you'll have to change everything like Clair said. right down to the fuel delivery as I'm guessing the driver's pump isn't up to the job. Brakes you should get a set off a VR6 on the front and possibly look at a rear disc converion, but no essential as we all us mk2 owners know what little work the rear callipers actually do

I personally wouldn't bother with coilovers. you might need to uprate the shocks somewhere on the front to handle the extra weight. I put 16v springs on mine all round and still the front has dropped about 1/3 of a inch and now rubs on hard corners.
if you're doing it yourself QPE (07980 983095 / info@qpeng.co.uk) do a complete kit to get your engine running with 200bhp for ?900 + VAT. At the moment they only offer this kit to plumb into a mk2 digifant but I'm sure if you inquire they can tell you more than me. That'll get you past the imob, etc that all these engines have and you won't need mk4 clocks, etc.
if you want to know how much from a company get on the dog and bone and call some. Quotes from earlier in the year (so have probably changed) DesignaDubs - ?5000 / Dubsport - ?6300 / Bedrock - ?6500 / TSR - ?6500 / JBS - ?8000 / Midland VW - ?3500. Obviously you get what you pay for with everyone. I'm sure you've seen the recent work from the JBS boys on their conversions. Some companies use stand along management that gets round the imob on the OE ECU's. There's mixed views on all the management so don't believe what company A say against what company B say.
Gearbox wise I'm running a mk3 16v 'box with an uprated clutch to handle the output. It's a 180 TT lump running a KO3s turbo and should be running about 210bhp once I get a 2.5" zorst on there as my standard effort is limiting it somewhat. (ie, it bangs and pops when you let off

) Obviously custom pipes have to be made up to link it all together. Cost wise was ?4218 I think, but I had to replace a few other things during the conversion just to be on the safe side. A wishbone was heavily rusted and some of the bushes were tired. I need new shocks first to stay on the road lol.
Make some phone calls. People will gladly advise and help you out. This is dubworld after all
