A while back I hacked up the stock FRS shifter assembly but needed someone to weld it together. I don't do aluminum. Since I'm back in the FRS for daily driver I'd like to see if I can reduce the shifter knob buzz. So I dropped it by a local welder and an hour or two later I picked up the part.

I was hoping to put some time into swapping the shifter setup over the weekend, but the WRX needed a/c attention. I bolted all the lines together and hoped it would hold a vacuum. Much to my surprise it did. So I ran in town to grab some r134a and see if I can finally do a/c work correctly. We got a/c now and it's ICE COLD. So now the CEL is fixed. A/c is fixed. Front bumper is painted. It was another little win which I needed. Still need to paint the wheels and order up a single DIN radio kit. Gotta decide if I wanna use as a daily or just sell it and use the money elsewhere.

Save the Subaru for your kid. Not sure how far away from needing it they are, but its another headache off of your plate to have that sorted and ready.

Made some big moves over the weekend. The Expedition was sold on Friday and Saturday the WRX was sold. The Expedition had a monthly payment and was just sitting for the most part due to high fuel consumption so that's nice. The WRX has basically been sitting with no payment, but the chunk of cash will be useful for other stuff. I've got another SUV for a spare vehicle lined out, but don't want to jinx it so I'll hold off until the deal is officially in motion. I mean it already is in motion but you never know. It's a neat one.

Bye bye Subaru.

Been a month since the last update. New Pilot Sport 4s were installed right before I attended another autocross on the 18th. Overall I managed 11th in RAW time which I felt was reasonable considering my tires are still only 300tw. I was surprised at how much the car wanted to understeer however. Really struggled with that, but could have just been this course or my lack of skill. Either way fun was had and that's all that matters.

Anyway, I've been contemplating whether I still want to build the hopped up k24 or just keep things simple with a stock block. I mean if this one fails I can just swap a couple parts to another cheap used engine and off I go. Super easy and mostly stress free. However I still have the parts ready to assemble minus machining the block. And yet I have been enjoying the lack of tinkering. I know that as soon as I stick all this stuff together there will be tuning, head scratching, a bit of worry, break in procedure, etc. On the other hand I don't want to deal with shipping these parts all over the place and hassling with selling them. It's a pain. A real quagmire if you will.

I also realized that the k24a8 block I have doesn't have oil squirters like the k24a2. Some say don't worry about it if using forged pistons but I'm using hypereutectic pistons which I believe is a fancy cast variety. I may just chase down another k24a2 that needs a refresh for cheap and send the k24a8 down the road to someone else.

 

Almost forgot! Me and a buddy signed up to go to Lake Garnett Grand Prix Revival in Garnett Kansas this weekend. It's an old road turned race track from 50-70s that circles the lake. Many of the greats of the era have turned laps there which is pretty neat. They have a car show, autocross, charity rides, and a mild track excursion/vintage race. We are limited to 100mph on track as it's more of a spirited parade session, but it sounded like fun to try some different stuff for a change. Really excited to see how it all shakes out.

I want to thank you for this thread.  After the valve spring recall killed my engine 18 months ago and Toyota telling me to pound sand, my FRS is finally moving under it's own power again with a K-Power swap.  I got stuck in "analysis paralysis" when considering what to replace the FA20 with (LS, LFX, K24, another FA20) but seeing the quality of this kit made me finally decide to pull the trigger.  I've only driven it about 15 miles since the swap (my exhaust just got delivered today and it was too loud to drive over 4000 RPM with just the header) but so far it's awesome!  This is how the car should have come from the factory.  I've still got some things to do (rerouting and securing some hoses/wires/ac lines, new battery hold down, putting the interior back together) but I'm looking forward to driving this a lot more.  Thanks for all of the tips and suggestions, especially adding the extra coolant line from the coolant neck to the thermostat housing.  One thing I'm not sure you kept from the FA20 was the coolant bleed valve on the heater inlet line. I added it back in and getting all of the air out of the system was really easy, at least I think I got all of the air out.

