as the title says -

my brothers engine is belived to be shagged in a way and we have a spare 1293 witch has been slightly modyfied racier cam ect
but it is a carb engine would it be a straight swap over puting his injection unit on that enigne with all the sensors ect and would it work untill we can get his engine fixed ?

its a 1995-6 sidewalk with a 1275 spi engine in

[Dev]

In theory yes this could work, Sprocket had taken the spi about as far as it will go, with boring to 1399, so he would be able to confirm for you.

Jackman is currently building a 1293 spi as well.

What ecu are you planning on using to run this? What compression ratio?

Do you have a non cooper or a cooper ecu for it?

[Sprocket]

All depends on what cam is in it.

If its A+ engine then it will work, its a straight swap, however, the cam may be the problem. It will run but not very well and probibly fail emissions with balloons and streamers

Find out what cam it is.

Failing that, swap the cam out and fit the standard SPi. Dont fit anything other than the cams designed for Injection engines, for various complicated reasons

hey thanks for your help but i have just been told that it will no work as i dont have a crank sensor :S on my carb enigne for the spi's ect to attach to

[Dev]

You can rectify that by fitting a crank sensor scott.

If i can i'll get a pic for you if its ok with sprocket or get him to post a pick of how you can modify it to run.

[scottyegg]

ahhh so it might work yet yeah sure any help would be nice

[AlexM]

If you wanted to fit a crank sensor wouldnt you have to fit an injection flywheel and clutch assembly?

[Dev]

No sprocket fitted a trigger wheel on the end of his crank with the sensor off that.

I'll need him to come here and confirm exactly but my understanding of it was that it worked that way or could do.

Sprox over to you.

[Sprocket]

Unfortunately i have not yet had a standard Rover ECU working on a different crank trigger, YET. I will be in the next couple of months when I get this other 1293 engine running for some one else.


Its a simple job to swap over the flywheel and its housing, dont see an issue.

No one said engine and gearbox

Athough I did assume things and we all know assumption is the mother of all f$&k ups

[scottyegg]

so my best bet get a ;

carb fuel tank
carb front loom
carb fuel pump

what else would i be looking at to change over to carb ?

[Sprocket]

Up to you but i'll move the topic back to the technical section is you swear in the injection sectuon again, LOL.

Whats the problem with swaping over the flywheel and housing?? Your going to all the troble of fitting another tank, carbs and wiring loom which incidently is not a plug and play job.

Still not found out what cam is in the donner engine?

[scottyegg]

basicly my brothers engine is nackerd no oil pressure at idle nocking noises ect and for ease of it we have a 1293 carb motor sat in the garage which the guy we bought it off said it had been bored out and had a racer cam in it but i dont want to putt it apart for the sake of it

i just wanted to know if we took my brothers "bare" engine out and put this "bare" engine in would it work

but it dosnt have the crank senseor mount

[Dev]

Put the flywheel housing off the SPI on to the 1293 including crank sensor, then.

[scottyegg]

just the fly wheels houseing not the flywheel or anything else ? and the rest would be a straightswap

my other question would be about the exhaust would a cat go by the age of the engine and engine code ? or by the age of his car ? as this engine didnt have a cat but his car is a 96 with a cat

[Sprocket]

You have to remove the flywheel to remove the flywheel housing. You then need to fit both the flywheel and flywheel housing off the SPi onto the carb engine and , woo, it becomes an injection engine. Still the cam problem, need to know what it is before you do this. by the sounds of it, no one seems to know this. It will work but how well is a different matter, may drive perfectly well but might not pass the MOT emissions.

Im going to make the decision for you.

Either get another engine of known specification or fit carbs.

Lol, never thought id say that last bit. Another one bits the dust, again for the wrong reason. Good luck persuading the MOT tester that the engine should be tested to a different emissions level than what the computer tells him. Its getting increasingly harder to do this, and my guess is that the reason is to prevent this from happening in the first place. And it wont just happen the first time you have it tested withh the replacement engine, it will happen EVERY time.
