Well, enough people have voiced about the whole modding a leased car and frankly that is none of my business, I'll try to simply answer the question lol.

I'd go with MAP, they have built dozens of 4b11's now, more than anyone else local, no reason not to use them.

A 2.0L setup is probably the most reliable. It requires less tuning to get right. If you want easy, buy a new shortblock and keep stock sleeves and do drop ins. You will need an entirely new oiling system for sure. Plan on oil pump and oil cooler for sure, probably get a new oil pan too as DB could never get all the metal specs out of mine. Pick up some metal Hyundai pulley's too. Keep it simple, stay on pump gas, stock turbo if you can, otherwise small upgrade like an EF2, EF3. I am saying keep it simple because then your fueling system can stay simple. Keep the fueling system to a wally 255 drop in if you can and some 1000cc injectors (prolly ID1000's or FIC11000's). You could probably do E85 if you really want to on that setup if you stick with an EF2, then you can get an easy 450whp.

keep the head stock and everything else you can stock too.

By the looks of it you seem pretty set on building the motor since mitsu won't cover it. I can't blame you, seemed silly to me not to build it if I was replacing the motor but others have a decent point. So my advice is keep the "while your in there" to a minimum.

Manley rods or Map X beams too, ACL bearings all around, deck the head, new headgasket (which if you stay 2.0 you just get the entire mitsu gasket kit, plus mivec 0rings which don't come with the kit I think) and get some JE or Weisco pistsons, if weisco get the 1400hd's or JE ams spec ones.

GL!