I had some issues with K-Power promising "just two more weeks before it ships" a few times, and there were parts missing when I finally got my kit, but they shipped the missing parts out immediately so I ended up getting them before I needed them.  My impression is that they're a small company that was a little overwhelmed by the success of their kits and I hope they can stay on top of things.  

Anyways, if anyone else is thinking about the kit, it's definitely worth it.

Cool to have another one!

Did you experience the transmission rubbing on the tunnel problems as well?

Glad you were able to pull the trigger and also that you agree it's well worth it. I think I'm out of the honeymoon phase with the swap, but honestly that's not a bad thing. It's become so normalized now I keep forgetting what I really have in my possession. As mentioned earlier I hazard the thought of messing with a built motor now just because it works so well as is.

I had seen so many people on the ft86club.com thread warning about transmission clearance issues that I overdid the clearance there so I don't have any rubbing.  My valve cover does touch the hood reinforcement, so I will be cutting clearance in that.

I don't have a bunch of pics, in fact very few from the Lake Garnett Grand Prix Revival, but it was an awesome event and weekend. I think I will be going back again next year if the life schedule allows.

We optioned to go to the Friday dinner to get registration out of the way early and see what we were getting ourselves into. Good sized crowd, good BBQ, and quite a bit of cool swag was handed out.

The autocross on Saturday was located on a fairly small chunk of asphalt but they set up a really fun course with two loops to make up for it. I had to stay in first gear hitting the rev limiter for just a smidge of time before braking and only into 2nd to go through the finish. Very tight and if not for my ability to rev to 8500 I would have had some difficulty with it. Anyway I managed FTD and won the under 3 liter class. My buddy brought his 19 ZL1 and would have taken FTD if not for one cone. As always it's a fun back and forth between us. The rest of the competition wasn't near as close in time, with a few seconds between us and the next place.

Right after we wrapped up autocross we headed to the downtown square area for the car show and charity rides. Both of us signed up to provide the charity rides which then gave us a chance to turn some low speed laps around the "race track". It was fun chatting with kids and adults alike on the rides. This may have been my favorite part of the event which is odd because I'm not really the best with interactions with strangers. Socially I'm kind of a dunce.

Sunday we had the "track day" portion of the event. We were scheduled for two 20 minute sessions that were speed limited to 100 mph. After doing the charity rides limited to 45 mph I was expecting the day to be pretty low key and just a chance to have fun. We set up near the fence line to watch the groups while waiting for our session. I was surprised after our first session at how much fun it was. By the second session we were cooking pretty good everywhere but of course the straights. Going off course here in most areas would really suck so you have to kinda run at 80 percent. It was still a hoot though. Passing was a bit sketch. A c6 pointed me by going about 80 mph but dropped his rear right off and almost put us both into a bad spot. Luckily he caught it and I backed off throttle quick enough. Whew! I'll see if I can manage to flip the image from the GoPro since it didn't automatically do it like usual. Kinda weird but whatever.

The car never missed a beat. The drive there and back was like any normal commute. Power wise it felt great on track but I'd be lying if I didn't want just a little more juice to chase down the more powerful cars coming out of the corners. It was WAY better on track even with the 300tw Pilot Sports than the FA20 ever was. That is what I was most stoked about.

I can't wait to get it out at some local tracks again next year as well as try some new events or locations that we haven't been to before. The new Ozark International Raceway is on the short list as well as Eagle's Canyon. Muskogee OK has a really nice sized pad for autocross to check out and it's fairly close. Maybe even a Pro Solo if we can squeeze it in. Lots to do to mix it up a bit.

I'll close this up with a Kansas sunrise.

There were a few photos uploaded to the Lake Garnett page so I figured why not post them here. I still haven't messed with the Gopro footage, probably never will since I keep forgetting about it.

 

 

Almost forgot, I have had to unbolt my OEM audio sub enclosure each time I want to adjust the damper settings. I found some adjustment extenders that Tein sells and sure enough they are perfect. This should save me some hassle before autocross or track now. All clicks can be done right before and after the event for max performance and then back to plush daily status.

