I have NEVER seen a Build thread go this hard in only 24 hours! Nicely done, and thanks for sharing it all!
Loving all the pics and explanations of what you're doing and why - folks read threads like this and get knowledge and inspiration for their own builds. Seeing awesome cars in a ton of pieces, getting worked out, getting past things that didn't work out, and working through a builder's thought process REALLY helps the guys that are trying to decide what they want to do and how to do it. It also helps keep all of us motivated through all the tough times when things don't work out! There is a finish line!

So thank you, sincerely, for stopping by and sharing all of this! Really curious to see how that 8085 does!

Can use button heads for more clearance

I didn’t even think/know about the button heads when I did mine would have saved me from ruining two of the bolts. Dam. Great idea

Now this is a build! Wow.

Thanks!!

amazing amount of work!

Looking forward to more.

thank you!!!

I’ve wanted to make this thread for years now but kept flaking because I didn’t think the progress was fast enough. Now that I can see the light at the end of the tunnel I wanted to go ahead and get it out there. Thanks. I know what you mean. It’s hard to keep the motivation and I know that back 10x years ago when I got on this forum the build threads were inspiring. Now with everything on social media it’s harder to keep everything in one place. These forums are very convenient and offer a ton knowledge to people starting out.

Full 5 inch exhaust…

I went with a full 5” exhaust for two reasons.
1. A fellow Supra owner that I follow on IG (think he has the current Supra 1/2mile MPH record) is running the same turbo and says he cant boost over 30ish lbs of boost running a 5” dP to a 4” exhaust.

2. I have a theory that less back pressure you have after the turbo turbine the faster it can spool and some people have claimed the 8085 can be a little more laggy than what they were expecting.

I took that logic and ran with it and made a 5” exhaust. Currently it has three “mufflers” installed on it but being that they are “race” mufflers and do not offer a lot of packing I don’t know how much they will reduce the sound. Now if this thing turns out to be obnoxiously loud i am considering putting a 5” diesel truck muffler up under there to quiet it down

I went with 5” oval pipe for the mid pipe section. It goes down to 3.5” tall and like 5.75 thick.

Like with the IC piping I just tape everything together real tight before committing to tacking it all up. Started with the Down pipe. Kinda hard to snake 5” pipe around two waste gates but we made it happen.

Next one the mid pipe and axle back sections.

Happy with that. Let’s tack everything together…

Welded.

not my best weld but it should work.

The dam thing shrunk like 0.5” in length from the welding. May need to cut it and add a 1” section to lengthen its right now I’m concerned it may melt the bumper.

Amazing build! When you think you've seen it all with supra builds, a build thread like this comes along! I've never seen the catch can mounted at the back of the car like, great idea! Keep the pictures coming!

 

[TurboTurtle]

Geez, posts like these make me believe SF can have a flourishing future again. As Dave stated, keep the updates coming brother!

all catch cans should be positioned there..

Back out comes the motor.

When I got my head done, the machine shop mentioned that they did not need to clearance the head around the cam lobe area for the upgraded cams (BCstage 3+) because there was no binding that was occurring. I was cool with it and went on with my life. About a year back I was watching Headgames Motorworks YouTube channel and they had a video talking about high lift cams and how the VVTI head casting requiring clearancing. He claimed that even if the cam does not bind up, there may still be a problem with oil starvation. The came lobe could be getting so close the head casting that it actually wipes the cam lobe clean of oil and when it hits the bucket it hits in a dry-ish condition and over time that can murk ur buckets.

So in usual fashion I can’t leave anything alone I pulled the valve cover and start turning the motor and found a few cam lobes that were coming pretty close to the casting.

Yeah not too comfortable with that…

So….

Sent the head off to Headgames for cam clearancing, recheck the valve job, and added in a pocket port. During this time between machine shops my turbo and power goals changed a lot so Dave got me right with the GSC 5066 conical valve spring kit good for 1500hp. About a month later I had the cylinder head back.

