Looking for more power and speed, any input on installing the SH .18 engine for the Lighting STR?, i'm looking to re-gear it with HPI's 18t/23t Clutchbell and gears, but using the stock 2-speed tranny. The stock VX .16 on 30% is not fast enough, LOL, but I'm not spending $400 + for a new faster car. THX.
