Readymix EJ22T build thread...

Not sure yet, I'm broke. The PPGs pretty much killed any spare money I had

 

Blah blah blah. You know what happened. EJ257 w/ Mahle's swapped in. Hit the dyno. Fueling issues.

Car was running fine up to 5750rpms, then the AFRs would skyrocket to 12.5:1. Even after Clark took the gardenhose approach and set the Injector duty cycle to 97% to compensate for it.

One of the techs at LSE and myself sort of agreed that it was likely the fuel pressure regulator. I picked one up from MTKA Morries Subaru the other day and finally got around to swapping it out.

Short answer, yes, I think it fixed it. Tom will have to log AFRs to confirm, but I think I'm in the clear. Before swapping the FPR, I would get a knocklite flash at 6000rpms @ WOT. Now I can roll it out to 7000rpms with no knocklight indications. This is a good sign. Too afraid to stare at my rearview to see if there was black smoke from running super rich or not, but I'm assuming I spit something black out the back end. We will check AFR tomorrow to see what happens. Clark said he'd have no problem altering my map accordingly.

Bad news though, it appears my Koyo radiator is leaking at the petcock. I need to pull it off and wrap it in teflon tape or something. I'm hoping that is where the leak is and not a crack in the welds (unlikely). Once the car cools down I'm going to give that a go.

 

??? What the hell are you trying to say ??? That makes no sense. I have a Koyo Radiator. Says Koyo on the top of it.

 

I wouldn't pull the whole radiator, I'd likely just have someone plug the hole with their thumb while I wrap the petcock in teflon tape, then toss it back on there. I'd probably lose less than a gallon of coolant in the process that way. Otherwise, I can jack the car up on the passenger side to slosh as much coolant as possible away from the hole. I have the petcock as hand tight as I can get it, I may take a pair of needle nose and try turning it some more, but the petcock is plastic, so I don't want to wrench it off or break it in the process of doing this.

 

Checked the petcock, gave it a little 1/4 turn with the pliers. Leak fixed. Now it needs a bath

And one of my downpipe bolts fell out again Those things are a pain in the ass to find.

 

Now I have misfires from 3k-4k WOT in 4th gear. Not sure if this is a over-fueling misfire though or not. I'm going to have Tom log AFRs tonight. I'm thinking the misfires might be caused by the increased fuel flow causing things to run too rich. But I could be wrong on that one. It feels kinda sluggish, so who knows.

 

Agreed. I'll see you down at the stonez. We'll get to the bottom of this business.

 

QFT!

 

Yes, if you're a meat fisted goon, you will wreck a PPG gearset.

 

That's why it is imperative to "cull the wheat from the chaff...CULL THE WHEAT FROM THE CHAAAAAAFF!!"

 

I was in the future, it was too late to RSVP.

 

Is it possible for me to get a ride in this thing when it’s done?

 

It’s science!

 

Maybe I could take it to HIN when you button up the punch list?

This thread is educational!

 

I can relate to the btw.

 

FTW-furry toilet wookie

 

Is this car done yet?

 

Oh wow, there's a blast from the past. Bet you're kicking yourself for fawning over those clearly inferior PPG gearsets in hindsight eh?

 

BOV=Black Out Valve?
