your biggest shortcoming up front is the auto.
I would talk to Bwinlkers (sp?) he has a STOCK INTERNALS 07 d20 hatch, header, IM, gutted to the dickens, running mid 12s on 100 shot spray alone with 22" slicks. Unfinished tune. He was running a wet 75 shot untuned for a long time too (Before the IM).
