Let’s just get this out of the way, now. The sport compact market is a niche that many publications like ours (that focus heavily on V8-power) tend to ignore. Of course we’re not like any other publication, and we feel that a DOHC 4-banger tuner with boost can be as equally mouth-watering as an LS-powered Camaro or Firebird – with the right parts, of course.
Whether you’re looking to simply build a quick daily-driver or you want to get serious about small-displacment performance, there are plenty of outlets for you to choose from in finding speed parts for your GM pocket rocket. One place that is often overlooked is General Motors themselves. GM’s in-house speed shop, Chevrolet Performance, offers an excellent selection of performance and cosmetic items for you General Motors vehicle.
From crate engines and camshafts, to simple bolt-on performance and appearance packages, you can find just about all of it from Chevrolet Performance. You can score Chevrolet Performance hardware from licensed retailers, like Scoggin-Dickey Parts Center or Pace Performance, too.
Having making a name for themselves as the go-to for LSX engine blocks, crate engines, and other hardware for our favorite V8 engine – and even complete race cars, like the COPO Camaro – Chevrolet Performance’s line of sport compact performance is sometimes forgotten by even the biggest fan of the Bow-Tie. To rectify that, we hope to shed some light on these parts. So follow along as we dive headfirst into the Chevrolet Performance catalog to get a closer look of what’s available!
Crate Engines
2.2L L61
The 2.2L L61 Ecotec was the first in a long line of the series. Initially launched in the MY 2002 J-body and Saturn VUE, it ranged from 138hp-145hp throughout its lifespan. It was also the base engine in the Cobalt, ION, HHR, and briefly, the Grand Am. Offering a solid bottom end, it was boost-friendly from the factory. If you’re looking for a brand new replacement from GM or you just want a fresh start in terms of a N/A Ecotec platform, this is perfect.

Stage 1 Performance Upgrade Kit:

Stage 3 Performance Upgrade Kit:
So you want really want to get serious about your RL or your ‘Balt? You won’t miss your A/C? Well then, Stage 3 is for you, my friend. Taking Stage 2, and turning it up to 11, you get an even smaller supercharger pulley (76mm), a 2-pass intercooler end plate, and a unique PCM that includes a calibration for the smaller puller, an adjustable rev-limiter, a 100-octane mode, and a nitrous control algorithm.
The rev-limiter is adjustable from 6750-8000 rpm, and is adjusted by pressing on the throttle pedal with the ignition on and the engine off. At about 50% throttle, the tachometer will show the current rev limit. If you press the throttle further, the limiter will adjust the limit in 250 rpm increments.
GM claims a full 248 hp on the 93-octane tune, and when running on 100-octane, you’ll be pushing 260 hp with no other mods than the Stage 1-3 kits. Once you get to this point, however, they (and we) recommend an aftermarket low-restriction exhaust system. With a calibration and rev-limiter adjusted for a 50hp shot of the go-go juice, we would take advantage of it.
