Holley 5200 2bbl's (a licensed version of the Weber 32/36 carb) work well. Several places online have carb adapters for them. Another approach is to have a machine shop mill off the 1V carb flange from the intake manifold, creating a flat surface on the intake manifold "log" to which a fabricated adapter plate can be mounted. The other advantage of using a Holley 5200 is that the readily available Weber 32/36 jets fit this carb. (Any 5200 you buy will most likely need to be re-jetted as it was probably intended for a 4 cylinder engine.) If you decide to go this route, buy one with an electric choke and an anti-dieseling solenoid ('86 Ford 2.3L, for example) and save yourself a lot of grief. |

K&N makes a couple of air cleaners that are designed for this carb. The shorter one will definitely clear the hood, but the taller one may work if you keep the other clearances tight. | K&N makes a couple of air cleaners that are designed for this carb.

Turbochargers have become popular for these engines; a smaller T4 will do nicely. A J-pipe up to the turbo from a factory manifold will work, and is simple to install. | Turbochargers have become popular for these engines; a smaller T4 will do nicely.

This allows you to connect a turbo outlet directly to the manifold in a draw-thru setup. This flange can be found easily from many online vendors with a Google search. |