Peek a boo.

Very nice! I didn't go with the extenders for my FA 500s as I was told by the company I bought them from that they break often. I may have asked you earlier in the thread, how do you like the OEM Audio+ setup? 

I have the front six speakers for the '23 BRZ now (they replace both dash speakers vs just the tweeters), but the sub/amps got pushed to December. The stock 22+ stereo is a noticeable improvement over the first gen, so I'm excited to see what the full OEM Audio+ setup will sound like. Waiting until the sub/amps get here to do everything at once.

Hoping to have the suspension and wheels on the car in the next few weeks, catback is currently on a month-long back order from the manufacturer.

In reply to z31maniac :

Hopefully I don't have too much issue with the extenders, but in case one breaks I have a spare since they only are sold in pairs anyway. It doesn't give as much of the "click" feel so turning it requires a little more effort to ensure you aren't jumping a couple clicks per turn.

As for the OEM Audio setup I'm a huge fan. I only have the sub/amp as of right now but may order the front speakers as an upgrade at some point. The tuning they do is a massive improvement even with the stock front speakers, and the sub helps fill out the sound. I was a bit worried it would be too much for me bass wise, but it's perfect. The more I crank up the volume the more I realize how well it's set up. I think you'll be pleased with the outcome.

Glad you snatched up the second gen. I'm still kinda on the fence about whether I should have just got one instead of K swapping to be honest. Mainly because of the amount of money I've spent, but then I go for a drive and forget all about that.

I considered picking up another 1st gen and swapping it. But realized after doing my S52 E30 swap years ago, I knew I'd get in to scope creep, spend twice as much as I budgeted for and take 3x as long.

The new engine is pretty strong. So much more midrange than the FA20. Can't wait to see what they will do with a header and E85, since stock they are putting down ~210whp where as the first gen was putting down ~165whp.

Definitely way underrated from the factory.

Lots of little stuff going on here. Recently it was brought to our attention that there is a revision to the Kpower 86 kit. It adds a fuel pump relay which primes for 5 seconds on startup. Currently it gets power as soon as ignition is turned on. Most of the time this isn't an issue but if you have to spend some time in the Haltech software tinkering for a minute your battery is at risk of dying. It's happened a few times before so I reached out to Kpower to see if they'd ship me the new setup. I ended up paying $40 for a relay and some wires but should be plug and play with my current connector.

Nope.

Turns out one of the wires they used isn't connected through the Kpower adapter board. I and a fellow swapper spent time checking continuity between all sources to find the odd disconnect at the board. From what we have been able to gather so far is there have been roughly 3 different boards released, and I have V1 being an early adopter of the kit. He has v2. Still waiting to hear back from them as to what the fix will be, but the other swapper just soldered a jumper wire at the board for now. Hopefully I won't  have to mess with that. I suck at soldering.

Onward we go.

During the holiday break I was basically stuck at home twiddling thumbs. I did a lot of stuff over that time but failed to take some photos so I'll update a bit more soon.

So I FINALLY spent time making space for the pivot pins to lock into the shortened shifter carrier. It took a chisel and 5 pound sledge to the trans tunnel bracket but they went in. Also had to kinda lift the front of the engine a bit and tilt the trans. It was a bit of trial and error finding the right spot but I think I got the hang of the movements needed to get it all together. I had planned to wait to do this until I pulled the engine and trans for some future work but figured it could be done in a couple hours.

I failed to take pics of what it looks like from underneath but the carrier bolts/clips back in place just like stock. Unfortunately the Kpower shifter linkage was just a bit too short to work with the setup. Because the carrier puts the shifter back up inside the cabin higher there's about a 1/2" or more needed to get a good neutral position. I kinda figured this would be required so I started cutting up the stock linkage. It took WAY longer than I anticipated to get all the length and angles right. A lot of that had to do with fitting the carrier and linkage just to test and then pull back apart 30 times. Also the stock shifter had the locating pin things opposing eachother but now that it's way shorter the best path forward was to keep them facing the same direction. This wasted a lot of my time but I really didn't want to get it all finished and have a crappy shifter feel.

