Yes, a bone stock 1G 6 bolt engine can fairly easily get you into the 11s, no need for crazy motor work. It'll do it with the stock cams in it too, as long as they're 5-spd cams. If you want to upgrade the cams, that'll definitely help the midrange and top end, but it'll hurt your idling characteristics. When I first ran 11s, the engine that was in my car probably had about 90K miles on it. I would say my car was making at most around 400hp when I first ran 11s, though I never dyno'd it to find out. The first car that I had that I dyno'd was the Colt, which had a setup very similar to the Galant's setup when it ran 11s, but it had a Frank 3 turbo on it versus the 20G that was on the Galant, and the Colt was using a side to side Spearco IC like the Buschur core instead of the top to bottom Spearco that I had been using on the Galant. I actually think that the 2-221 Spearco (top to bottom) flows more air than the 2-178 (side to side) Spearco, but it just looked like crap in the front of a Galant, so I switched. Having a 20G turbo will definitely help run 11s, although Doug Thomas was able to go 12.1 on a 16G in his Galant. The stock engine will hold a lot more boost than you think. That Colt Turbo that I had was using a 70K mile JDM engine in it when I dyno'd it, and it held 27psi of boost on the dyno to put out 383hp at the wheels. True, the 20G will help more if you're flowing more than 20psi, but it can be set up to be a GREAT street turbo with the right combination of mods; those mods being a nice intercooler, good piping, a nice big exhaust, bigger injectors, and a fuel computer to control those bigger injectors. The single biggest help to getting any turbo car to run fast is to spend time pressure checking the intercooler piping system to find and fix leaks. I do it like this: block off the inlet of the turbo, and then find a vacuum line that comes out of the intercooler system somewhere and I run compressed air through it to pressurize it. Just listen for the familiar "pssssss" and follow it to wherever is leaking. It works, trust me. I just realized that this is getting really long, so yes, I do think a stock GVR4 motor is strong enough to run 11s without being built. Many people have proved that other than me, so I'm definitely not a fluke.
