So I was thinking to myself, wow Ive got so much room in there


I wonder...


Oh yeah, lots of room, just move the cruise box...


And inlet over there...


Should wake it up quite nicely

I need help

 

where do you keep getting all these M90's and why do you insist on mounting them in such ODD PLACES!
jk.

do it do it do it

 

I keep wondering how the MS4 would behave with one of those or even a hair dryer...

 

LOL love the title man!

 

I was expecting problems coming in this thread, hilarious title. I like the odd positioning, so when is the dyno tune

The LS motors fit right at home in our bays. Maybe one day I'll do the LS-T56 swap.

 

Did you get the twin M90 L98 going ever? Did you run it at a track?

 

The twin car is sitting until I get out of school or the harnesses start moving. Right now Im scraping by and dont have the money to dump into a toy. Everything cheap/free I can do, I have done. Next steps are cage, frame extension, injectors, PCM rough tune and beyond, safety equipment etc

This thread was more of a joke, but I dont see why a M90 couldnt help out a little, esp on a stock 5.3. Its no maggy, but its not something to sneeze at either

Building brackets doesnt cost anything though

 

For this VERY REASON, I am banned from jyardin' trips, no extended time @ Summit, Jegs, eBay, etc.....IT'S ALL MADNESS!!!....

 

This thread has inspired me. *making a new thread right now*

 

Speaking of unsupervised, I bought my 2nd LSx while my wife and daughter were traveling in Europe.

To boot, I've got 3 LSx projects in work now, and still haven't driven the first one.

 

five7kid has "IT" bad too Pocket!!

This is ravenously contagious!!!.....

five7kid needs 1 for every day of the week!!!

......

 

If I had one in every vehicle in the "fleet", that would come close to satisfying that. . .

 

Craigslist is the devil

 

lol, a 5.3 or 6.0?

 

Well sheesh send one my way, I need it

 

ROFLMAO!!!!!...

 

I've got "IT" bad, too! My LS3 Fiero 6 speed isn't running, my '96 Vortec 4.3 into '86 S-10 isn't running, my turboed and 4"-bored LM7 '89 Mustang isn't running, my LQ9 '85 300ZX isn't running, my LQ4 '84 Trans Am isn't running, my '83 C-10 6.2L isn't running. My '85 LTD II is running, but it's stock.

 

2004 5.3L

This one's job is to replace the 5.3L in my 92. I think she's got a bad thrust bearing

I would have bought it anyways, deal was too good to pass up esp for a complete engine. Lets see if I can swap it in the bird before G14

 

Want a great way to eliminate all of those projects? Have a kid.

I have to be discrete in how I label my projects around my wife. My "motor swap" is one project, even though it involves pulling the complete drivetrain out of the IROC, doing a head/cam/intake swap on that 350 before dropping it into the GTA while building a 402 LS3-headed LQ9 stroker, then dropping the stroker LS/T56/9" into the IROC.

Yeah... "it's just one project, honey!"

 

If any guys have troubles with their ladies, get the lady to watch Eric Bana's movie titled "Love the Beast" you can find it on www.streetfire.net. In there, there's a couple of 2 minute takes with Dr. Phil explaining why guys must be allowed to keep doing some stuff with their project car.
That's not the only good stuff in there, but it sure gives backbone to your argument.

 

Atilla--!!!!

You have more " IT " stuff than I have wrenches!!!......
I wish you guys luck with " it "-- Ours is still waiting for a day with some kind of sun for a wash & drive!! Rain every day off so far, & it needs a wash b4 going out in public.
Ther's a group of rat rodders going to the local burger drive-in Friday evening. The owner of the place has a 2nd gen Camaro, 8-71 blown bigblock!!!
( edit )
I wonder how five7kid explained his new garage clutter to Mrs. five7kid!!??!!

 

Can you say, "storage unit"?

 

I don't know how the oiling in those things work, but can you ratote it 90 degrees counter-clockwise?

That'll allow it fit fit a little lower & better & should point the outlet towards the engines intake, reducing the # or turns the intake charge has to take to reach the cylinders.

Where are you finding these 'chargers? Junkyards? Off what engine/what car?

