how about a turbo for carberated 4clys? is that possible or do you need to go with fule injection?

LC has a turbo header for efi but whata bout carbs?

That can be done just as easy as fi.However its much nicer to have turbo with efi..I am not a fan of turbo motors for rock crawln anyway..almost pointless and turbo exhaust temps get pretty high..for higer speed driving is great,say maybe for the dunes...

a turbo is pointless for rockcrawling since the turbo doesn't kick in until a high rpm is achieved. a turbo would be great in the sand and/or driving TO the trail.

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.

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!

I agree if its going to be an off road truck but... In my case its going to be 80% on the road and light off roading. I currently have a 22R and its on its way out the door. I am looking at swaping the 22RTE motor in, to get rid of the carb and get a little faster. What parts other then (motor, ecu, wiring harness, and things attached the the engine) will i need to locate. I know that this may not be a popular off road person swap but i need a truck that can go up to 65MPH and stay there.
thanks

:nerv:why not supercharge it :dunno:i emailed carl at LCengineering and he said they DO have a supercharger for the little 4banger. its not in the catalog or at least not mine

, but he said it didnt interfere with the stock a/c compressor :~~: :~~:

Subject: 20R supercharger

hey is there a supercharger for the 20R using a weber carb?? and if so can the stock a/c compressor stay put??

his reply

Yes, the blower system for the 20-22R uses a 38mm Weber....and the stock A/C can be retained......Carl

I understand what you are saying but I really want to get rid of my current motor all together and start fresh. I have access to larger turbos, intercoolers, fuel components...etc... so I'd like to stick with the turbo motors. I like the 22RTE because it will be a direct fit and should not be all that much work. Im an not concerned with turbo lag at all since it will be mostly street driven. I am also not concerned with the AC even though it would hook up to this motor. The other thing is that i want EFI, no more carb troubles.
Thanks

May be swap a r151f trans and 23 spline t-case or convert your t-case to 23 spline..With a good adjustable wastegate and intercooler you could all but get rid of turbo lag..

Bunn's racing (Bismark,AR) balanced my 20R so smooth at 600rpm you can sit a cup of coffee on the valve cover and have to bump the truck to see a ripple :~~:

If you wish to use the NA flywheel/clutch, then nothing else is needed.
You could even use your L-series transmission, but it would only last half a year behind a Turbo, if that. Worst is 5th gear with a Turbo going uphill.

Say goodnight to your tranny

A stronger rear end would be recommend as well. You can directly swap in a Turbo 3rd member or a V6 third member (1989-1995) (1996+ non-electric locking [requires some grinding])

I dont know where they expect you to put the A/C compressor!!??

YotaYota · « **Reply #19 on:** Aug 28, 2004, 06:48:16 PM »

dosnt the size of the turbines play a part in when the turbo spools up

small turbo = spool up fast = more bottom end, big turbo = spools up slow = more top end, a free flowing airfilter and exhast helps the turbo spool faster as well

right,

but for rock crawling a turbo is about as useful as tits on a boar hog,

but you would have the impact power on the highway to and from the trail, but you better use a "R" series tranny

i'd like to see a turbocharged 20R...mmm...20R-Z...

they have 8.4:1 compression and a pretty stout bottom end. i'd be mainly worried about the pistons though since they're cast, but the rest of engine is pretty much bulletproof. i'd love to have something with just a "little" more grunt than a 22R, maybe a turbo could be a good way?(then again, my engine has 300k on it and while it has no bottom end with an L43, 4.38s and 32" tires, it'll pull hard to over 5000RPM with my weber carb)

maybe i just need to save my pennies and buy a late model 22R and rebuild it like new, i'd build a 20R but the exhaust studs were tapped crooked and oversized on my current head, and the one in my back yard is an early model so it can't use my stock power steering...
