FWD to RWD

Post by makzin » Thu Jun 13, 2019 8:46 am

Sup People.

Was wondering how much or how hectic will it be to convert a front ween drive car to a rear wheel drive. I saw a WV Mk2 that was rear will drive. So it is possible but just want to find out what to look out for on such a project

I would seriously suggest that you perhaps hop onto the internet and google this or check out Youtube, I'm sure that many others worldwide have tried and documented this.

Anything is possible in theory, but unless you are a very skilled panelbeater with lots of time, CAD/CAM skills and with access to some jigs, cutting and welding tools, it's not something for the feint hearted.

I did some research. I have no panel beating experience but have a project I've been meaning g to start. Just need to get direction. This RWD was an idea but after a few hours of Google it will very expensive

It will essentially be a full strip down to a bare bodyshell and cutting it to pieces to fit a modified floorpan to accommodate the now longitudinal engine, modified firewall, transmission tunnel, propshaft and diff to start with. Then adding the various mounting points for the suspension and drivetrain and strengthening of the chassis, where necessary. You will essentially be building a car from scratch.

I have seen how Volkswagen Motorsport builds an S2000 Volkswagen Polo 4-wheel drive rallycar, the tools required as well as the CAD designs involved. If you have no relevant experience and presumably not the tools referred to earlier, you are in the deep end of a bottomless pool of wallet emptying effort, as confirmed by Google.

Just for argument's sake, what about starting with a syncro drivetrain? A Mk2 Syncro (for example) doesn't have a longitudinal engine. Is the body all that different from a FWD Mk2?

Everything up to the firewall will probably be OK, perhaps just having to accommodate the Syncro gearbox and transfer case, but from there on backwards is a redesign of the floorpan to accommodate the propshaft, exhaust, rear suspension and so on.

Also bear in mind that trying to find a Syncro set up to fit a MK2 body will be impossible in SA, as we never got them here, so you will need to import a used set-up or try to find one of the two ex-factory Golf Syncro's that were rallied here in the late 80's, early 90's. You can probably try to find a set-up as used in the Volkswagen T3 Microbus Syncro, but the dimensions will be totally different and would require heavy modification to fit.

Although it sounds like a lekker project, there are so many things to consider, of which the price of the components is probably the cheapest. It's the cost of planning, tools, labour and trail and error that will determine the project's success.

Assuming you get the whole project done, the next big hurdle would be to register the whole lot if you intend using it on our roads. Different weight specifications and most probably a different engine. Getting insurance should be fun too.

To quote my Dad - If the short cut was really that short, the long route would have gone that way.

So a engine swop is the safer bet.

A client of mine wanted to build a Mk2 Rallye clone.
He found the complete running gear (front suspension, gearbox, propshaft, rear diff, rear suspension, etc) somewhere on Ebay, but the cost to get the stuff to SA would have been over 6oK. And that excludes the price of the parts, that was just the shipping costs.
He did calculations and what not and IIRC, the rough figure was around 200K for JUST the parts needed before the build process would even begin...

Needless to say he canned the idea and did an ABF turbo setup.

I'm not needing that one up. Recently bought a Mk2 GTI with a dead engine and gearbox.

It needs: engine, gearbox, seats and dash.

2.0 litre 8valve or ABF 16valve plus gearbox and some other toys to make it work would be a ideal combination. Plus no modifications to body or chassis required.

Trying to do a unique build with a Mk2 is going to be tough and very expensive if you're not able to DIY,
every possible combination of mods/drive-train/engine was done before ,anything is possible with loads of cash.

2008 VW POLO GTI - 76mm DP + 63mm exhaust , induction, FMIC, Thanas Tuned
