better be a good machinist to make those ITB's work. IMO they're very very nice but not needed to have a good responding motor. There was a setup on Ebay for the Neon's that had 4 52mm dodge TB's welded to the manifold and hooked together properly. There was a thread about them on the car too on neons.org somewhere. Looked pretty sweet. Guy made decent power for his level of mods with them too.
