4RnrRick is getting a 7M-GE / 7MGE Motor swap

[4RnrRick]

Heres how the exhaust turned out. Ended up being $300 for everything from the collector back and I provided the Cat and the collector. Its all in 2 1/4" exhaust and a 'turbo' muffer was use to keep everythign nice and quiet - I'm just sick and tired of my previous loud exhaust systems.

I choose to run the exhaust under the bellhousing instead of under the oil pan because I still wanted access to the bell housing bolts and the oil pan bolts.



The installed did a really nice job at bracing every point on the exhaust system. I was pretty clear on how I wanted it done and he exeeded my expectation. Also even doing it this was there is no way the driveline can hit the exhust with dual cases even with my low lift.



And here is the crossover. nice and clean.



And he was able to tuck the cat up nice and high above teh 2" lifted Sky's crossmember.



And then down next to the the traction bar (it not quite as close as it looks) and dumping it out right behind the center of the axle. that last Jog in the exhaust is mostly for sound deadening and for getting the exhaust away from the springs.



As far as driving impression so far..... I REALLY like it! Feels torque off the line and this motor likes to REV! The power band just keeps going and going.... Its really nuts! And I still haven't gotten around to even checking the timing yet! The distrubitor is still in the same location I put it when I bolted everything back together.

[BigMike]

Wow, wish we had a nice exhaust guy like that in our town

[lilbuddy]

Very sweet job. Now all you need to do is check the timing and then go take it for a performance run again to compare results. Really good job, you did it really quick too.

[1Bad4Runner]

beautiful exhaust job. Hope it sounds as good as it looks. 

[4RnrRick]

Well I finally found my wiring gremlin! I was getting a 1.3A drain on battery only after I connected the battery and started the engine once.... plus the heater fan would then have power to it after I pulled the key out..... And the other thing that keyed me into a problem was my EFI relay was getting warm to the touch...

Basically when I wired the EFI main relay I just spliced into the main harness where I needed to cut the existing wire and then splice into it. I was getting a weird power feed back though the system that after turned the key for the first time and it would engage the heater relay and then it would send power to the wrong side of the efi relay. It was a PITA to find but I finally did!!!

The other thing I worked on was adjusting the 4cyl tack to read the correct RPM for the 6 cylinder motor. Well that fix was real easyusing this info:

http://www.mindspring.com/~jayk3/toyota/tachmod.htm

But I had one heck of a time trying to figure out what the actual RPM of the motor was! I couldn't figure out how to hook up my dwell/tach meter to the coil to get it to read RPM.... Everytime I hooked it up I was only reading 150-200 RPM. I even borrowed two other meters and they did the same thing. So I finally gave up on that and I was able to wire in the donor car tach from the cressida instrument cluster. but the odd thing about that is that was only showning 500 rpm at idle..... to me it sounded more like 700 ish.... so anyway I then hooked up my 4runner tack and set it accordingly. I would still like to figure out what I was doing wrong so I can compared the actual rpms to the tach as say 3000 rpm.

So I basically spent all yesterday working on those problems.... doesn't feel like I did anything productive!





And here is going to be my last entry on my actual costs. I don't expect to be buying anything else for this motor swap. I've also still have about $200-$300 of more stuff off the motor that can be sold. so that would put my total cost for this motor swap and dual batteries around $1700-$1800.

[UNBREAKABLE]

what did you do for the fuel pump? Are you going to use the existing one in the tank or go with a wilboro?

[4RnrRick]

I'm just using the stock 22RE fuel pump that came in teh 85 4runner......




Well I finally got around to cleaning up and looming the wires.



I also got the computer mounted.



And I was able to wire up most of my accessories. but still need to loom a couple more wires in the driver side kick panel and drive side fender.





So far I have put about 70 miles on this engine. Power is great at lower speeds. Maintaning 65-70 mph on the freeway the throttle is only open 15-20% in 5th gear. Before with the 22RE it would be 80-85% WOT in 4th gear. But over 75mph the engine feels sluggish - Sure thats faster than I should be going but I'm just trying to find all the quirks and bugs in the engine.

