Toyota's are sexah!
JDM4G63T many older Toyota's have pleanty of room to work in the heads, but Toyota also just... Goes crazy conservative with cam profiles. In many cases, mild cams can provide big gains, without loosing anything compaired to stock cams. That goes double for all the old 12v 6 cylinders.

On the 22r-te, richen your AFM cog abit. Won't do what a piggyback will, but it'll open it up a bit. You can do the large body Denso AFM swap also if you feel like playing with it. That'd be worth it on the GT28 & adding boost.

Toyotas are the sex. I can't say the same for my old DSM (doesn't stay moving). That thing went down more than a 2 cent hooker. I got hooked on these yotas once I found out how all of them were well engineered, parts were semi cheap (Landcruiser is the exception) and they hold up to the test of time. No wonder why Toyota is bigger than GM...hrrm.

I have done some research on aftermarket cams, MAF offers a "RV" cam for the 2F, some say it may work in the 3FE. I'll definetly look into more throughly before I finish the motor...

On the 22RTE, I would richen the AFM cog, but I have to vent the BOV (Tial 50mm) so it will cause a super rich condition after the bov open/closes. If the rpms fall back down to idle, it will be too rich and want to stall. I'll have to use the AFC to lean it out at low RPMs, and richen it when it goes into boost. I'll be using a SAFC 2 plus a three bar map sensor instead of the TPS to measure load. This will allow me to "tune" two different maps, one when it's in vacuum, and the other when it's in boost. I'm going to try to use the stock AFM, put 20%-30% larger injectors/ adjustable regulator. I should be able to trick the AFM out of fuel cut with this method. Thanks for the suggestions, I'm always open to new ideas!

Damn the BOV. If you really want to get into playing with fire... You can adjust the AFM's idle by-pass screw, throttle plate, and TPS. But you'd be sacraficing the idle for it.
You could buy an smt6, and above the safc you would have, real dual maps (in your way of thinking 4 sets), scale it on the rpm, TPS and a map sensor, or just off 2 sensors. Ignition control scaled on boost, extra injectors/wastegate, and either tune the afm, or the lambda sensor.

I'm a much bigger fan of just adding an injector<s>. It's no more work than pulling intake & fuel rails off, and there is tons less work tuning them. I've also swapped myself & a few others from doing that & tuning the AFM, to extra injectors + lambda control. Scale that o2 sensor to richen it up on boost & lean the thing out off-bost/low-rpm, and pick-up some economy.
You've still got one output to trigger a relay to do whatever. Sprays, water injection, anything under the sun that's on-off.

If you just want a little more fuel cheaply. Toyota cold-start injectors are about $2-5 on eBay, and a boost pressure switch is like $15. They make for a good "just in case". Especially since most older Toyota come with 1 CSI to begin with.




Sorry, I'm just not a big SAFC fan.

Quoting myself just to reiterate the badassness of your projects. Damnit I want one of those!!

Man I didn't know the cruisers had a solid font axle. Just would have guessed it was independant!!!

I'm pretty sure US cruisers are independent. They still sell O.G. landcruisers in Africa and Australia, that have solid front axles. Check out the options, they are pretty badass. They call U.S. landcruisers, Prados.

(edit)
Well the site doesn't show the options? They come with that 4.2L diesel, a turbo diesel, or a gasoline engine. The have different locking hub and differential options. And different tranny and gearing options. I wish I brought a catalogue back from Tanzania. The salespeople there thought I was a nut....spent about an hour crawling underneath the floor models.

Here's a cool link

All US models of the LC were solid axle. 40 series through 100 series all have the 30 spline solid axle, which is the biggest birfield axle toyota makes. I believe that 80 through 100 series are all coil sprung solid axle. The 1HD turbo diesel motor is bad ***, it's basically the Yanmar boat engine mated to a 5 speed tranny, if only they sold that motor/tranny in the US. Check out www.ih8mud.com more information on the cruisers if your interested...

sick cruiser and even sicker truck. i planned on turboing a 85 toyota pickup but dropped due to rediculously good deal on a honda. yeah all cruisers up to like 98 or 99 were solid axle with coils all around, a really low range, enough creature comforts to make a benz owner comfortable, and did yours come witha locker? i know some did but not sure. they make gangster toyota four door hilux trucks with solid axles in europe... i would sell my soul for one..

JDM4G63T

No lockers from the factory, I have an ARB air locker up front, and a power traxx in the rear. I have seen the hilux four door trucks they are pure sex.
