Maximum size engine you can swap in.

I think we've all read the regulations on the maximum engine size we can use under table LA1 of the VSB's.
I also think we've failed to read the paragraph right before the table in the VSB.
I've come to conclusion that the MB isn't restricted in what size engine you can fit, other than physically.
The table states it does not apply to NA or NB1 category vehicles.
The MB is a Category NA vehicle.
I have an email from my Engineer agreeing there is no actual limit, rather the engine swap would be restricted by good engineering practice.
I asked what I could do with an early Carry and he said he would engineer a normally aspirated small capacity V6. This means you could fit a Eunos, Suzuki or Mazda V6 into it. It would also allow use of VW V6's. Most of these are 150-200FWHP territory.
I then asked about a stock turbo 4 and he said OK.
If I did a 4 cylinder swap it would be a 4G63 from a Mitsubishi Evo and couple it to a rear wheel drive 5 or 6 speed transmission. With a computer tune only I can get that up to 200KW at the wheels. Laclan's Evo VIII has 206 at the wheels and the engine hasn't been opened up.
We're currently looking at our options but a Mitsubishi Clot Ralliart swap looks like it would fit in an MB without too much stress. Only 115KW in stock form. Oh, that's only 98KW more than a stock MB!
What are peoples opinions on this?
