Rusty's 7M-GTE Build Thread

[Peepz240sx]

damn rusty so much work. must feel good huh?

[kmfdmk]

Yeah, but my mileage really blows. I'd say I just dropped 30% of my fuel economy. I might turn the boost down to get good economy, and then turn it up only when playing around.

[kmfdmk]

Ducted my Oil Cooler, Radiator, and Intercooler today... only took about 12 hours, and $50 bucks in parts/tools (I already had tin snips).

24"x36" sheet of galvanized duct sheeting - $10
2x 3/4" x 1/2" x 36" Aluminum Angle - $10
Gorilla Tape (short roll) - $5
Hand Bender/Edger (Handheld Sheeting Break) - $11
2x 65mm x 6mm Bolts - $3
5x 3/8 Nuts (used as spacers) - $2
1/2" x 3/4" Foam WeatherStripping - $10 (good stuff!)
I already had:

A Drill Bit w/ Hex Head (Yes I fucking HAND DRILLED this shit...)
Leatherman (Indispensable!!)
Titanium Nitride Fiskars Scissors... Got them @ JoAnn's for like half off... Same ones are normally like $20+ @ Home Depot
Tin Snips
Sharpie Marker
Tape Measure

YOU SHOULD GET GLOVES... The factory edges on the sheeting are RAZOR FUCKING SHARP. I'm not fooling, I BARELY grazed the edge of the sheeting setting the scissors down and sliced the FUCK out of my middle finger. The only thing that stopped it going deeper was my fingernail. >.< Now I'll have *another* mis-aligned fingerprint.


So I'll let the pictures explain themselves.

This was an exercise in thinking ahead, creative thinking, patience, stamina, and how little I could eat, how much I could shake, and how muggy I could be... It was miserable hot today...

As Usual you can view my Gallery of my Engine Build here... so you can view HUGE size pictures if you need to.

Supplies Laid out... I bought a lot more shit than I needed (I'll take the rivets, the garage weather stripping and a few other things back.


How I was initially sliding my template into position.


Passenger side of the Oil Cooler Duct Template Complete


Closeup of Clearance, about 3/16" or 4mm+/-


Tracing out the Template onto the Sheeting




Tracing Completed - NOTE. I X'd out the areas of metal to discard. Makes it easier when you've got all these lines.




Cut Finger - Wear Gloves, even cheap ass Brown Jersey Gloves... SHARP SHARP EDGES. BTW... in about 2 hours of use, I aged these scissors about 50% of their life expectancy. They still cut OK, but aren't razor sharp like they were. But who cuts sheet metal with scissors anyways...:ugh:


All Cut Out!!


Holes Made, and Seams Snipped


When Doing LONG bends like this, where you can't use the Hand Bender (the Black Rectangular thing my left hand is on), You can cheat and do it like this.


Mocked together




The GAPING hole on the passenger side of my radiator


Passenger side of the Oil Cooler Duct Mocked in place


Top view of the amount of clearance between the Ducting and the front of the radiator.


Side View of the clearance, gives a better idea. < 1/4"


The Gaps at the bottom and drivers side of my radiator


Note how some edges have 45* cuts, and some are radius'd. This makes it easier when folding them together to get them to line up, easier to fenagle into position, and the radius edges keep you from cutting the shit out of your hands.


Damn Holes didn't line up... Used the Leatherman to nibble away at the holes edges and enlarge it.






Drivers Side Oil Cooler Ducting in place. Look closely and you can see that its' top edge IS folded, however the top edge of the passenger side HAS NOT been folded.. YET. I actually folded and crimped the passenger side top plate OVER the drivers side top plate.


You can see it crimped here.


SO.. I decided to go all out and be crazy (because I didn't stop for food, and barely to drink).... and box in the radiator and IC.


Looking down from above on the back side of IC.


Template and Cut Out


All Put Together. There are two pieces, a front piece (No Pictures of it cut out by itself...)






Gorilla Tape around IC. Too tight fitting for Foam, Foam on Radiator Side though.


Drivers Side

looks good man! I love the fact the you hand drilled. I would have gone to harbor fright and got a power drill and then returned it after I was done.

Thought that I would update the thread with some of the more recent goodies.

A few months back I installed a Canton Racing 90 Degree Rotating Remote Oil Filter Adapter Part Number: CTR-22-595 Which cost like $65.95

This lets me run my lines PARALLEL to the block, instead of perpendicular and pretty much pointed straight at the f'ing turbo outlet/charge pipe.

Very quality item, made ENTIRELY from billet aluminum, with a HUGE 3/4" steel banjo bolt inside and two O-Rings (which are a common size, I checked and the spares in my O-Ring kit fit), so it's definitely rebuildable.



I just purchased an oil cooler upgrade. Old one was a B&M 70273 11x5.5x1.5" 24 Row Bar & Plate Oil Cooler rated for 15,000 BTU. I think the reason I had oil temp creep (when @ 65mph cruise in 5th) is because I have a 9 quart oiling system after addition of lines, filters, thermostat, and cooler. And I think that the 70273 was just not large enough to dissipate the heat soak from more than 2 gallons of hot oil.
OLD


New one is a B&M 70274 11x11x1.5" 48 Row Bar & Plate Oil Cooler, rated for 29,200 BTU Hopefully this gets the job done. NO it's NOT overkill. And even if it is, that's what an OIL THERMOSTAT is for.

NEW


On the road update. Sustained 75 - 80 MPH, 3400rpm, 8qts 10w-30 full synthetic, ambient temps 89* F, Intake Air temps 94* F.

Results:

Water 203* F
Oil. 218* F
Oil Press. 38 psi

11" x 11" x 1.5" oil cooler does the job. At cruise no matter how abusive, boosting hard over and over, oil does NOT go past 220* F. 55mph cruise sees a 210* F oil temp (2500 RPM), and 65 MPH cruise sees a 215* F oil temp (2900 RPM).

Pretty damn good to see oil temps at 55mph only about 6* warmer than water temps!! Worth the hassle and the $90 bucks.

The most badass part: I measure oil temps off the line that comes straight from the pump. So that means the temp of the oil is even lower after the cooler before entering the engine!!!


I also recently switched out from my 3" aluminum radiator for a stock MKII Supra radiator, with a 2 speed Ford Taurus fan, and an automatic controller on low speed with a switch to manually control low speed/high speed. Awesome setup. Took me about half an hour to figure out how to do the wiring.

nice man! so long as people run a T-stat bigger is better! until weight plays a factor... where are you mounting that big boy? same place? let me see a pic!
