Oh...so your ECU just "sees" one bank... interesting. So you could have run a true dual exhaust off that if you wanted to huh.

Yeah, but I dont like the dual exhaust on the v6's, just my opinion. That and I have the gas tank in the way of bringing the right side back any farther.

Yeah, the 22r mounts are to far forward. You dont need to take off the upper control arm mounts like I did if you use ORS's weld on mounts, but I got the yota ones (for the same year as my truck, but a 3.0 instead) and thats how they come.

How much is too far? I just started this swap and I have the motor set in place but the engine bay is pretty gutted out so it looks like there is room at the moment. heh

It has been more than a year since I welded in the new mounts, but just guessing I would say 4-5 inches. Put the fan on your motor and put the radiator in place and see what kind of clearance that you have. You might be able to get away with it if you run an electric fan, but it would also mean that the harness is that much farther away from the firewall and it was a stretch getting the harness into place even after the motor was put farther back like i did.

Ok, I have a ford taurus fan assy I was going to use. When the weather permits(my shop consists of my driveway) Ill hook the radiator and fan assy up and check clearances.

I have two Yota's with blown motor's my 4runner and my pickup the pickup is gutted pretty bad as I have already unbolted all the ifs off for the SAS (which I haven't gotten all the parts for my front axle yet). I really needed to get one of these going again, as it has gotten pretty miserable riding my GS850 back and forth to work.

Thanks for the info.

Looking at Jason's pics in post #1 it looks like a least 3-4 inches. https://www.yotatech.com/50632683-post1.html


I bearly have room for my Taurus fan using the 3VZE motor mounts.

Yeah, mt goat has a point. It would probably have to be one of those super thin aftermarket fans ($$$) for that to work.

I remember reading on here (not this thread, but YT in general) that someone said they would rather do 10 3vz-5vz swaps over 1 22r-5vz swap...
Your swap seemed to go pretty smooth, Minus the one month long down time for surgery...

Nice man !!

Hey Jason, What (if anything) did you change with your fuel pump for this swap? I'm attempting to do the same swap in an 85 and haven't figured out the fuel delivery part yet.

I didnt change anything on the fuel pump side. If your 85 is fuel injected you should be good with the factory fuel pump, just wire it in to the 5vz harness. The only thing I had to do fuel wise was have some custom fuel lines made up at the local hydraulic hose supply place here in okc.

Yeah, my 85 didn't have efi, which is why I'm trying to figure it out.

But I'm confused.. you did a 22r to 5vz swap and didn't have to add an electric fuel pump? Just kept using the carb fuel tank and it all worked out? or was the fuel tank upgraded (switched over) previously?

Jason, Congratulations on some nice fabrication work. I would like to see your truck sometime. I live about an hour south of OKC but I drive all over the state for work.

I did a 22RTE conversion on my 88 but I am thinking about a 3.4 now. After I get done with my Airplane. :-)

Did you mate the 3.4 to and 22RE Tranny? I have a W56 and was hoping it will be compatible.
