Which loom to use for zetec svt to csr260 duratec conversion in s3 chassis??

[vstryker]

Does anyone know which loom I can use?

 

Caterham 38L035A

Cosworth YD8048

 

As stated above, my current motor is a 2.0 Zetec SVT and I'm working on putting in a CSR260 in an S3 chassis. I'll also be using the Cosworth MBE ECU. I would like to use the Caterham loom as it is 1/3 the price but will it be plug and play into my chassis loom with the new engine and ecu?

 

TIA

A little off subject, but it would be very interesting to get both engine weights in similar configuration or as close to possible. This debate has gone on for almost a decade.

 

Granted, this would be a comparison of 2L vs 2.3L.

Yes, I'll definitely do that. As of now, it weighs 1220lbs with 3/4 tank when I corner weighted it.

When I built my S3 in 2007-2010, I was about to install the Cosworth 2.3 Duratec when I learned that my car had come by mistake from Caterham with the Zetec loom. I learned later that there are a number of functions that a Duratec-specific loom has, that are handled in a different way by the Zetec loom (I'm speaking in layman's terms).

 

I did not want to completely disassemble the car to install the correct Duratec loom, so I took my mostly-assembled chassis to Nathan Down at Thomas Vintage Motors in Boulder, Colorado (40 miles away from where I was building my Seven). Nathan is a graduate engineer who developed the SV for Caterham, where he worked for several years. He was able to reverse-engineer my S3 to function with the Duratec engine and the Zetec loom. I lucked out, as there was probably no one else within tw thousand miles who could have got my car running correctly with the loom that Caterham had installed.

 

Send me a PM and I'll send you Nathan's e-mail. He may be able to give you some quick answers about the engine and loom change that you are considering.

When you say Zetec Loom, do you mean the engine Loom itself or are you talking about the chassis Loom? I'm planning on getting rid on my zetec engine loom & getting the duratec engine loom for the R400 that caterham supplies but I'm still waiting on word to see if that will plug into my existing chassis Loom.

 

If you're talking about modifying the chassis loom itself to be able to mate it with the duratec engine loom which I'm hoping I do not have to do, then that will be a PITA. I was hoping that my 2005 chassis loom hooks up directly to the Caterham duratec Loom 38L035A to save me all the trouble of rewiring it.

The Cosworth engine includes an engine loom. Therefore, any *adaptation* would occur at the chassis loom interface. That interface is documented across all of the models - so I wouldn't call it "reverse engineering".

True I believe, but there may be one other difference though, in that the main bundle of chassis loom wires runs up the left (intake) side of the Duratec (at least on mine) to reach the starter, intake, and whatnot, where I would imagine it would need to run up the right (intake) side of the Zetec. The only issue that might arise from this is that your turn signal wires will be opposite on the front only, as mine were.

 

Maybe everything will still reach with the wires running up the right side? Doesn't seem like it would, but maybe?
