corrado 2l 16v into mk2 'rocco

[blackwedge]

Hey fellow roccophiles, last week I was offered a 95 corrado 2 litre 16v for 300 squids, which I quickly snapped up. The owner had it sat in a field for a year or so and wanted rid of it. I originally bought it to put the leather seats into my rocco, which I have done, but on closer inspection, it turns out the engine is a gem with just 70k miles on the clock. It got me thinking...... how easy/hard would it be to pout the corrado engine into my rocco? I'm sure it's been done, has anyone got any experience with this swap? I have a willing mechanic to undertake the job, but I want to know of any potential pitfalls. Am I right to think the block/gearbox and drive shafts are a fairly straight swap? Will the wiring be an issue? Any feedback at all would be very appreciated. I sit at work fantasising about seeing that 16v under the bonnet...mmmmmmmm.

Happy Easter to all.

just swap everything from the corrado into the rocco.
use the rocco gearbox to keep things simple but integrate all the modcons of the corrado loom into your old existing electrics.
word of warning
do not throw anything of the corrado away untill your happy with the scirocco. i have lost count how many times people scrap the donor car and then realised they forgot to remove a part.
you will need a custom exhaust depending on engine code as some blocks are higher/taller than others.
should be easy to be honest if a competent mechanic is doing it.

Just put un the engine and forget about all the wiring from the Corrado.

I have the engine, block, from a Passat (same as Corrado 9A engine) and even kept the KR head on.
All the wiring is a one to one fit.

I've done it on mine and used the 9a management mostly because I had it and knew it all worked properly in the car it came out of.
Physically it will fit in the bay easily, its the same height as the KR 16v, already has the mounting holes for the cambelt end engine mount and the Scirocco gearbox bolts up fine.

thanks to all for replying,

once the block is in, I should imagine that all the sensors coming from the 16v engine will just remain connected to its ECU and that ECU just needs connecting to the rocco battery. Is it really as simple as that? Joost says in his post it's a one to one fit.

Sorry if i'm asking what seem dumb questions, but I just want get a clear picture of what this swap entails before going ahead. As I'm sure you have all experienced before a 'simple' job turning into a huge mission that makes you question your own sanity and empty your wallet.

Thanks again for all the feedback so far.

Never apologise for asking valid questions fella, that's what the club is here for. Better to ask 100 questions and get it right first time.

Not a problem, ask away.

Its certainly not a straight swap as far as engine management goes if you want to use the Corrado stuff. I suspect Joust started out with a 1.8 16v car which is why he could do a swap so easily, we didn't get them officially on the Uk. What car are you starting out with, Injection or carb? If its carbed you will need to think about how to convert it to injection as the Corrado pumps and lines are not a direct fit.

With the wiring you won't be able to just unplug it from the Corrado and plug into the Sirocco fusebox, partly because they are in different places so some wires will need lengthening and others shortening, but also because the Corrado has a later CE2 fusebox and the Scirocco the earlier CE1 meaning wiring will need to be stripped and spliced which all takes time.

I certainly don't want to put you off doing it, once its in and running it really is a fun car to drive, but it won't be straightforward and will cost you more in time and money than you think. I think mine was 2 days to get the old engine out and new in, then 6 months I think, working weekends to get the wiring sorted, exhaust and 4 branch manifold with Lambda boss, fuel pumps and lines converting from carb to injection sourced and fitted.

Hey Tim, my current engine is the 1.8 8v DX code engine, if i could get hold of a wiring diagram pertaining to this particular engine swap I figure it will be worth it, my rocco is my only car so i don't want it off the road for months. its the endless trial and error that i'm trying to avoid.Anyway I shall continue to research it as see how it pans out. By the way, where is the engine management system for an 1988 GTX located anyway?

No MK2(or MK1) Sciroccos had an engine management system, these are real belt and braces old school technology cars.
The most hi-tech thing on them is electronic ignition!

Haynes Passat manual for 1988 to 1991 models with a purple front has 9a wiring diagrams as well as details about the engine. It's what I used to work out which wires I needed to keep and which could be removed, Rubjonny's fusebox FAQ in the electrics section over on ClubGTI was also much needed to identify the wires going into the connectors at the fusebox end.
Something else to keep in mind is that the later Corrados had an built in immobiliser with a chip in the key, a separate control box, transponder ring and coded ECU. If you don't want to keep all that, you'll need to find an early model ECU or someone who can disable that for you.

Something that may help if you decide to go for it, when I set mine up I ran the engine loom into the corrado fusebox, and gave it power and earth from the back of the existing one to test everything as I removed wiring I didn't need. If it stopped working, it was easy to troubleshoot and put back until I was sure I'd got everything I needed and removed what I didn't. Once I got to that point I could start splicing it all into the original Scirocco loom.

I'll see if I can find any of my notes on what I kept and took out if you like?
