I was going to set up a 2WD with a 4.10 geared diff from a 4WD. This particular one had the 8" rear end with the same spline axles so it would drop right in. This would give you more pick up off the line. Slightly smaller diameter tires would accomplish the same effect.
I took an '85 2wd in partial trade that had 4.10's, the owner had it regeared due to the heavy trailer he hauled for work. With 4.10's and aggressive driving it would chirp the tires in 3rd, of course highway speed was hurt a little, but if you didn't spend long periods above 65mph, it wasn't too bad.While the upgrades you are considering will help some, there isn't a lot of untapped HP in the 22re, which is why no one ever states any expected HP gains. If it were I, I would do intake and exhaust, and possible a gear change depending on what gears you have now, and how fast you travel the 70 miles to work.Might find this info helpful for gear ratioshttps://toyotaminis.com/forum/threads/toyota-2wd-rear-axle-gearing-and-transmission-info.3313/and this calculator for speed in each gear at a certain rpmhttp://www.tremec.com/calculadora.php
BTW, the stock exhaust manifold is a mini Tri-Y header.
... it’s freshly rebuilt about 6 months ago
Hey brodyman0508...Can you describe what exactly was done to your "freshly rebuilt" engine?Gnarls.
I couldn't agree more. Don't waste your money trying to make a 22RE faster. It's as good as it's going to get in stock form. I've throw countless dollars into most of the things you mention doing and never noticed any appreciable gains, just headaches. The 22RE ECU has no ability to learn, it's 80s logic chip electronics with fixed operation. It is what it is. It's actually perfectly suited for a 2wd pickup. That's my advice
I never intended for it to be a race truck or anything.. just more fun to drive.. i bought it for the gas mileage and it’s not great so i might as well make it go faster.
What kind of mpg's are you getting now? You should be in the mid to upper 20's. If not at least id 20's, I would start with a complete tune-up and inspection.While fun, the 4.10's would be a bit to live with on long highway stretches, would either go one gear set taller than what you have now if possible, or run a size smaller tire.
Your #'s are wrong, having run 4.10's with the stock 195/75/14's, I can tell you they are off by about 6-700rpms.
"195/55/16 tires" Gnarls.
hmmmmmm...... not quite! Gnarls.
That isn't stock size, close enough, but your numbers are still wrong, your calculator must be wrong.
My 86 22RE California exhaust manifold is a mini tri-y.The 86 has the "2" part of the 4-2-1 very short. Earlier models (I think 85 and earlier) the "2" part was long.
He posted tire size: 195x55x16 = 24.44” diameterHe posted 55 to 70 MPHBased on that:55 MPH = 2535 RPMs60 MPH = 2875 RPMs65 MPH = 3114 RPMs70 MPH = 3354 RPMsGnarls.
My bad on the tires, missed his post about what he is running. Your new numbers using crawlpedia are better, but still off compared to what I experienced in the real world with an '85 2wd w/stock 195/75/14's(25.68" tire). With that set-up, at 70mph the rpm's were just over 3500 on the stock tach, w/about the same amount of noise level as one would expect from a 22r running at 3500rpm's, and at 60mph they were just under 3k.
