      Man, your advice as been priceless. Gonna strip my head and put a spacer gasket in there to lower the compression like you suggested. And take off my plastic intake to get painted up and stick it back on. Pictures will follow on Monday. Thanks again.

      I say you put that monster on some good rain tires, and with the amount of power you will be making, just drive across the Atlantic

      How did you sort out the driveshafts? Did you use the original driveshafts that came with the synchro assembly or did you have to make custom driveshafts?

      Thanks for the message.
      The original synchro/rallye drive shaft was used on the wheel/hub side of the axle and the bmw one on the differential side. Then the two shafts were fused together then balanced to remove any risk of vibrations. The same was done on the front ones to go from the R32 gearbox to Mk1 golf hub/wheel.

      Is the bmw rear the same ratio as the haldex rear, cause i thought the haldex rear was 1:1 or some thing. also what is going to act as the center diff. Maybe im missing some thing but i dont think shes going to handle well with no center diff?

      I was wondering this also. The front and rear final drives are the same in Haldex cars to keep one end from over driving the other. 50/50 distribution front to rear has shown some ugliness in regular around time driving as well.

      But Im curious to watch this keep goin. Looks like a LOT of fun :p

      Check out this link

      http://www.supercarsite.net/volkswagen/golf-r32/2005

      The haldex is listed as having a final drive ratio of 4.24:1 and the closest i can get to that on a standard bmw diff is 4.27:1. Even then i have to consider tyre sizes to make the miles per hour and revs per minute match up. I've manage to get the perfect blend of tyres and ratios so this car should drive really nice, I hope.

      so you're using the 4motion gearbox, disconect the front axles put the bmw rear diff on and its rwd??

      if so.. could that also work with a syncro gearbox?

      GREAT Build btw

      Hi,
      Not quite. I'm still using the R32 engine and gearbox but NOT the haldex diff from the R32 set up. I am using the bmw one instead so i can run AWD. My initial idea was to run a VR6 engine with bmw gearbox and bmw diff. That would of been RWD but this option was easier.

      Did you want to turn a syncro into RWD?

      Wouldnt this make the car full time 4WD? The Haldex and the Syncro rear diff control power transfer to the rear wheels where a BMW rear diff is driven 100% all the time. Is this the effect you are going for?

      Hi,
      Yeah, that exactly what i was trying to achieve, permanent 4 wheel drive then I don't have to worry about any wiring as far as the rear diff is concerned.

      LOL! Thanks man. Doubt I'd take on another build like this one. Having the shell with the wider arches made things a lot easy in terms of not having to shorten anything on the back axle. So more of a one-off build really.

      Thanks for the updates you have been giving us.
      You got a strange way of updating (updating in your first page of the thread). I was about to ask you for more diff mounting pictures and upon looking back on the first page I saw that you have updated already. Nonetheless if you have more pictures I am sure we all wont mind

      Car still in paint shop, but due to get the interior and engine bay painted this week for sure. Here is a preview of the colour the car will be finished in.


      VW Sam's VR6 Turbo Mk3 Golf fresh out the stray booth!

      This weekend was a wash out. All I managed to do was get my tank. I'll be using the petrol tank from an E30 bmw as it already has a tunnel running down the middle of it plus it's metal. A few cuts here and there and it should fit back in the space where the original MK1 Golf tank was.


      E30 BMW Petrol Tank

      Sized up the width of the tank and the car and there isn't much difference. Still needs cutting tho. I'll do that this week.

      ok so you're going to run 4WD

      yes i was/am thinking off making it rwd, just tryin to find out if it's posible and how..

      Ok, so rear wheel drive.

      Main problems to overcome are running gear, steering and engine mounting positions. I'm in the UK so most of the cars I will reference are cars from over here. Hope this doesn't confuse you. I'll try to add pictures.


      Running Gear.

      You could choose the running gear (axle, diff, prop shaft and gearbox) from a car that already runs RWD. I was going to use stuff from a BMW E30. They are cheap and easy to come by (well over here anyways). first step will be to choose the VW engine you want to run (i'm assuming you'd want to use a vw engine).


      BMW E30

      Next step would be to mate a VW engine to a BMW gearbox. The bell housings unbolt so i was gonna get a VW to BMW bell housing made to make the two parts could marry up. This is specials work as the spindle, clutch and and engine will all need to work as one. It is possible as i had a guy who was gonna do this for me. VW camper gearboxes are mated to Subaru engines in a similar fashion.


      example of a VW bus transaxle to Subaru engine bell housing.

