Devo's Extended Track #381 - 06 SS/SC Donor

[Devo]

First start today was a success! Engine sounds good but idle sort of pulses. Shut things down to correct coolant leaks on the supercharger heat exchanger and then will try to read codes and troubleshoot.

The gauge cluster showed “power steering”. I realized I didn’t have the blue plug in the picture connected but don’t see a missing mate. Where should that be in the harness?

 

[Ross]

That connects to the power steering module. Same aluminum casting that the power steering motor is connected to.

Doh! I see the port now on the Koyo box. Thank you.

I got the button panel installed and coolant leak taken care of. I thought I had the wiring right, but the horn is stuck on. Can anyone confirm the plugs and wire colors against the pictures? Separate issue is that the engine keeps running for a few seconds after the ignition is turned off. I remembered reading that others had the same problem but couldn’t find it searching through posts. Any recommendations on where to look?

For the engine run on, I put a diode in the line for the Heat Exchanger Fan. It stopped it from running about 2-5 seconds after shutdown. If you PM me your address, I can send you one as I bought 10.
I used this, but my INFO button doesn't work. Everything else does as does the button, which lead me to believe mine is wiring issue on my part and not the kit. But, take that for what it is.....

Thank you. For the life of me, I couldn't find the applicable threads. I searched for diode and now see what is needed, I may even have one lying around. I'll dig back into the button panel this weekend.

 

[Devo]

Life has been too busy. Making progress again. Found a short in my horn circuit. Installed a diode into the heat exchanger power wire, which corrected the continued running issue.

Front suspension is assembled and looking good. Still need to get the subframe in and rear suspension put together. Targeting getting it ready for a first test drive around the new year. Time will tell.

 

[Devo]

Took the week off and working towards mechanical completion. Couple questions came up:
1. Do the original tie rods from the steering rack get swapped with O32I?
2. I didn’t opt for the rear coilovers. Can someone confirm that they look correct? The cups seat nicely and the top nut appears to have full engagement, but the spring isn’t centered very well.

 

[Desert Sasqwatch]

The 'original' tie rods and rod ends go on the back of the car - they follow the front suspension onto the rear of the Goblin - and the new tie rods and rod ends from DF go onto the new front suspension. Not certain about the springs, someone else will have to comment who has used the stock springs.

 

[Ross]

The stock springs look wonky, but that is the way they are on a Cobalt.
If it bothers you, you can convert it over to new 2.5"ID springs and a:
QA1 COK104 - QA1 Coilover Hardware Kit.

If you want to save some bucks, I could sell you my used QA1 springs and coilover kit, as I have upgraded to the DF rear struts.
You can get an idea of what they look like in these early pics of my build.

 

[Jr Green]

We ended up with more threads coming out on top, haven’t cut the springs yet either.

 

[Devo]

Thanks all. I’ll get the old front tie rods moved to the rear and new kit onto the front. I’m not a fan on the fit of the cut springs but will see how it looks once on the ground. Wheels and tires will be ordered shortly.

 

[Rttoys]

The aftermarket rear struts will give you a lot of adjustability to dial in the suspension.

As I always recommend, get stickiest tires you can. You have a supercharged model, it doesn’t take much to overpower normal tires.

I can asure you it is very easy to turn the tires over and I’m in 200 treadwear Conti Extremes.

The two of you are using different nuts. @Devo is using strut nuts from the donor, and you look to be using nuts supplied with the kit hardware or sourced elsewhere. The donor hardware is much taller than what you're using.

Then go softer. The Toyo R888R’s I’m using are 100tw and really don’t spin at all. I also don’t try to spin them, but at autocross we launch very hard and I don’t spin. Now, I only get about 1500-2000 miles on tires, but those are very fun miles.

Working on brakes but getting contact on the outside edge of the caliper to the rotor. Do they need to be shimmed normally, or do I have something assembled incorrectly?

 

[Desert Sasqwatch]

Dumb question from me - can you put more than one lug nut on to make certain the brake rotor 'hat' if full flush/seated against the bearing hub face? Hard to see from the photos, looks like only one lug nut is holding the rotor in place.

 

[Desert Sasqwatch]

The reason I'm asking is the bearing hub may have a radius around the the center that interfers with the inside diameter of the rotor that can hold it away from the face.

Apologies on my own dumb question. I pulled everything apart and reseated a few times. Fresh paint appeared to be binding on the inner rotor wall. In now rotates true. Thanks for the sanity check and back to it. Getting close to the finish line.
