Does any one run one on here ?

I have a premier edition and decent turbo kit, but no doubting doing it. Ie a waste of money before I get it all done
 
Depends what you want, supercharger if you want to be able to boot it round bends/back roads with way less torque steer...
Turbo and a posh diff if you just want straight line, but it WILL still torque steer like mad/never put the power down regardless and you'll end up running boost by gear, which will make the power you're making limited in most of the rev range thus pointless over a supercharger...

Turbo'ed ones are genuinely terrifying in corners under throttle/very sketchy, I know a fair few people with them and they're really only go for blowing the tyres off and showing off laughing in a straight line whilst pulling all over the place.

However, it also depends what type of supercharger you'd want, as obviously ideally you'd want a N/A style instant power belt driven type, which are very hard to find/they don't make anymore, like the Jackson Racing setup, which isn't intercooled, so heatsoaks like crazy, thus looses power, Rotrex etc are all building boost style top mid-top end power style superchargers that work like a turbo, so again not ideal with it coming in like an explosion....

I did consider it many times on previous builds but I think a K24 frank is the better option with a solid 300ish bhp N/A.

I think turboing a K20 can work quite well but not in the original cars they come in imo. In something like an Elise, E30 or whatever RWD then yeah but in the FWD of the EP3, DC5, FN2 etc then i think it's too much.

You'll need a very trick diff to make any use of the extra torque. I had a wavetrac LSD in my old DC5 running around 235bhp and imo for me that had too much 'torque steer' feeling even being NA with the way a plated or semi plated LSD pulls in a FWD car is pretty scary for road use.
 
A lot depends on the turbo as well, id always sacrifice outright power for a smoother delivery.