      Once you get you engine and gearbox mated then you start looking into getting the engine mounted.
      The car will need tunneling out to get the gearbox to sit in the right position. Getting an E30 donor car would be useful as u could use the tunnel and a other few bits from it. At any rate, stay away from the 4 cylinder ones. 6 cylinder ones are better.

      At this point most people would just want to cut the BMW floor pan and put their VW shell on top of that. I think that's easy but pointless as it no longer is a VW but more like the child that would result from a BMW/VW drunken one night stand. Neither side really ever wants to claim ownership of the bastard.

      Once you have your engine all mounted then it will be time to concentrate on getting the back axle in place. I used a VW rallye. It has independent rear suspension and disc brakes as standard. A VW Syncro axle could also work.


      VW rallye

      Once you've located your back axle you'll need to get your diff mounted in the frame of the axle in place of the standard VW one. See my pic's for an example of what this looks like.

      Steering
      I was gonna use the front suspension setup from a ford escort as this has the steering rack to the front of the car and not bolted to the bulk head like that of a the MK1 golf. This again is specialist work but it is possible.


      Front mounted steering rack.

      This is what i was gonna do but found 4x4 a quicker and cheaper option. But nothing is impossible and if its RWD you want then the above is a very rough guide that should give you some idea of how to proceed.

      Here is an example of a mad ideas that have been made a reality.


      Hayabusa Turbo-Powered RWD Mk1 Golf

      http://www.youtube.com/watch?v=fUH8S...eature=related

      U could also run a mid engine setup if you wanted to take the easy way out.

      Had some time after work so i thought I'd get to chopping my E30 fuel tank to sit nicely in the space the golf one used to sit. Had to wash it out with soap and a pressure washer so it didn't blow up once the chopping began. I could probably have just gone out and bought a fuel cell to sit inside the car but they are placed under the car from factory for a good reason, plus i need one with a tunnel running through it anyways.


      Used an E30 tank as it already has a tunnel for the prop shaft

      Once its welded back up, i'll pressure test it and strap it back to the car.

      thank you for the write-up

      my first idea was to use a quattro gearbox on a vr6 because ''034Motorsport'' have the custom parts for this for sale

      but since i bought a syncro i was thinkin of the next thing;

      i looked at this drawing and thought if you disconnect the front axles, that it will go 100% to the rear end.
      and just replace the diff with the visco for a bmw one

      would this work? if not, i think i'll keep it just syncro

      once again, thank you very much for your help

      Hi mate. Do you have more details on the electric power steeering setup for the Aussie readers?...we have the same problem as you in UK...no power steering on Mk l's

      ...and that stupid crossbar for the RHD brakes ...get rid of that if you can too!

      Hi,

      So is it an MK2 golf sycro you have?

      To the best of my knowledge, if you disconnect the front drive shafts you'll still have a 50/50 as the gearbox is design to run 4wheel drive. I was reading up on the 034motorsport site and the it seems the Quaife ATB Front Differential is similar to a limited spit set up but still delivers a near 50/50 split. If you already have a syncro you could change the vw rear diff and Viscous coupling as it will not be able to handle all the power you'll be putting through it, then get a bellhousing made to run your engine with a RWD gear box, then get the engine mounted longitudinally, connect with a prop (shortened and balanced in need be) then you're good to go.

      If you want to run it as 4WD with a VR6 then that's a lot easier. If you locate a gear box and diff from a V6 4motion Golf/Jetta/Audi TT/Audi A3 then the hardest bit would be to get the rear diff mounted in place of your syncro one. I haven't explored this fully but i doubt the V6 4motion diff will fit in the space of the syncro one as the V6 one is a bit bigger. A skilled engineer can easily make up brackets for that. The 4motion box will bolt straight to a VR6 engine. (gearbox mount might need some fabrication). Prop shaft might need shortening and balancing. Then that's your running gear in place. The only thing i'm not sure about is the wiring side of things for the V6motion haldex diff. Once you get around that, it should be a sweet conversion. If is a genuine mk2 sycnro you have, then u won't have to do any tunnel work, just get you gear selector mounted in the right place.