One think I did notice when I was timing the engine, I would short the computer and the timing wouldn't change. So I ned to look into that more...

Also the water temp gauge is constantly cycling going up and down. I didn't replace the thermostat, but I think I should with one that is a bit cooler than stock. and on top of that I keep blowing my 25A fuse for my electric fan, so I need to bump that up a size.

Also for some reason my death wobble is now worse than before! So I've got a couple new Irok's coming for the front axle but unfortionately they're out about a month.....

[dirtyskivies]

damn rick, you get done fast!!!  id sure like more ponies, but im too lazy to dive into a motor swap

[crawlerdan]

your my hero rick!

[4RnrRick]

COMPARISON PERFORMANCE TEST RESULTS!

The baseline tests where done right before I pulled the 22RE out of the 4runner 4500 lbs +/- 10 lbs with an empty gas tank, built 22RE, W56, Dual cases, 1/4" thick drivelines, 5.29 gears, 36" Bias ply IROKS at 15 psi.

I have not weighed the 4runner after the swap (I'm expecting it weighs 80 lbs more due to the engine) and I now have a 1/2 tank of gas (another 50 lbs). Also I have two slow leaks in the Iroks probably due to crap in the bead, So the tire pressure is lower than before.

You won't believe some of these numbers.... Also keep in mind that I timed these myself with a the second hand on my watch. So they are not very accurate but the do show a very impressive increase in performance!

Test #1
0-40 MPH on flat ground
22RE - 10.5 seconds average (2 runs)
7MGE - 7.5 seconds averaage (2 runs) {40% increase}

Test #2
0-60 MPH on flat ground
22RE - 23 seconds average (3 runs)
7MGE - 13.5 seconds average (2 runs) {70% increase}

Test #3
Hillside Drive - mild hill close to the house
22RE - Top speed at crest was 48 MPH in 3rd gear
7MGE - Top speed at crest was 57 MPH in 3rd gear {19% increase}

Test #4
Sunset Drive - really steep hill close to the house
22RE - Top speed at crest was 31 MPH in 2nd gear
7MGE - Top speed at crest was 47+ MPH in 3rd gear* {52%+ increase}
* = I had to let off the gas on one corner of this hill because I was going too fast and actually started to power slide on dry pavement!


Also something to note is that my death wobble is worse now after the swap which is probably scuffing some speed off the results with the 7MGE.

[1Bad4Runner]

Sounds like it was a good swap.

[4RnrRick]

And heres some final dimensions.

Ground to the bottom of the front crossmember.
22RE - 25"
7M-GE - 25"

Ground to the bottom of tranny bellhousing.
22RE - 23"
7M-GE - 24"

Ground to the bottom of the oil pan.
22RE - 20 1/2""
7M-GE - 23 1/4"

Ground to the bottom of Sky's Crossmember.
22RE - 19 3/4"
7M-GE - 20 1/2"

Ground to bottom of Transfer Case Parking Brake Mount.
22RE - 22 1/2"
7M-GE - 22 7/8"


Well these dimensions puzzled me at first because there is no way I gained that much clearance under the rig with the same amount of drive train lift as before. Until I remembered I didn't check the air pressure in my tires on the previous measurement... So these dims are much harder to intepret than by first glance. Basically the pan on the 7M doesn't hang down as far as the one on the 22RE and the 7m appears to be mounted on the frame rails higher since these more clearance under the bellhousing.

[BUBBA]

Are you not running a steering stabilizer.That would probably help the wobble.Id say that since the new engine weighs more that's why it's worse.

[4RnrRick]

Are you not running a steering stabilizer.

Because a steering stabilizer is a band aid fix to help it but not cure it!

[crawlerdan]

i had death wobble on my 85, with 39.5 boggers, added a stabilzer, to the draglink, better

[4RnrRick]

Lets not turn this into a Death Wobble post........

