Depending on the engine, mounts, ecu, wiring looms, shafts, hubs, brakes, suspension, body mods, dash, electronics etc etc
The MA09ET engine isnt a straight swap either
The only one that is straight no messing is the MA12, if it hasnt already got the 5 speed with it then yes you need a 5 speed really, bolts straight on, you could keep the ma10 - 1.0L and put a 5 speed striaght on...
I put some skin sills on my first K10, they were from my local bodyshop...cos nearly £400 to get them welded on tho
