Nitrous?!
What pulley combo are you at to see 22 psi on the 2.3?
Was this car for sale on Ebay, a while back? I remember those wheels with the red stripe
the 3.3 would be cool and unique but i would not go that route as they are no longer in production. votech is not even offering replacement parts and there is a limited pulley selection.
2.9l is the best choice.
