Irace86.2.0 Build

[shadow_772]

Beautiful interior, I'd been looking for a gauge pod like the cluster pod you have!

[Irace86.2.0]

Another update:

I installed the lower trays and cleaned the garage (it needed it bad).

I got a revised tune from DT with a new set of instructions for logs to perform under variable conditions. I did those and sent them off. I am hoping to get the next revision and set of instructions tomorrow.

I drove to wash the car, yet didn't go into boost as instructed. Even without doing that the car feels really smooth, and I can tell there is a monster under that pedal waiting to come out of its cage, haha.

Finally, I want to give a shoutout to @johan for selling me his kit, helping me with the nuances of the install and just for being a stand up seller and guy. Also, a thanks to @sales@delicioustuning.com for working on my tune and for having a quick turn around time and communication. And to my wife, who is always supportive of my hobbies, even the expensive ones.

SO glad things are going smoothly for you. Can't wait to see more pix of the engine bay too. I'd love to see how you actually routed the piping.

From the radiator, cold coolant leaves the bottom, it travels up coolant hoses until it gets to a pipe that runs on the passenger side of the motor. Cold coolant travels that then enters the pump and is ejected perpendicular to its original flow to the back of the motor along hoses where it diverts to either side of the supercharger manifold. The coolant makes it way to the front of the manifold along pipes before circling via hoses into the heat exchangers. Hot coolant leaves the manifold and travels the same route back to the top of the radiator.

This is a shot of the top cool pipe that has a curve towards the access area behind the headlight. I used the screw on the alternator as a mounting point. You can also see the exit of the pump and the return:




It gets a little messy on the back side, but that is out of view:



The pipes sit close to the runners of the manifold. They emerge or enter medially to the manifold runners and laterally to the alternator and AC compressor. I wrapped the hot pipe in a sheath of hose for insulation:

[Irace86.2.0]

There is a bung on the back of the manifold on the passenger side. I removed that, which required the use of a 3/16 sized Allen wrench. The bung was tapered, so I assumed it was an American pipe thread fitting or National Pipe Thread (NPT), which made sense because a 4.5 hex and a 5.0 hex (metric) wouldn't work.

I found a 1/8 bung to 1/8 NPT brass fitting at the hardware store. I installed the fitting into the manifold with Locktite. I removed the boost connection that was T'ing into the brake boost line and set up the hose to the fitting, and tested the car. I am happy to report that the boost gauge is reading boost finally.

Awwwwwwwww my clutch went boooom! lol

I was data logging, and the clutch went. I only have 63k miles on the car, but I am not gonna lie--I abuse the clutch. I brake with the clutch/engine a lot. I was running the 85mm pulley for like a week then the 95mm pulley. The gears were getting harder to engage, so I thought it might be going, but it seemed to not be slipping, which I have felt/saw rpms fly sky high on boosted cars when the clutch slipped.

Back in the day I had what I thought was a noise consistent with what people were saying was a bad throw out bearing. Some said it needed replacing. Some said the clutch rod or something in the engine bay can get wet/rusty/dry/whatever that makes for the squeakiness. Regardless, the noise came after a hard rain then went away on its own after a week, but nevertheless, I'm sure the throw out bearing is toast.

Most said the stock clutch would be fine at base boost levels, so I was hoping the clutch would last a little longer than this. Looks like I'll be spending more time in the garage lol

It was bound to happen...

I assume you got the verus fork w/TOB?

The fork is on the order list, as is the pivot. I’ll get the TOB locally. I’m not too convinced it is necessary.

If it's never been replaced, you definitely should. Subaru revised the design for a reason. There's even a TSB: http://www.ft86club.com/forums/showthread.php?t=117440

I’m aware. I posted a thread in the engines section about it, and I got a similar link. The TSB said that they essentially increased the heat tolerance of the oil while maintaining the lubrication factor because it is possible the TOB would fail from drivers resting their foot on the pedal. If that was really the case then that oil would never be good for any manual car, so why did it ever exist? Seems more like they put a dot on the old TOB and just replaced the item.

I know I know. Conspiracy theories are wack.

I also heard the stock fork is bad on the TOB, so I’m curious if that is a cause of failure. I may roll the dice. Worst case scenario is I have to replace the TOB in another 63k miles, which for me is like ten years of driving.

[Irace86.2.0]

I removed the transmission today. It took about seven hours. The TOB was toast--literally. The bearing backing was separated from the rest, the bearing was empty of oil, and it was burnt. Seemed like it was burnt plastic.





The clutch, flywheel and pressure plate looked to be in good condition. Nothing was chipped or broken. The clutch plate had some decent thickness remaining. Good enough to use, but I'm upgrading while I'm there of course.





The flywheel will get resurfaced and a new pilot bearing. A new fork and pivot.




The transmission snout wasn't chewed up, as much as, it was worn down. I don't know what a new transmission snout looks like. Maybe it already comes with a step or decreasing diameter, but I feel like this might be worth replacing. At minimum, it needs some cleaning with some high grit sand paper and polishing.

I emailed Exedy last night and got this email this morning

Hi Justin,

Thank you for choosing EXEDY products for your vehicle.

Currently the updated bearing is only available from Subaru or Toyota. The bearing in the kit is the old version. We are working with the bearing manufacture that supplies the updated bearing so that we can supply this bearing in the near future.

If you have any further questions feel free to contact me.

Steve

Today I’ll be buying the snout and MY17 TOB.

[Irace86.2.0]

I received my snout today and swapped it out.







The Verus forged fork may not be as pretty or light as the billet version, but this thing is stout like cast iron solid stout.




The flywheel got resurfaced, and I received the clutch kit too. I have the new (white dot) TOB and some lubricant for the install.

The Motul 300 was on backorder, and I searched all over the town for a supplier, but no one carried it, so I decided to order some AMSOIL over going with the Redline that was in stores. The AMSOIL is also rated 5 for the diff and 3 for the tranny, which seems better than the 4-5 rating on the Motul 300. Yes, the tranny can have 3-4, so that works, but I think the dedicated ratings AMSOIL provides might be better. We will see how it goes. I get that Monday, so I will install the tranny Sunday and fill with fluids Monday then start the clutch break in process.
