yeah, theres a 4 cyl model.. but i dunno which engine it is.. but basically, thats just installing a turbo kit..

from my experience with the new 4 cyl though, its really weak and not very potent feeling.. i wouldnt even bother modding it.. besides, converting a NA engine to turbo ends up costing more than just buying the whole turbo engine to begin with..you could probably buy a complete 4g63 with turbo for 4500 i think, but it would cost in the 5k range to put a turbo kit on a NA 4 cyl.. you gotta consider.. you have to buy the turbo, get a downpipe and exhaust manifold fabricated, ecu work or engine management, intercooler, BOV, possibly a wastegate ( if the turbo you're using doesnt have an internal wastegate ).. and a lot more.. perhaps rings, pistons and rods if the stock engine isnt strong enough..
