Holley/Webber 5200 2bbl's work well and they are about $150 on EBay. Several places on-line have carb adapters for them. A better approach is to have a machine shop mill down the carb flange on the intake manifold and create a flat surface on the intake "log" manifold to which a fabricated adapter plate can be mounted. Holley 2300 2bbl carbs also work well, adapters are also available, but again, direct mounting to the intake manifold is the better option. A carb with about 500 CFM for a boosted/turbo application or about 350 CFM for a N/A application is required. |

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 toconnect 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. |
