That's going to be perfect. After I did mine, I noticed the throttle is a bit touchier. I dialed way back light throttle response in HPTuners to combat it.

Yeah when I saw that post, my response was, "I wish someone told me that before I got the drill out!"

I did it head on. There's 110k on my stock motor, so I don't have as much invested as your built motor. There is a passage where you can see the area. There were a couple shavings I pulled out with a dab of grease on the tip of a screwdriver. I saw somewhere, maybe FB group you can also just...

Josh, sorry I haven't replied to your message. I was trying to find pictures of the hole I drilled, but I'll look later. Essentially, I drilled an 1/8" hole in the aluminum of the head right in the middle of where the LSJ gasket PCV hole is. The LAP head still has a void inside and allows...

Bump, reasonable offer will be accepted. Hate to have this hanging on the wall.

I just had an autocross event yesterday and I get what you mean. It's almost as if the vacuum booster is a regulator itself and as you push on the pedal, it increases vacuum. When you have a lower input pressure, you have normal assist until you hit that level, then the assist doesn't increase...

I know this isn't exactly a Cobalt part, but there's lots of Ecotec members here who may be able to help. I'm looking for an F23 with the 4.17 final drive. This is out of early HHRs. Within a 4-5 hour drive of 53913 preferable. Thanks!

This was my problem. In my case, it was the crank position sensor wiring. I ran new wires to the sensor from the ECM and my problem was solved.

After a few days of driving, I can confirm it sounds amazing. Completely eliminated rhaspiness and has a real muted tone. Cold start is mellow and idle is nearly silent. Still gets rowdy when on it, though! Will post components and cost in my build thread.

For sale is a 3" exhaust as build by DF. I got this a couple years ago, but found it to be too loud for my liking. Has a high temp silver spray paint on it. Baked appropriately when applied. I noticed a decent power gain on my 2.2 supercharged when I went from my 2" to this one. Warning: it...

Not to bump an old thread, but here's the direction I took for quietness and better support to reduce hanging weight. More info can be found on last page of my build log. Super happy with it so far but have yet to drive it. The rhaspiness is gone and I love that it's supported by the frame...

I completed a big step almost a year in the making today. My biggest gripe with the Goblin always was the exhaust. It's loud, it sounds like a tractor, and it's not exactly eye candy. Two years ago I found a single in dual out Vibrant muffler that seemed like it could be a good fit. I bought...

The crank signals may be different between an LE5 and an L61. Will have to figure out which computer to run it with. Also will probably have to drill a hole in the head for the PCV for the LSJ supercharger manifold.

Does anyone know if DF has released the drawing so a new windshield can be cut via CNC router or similar? I'm not super confident in my jig saw skills.

Found a set! Thanks! I'd like to pick up a fender set and wondering if anybody has some and isn't planning to install. At this point, any of the three width options would work for me. Can pick up within a couple hundred miles of 53913 otherwise would like shipped. PM me price. Thanks!
