Hey,

How much work would be involved in swapping a 32 donk into a bora ? I imagine the Engine obviously, but shouldn't nearly everything else bolt right up ?

Once in, it would need to be engineered and than reregistered ?

i think tassie gti has a r32 donka for sale.

Well the most basic explanation of the 3.2L is that it's just a bored out version of the 2.8L isn't it? Therefore as far as engine swaps go, I imagine it would be pretty straight forward. In terms of the ECU tuning though, that could be a little bit more complicated due to the differing natures of the beasts.
Also you'd probably want to look at a brake upgrade as well as this would probably aid in engineering.
Cheers,
Trent

That's why I am enquiring :) Sell my bike and buy the 32 Engine.

I think everything should bolt up, just need to get a zorst. And yes brakes would be good to :) and I am busy fixing up the 80 as a daily so if I do this... :)

i reckon it would be cheaper/faster speccin' up your 2.8 vr6.

ie, rebuilding, headwork, aluminium oversize pistons, cams.

it'd drive like new and prolly be faster..

regardless you're looking at 3 - 5K IIRC from someone else previously inquiring about something similar

:duh: just supercharge your motor.

sorry guys but i dont think there is any need for a brake upgrade, the 3.2 aint thatmuch faster thanthe vr lump, plus the bora brakes work just fine
its when you start breaking the power to weight issues then u upgrade..... or when u just have bad brakes

Isn't the difference about 35hp? The Bora weighs less so that will be felt even less again, as jayjay said a nice exhaust, cams and a suitable tune will do more than bridge the gap.

Have a look here http://forums.vwvortex.com/zeroforum?id=42 at the 24v VR6 thread for some ideas with specific modfications and technical details.

With regards to the brakes I was more making reference to a brake upgrade helping with getting it engineered. My warped view of the system is that if you have upgraded the engine so to speak they will be inclined to like you more if you have done that as well. I'm probably wrong but I have little faith in acutal common sense and engineering being applied as the whole adr system seems to ignore those principals anyway anyway.

and then weld the boot on? :D

I agree though. Supercharge the 2.8!

mmm. honestly, it's a overly expensive, minimal-net-gain venture to swap in an r32 motor..

It would be an easier job with a front cut and all the stuff you need there. Just buying an engine is fraught with potential problems.

mm. but mk4 r32 front cuts wouldn't be cheap/come up regularly.

I guess the concensus is not a good idea than :) :brutal:

I will keep thinking, but yes would like to charge !
I like the idea of keeping the Bora looking stockish and upgrading it's ability.

If i had the spare cash id do it in a heartbeat myself,the main selling point for me is i plan to supercharge anyway,there is a hell of a difference between a stage 1 charger on the 2.8 (around 280) to a stage one on the 3.2 (around 320 or 330) plus the fact that the bora is a good bit lighter equals fun city.

Plus some people prefer the understated sleeper look of the bora over the more in your face R32 styling.

I ended up buying a 2.8 VR6 24valve......only because i couldnt find a R32 motor:duh:. I would still prefer a R but my project only weighs 650 ,700kgs.
I agree with Treza...bigger motor bigger brakes and 30 odd hps more is alot.

I still have that spare race engine here which was offered to you so you cant say there is no R32 engines in Aus . It was dynoed at 297 hp on an engine dyno in Germany and its going for $8k as a long motor .

I have always wondered, long motor = ???

im pretty sure long motor = motor with no ancillaries i,e, no manifolds, alt, a/c etc etc.

short motor = block with no head and no ancillaries

297 horsepower from the 3.2 is very nice indeed. But at $8k, ouch! What has been done to it?

Why the terms long motor/Short motor ?

As Pedro said:

You can add or remove a few items from either definition but that's basically it, oh and 8k is reasonable for that engine considering it was a racecar motor and has had work done to it...

I did see that Pedro had posted the info, but was inquiring as to the origins of the name or the connection's to long/short :)

because a short motor is just that, its shorter than the long motor cos it doesnt have the head, its basically just the block and internals.
the long motor has the head still on it so its much longer.
thats my understanding of it
