DKZ engine swap

[pug-life]

Hey froggers.

My friend is looking at doing a DKZ engine swap from a automatic 405 SRi into is S1 205 rally car.

They are the same engine as the s3 205 GTi (internals and all) yes???

Just briefly, what are the things that might need to be considered doing a swap from jetronic to motronic ECU, apart from the crank angle sensor?

Is it a case of just inserting a crank sensor pin into the 205 wiring harness?

Engine has only done 110,000 km's. So its pretty new!

Cheers
Julian

Anyone? Bueller?
Surely someone has done this before...?

Hi,

I've done this swap and yes the DKZ in the 405/BX is exactly the same as in the 205.

I can't speak to the Motronic conversation though as I maintained the L jettronic on the 205 I put the motor in.

Good luck!

Yeah I think thats probably going to be the easier option, keeping the jettronic ignition.

Was there a noticeable difference in power before and after you did the conversion?

Yes there was a noticeable difference, but I did replace a 300,000k DFZ with a rebuilt DKZ. I did a lot of other odds and ends at the same time including rebuilt injectors and new AFM so all in all it resulted in a quicker and much smoother car.