Around the same time I was trying to figure out what to do about the stock VVTI cam gear. I tried painting it gold to match the BC cam gear. didn’t like it, not the right gold, stripped the paint off.

Was thinking about getting the Drift motion VVtI cam gear cover which looks sick. But decided against it.

I found the pic online with a head that had an HKS vvti cover. Looked pretty clean.

Went with that.

Head back on.

motor back in.

I wish I could but I can’t take all the credit. For a long time serious drag cars will put a “puke tank” in there trunk with a pipe coming out their window. And those are just large catch cans. I kinda stole it from them.

Geez, posts like these make me believe SF can have a flourishing future again. As Dave stated, keep the updates coming brother!

I learned a lot from this forum from way back in the day tryin to give back a bit.
Thanks hopefully the catch can works like I hope. There is a possibility that the line the runs under the car pools with the oil instead of the can and then it could clog up. And id have to drain the line often. We’ll see.

Agree with these guys. I love the way you work, posting finished products and months of work in just a few sittings. Grabs everyone's interest and does not let go.

Incredible work. Just Incredible. Did I say Incredible?

This is AWESOME! Love this build and thread. So good to see the thought process, the plan and the execution all within one or two posts. So keen to see this progress.

 

[TurboTurtle]

The OP is an example of when fabrication talent meets intelligence. At each step of modification, I can see the OP asking himself practical questions and then providing justification for the actual execution of the decision.

This is also a great reference on why it cost so much to pay to have a car built.

The methodology used is a mirror image of top tier builders such as @Patrick94TT

 

[Steve Theodore]

This build thread f#(ks! And, of course I mean that in the MOST complimentary way possible!

 

[SelfishMotives]

This is fantastic! Everything was thought out, intentional, and done with function in mind. Great job. This is going to be a monster! Can't wait for more!

 

[viveenwillem]

You are a genius.

 

[MACh4]

I'm new to the supra game and I love build posts like this. I definitely get to learn more and more about these sweet rides. I checked out that supra back in 7/19. LOL. I definitely wouldn't have done it justice like you have given it. It had some things going on with it that seemed kind of sus so I passed. I was looking for a factory TT supra too so I decided to skip this one. But kudos to you and this amazing build!!

 

[Zumtizzle]

Man this build thread makes me want to wrench again. Nick this is amazing. Keep goin!

This is something I have a Ph.D in, having four motors built by my builder/tuner (three cars), SP Engineering over the years. The first build occurred in 1998 and the fourth is in process, hopefully to be done in the near future.

Indeed this is expensive with a capital "E" but, having worked 60-hour weeks for the majority of my 37 years of public service and, now, nearing 75, I had/have no desire to be an expert DIYer like @TTNickSoCal even if I had the skill, knowledge and abilities which I assuredly do not.

Thanks for all the kind words! It’s really cool hearing your thoughts on the build.

We are pretty much at the present day of this build. A lot of the bigger projects are hopefully finished and it’s time to start wrapping up the loose ends. Kind of boring stuff to come. Last weekend I sanded and coated the turbine of the turbo using rattle can ceramic paint.

Wanted to go the Cerakote route but guy wanted to charge me $150 just for the housing. Trying out this instead

After painting I baked the housing in the oven at (while the wife was sleeping Haha) Hopefully it holds up.

I’m planning on running the -20an coolant lines from my radiator to the engine. I wanted a new radiator but in an effort to not spend the cash I worked with the Misimoto radiator I already had. I needed to weld on the -20an bungs to the radiator.

I will tell you that these welds fought me the whole time. It was a battle in fusing these two together. Not my best looking welds. Passed pressure test.

I also will be running the Prospeed dual Spal fan set up, I picked it up from induction motorsports.

So after I welded, shaved the emblem off, pressure tested and spent some time straightening fins on the radiator. I painted everything flat black.

installed everything and now I am seeing a hint
light at the end of the tunnel. really happy how things are turning out.
