I think he already made it clear that he's not going for a transplant at all...well i understand what he means actually...i myself got a 4G15 carb satria which goes into an underpowered class engine producing a mere 79hp on stock but i have already made up my mind to mod the engine to the max while still retaining the NA identity...to me, to be able to turn a baby into a monster is the greatest satisfactory for me no matter how much i have to spend for the process...can u imagine the fun and the relieve for every single cent u've spent...yes...people might say that ur stupid, waste of money and time...but that doesn't matter at all...it's the thrill that is undescribable to a few person...so everything depends on the will and the budget...i say go for it...
