Hi there,
Just a note to introduce myself - I'm in Seattle and I have an '84 SR5 pickup that's getting a new engine, hopefully by the end of next month. It's an '84 22R block with a 20R head, oversized valves, mild cam, weber 32/36 carb. The idea is to make a very strong daily driver that will get good mileage. I work construction which means sometimes it's a long commute and this will be my main driver, so I'm setting it up for mainly on-road driving but still offroad capable so I can go camping and fishing with no problems.
Only mods so far are FJ40 front brakes and the truck came with some decent 15x8" aluminum wheels on it. The dog didn't come with it, but I think he complements it nicely.
It needs tires, so I'll probably go with 31s and hope the new engine will have enough torque to pull them without feeling it. (It has 30s now). I'd really like to do 32s and put in some 4.56 gears, but no money at this time for that.
I want to lift it 2-3" so am looking at OME springs but would like other suggestions as well. Want something that will raise it up a little bit and give it a decent ride. Also looking for shock recommendations.
I've been building V8s for years and worked at a machine shop for a little while, so I'm no stranger to the ins & outs of an internal combustion engine. What surprises me though is how little hard technical data there is available for the 22R engine. I've been searching all over the web and the kind of info that's available to the V8 crowd just isn't out there for these engines, which is kinda weird considering how popular they are.
For example, no one seems to know what the rocker arm ratio is. One source says 1.547:1, another says 1.457:1. Which one's right?
Also, extremely hard to find port volume, port length, and flow data for the 20R & 22R heads. The volumes & measurements I can take myself, but don't have a flowbench. This kind of info is very important when selecting cams and performance modifications if you want to build a combo that really works. There's a lot of marketing hype out there surrounding these engines and most of it falls into the "bigger is better" fallacy.
Anyway, as you can tell I get a little carried away at the keyboard. This is probably overdone for an intro, but oh well.
Looking to make some friends out here in Western WA and do some wheeling as well as mine all the good tech info I can out of this site. Oh, and I promise, whatever I come up with I'll share with anyone. I'm compiling a database of information about the 22R that I can hopefully put online one of these days.
Cheers,
Will
