Actually, you CAN beat the power of the Stealth R/T 3000GT SL - 222 isn't that great considering their huge weight. They are REAL porkers. Extremely so. That's why their handling at low speeds is so notoriously poor.

Prelude... 300ZX, maybe? Even the n/a ones have some grunt. 240SX isn't a horrible choice... and you can always do the ubiquitous motor swap later if you don't like the truck engine they tossed in there stock.
