Re: G60 Engine mods??? !!! (bigkawim)
There's an infinite number of possibilities.
The most common mod package is a "Stage 3 Kit," which consists of a chip, pulley, and an FPR. Add on top an exhaust/intake, and then an ISV re-route or boost check valve. This will total $400-$750, and get you appx. 165hp/175tq @ wheels.
A Stage 4 Kit adds a different chip & a different cam than the Stage 3. Cost is the same. Expect appx. 175hp/185tq @ wheels.
Then there's the Lysholm supercharger option. Cost is $2,699. With the same accompanying mods and a high boost pulley on the Lysholm charger, expect appx. 185-200hp/200-210tq @ wheels. You may also want to invest in 30# injectors at this point, $185 or so.
Turbo conversion. Cost varies depending on your choices and accessories. It can be done (bare-bones) for $1,600. However, to do it right, and with a decent turbocharger, expect to spend $3,000 once the correct accessories and electronics have been purchased. You will need fuel system mods, a specially mapped chip, and you may consider an upgraded intercooler (not necessary though.) Power will vary depending on the setup and boost levels. Expect appx. 175-225hp/210-260tq @ wheels.
Headwork will make one hell of a difference at 15psi and beyond. So will a specially tuned exhaust system (2.5" would be nice at that point, to maximize the breathing potential of the high boost motor with headwork...2.75 wouldn't be out of the question depending on your preferences). Combine the headwork and exhaust with a racing downpipe (also 2.5")...expect another 30hp from those mods in unison, easily.
A decent ignition system and aftermarket coil will (believe it or not) make a difference you can feel, once you're Stage 3 or beyond. Cost will be $200-$350. Power gains will be in the ~10hp range.
Stand alone fuel management? 1.9, 2.0 or 2.1L conversions? Limited slip differential? AWD Syncro setup? It's all possible. What do you want to spend?? http://****************.com/smile/emthup.gif
