2015 BRZ Track Car Adventure (Harrop to K24)

[RedReplicant]

Surprisingly, probably due to the surge tank setup, I was able to pump the fuel tank dry with the normal in tank pump. Car took 12gal of 91 from jugs and wasn't overflowing so I'm fairly confident it'll be fine.

Radiator hose got heat shielded, funnel for bleed ready, etc.



First start happened

Found that the car wasn't charging and the car cut off at 8v indicated in Haltech, with some help from the KSwapped FB group I found that I'd inadvertently swapped relay positions when removing the Harrop kit on my car. Looks like charging is good now




Found a few more things to add to my quickly growing to-do list:
1. Secure the fuel lines in the engine bay so they can't vibrate
2. Oil temp sensor calibration is way off
3. Need to make the throttle body mapping updates Tyler posted on FB (https://i.imgur.com/S3PTOtF.jpg)
4. The out of the box tune is looking for 43.5psi fuel pressure, my surge tank FPR is set to 60psi, need to fix that. I greatly prefer a fuel pressure sensor so I can add a failsafe.

First drive went super well

Few notes:
1. The Sachs Sport Metallic 4 puck that I was worried about feels like a stock clutch, absolutely zero issues and a massive relief.

2. I forgot to plug in the wideband after moving everything to its final location, the car felt like it wasn't going into VTEC but still felt about as quick as my FA20 bolt-on BRZ so I wasn't positive. Plugged in the O2 sensor and now we're getting somewhere, feels pretty good on the base map for what it is but I'm sure a proper tune will be night and day.

3. I left my breathers open since I'm waiting on my catch can stuff to show up and I also overfilled the crankcase by a quart thinking I was going to plumb in my oil cooler before first drive. Yeah, now I have a bit of an oil mist mess to clean up.






Got a decent checklist of little things to get done.

Knocked out some aluminum remote reservoir brackets to bolt down the Rennscot JRZ mounts.




Bought a Vibrant catch can, which ended up being a lot larger than expected. Mounted it to a couple of existing holes on the left strut tower and used some pushlock 10an fittings to connect it to the valve cover.




Currently working through insane oil temp readings, ensuring the cooling system is has a full bleed, and a bit of smoke that I'm not entirely sure of the source of. The catback I bought had a ton of burned oil in it, so that is my hope.

Cooling system was fully bled, I ended up figuring out that someone had wired the Verus Spal fans to the stock plugs and it was just popping the 25a fuses. Ordered two Spal fan relay kits, wacked them to a piece of aluminum, and wired it all up. I hate wiring, I should probably get some harness wrap for it.




Also figured out my smoking issue after resigning myself to pulling the cams and ordering valve stem seals.

When I put the car together I filled it with enough oil to account for the large Setrab cooler, but it ends up that making two AN lines is still on my todo list. I bought a safety wire drilled drain plug, which showed up today so I figured I'd just try draining the extra oil and swapping / wiring the plug.

Surprisingly (to me), no more smoke. I'd always figured a not excessively overfilled car would just push extra oil out the breathers (and into my catch cans), rather than somehow pull it up past the rings. Lesson learned.

Car actually feels pretty sorted and I'm pretty happy with it right now. My todo list is down to:

* Build two 10AN oil cooler lines
* Dyno tune
* Build bell housing cover
* Swagelok the stock fuel hardline to 6AN, make a 6AN line to the fuel rail, and wrap it in Aeroquip fire shield
* Corner weight
* Build a exhaust side heat shield
* Plumb in a flex fuel sensor

Put together two AN lines today out of leftover Aeroquip stuff I had and some Aeroquip StreetLite hose. Still paranoid about the whole thing, I want to figure out how to secure it better too. I might end up moving it to the right side of the car, but there are a few complications in doing that.




Tuner can't get to me until July 5th so I picked up a new set of ID1050x injectors from a friend that works at ID and recrimped my injector harness to USCAR from the Honda plugs. I bought an ethanol content sensor, mount, and KPower flex plug but was shipped the wrong thing, so that'll have to wait.




I set up the dead times that ID specs for 400kpa, chopped the base fuel map by about 70%, and did a little bit of adjusting at idle to get everything back in the right AFR range. I'm not planning on driving it except to the tuner so we should be good.
