Just learned something... the same AR-5 manual that we're swapping into my VX was also used on the Pontiac Solstice GXP. That car featured a dual-turbo 2.0 L I4 Ecotec engine that made 260 hp and 260 lb-ft torque while getting 19/28 MPG. The VX is heavier by almost a thousand pounds, but you'd drop a good chunk of that just by going from a V6 to an I4...

So since we know an AR-5 mates to an Ecotec engine is it conceivable that you could swap that engine instead? Discuss...
