Agreed, I want to get a look at this thing as well. I love the idea of the toyota motorhome/campers . I honestly dont know how the drag themselves down the road with the old 4 cylinders though? I'll admit one time I was driving 70mph down the highway in my 22r pickup and a old yota motor home flew right by me in the other lane . Then again, who knows what was under the hood. Id love to have one with a 3.4. 4xChinook4, what kind of mpg you getting? Oh and
I am actually getting ready to do a turbo/efi swap onto my 20r/22r hybrid. We are just cutting the intake flanges off an old manifold and welding runners up with fuel injector and water meth ports with a 3.5'' plenum coupled to a 60mm throttle body... This will be going in my 78 2wd yoter. Get to posting so we can see some pics of this thing!!!!
Yes sir!!! Round ports intake and exhaust in the 20r head. Yes carb is always much more simple to keep running and more cost effective. BUT, if you are going to add forced induction to the equation, I prefer EFI... Unless you supercharge it, which I have found to be very expensive and can cause overheating issues... Turbocharged on the other hand can allow you to run an intercooler for cooler air temps/less chance of detonation/more power. I'd prefer EFI or propane with this, although I don't' care much for propane... It stinks and doesn't have the lubricity characteristics of gasoline. You can purchase blow-through carbs but they are not cheap and then again limited on fine tuning abilities in my opinion...My setup will consist of a heavily ported the 20r head, 48mm intake valves/seats, 40mm exhaust valves/seats, pro valve guides, dual valve springs, titanium retainers, Crower stage 3 camshaft, and adjustable cam gear for the top end. Then the early 22r block will be 8.5:1 compression, .040 over forged slugs, chromoly H beam rods, clevite bearings and ARP everything. I have a 22re harness out of an 89, purchasing megasquirt pnp ecu which plugs right in to the harness then I'll have full tuning access! After I get this engine built for my father I will be diving into this head first! Will be the most modified 20r/22r/22re series engine I've ever had.Right now its around 11:1 compression, dual weber 45mm sidedraft carbs with a cannon intake, same cam as above, single valve springs, stock valves, and factory hardware. Needless to say, it pulled HARD! Rubber through 3rd no problem. But to my dismay, the PO who rebuilt it did a really poor job, plug on main oil galley came loose and developed a slight knock after oil pressure fell off on the way home. It was a bummer but at the same time I've always wanted to build the out of a 20r/22r hybrid and boost it.You can do anything from wild to mild, just depends on your tuning/fab/wrenching skills, access to equipment, and how deep your wallet is... I'm curious to see your build!
I this build! Did you start talking about this over on I H8 mud? I will be watching this one.
(we all Lloyd know this;) )a 3rd pumps about 150,
