v6 4 motion specialist

[adriandealone]

Hi guys, I have a v6 4motion mk4 golf.

I want to do a gearbox and engine build and also a turbo build.

Does any one know of specialist in the London area who can do a great build for me?

[Maracus]

Not London, but I can recommend APS in Brackley, about an hour away.

[Dr G]

Try all/any of the Phirm, Stealth Racing or Voodoo Motorsport.

The Phirm had a turbo'd R32 in last time I was up there.

Buy a faster car to start with? Much cheaper and better.

Sorry no help but definitely true.

Maybe sensible but not always fun or necessarily better.

The 4motion system can certainly take some decent power, there are 24v VR6 motors pushing over 1000hp = a lot of fun.

A turbo or supercharger (rotrex kits are available from the aforementioned suppliers) set up running just 6psi without having to extensively modify the engine internals will allow you to run 300hp.

Have a look on ClubGTI, VR6 owners club you will find more useful info

http://vagtools.com/mk4vr6stg3.htm also gives a few pointers.

Depends what your budget is yes but there are better bases to start from if you have a big budget and if you have a more modest budget it would make more sense to buy a faster car.

If it really has to be a Golf an R32 would make more sense and might actually be worth supercharging, they are quite cheap now.

[aka_kerrly]

^ Absolutely , the op didn't specify budget or if it's a long term project or just a brief flirtation.

Yes you can buy other cars and you'd be the first to say a RB5 or similar but having seen a fair few rotrex'd cars and been in one it was outstanding & complimented the vr6 character well.

OP what else has been done to the car? suspension and ARB upgrades done yet?

[rb5er]

Theres no way I`d say an RB5, thats a car that should stay away from too much modification if any at all.

But so many other cars would be a better start base. Totally depends on budget. Supercharger conversion + suspension and brakes etc could be anything from maybe £3k to £10k+ depending on how and what is done.

[aka_kerrly]

^ it wasn't a dig, I meant you could use a standard RB5 as an example of a preferable starting point compared to the potential cost/hassle of building a sorted 4mo but it could well be the OP wants to build a turbo'd 4x4 VW which as far as I'm concerned is still a better starting point than many other vehicles.

[adriandealone]

I already got a garrett gt35/40r and I have been told the gear box on the r32 are not as good, also the block is not as strong as the v6 4 motion.

I have ask at aps spoke with Ed they could not help me with what i want to do. the part for the v6 are not as easy to get like the 1.8t and the r32.

Also I dont want a supercharger I do love the turbo.

Thanks for the help

I knew there was one I was missing; I think they've done a couple of R36 Golfs too.

Yes R36 mk2/3 Golfs, R32 rotrex'd rallye, R32 turbo mk2 golf, mk4 Golf twin turbo* (i think) and all sorts.

I do recall seeing a Bora 4motion that was running >500+hp that was for sale fairly recently but i cant track it down right now.

That always blow up on the drag strip.

@ the OP: The Gearbox is weak. Past 400lbft, you're on borrowed time. (VW quoted torque handling is ~ 280lbft) The milled end casing that holds the gear shaft bearings ovalise under the strain, causing the gear shafts splay apart and strip 4th gear.

The strongest manual box is the O2Q, from the MK5.

For a 24V turbo, the best base car is a MK5 R32 DSG with uprated clutch packs. The R32 block is not weak. It's just less tolerant of cr@p tuners who don't know what they are doing.

What I'm trying to say is, there is a lot of exaggerated BS in VW tuning circles and no EVER tells you the full extent of the work and costs involved.

To build reliable, you need HGP turbo kits form Germany. Avoid the cheap rubbish you see on ebay.

You have been warned

That's not strictly true, I watched a 1000hp mk2 VRT flying up the strip dozens of times a day over a long weekend at Santa Pod, it was only ripping the back axle out of the boot floor that stopped him (briefly on Saturday evening but he was back on Sunday morning)

Agree in principle though that at 500hp there needs to be investment into the engine internals, a lot of investment into correct mapping/fueling and to a degree a bit of luck.

[SuperchargedVR6]

You said 24V VR6. VRT is 12V, which is a far stronger and more basic engine when it comes to boost.

What car is it? I'm not aware of a 1000hp MK2 in this country. I know of 1 in Europe and that is always blowing up.

[aka_kerrly]

True enough to get 1000hp you'd have nothing that resembles a 2.8 24v but not to say it's impossible, there are 3.6VR turbos that run near as dam it 1000hp. One is in a mk2 Golf, another in a Passat in the USA plus a German mk1 that's 900+.

I thought it goes without saying that if you are extracting 4+ times the power the original engine came with then there WILL be breakages along the way until you get it right. When you effectively get to drag racing spec engines in road cars it's even more likely that by using it on regular basis components will be severely stressed.

The 1000hp mk2 was Daniel's from Donkey Tec (I expect this is the car you are thinking about) that was over in the UK. It had emergency surgery at Stealth on the saturday night but still laid down 8second passes. I appreciate it has been a long journey to get to this stage!!!!!!!!
