If you're gonna go with a turbo get a 1JZ. That'd be sweet, cheaper than the 2JZ, which would be the ultimate in an MkI, and produce way more power than a G series engine. I don't understand what the point of a 1G-GTE engine SWAP is as it only has 210 HP and is clearly pointless. (I may be wrong here) The 1GGTE wasn't even in America, so good luck getting parts. With small displacement, and, after a little searching it looks like aftermarket support is limited, doesn't look like this engine has much potential. I haven't seen a 1JZ swapped MkI, 2J & 7M have both been done. 1JZs have more aftermarket support, more information, more power. Why use a G series? I'm just curious, not trying to be critical.