 

Love the title on here. Just wondering you have a junkyard full of m90 supers they giving away for free, or just pulling parts off the other car to just see how it might work? Glad your gonna do a fitment after I said something in the other thread after your build. It was funny now cause you had stated you was leaving it alone....I like to think that maybe me or someone else mighta put an idea in your head or pushed ya to do it if you was already thinkin along those lines.I do enjoy watching your fab skills put to work. Hope your wiring business does take off so you have some extra money to finish the twin m90 L98 project.

 

the oiling is internal & sealled off from everything else on these - the most vile, disgusting smelling oil ever created. never ever change without gloves on and a face mask. i dare you to find something more horrific if you've ever smelled burnt m90 gear charger oil.

and there are a few different versions of these, but most commonly found on the 97+ gtps.

keep us up to date, and i deffinitely think you'd need 2 to make this motor breathe
(new challenge)

 

They can be clocked to any orientation. The units are self contained, so no connection to the engine oiling system. For my twin project one is oriented in the standard "up" with the inlet in the rear and outlet downward level to the ground. The other is clocked 8* for hood clearance

On the stock T-bird they are inverted with the outlet facing up at the hood

So far Ive bought 4 off ebay and am down to 2. When I see one pop up for under $100 I bid on it and sometimes I win. Throw a $40 rebuild kit in there and they're good for another 100,000 miles

The local pull-a-part has L67 (GM FWD 3.8 M90's) every once in a while, often with the blower still on there. Too bad they're the GM case. Much too bulky for me. $20 each

I plan on using the twin car as my senior design project, so it should be progressing in the next few years. Im flat out loving LSx engines, so Id be ecstatic to drop a 6.0L in there

You're right, the old SC oil is about as rank as a port-a-john. After my first rebuild I learned to toss the surgical gloves they put in the kit. They disintegrate and the oil sticks to your hands for about a week. The missus loved that. Heavy dish washing gloves survive better

There were tons of versions to the M90 and eaton keeps getting better with every one. The new GEN V's have teflon coated rotors and have become more efficient than similar OEM turbos. I use the Ford T-bird/mercury units because the case is the most compact of any used in a factory vehicle. Mercedes used some with a much shorter snout, but good luck finding used ones for less than a grand, if you can source them at all

For a performance build, yes the 5.3L would require two and Im sure I could make it fit. M90's are rated for 3.0-5.0L engines. I could overdrive the blower, but the redline would limit how high I could spin the engine. Ill never be over 6,000 with this car so it really wont hit the max like the twin car would

Like i said before, this thread was more of a joke but I plan on fabbing atleast the pass side bracket. I may use it on the street for a while or just stick it in the twin car when it goes LSx

 

It's still to cool.

 

If Pocket does change the oil, he'll probly get kicked outa the neighborhood!!

SMART getting a storage unit!! Got room for Pocket if the neighbors riot over the SC oil change?? I'm sure he'd love keeping company with your " IT " projects!!!

Pocket--
If this turns out to be a project, what kind of HP // torque & overall performance gain would be achievable??

 

I bet he wont go to overbored if he said it is his daily driver, but then again it wouldn't surprise me if he did. I bet it is gonna be crazy stoplight to stoplight with torque, but like he said not so great on the topend with it being just one m90.

 

And so it begins

Quick and dirty blower tray. Front left long so I can cut it off whatever length I need


Rough fitment with everything still on the motor (except dipstick


Not happening


No matter what, the oil fill has to go. Not really a good place for it on the drivers valve cover either, but Ill figure something out


Coils and fill cap removed. It sits quite a bit lower. Promising indeed


Thatll do


Collector will need a pretty severe offset


Wooden plate mocked up, good fitment all around


Tight, but has some room to move away still. Ill require some form of limiter to keep the blower case from smashing into the strut tower. My current rubber mounts just wont cut it

 

We have a winner


Oil fill neck needs to be cut off and welded shut. Coil studs can stay though


Lots of clearance


Now I need to source some more 1/4" plate for the collector flange and main bracket. LSx heads are much easier to deal with than SBC because they have 5 extra M10 bolt holes to attach support brackets to

 

My very highest compliments on getting it this far. Please pop the other 4 coils, and the P/S reservoir, and get at least 1 good pic showing us whether or not twins could ever be possible. TIA!

