The hole for the hoses in the TB is a tapered hole at the end and is very smoothly finished, and I believe the brass bit is interference fit. Might be worth looking for a way to drill a hole, then tap a thread into it which you could screw some sort of hose fixing into it. Some threadlock of some sort and you should be able to create a gas tight seal.

Yeah, that's what I thought.

Got plenty of brass fittings, provided that's all it is then it should be pretty simple.

I'll keep you all posted.

Ok - Time for an update!

I have managed to pick up an 06A 133 062 C part, on the cheap for £45. 60mm internal diameter.

It comes with the fittings for other hoses, and our suspicions were correct - both just go back into the throttle body after the butterfly.

That means that 06F 133 062 also can be used - all you need to do is drill yourself a hole after the butterfly and tap in a brass hose fitting!

Now all i've to do is get some piping to hook the airbox up to the throttle body... Internal Diameter 60mm. Any suggestions on where to get some?

Well - i'll bump this back to the current status:

IT WORRRRRRRRRRRKS!!!!!!!!!

MUHAHAHAHAHAHAHA IT WORRRRRRRRRRRKS!

Although... The idle is extremely lumpy to the point of nearly stalling. I suspect this is because the throttle body needs a vag-com adjustment. The response however is sharp. Very very sharp.

Feel any faster?

Or not really driven it since?

Looking forward to further updates. You may well be able to get the throttle body to adapt by removing negative battery terminal, then positive, holding both together a while (to discharge caps etc in ecu). Connect positive, then negative. If it works you should be able to see the valve move just as you connect the negative lead.

It does feel faster. Much improved throttle response, and a fair bit nippier... Not got time today to tinker much further but it's much improved. Will keep people posted as soon as I get progress.

Eagerly awaiting updates, Dr. Frankenstein!

I love it when a plan come togther I'm glad there are people like you on this site who are willing to tinker with things and mix and match parts etc..

I'm keen to see the pics of the installation

^^So am I......!

Sorry for the delay all...

In the next couple of days I will have cleaned up my install a little and will provide some details!

Suffice to say that during the run I did in testing was mightily interesting indeed

Right.

I've been tinkering some more and have a dilemma:

The uprated throttle body will only install at a 90 degree rotation to standard, as the wiring is approx. 1 inch too short to get to the plug on the TB in a normal orientation.

Does anyone reckon that installing at a 90 degree angle would affect things in a major way? Should I go and start unlooming the TB cabling from the injector rail and re-route, or just twist the TB 90 degrees?

Had the TB on at a 90 degree to test whether it worked, and it did - was more concerned that idling was rough though but unsure as to whether that had anything to do with the rotation of the TB or not.

C

Edit: I should spend a little more time researching. Confirmed that orientation makes no difference via a golf mk3 forum topic which tested the effect of diff TB's against performance - some of the results made interesting reading.

And as such... As soon as I pick up some hose clamps i'll get a TB adjust done and take some snaps

Sorry I think I might be misunderstanding what you mean, do you mean reinstalling the throttle body on a 90 degree elbow? Or do you mean just turning it on it's axis? These no reason why you cant turn it on it's axis but bear in mind the effects of the throttle plate channeling air in a certain direction in the plenum.

That's what I meant - turned on it's axis at a 90 degree angle.

The wiring itself is 1 inch too short to have in the same orientation as the original TB - but from what i've gathered it shouldn't make a difference - just wanted to make sure.

I'll have to do a bit of long-term monitoring to make sure there's no adverse effects. I could un-loom the TB cabling from the rest to put it the other side of the TB - that would give me enough if I have to. No big deal really.

Personally I would try to put the throttle body in the same orientation as original if possible, at least in your case you don't needs to worry about throttle cables or brackets, wiring wise I would try and do what you have suggested split the throttle plug from the other wiring and relocate it. If you are lucky you won't need to extend the wires..

If you do need to extend the wires I'd suggest going to the scrapper and cutting off the throttle plug from another vehicle leaving a good length of cable attached to it, then butt splicing them to your exisisting loom. The best ones are the transparent heat shrinkable butt splice terminals, you Don't even need a soldering iron for them, just strip the wires shove them in, then heat it up with a hot air gun and when they are hot enough the internal solder melts and flows around the wire then the sheath of the splice melts round and forms a waterproof seal.

Like this.

Dr. Coates...how is the throttle body transplant working out?
