Just having a think in work while I'm idle and I've been thinking.  Just got myself a graduate job and making an income finally.  Was thinking about MK6 Golf R's and how they obviously didn't do a V6 version.

The bay of the MK6 is near enough identical to the MK5; and hence MK4 (mounts, etc).  Could buy a MK6 and whack the MK5 3.2 into it for noise, but then it would be all noise and no go.

Even still, the MK4 R engine has a better note; so why not smash that in? 

Boost is more fun though, so why can't you throw an S4 loom and ECU at it so you have controlled boostings on a MK4/5/6 R engine?

Just thinking while I add my income up per month to see what I can afford..

Was purely for a discussion point while I was in work.  I have no real knowledge of either engine as I've never encountered them. 

It's just that I'm getting bored of FWD and wanted a little more.  An S4 has always been my guilty pleasure, but so has a MK4/5 R.  There are various threads about controlling R's with boost, but I thought the hardware (N75) control was none existent on the ECU, so there wasn't much you could do.

You post suggest otherwise. I'll go study the ECU pinouts. I guess with a little ASM you could control another valve instead.

No 2.7t was wideband.
