For those that are interested here is some good info on trying to convert a shorty straight 7M intake to a long Y-Pipe intake.
http://www.supraforums.com/forum/showthread.php?t=309728

Basically Cressida's and Tubro Supra's have a shorty straight intake like this:

And N/A Supras have a long Y-pipe with a plenum that is equipped with ACIS (Acoustic Control Induction System) and look like this:

I'm still not sure which intake I'm going to use but I'm thinking I will use the Supra Y-intake and plenum with my Cressida Thottle Body.....

I would make that intake longer though and put the AFM toward the grill. I think you might have problem with intake pulses if you put the AFM right there at the end of that pipe, at high RPMS, it wouldnt' make a difference, but at low RPMS, I could see you losing some power.

I'm still trying to identify this strange intake and I started a post over on Supra Forums directly related to it. So I thought I would post a link to that thread. Hopefully the guys over there can figure it out. I've also called a Toyota Parts Guy and he is working on it for me also.

Heres the serial number on the block - anybody got a reference sheet by serial numbers??

7M 0381113

And here are some part numbers off the odd parts.

Thorttle Body
22030-42020

TPS's (both of them have the same numbers)
89452-14050
198500-0241

TRC device (I have no idea whats it really called)
89632-30020

Can anyone look up those numbers in some master toyota parts list???

Hmm, interesting thread over there. You have got a rare find there. Wonder if you can make use of the traction control device. Smile

bolt pattern is the same I am sure. I put a 7MGE TB on a 22RE for a little while. Worked fine.

I got the head back from the machine shop yesterday from Motor #3.

This motor didn't look like it had very many miles so I didn't have a "complete" head job done with grinding the valves and all of that.

What I did have them do is:
* Dis-assemble the head
* Hot tank it to clean it all up
* Remove the broken exhaust stud
* Surface the head (took .012" off to clean it up)
* Install new valve and cam seals
* Re-assemble the head.

That cost $95 so it wasn't too bad. But atleast now I know its all in good working order and nice & clean.

got the engine together yet?

I just had to replace the rings on a motor last week.

From engine running ->pull ->teardown -> replace rings -> rebuild -> install -> drive off = 8 hours. Next time I will try for 7 hours.

Well I worked on the 4runner all weekend long!

Friday night:
I basically got everything removed from the front of the engine bay. (grill, winch, fan, radiator, power steering, alternator, water pump, distrubitor, charcoal canister, coil, afm, etc...)

Saturday morning:
I finished preping Motor #1 to get it pulled out of the 4runner.

Saturday afternoon:
I got motor #1 pulled and set onto a motor crate in the garage. I also got the garage organized so I could transfer everything from motor #1 onto motor #3, which was a BARE short block on a engine stand.

Saturday evening:
I started assembling Motor #3 and I wasted a lot of time trying to adapter that Import motor Y-intake and plenum to use my US model Cressida Throttle Body. In the end I decided it was more work that I wanted to get involved with and just decided to install all the US model cressida intake, plenum and TB onto the new motor #3. Except I did remove the EGR system because the head on the import motor was not set up for the EGR. And as a bonus, I now don't have to worry about my EGR hitting the firewall because it was REALLY close before.

Sunday morning:
I finished assembling motor #3 and got it on the cherry picker.

Sunday Afternoon:
I got motor #3 dropped back into the 4runner. Then I started hooking back up the wiring harness and putting the assesories back onto the new motor while it was in the 4runner. Basically the less you have on the engine, the easier it is to pull and install. Pulling the engine was pretty easy because I removed the water pump. But on the reinstall I accidently already had the water pump installed and I really had to fight it to get it back into the engine bay. But I got it!

Sunday evening:
I worked on getting my 210 York mounted to the 7MGE. That really went pretty fast because I had most of the mounting brackets already made from the first time I installed the motor and mocked up the brackets. but then I got to the point where I needed a belt before I could go any farther and the auto stores where already closed. So that pretty much ended the work for the evening because I need to finalize the York before I start putting the radiator back in the vehicle. Just for the fact that the engine bay is really tight and with teh radiator out, its much easy to mock up the york brackets.

I'm hopping to have it up and running by this next weekends club fun run......

Well heres a picture of my weekend progress.....

Here's a picture of the two OBA brackets I made for the york 210. Nice and simple....

Heres how they look when they are bolted to the York.

And then to the motor.

Front view of everything installed. and its just an optical illusion that makes the belt looks like it hitting touching the water pump pulley. I ended up using a 377K4 belt which fit perfectly!

Bottom view of everything installed. And yes, the york is close to the frame rail but I doubt it will ever touch.

So here it is with all the belts installed on the 7M with the alternator in the factory position, Power steering moved to the driver side of the engine and the york mounted where the power steering was orignally.

And here is how it looks now. I've almost got this Motor #3 completely installed and now with OBA!

Rob - I check out the oil-pump from the old motor and everythign is on the tight side of the factory specs, so I'm just going to clean it up and install it in the new motor. BTW this was a new factory pump when I put it into the first 7M.

I also found out that I ended up spinning #4 rod bearing on Motor #1....

Motor #3 is now completely installed! It fired right up on the first turn of the Key!!! I love it when that happens!!!

I got all the fluid levels topped off, checked the timing and took it for a drive. Feels just like the last motor, so I hope thats a good thing. To me it still feels kinda doggy at highway speeds from what I would expect but the first motor felt the same way.

The last motor had a 195 degree thermostat in it, so for this motor I installed a 180 degree thermostat and so far that seems to have stopped the temperature from constantly changing while driving at freeway speeds so thats another plus.

I also found out that I have a noisy bearing on the pulley side of the alternator which makes the engine sound funny, so I need to get that fixed ASAP....

Plus the OBA even works! Its got a small leak at the pressure switch, but it works!! I've got a few little things to check over before this weekends run, but nothing major. Its mostly just little stuff that I need to tidy up and I need to double check everything to make sure its trail ready.

Great. Hope this one is in better shape than the last.

Let us know how it does on the trail. Last time you said it seemed like it was laking a little.

Don't know about the highway speeds. Could be because you are trying to move a brick throught he air at hight speeds. Never have driven a non-turbo in a truck for more than a few minutes.

What is your exhaust like? Also, advance your timing to about 12-13.
