So I get asked this a lot: "How much power can I get out of turbo charging my "stock" 22re?"

In the past, I've had to reference some somewhat undocumented results, as I've never tried it.

I've been troubleshooting dyno and tuning issues with my motor. As it turns out, my pistons were incorrectly designed (someone typo'd my head CC) and I'm running ~9.4:1 compression ratio motor.


I've been driving this thing successfully for about a year, but haven't had much luck pushing it harder than about 10 psi.

I finally got it on a dyno (which lead me to chase the compression problem) and the results (dynojet):

1) 130 rear wheel HP / 188 ft/lbs torque.


Sounds like stock?
Typical results for a NA 22RE are 88 rear wheel hp/ 115 ft/lbs of torque.


Actual flywheel HP, approximating a 30% driveline loss (transmission, transfer case, etc): 169 hp, 244 ft/lbs torque. These are the net gains that could be compared to book HP.


Torque curve is good, peaks at about 3500.

Other notes, you're looking a 92-93 octane only. Running on the street (safely) you're going to be limited to about 7psi. Going above that, no appreciable gain as you're pulling too much timing. Want a larger gain, run E85. I haven't dyno'd it, but I'd estimate you'll pick up another 10-15 hp.

I'll scan the dyno in one of these days.. My head is going in for "correction" to adjust for the piston design mistake. I'm going to take the truck down to 7.5:1 CR.
