LUMBERZACK

one thing I wish I did was reshape the bellhousing opening for the trans tunnel. It would be nice to have more clearance around that area so that it is easier to get a socket and wrench up above the trans to access the bellhousing bolts.

Finally more progress on this build, but I see you're going deeper into it. Don't fall into the pigeon hole of, "well, while I'm here....I might as well..." Then you have a three year Creesida build you never drove. lol Either way nice work, I hate that fucking bump when I had the stock twins. No issue with single lol.

I also started installing some heat shielding on some hoses. I obviously haven't gotten to the extent that I want, but it;s a start and I will continue adding with time. I may get a turbo blanket. Not sure yet. I'm thinking of at least adding some gold reflective tape to the wastegates to help prolong the life of the diaphragm. Feel free to add suggestions.

Leading up to my scheduled drift day, I have a couple things I want to take care of. Most importantly is better securing my battery. Last event I was at, the guy at tech was tugging the fuck out of my battery box and broke one of the strap loops. He said, "Sorry about that...I'll let you drift today, but make sure that's fixed by next time.." Thanks dick. So I bought a billet hold down tray for my Optima and called my good friend Marc the fabricator. He drew up a design and started making a holder. His goal was to make a holder that the battery tray could mount to, that was very solid, but was also removable. Here's what I started with. Autozone battery box. Probably not the best thing every, but it works. Billet tray for Optima batteries. Seems to be nice quality for $60 on Amazon. At this point, Marc and made a square bracket for the tray to attach to out of square tube. He then made a plate to run up and utilize the three threaded inserts for the spare tire bracket. This is how the holder is looking. For the attachment point on the opposite side, we decided to drill a hole and weld a threaded insert so the bracket can be bolted to the car. I scraped away some of the tar and grind away. Marc using his clever trick of using a unibit to drill a hole that will capture a nut and allow you to weld it in place. Flush, now time to weld. Welding on the seam sucked with all of the gasses from the seam sealer, but Marc made it happen. Marc decided to relocate the ground as he used a larger thread bolt than the wimpy bolt I was previously using. I'm super happy with the turn out. I'm going to put that spare tire brace back in, but this this is sturdy as hell. The suspension will move before the battery, so that's a win.

I don't think I've checked the wastegate ports on my STi in the 6 years I've had it installed lol, but I'll keep it in mind.

The way I have it is the only way it will work and is what is required by Tial. Top port is for keeping the wastegate closed, typically controlled with a boost controller, lower port is to open the wastegate to bleed excess exhaust when the charge piping sees a pressure exceeding the wastegate spring pressure. It's not over-engineered, it's what is needed for a properly set up twinscroll system. I'm going to be drifting on Nov. 17 and will be practicing with stock arms and knuckles. I plan on extending the LCA's and modifiying the knuckles later in the season which will give me front camber and more angle, but for now I want to continue drifting one mod at a time so I can understand and feel the difference.

Thanks fellas! Casey, at idle? So you're saying yours idle so quietly you can hardly hear it? lol. The sound difference from twins to single turbo is massive. I'm sure a lot has to do with the fact the twins setup is very restrictive off boost and single is 100% free flowing.

https://flic.kr/p/2bjQGAX Decided to go out and get some audio of the car. It’s not much, but I don’t have a 24/7 film crew like these YouTube faggots, so this is what we get.

HA that's what I'm here for, to remind some of these old folk that a young whipper snapper can get a Cressida running faster than them.

¯\_(ツ)_/¯ Good thing Cressidas are still disposable and I can paint.

Yeah Gibbs, and it doesn't help that I don't have any ceramic coated exhaust parts or hood venting. Luckily the weather is much cooler now, but I'm hoping to heat shield all the vital components near the exhaust. Thanks Casey! I'm stoked on the turn out. I'm really excited to take it sliding and I really hope I get some good coverage to post. The last few events I've gone to, I don't get any pictures or videos, so they just get lost in my memory. lol.

After all of that, the car has been running amazing. The ECU is handling the new single flawlessly. I'm currently running 11.60 wastegate springs and seeing a consistent 1 bar reading from my Defi throughout the rev range on full throttle. AFRs are super healthy 11.2-11.6 WOT. Could be a little rich, but at least my fuel system is adequate for the setup. The thing is much faster than it was with the twins. With that said, I am definitely going to have it dyno'd to compare the difference. I'm also going to be doing some preventative heat shielding on hoses and things around the exhaust. The next drift event is on November 17th and I'm preparing my car for it. So I hope to have some good content to post here in a couple weeks. In the mean time, just look at more pictures. Cars and Coffee again... lol

The last week or so I have been driving the Cressida daily to work and figuring out the little bugs. I have been changing out wastegate springs in attempt to get them to control boost properly. Even with using the lightest spring, although the wastegates would crack open, they were not controlling the boost. I reached out to a friend and after some back and forth, he asked me if I connected a boost reference to the lower port on the wastegate. That's a no from me dog. My theory was that exhaust pressure alone would be what opens the wastegate and controls the boost pressure. My friend was positive that my theory was wrong and sent me the Tial vacuum diagram that showed how to hook up the wastegates. It showed a boost reference line off the chargepipe to the lower port on the wastegate, which provides adequate pressure to push the wastegate diaphragm and overcome the spring pressure of the wastegate. Basically the compressor side controls the wastegate, not the exhaust. I had nothing to lose, so I got lines made and tee'd AN fittings off my chargepipe. With limited shops open on Saturdays, I used the Stainless water port AN fittings from Tial and my friend Marc welded it to the stainless air port plug that had the correct thread pitch. You can see the air port plug on the left in this picture. Marc drilled out the center of the plug and after "Milling" down the threads on the AN fitting, slid the two together. It was fabrication art in its truest form. Found these weld on Vibrant AN fittings at a local off-road shop. Really nice quality and I like the trumpet style milling. Welded

Yes! Gonna be good content to have more active projects. That tow rig you have is rad. Nice pictures.

It really wasn't as bad as I expected. You could definitely fuck it up, but it's pretty easy to follow. I used the TSRM, which is basically idiot proof. This link is the pdf TSRM that covers the W58 and R154: http://www.supras.org.nz/techinfo/TSRM/14_MT.pdf
