Opinions Needed

I am in the process of putting a turbo on my RS . I decided to turbo it since its almost new, meaning not driven and raced a lot.It has new belts , pulleys, shocks, springs , breaks, water pump, polyurethane inserts , radiator, hoses and a ton of other stuff. I am in the process of buying to Howell Automotive bottom rebuild kit. I am thinking between the 16G and 20G turbo's. The price difference is $300 between those two which is almost nothing compared to the performance difference. This is a 420a with a 20G putting out about 350whp at 20psi.

I wounder how Jake got his RS to what was it, 380whp ? Any one know what mods he had on it? Man I wish he was here to help meeeeee since he knew the best about boosting a 420a.

Sorry I gave wrong website for the 420a boosted engine. Here is the correct one.