If you want to read about my problems with Death Wobble and see the things I've done to try to fix it, read this!

http://www.pirate4x4.com/forum/showthread.php?t=331319

Plus I now have new tires ordered for the front axle which I'm 95% positive that will fix it!

[4RnrRick]

I was able to borrow a nice digital timing light with a built in tach. I adjusted the POT switch I wired into the M- and M+ terminals on theback of the tach to match at 4000 rpm... then when I check it back at idle, it was 400 rpm off! actualy RPM was 750 and the tach said 1150 RPM ARGH..... So thats a big no go. Guess I'm just going to swap a V6 SR5 cluster in there and be done with it! Anybody got one for cheap.....

[crawlerdan]

ill look in my junk yard today

[4RnrRick]

If you guys remember correctly, the 4Runner weighed 4500 lbs +/- 10 lbs with me in the driver seat and a emtpy tank of gas. Well I just weighed the 4runner at the same conditions..... me in the driver seat and an empty tank of gas....Its still 4500 lbs +/- 10 lbs. The only thing that is not installed on the 4runner is that during the conversion was my new OBA and I removed the AC during the conversion. So I would have to say that a 7m swap will only gain you 30 lbs.......


Also for the first tank of gas I was pretty hard on fuel consumption with my new found power! I got 12.7 MPG which is basically right where I was at before with normal driving of the 22RE! So I'm expecting better mileage on the next tank.

     Wow only another 30lb's that is awsome.  Weight was one of the only things really holding me back from doing this swap right now my truck with me in it(180lb's) and a half tank of gas weighs 3680lb's so 30lb's that isn't enough weight to even notice, and if it is I could just mount my battery in the back.

[4RnrRick]

Heck I forgot----- I added another battery under the hood also...... Heck its probably no weight gain considering that!!

[Paul_Elbisser]

So how is your temp? is it hot out in your neck of the woods? A head gasket is a terible thing to waste, keep an eye one it. I put asecond temp gauge on my Tstat output. The housing has a fitting you can unscrew and put an adapter in for a mechanicle gauge. I can watch when the Tstat opens, and it works faster than the stock sending unit. But it is broke now. but it did save me a few times I could tell if I was pushin it a bit to hard earlier than if I had just the stock gauge.

[4RnrRick]

My temp is all over the place! But the engine temps are constantly cycling up and down. like the engine gets warm, the thermostat opens and the temps drop instantly. It does this probably once every 2 minutes or so when the engine is at full operating temp. My assumption is that I have so much cooling that by the time the thermostat opens the coolant in the radiator is pretty cold relative speaking. I think if I put a cooler thermostat in it it should be able to regulate the temps so they are more constant.

Outside temps here have only gotten to about 80-85 degrees so its not that hot yet.


Yesterday, I finally got a compression tester extension so I could do the comp. test on the 7M. See with these Heads, you need one of these extensions because the spark plug hole is impossible to get down into to tighten the tester into.



Results:
145, 145, 145, 140, 142, 145

I don't think I've ever seen a motor that consistant.... and I am actually amazed that this was a junk yard motor with a blown head gasket!

As for the spark plugs, they are running lean to me. So I will have to probably tweak with the mixture using the AFM. These are OEM spec NGK plugs have around 150 miles on them.

[CTENG in KS]

This is just way PIMP, you wanna come over to the east siiiiiiiide and throw one of those in my truck?

[4RnrRick]

Let me thing about that for a second..... Ah, No Thanks......... 

[CTENG in KS]

Damn!
How is that turbo muffler workin for you, quiet enough, I am doing my exhaust this weekend and I want QUIET!

[4RnrRick]

This exhaust system ROCKS for being quiet!

[CTENG in KS]

Is it the standard autozone type super turbo...(i think those are made by dynomax aren't they?)??

[4RnrRick]

The exhaust shop told me that what they where putting on "Tubro muffler", so whats actually on there I don't know....

[CTENG in KS]

OK, I did a little looking and there is a "standard" turbo muffler design they all use...