 

Ive decided the twin car will be a 6.0L or larger LSx once the L98 poops. Ill run the twin setup on that, likely larger than M90's though

Id have to disconnect the master cyl just to fit the blower in that area so a drivers side SC isnt happening yet. Most likely it'll be clocked at an angle like the pass side had to be. The LSx engine is quite a bit wider than the SBC so fitting it under the hood gets tricky

I can take a pic of the other M90 stuck in there if it'd satisfy your curiosity though

 

I didn't realize it went all the way back to the brake master. Longer than I thought. Oh well.

 

Unfortunately it does

 

when I first saw this I thought you were joking! Get it done!!

 

wow, this gets cooler and cooler. Nice build. Just kinda curious, would that size super charger be able to move enough air into a street driven lt1 I wonder? My thinking is I would need 2 to still move enough air at lower boost levels since the compression is kinda high. Just some curious ideas being bounced around.

 

It's not too shabby

http://www.capa.com.au/eaton_m90data.htm

Ported, they flow even more

 

Made some headway

Found a piece of plate and got busy. I actually managed to drill all the holes properly this time. Notice my sophisticated precision instruments: vice grips and a drafting triangle


I bolted the plate to the head then measured from the plate to the middle of the outer most rib on the tensioner to set pulley alignment. Squared the tray to the bracket with the triangle and marked the positions on the tray. I clamped them together and drilled some holes to bolt a piece of angle up front to secure the tray to the main bracket. I then dug up a piece of scrap and tack welded it to the face setting square in all directions


Bolted back in place


Blower back on it, checking hood clearance


About 1/4" at the closest. I may slide the tray upwards some to get this closer to 1/2" minimum


Checking charge pipe fitment. 3" is a go. Not sure I even want to bother attempting to cram 4" in there. 3" to 4" adapters are alot cheaper than one 4" 90* bend and the loss of diameter cant hurt flow THAT bad. Stock the pipe was 2.25", twin car will use 2.5". I just wonder how the 4" MAF will like the extra turbulence right in front of it. May be nothing since itll have its screen and the boost really screws up flow characteristics


Cruise has to move, no getting around that. I hope Ive got enough room for the coils though, it's getting tight


Now to level the blower to the tray and weld the mounting studs on, then build the main bracket to tray brace, then tray to cyl head braces

Not too hard, I do dread having to cut another outlet flange. Cutoff wheel on 1/4" plate steel just takes forever. Forming the collector with sheetmetal and a hammer isnt so bad, it just takes a while

 

How does the 'chargers internal oil circulate? Will it sitting at that angle, cause any oiling problems for the lobes?

 

The blowers can be clocked to any orientation. The front snout is the oil reservoir and the drive gears and constantly submerged. Lobes are dry

About the only thing these blowers cant do is run gas through

 

Well.....Obviously I wasn't referring to the air compression portion of the lobes. Of course you would want oil in the air chamber area. I was just referring to the bearings on the ends of them.

 

The entire front mechanical portion is submerged in that stinky oil. Rear bearings are sealed with some other form of stinky oil separate from the front stuff and gets replaced with the bearings

You really can put these anywhere you want

 

the worst smelling oil i've ever come across. god i hated changing that stuff, especially knowing none of the owners prior to me had touched it in 80K+ miles.

 

Moving right along

Flange cut, gawd what a pain


Outlet tube tacked in place


A little tight, but passible


Right into the #4 primary


Back off, tacks broken and the tube pushed all the way down


Slightly better clearance


That'll do


Beginning the shape


Almost done

 

Ground the welds down to look for obvious holes. I found several
Ugh


Water test looking for leaks, already patched one more, think Im good to go now


All for today

 

nice work Jon, seems to be coming together nicely. wish i had a welder...

~Steven

 

you realize you are going to have to make me one right?

 

Its not too difficult, sure

 

i dont have the mad fab skills that you have lol
