and ancilary drive.

The way to fit the C4 is to run an adaptor like in the Driveline section, and fit the six cylinder C4 trans, not the V8 C7/C8/C9/C10 (V8Windsor or Cleveland version).


You just cut the back end off an ohc crank, and mill it back to 9.5 mm. Then get a 470 square 10 mm steel plate, and profile cut to the combined space occupied by the stock trans mission and the exisiting C4 trans. A few bolts, and you are there! The starter must go in x-flow position, not in the ohc position. Flywheel is X-flow, and source the metric bolts Rod uses in his CRSOHC to Supra 5-speed coversion. He makes a crank spacer, all the stuff you need is there.

If you want one, talk to CRS.

I'll build one oneday, but I've got a bucket load of current projects to do.
 
just spend your dough on a 250 and reap the benefits of easy hp and torque,ease of fitment,lack of fandangled electric doodads.parts for 250 engine are lying around everywhere.plus you ever seen a 4 litre with near a millon kms on it without having it's head off,somehow don't think so yet the old 250 has proven and still is proving reliability that is second to none.x-flow motors have been going since 76? till what 92(correct me if wrong)whereas 4.0 has only been here for ten odd years or so and they had so many problems.yeah mate do yourself a favour and stick with a x flow,they be the best.this is only my opinion so it's up to you!!
