A little different build...2JZ Supra street/strip Made a build thread for another forum and figure you all might enjoy the pictures as well.
Shortly after my brother started work on a 2JZ FD RX7, I decided to pick up a MKIV Supra. Always wanted one as a fun street car so I drove 25 hours nonstop to get this car from it’s douchebag owner. Long story short, he said the car was complete minus the motor/trany/seats. That was not the case at all.
Anyways, picked up the car and a motor/trans. One of the first things I did was set the motor and trans in the car and start fabing mounts. Decided to use 4130 and solid mount the motor. Transmission is poly mounted.
Driver side:
Passenger side:
Sheet metal intake came next. Huge thanks to my brother for all the time he spent perfecting it to flow correctly in cfd and for letting me pull dimensions off his head flange.
Head flange after 15 hrs on the cnc. Started out as a 1.5" thick chunk of 6061.
Backside of the head flange showing the taper where it meets the head.
cnc'ed plenum flange with radius cut:
Steps cnc cut in the back side for the runner to sit in:
Runners welded to both flanges:
cnc tb flange set up for a Q45 tb:
Final product sitting on the motor after roughly 9 hours of welding. Still needed to add fuel rail mounts, iac flange, and tb cable tab at that point:
Decided to powdercoat the intake black.
While working on the intake I cnc'ed a flange for the exhaust manifold out of stainless. Again big thanks to my brother for letting me use his flange as a model to pull dimensions off of.
12 hrs on the cnc:
one of the 3 to 1's:
After trying to mock up the turbo placement I realized the above configuration didn’t leave me much room for running tubes in tight spot.
The start to the new 3 to 1's. I didn't think about taking a picture after adding the third tube:
Some pictures during the turbo manifold fab. All three are the first pass around the tubes. Ran two passes around each joint:
Header almost done:
With the turbo bolted on:
Cool picture of welding...
Next on the list was an anti surge delete that was turned down out of a piece of solid 6" round stock. It's press fit but I will probably add a set screw to ensure it stays in place. I decided to leave a little lip on the outside to pry on in case I ever wanted to remove it.
Solid diff ear mounts my pop made for me:
Installed in the diff housing:
He also made my rear weld in solid diff mounts:
All welded up:
Subframe cleaned up and painted:
Other bushings my pop had made me for the subframe:
When it came to the fuel pumps I decided to go with dual 255 HP pumps:
Picked up a intercooler core and fab’ed the end tanks to work with the chosen mounting location.
Intercooler pipes almost done. Needed to run a bead on the ends of one pipe and weld the bov flange after I make it.
Powdercoated some more parts for the car:

Made a diff cover to get rid of the weak stock one that would have most likely snapped in half.
Diff cover installed and diff cleaned up:
Down pipe we built for the car.
Motor back in the car for what I thought was the final time.
Tight clearances? Both wastegate dump tubes literally have 1/16" of clearance to other tubes.
Modified the oem waterneck to have a fill/rad cap and cut it off so I can feed the rad on the pass side and not driver side for shorter/cleaner rad lines. Bead blasted and coated it black.
Starting to figure out the hacked engine wiring harness. What a mess.
Laid out so they could be covered.
Dual fuel pumps wired up.
Crappy phone picture but the car was all together and running.
After running it for a short period of time, it decided it did not like the defect clutch disk and slung parts of it out. Took out the trans bellhousing and two of the engine mount bolts off the block. Needless to say the car needed/needs a new bellhousing and new engine block. I have collected most the parts to fix it but am still looking for a engine block. Hopefully we will have it driving shortly. After it is tuned hopefully we can set up a photo shoot for the completed car.
Big thanks to Titan Motorsports (more specifically Nero, Bottle, and Darin) for working with us and providing the prices they did for parts we needed.

Finally getting some time to get back to this car. Since the clutch destroyed the trans case and engine block, we decided to build the bottom end of the motor while it was apart.
Decided on Carrillo HD rods w/ CARR bolts. Did not really want the CARR bolts but that is what Bottle@Titan had in stock and hooked us up with. Also chose to run Titan/JE Coated pistons.
No one local had a torque plate for boring and honing the motor so we had to cnc our own.

Thanks for the compliments guys.
We'll have some pictures of the car once it is running and able to move again. It is more a street car that can be taken to the track every now and then. Just wanted to eliminate most of the weak links and allow for room to expand later with a lot of the parts.

Yes sir, it is in a few places!
Yeah, that was not the least bit of fun. Eventually want to wire tuck the entire bay and use deutsch connectors. Just want to get it running well and tuned for now though.
I doubt it will ever go on a dyno. It is mainly a fun street car to play with but it will be on the track some just to see what it will do. Need to replace the driveshaft before it gets sticky tires though. That's the only weak link left in the drivetrain.
