That can be done just as easy as fi.
Actually a Turbo on a Carbed engine is alot more difficult. You have to worry about the boost pushing the fuel back out the float and into the gas tank. So you will have to pressurize your fuel system in order to get fuel out of the jets.
Also, I would recommend using a MSD second hand knock sensor to monitor your timming since the carb'ed engines have no ECUs nor Knock sensors to help prevent detonation.
a turbo is pointless for rockcrawling since the turbo doesn't kick in until a high rpm is achieved
This is true however, a Turbo provides alot more backpressure than a NA (Normally-Aspirated) exhaust system, so the engine should, in theory, lug down and idle better, but this is counter acted by the fact that stock Turbo engines have lower compression (7.5:1 vs. 9.1:1) so now your back to about a stock NA setup.
Now Idealy, you would want to run like a 9.0:1 Compression + a Turbo thats pushing about 4-5 Lbs boost with an Intercooler, or about 6-9 Lbs boost with Water Injection. I dont know much about the bottom ends of the 22R's but I doubt they are very stout. Stronger rods would be recommended. This setup would provide great power + great back pressure for Rock Crawling. Plus it would be alot quieter than a NA engine with a header and free flowing exhaust system; with alot more power to boot!
Marlin rebuild my buddies Turbo with the TEC Turbo, and I went up a rather steep highway section heading up towards Dusy and Bald Mtn. and I pulled 4th gear at 80 MPH just using 6 Lbs boost (out of 10 lbs boost). So I was not floored and could have gone more, damn morals.....
But all of this talk and I know that when I build a Rock Buggy it will be Supercharged. HA!
