just wondering what the easiest and most powerful engine conversion for a corona would be? bearing in mind i want the car off the road for a minimal amount of time. i was thinking about a 2.5l 6 cylinder twin turbo, but how hard would that be to fit?
cheers in advance.
Assuming you mean the 1JZ-GTE, forget it. Having witnessed a 1G-GTE conversion, you won't be fitting the larger 1JZ-GTE without fairly serious mods. The 1G conversion isn't too hard, but still no walk in the park.
your best bet would either be a 4AGZE bottom end with a 20V head and a GT2530 turbo with a w-series 5spd, an SR20DET and 5spd, a turbo rotor or if you have a bit of money and want to stick with the toyo theme north-south a 3SGTE with a w-series gearbox for something different. steer clear of the sixes unless you know you physically have the room.
you have many options out there dude. how fast do you want to spend?
