Damned good question. Some good answers also. I am doing a 2.3 Turbo swap later this year. Check your local wrecking yards I just aquired a complete 84 T-bird 2.3 turbo coupe engine for $275. This is probably the best and least expensive way to go, HP to dollar ratio, if you would like to keep the gas miliage of the 4 banger and still get more power.