Stock.

Stock no longer.

I had to shave one side a little for clearance but after getting it all back together I'm happy to report it all works. In fact the shifter feels better, less notchy, and so much smoother. It feels like it did stock. Which is what I wanted.

I was a bit disappointed that the vibration reduction wasn't has great as I had hoped as there is still some mainly at the firewall. The main change in vibration has been in the 3-4k range when climbing a grade or when that Vtec kicks in Yo! Not as much buzz of the reverse lockout, just a hair at certain RPM and very faint. Highway buzz at 75-80 mph in the shifter is gone. Now the shifter doesn't move under braking like it did before since it's no longer divorced from the trans. I think the carrier setup helps locate the trans more than I would have thought with the rearward mount keeping the trans from flopping over like it did before?

So all in all I feel the juice was worth the squeeze but it sure sucked getting there. Hopefully I can get some time in a parking lot checking to see if this will keep the trans buzz under tight high speed left handers. The part I notched on the Kpower trans mount may still need more clearance or I could try the STI trans mount again. I'd rather keep the stock setup though. Anyway I'm done rambling for now. More to come shortly.

Since I was stuck home all holiday due to my oldest having the flu, I had a lot of time to tinker. Originally I wanted to hold off on the larger 74mm throttle body but ended up finding a tuner willing to do some stuff in stages. Anyway, with a tuner locked it was time to party. A while back I bought the id1050x injectors to leave plenty of headroom for e85 plus the built bottom end, head, and cams. While messing with the TB it seemed like a good time to mess with injectors as well.

While messing with injectors I wanted to see if moving the fuel damper to the center port of the rail would clear the intake. This will allow me to mount either a gauge or fuel pressure sensor at the end of the rail. It fit perfect.

And.... TB is installed.

I guess I should back up a little. Originally I tried the TB with my Kpower map and idle was shooting to 3k or above. It could have been a slight gasket leak since the provided rubber one in the Kpower adapter kit didn't really cover or seal the surface well. In fact when torqued it looked like it was squishing the gasket out of the sealing area. Also the ID of the TB hole with the rubber gasket was too large of an opening. Anyway, I had some gasket paper laying around so I cut up a new gasket that had way better sealing surface. The car started back up again with the higher idle so I was getting a bit frustrated. After a quick call with the new tuner he said the current map could be preventing the TB to learn and to go forward with injectors to start his base map. So that's what I did.

After uploading the new map the car settled into an idle. It felt like super lumpy and rough. Sounded weird like it was missing or something. Since the tuner was remote he checked everything over and wasn't initially seeing anything wrong. I mentioned it has to be an injector or something so he went about testing each one until we found number 3 wasn't working at all. Damn. My bargain purchase wasn't looking to be much of a bargain anymore.

Luckily I had some RDX injectors though so I tossed them in.

Immediately the car settled into a smooth as silk idle. YEEHAW!!!

A little bit of tweaking on fuel mapping and I was off to doing some logs.

I searched far and wide that afternoon looking for one id1050x injector but it seemed like buying a whole new set made more sense. After a while I started searching to see if there was something I could do to revive the one I have. It was reading correct and equal ohms to all the other three so it seemed weird it wouldn't fire. I found a youtube video of a guy saying to lightly tap the injector while spraying some fluid through cycling with 12v. Sure enough the injector came right back to life. So the next morning I reinstalled the id1050x set and we are good to go.

We are still messing with some tuning but the car feels better. Low speed and decel are tons better. Idle is better. Smoother. All around super happy. We are about to add some e85 and see how that goes. Pretty stoked.

To think I was considering getting rid of this car earlier this year seems preposterous. Really glad I managed to work through the struggle cause this car is still so awesome and special to me.
