This is kind of a follow up to my first post:
https://www.yotatech.com/forums/f116...gasket-168805/

Long story short:

1987 4Runner (really nice condition)
Previous owner swapped 22RE for a 20R + carb (no idea why)
Blown head gasket

I'm thinking about taking the 20R out and putting in something else.

A) swapping everything back to the 22RE
B) swapping the 20R for a 7mgte. I can get a rebuilt from a trusted supplier
for about $850. I'd like to have the xtra power and from what I've read it's
an easier swap than most, but I'm not sure HOW easy.
C) swapping the 20R to a 302 for more power, but I'm not sure what I'd be
getting in to.

If I swap everything back to the 22RE what all do I need to buy or make
sure I already have installed (and actually works). Also, what will I ge into
if I wanted to add a turbo to the 22RE? I'm just trying to get an estimate
of what my cost will be.

Thanks guys! I'll try to post a pic of my 4Runner this evening.

I'm leaning toward swapping the 20R with a 7mgte. I've read that it's a good
match up and has plenty of power. Anyone know of a good resource for doing
this in a similar truck/4Runner?

I really appreciate any help you guys offer.

Thanks. That forum is dead, but it looks like a good resource for info though.

I found this:
This guy swapped a 22R for a 7mgte. I'm not sure what else he did, but it has the
power I'm looking for. His tires are way bigger than mine too. I'm running 31's.

Can you more experienced guys help me make a checklist of things that I'll need to
make this swap work? Maybe just something I can start with to get a ballpark figure
of what the project will cost for parts, what I can do myself, what I'll have to get
someone else to do for me, etc.

I'd also like to avoid having to wait for parts to get delivered also so I'd like to be
able to have as many parts on hand ready to be installed. Ya know?

Thanks again! Maybe this thread will be a great resource for others as well.

I've found the answer to most every question I've had about a 5M/7M swap on that site.
Couldn't find the answers to emissions testing- that's all I couldn't find.

there is a ton of info on this site including check list. i am not trying to mean or anything but the search button works really good for every question. you asked. and i might be easier for you to get a complete doner car or google search JDM engines and they give you everything except the 5m bellhousing and the 5m motor mounts that bolt directly to your 22re mounts

I love my factory rte but its a little hard finding them for a reasonable price. You could build your own but it gets expensive quick and factory they are still a little doggy. The 7mgt swap is something that is probably more feasable and you can get much more power out of. Just watch out for the head gasket issues these motors have. Sometimes you'll see some turbo'd trucks and 22rte swap parts for sale in this forum http://www.22rte-trucks.com/simplema...orum/index.php. at least you still have a factory motor setup, light weight and reliability of the 4 banger 22r series motor and alot of parts are interchangable with the re

x2. i would also go with the 7mgte over the other options if you are looking for an upgrade. i've read on several occasions that the head gasket issues is solved with one of two solutions, (1) tighter torque on head (need to do research to find out how much...i think supratrucks has a couple places where it says what it is), or (2) go with a better, metal head gasket. if you are getting yours rebuilt from a reliable source, i would talk with him about his experience with the head gaskets and what he recommends as a solutions.

otherwise.....if you are looking for an easy swap and aren't necessarily looking for an upgrade....i think i would try to source parts for the 22re, assuming the previous owner didn't rip out all of the wiring and ecu.

that's my nickel's worth of opinion.

Thanks for the help guys. I'm slowly sifting through the forums to find the
information I think I need and printing out what I can.

I'm a web designer and internet marketing manager and over the past
couple of weeks I've had a pretty bad case of eye strain from working too
many hours.

I've gotta take a lot of breaks so it takes me a little longer to sort through
threads that get off-topic or just don't make sense to me, since I'm not
really in-the-know when it comes to swaps like most of ya'll.

I'm excited to get this project underway cause it'll give me the chance to
get outside - away from the computer.

Yeah, from what I've read it's one of the easier swaps w/out all the cutting
and welding. True?

I'm thinking about just going with the 7mge - no turbo. I can get one for
even cheaper and I think it'll be an easier install. Plus it still has enough
power for what I need. Do the non-turbo 7mge's have the same head
gasket issues too or is it just the turbo'd 7mge's?

So from what I've read, here's what I need to do:

A. See what transmission I have (I don't know if the previous owner jacked
with the factory trans or not) and make sure it'll bolt up to the 7mge. I've
read that it will and I've read that it won't. BTW, would I do better to buy a
7mge + trans together? Any problems or benefits with that setup?

B. Make sure the motor mounts match up. I've read that I may need 5mge
mounts, but I haven't looked at my mounts to see how to change them
out.

C. Find a 7mge with a/c compressor, power steering pump, alternator, etc
to save me the hassle of searching for individual parts and putting it all
together. I also gotta find a 7mge ECU and wiring harness.

D. Pull the old 20r out, swap the motor mounts (if necessary), do what I
have to do to make the motor/trans bolt up, and figure out the wiring so
that the truck runs, the dash gauges and lights work, and everything else
works. I read that the 22r and 7mge harnesses are almost identical, but
some of the wires will need to be spliced together to make the dash and
everything else work.

What else am I missing? Thanks again for the help.

this page should be helpful to you if you haven't seen it already.

still need to figure out: water/heater lines, cooling fans (i think you'll need to go electric...but don't quote me on that) air filter/airbox, power steering lines (which you briefly mentioned), and checking for oil pan clearances to the ifs.

this is just what i can come up with off the top of my head. remember, on any project like this, there are always more hurdles than you think up-front. be prepared to take your time and do it correctly, even if that means more slowly.

this is an excerpt from that page...he's doing the 7mgte, but the same factors apply to this paragraph:

"Some of the parts needed for the swap included the Supra radiator. It is a lot larger than the 22R radiator and is needed to prevent the engine from overheating. Also, because the Supra engine is approximately 4" longer than the 22R, I was unable to use the mechanical fan on the water pump. I substituted a 14" thermostatically controlled electric fan sandwiched between the radiator and the intercooler. I have installed a toggle switch override for racing to pull cool air through the intercooler. The motor mounts are stock 22R mated to the engine brackets from a MKII Supra. The oil pan was notched to clear the tie rod and the brake booster was modified to clear the intake. I originally started with a W58 5-speed transmission from an 85 Supra. The W58 transmission was designed for an engine with approximately 150 hp and held up great until meeting it's demise at the drag strip.. Physically, it is the same size as the 22R 5-speed with the only difference being the shifter sits about 3" further back. This necessitated that the trans tunnel be trimmed to clear the new shifter. I made the mistake of using a stock clutch to begin with. It slipped from day one and lasted less than a week. It was promptly returned to Auto Zone and has since been replaced with a Clutchmasters Stage IV racing clutch. The truck now has an R154 5-speed transmission from a 92 Turbo Supra. It is built a lot stronger and will hold much more power. I went with a Spec Stage III clutch this time around. It is a lot smoother and more streetable then the Clutchmaster was."

How was the shifter position on the R154 compared to stock?

idayota

the guy i just quoted said it ended up 5 inches rearward of the stock 2wd pickup shifter.
