I'm excited to see the KO exhaust. I've seen a few of his fab projects but it's been on race cars (laz), it'll be good to see what he can do for a street car's setup.

He builds sexy things. I want to fondle it.

Does he know about the mt.net approved muffler? Might be worth bringing him the one that we know fits and works. Might knock a few bucks off too.

It's a little finnicky, but if you loosen the compressor v-band completely, you can slide it off the front of the turbo and re-clock it without removing anything.

Looks awesome :bigtu:

I should call KO again and let them know it is close. I only talked with once some months back and they did sound busy. I am cool with the car waiting a bit though.

I will give that a try. I may just unhook the waterlines at the rubber and loosen up the whole manifold enough to tilt and clear the shelf.

I also ordered a new flex fuel sensor. I am going to play around and mix my own around 30%. I don't need corn at these starting powers but I think it will be fun to tinker. My intention is to experiment and see some benefit with less taxes on the fuel system.

Did this. much easier than what I was thinking.

Wow what a pain in the ass pulling the tranny without a lift. I am seriously just going to pay someone to do it next time. So does this jack stand set up look sketch? Cutting the tab off with the tranny out of the car = winning.

Unbelievable sketch. Would not go under.

The 6 ton jackstands are cheap, and lift the car up plenty high enough.

I'll pull your tranny for money, if you have enough extensions on an impact gun it works well.

More like Miatapresscrew with those blocks.

That is terrifying.

Tranny is out. I survived.

Jesus, now you know why I always say to pull the motor. Its easy that way.

To be fair I really shook the shit out of the car and it didn't budge. I also kept "just in case please save my life" jack under the car.

As soon as they felt wrong I stopped and picked up a fresh never used allen. I also used a rubber mallet to tap the bracket a little as I loosened them and that did it.

Yeah I had the same experience, I tried two 4mm allens, and neither really gave me confidence that it 'fit'. I ended up stripping one, and hammering in a torx bit to get it out.. I bet a 4.5mm filed down a bit would be perfect. They're also easier to get out when the turbo is super hot.

You mentioned the low boost actuator, etc. I recommend reading the Borg Warner documentation on setting preload. I set mine to very little preload and it builds probably 13-14 psi max, then tapers off to maybe 10-11 psi at redline (no EBC yet). You also need to have the wastegate rod VERY straight to work optimally - you might have to clock the center (CHRA) to do that.

OH and you'll likely need to trim the hood brace a bit to clear the wastegate can if your car is an NA (looks like it is). I used a paint pen and painted the very top of the can, then closed the hood. This gave me a little mark, and I just cut a 3"x3" square around that mark with a dremel - very easy.

I was hoping to tune it with ebc and low actuator around 10... Well lets see how long this motor lasts. I just picked up rods, boundary oil pump, 949 water pump and ARP studs along with a begi reroute. Looks like I will be using that stuff sooner than I want. The canister looks pretty straight but we will see.

I was wondering about that damn canister hitting the roof. Guess I know now.

"looks pretty straight" probably won't cut it. You need to make sure the flapper arm slides smoothly on the actuator rod with the lower nut undone. If it doesn't, clock the CHRA until it does.

Did you max out the lift range on your jackstands or something? Ran out of notches? Cutting blocks out of a 4x4 and putting them on top of the jackstands would have been safer.

Well I have no idea how to post a damn video but I have one rocking the engine back and forth on the motor mounts without the tranny. It moves front to back very easy. Does this mean my mounts are toast?

I guess it is normal. Word.
