Been traveling quite a bit, but got a little time today. Fanned up a combine IM support brace/LSx coil bracket. I need to figure out what the wire solution is for VVT. Sadfab looks like they have something, but I will need longer wires. I know I can get Magnecore to make a set, but will they know what boots to use? More reading is in order.

Finished off the belt tensioner, which was more work than I anticipated. Also made it through a few of the details with the supercharger stuffs. The SC is essentially done now. Time to move on to the IM, ignition, and fuel stuff. Then to the hot-side.

still hoping somebody can chime in with some suggestions for the spark plug wires. I see Emilio hogged the channel on the VC out for one of his cars. That might be the way I go. I may also contact Sadfab to see if they can do something custom for me.

What time? I am heading the High Plains for the SCCA stuff they have going on. I suspect we will be back mid-afternoon.

Never worked right. Messed with air flow through the valve cover. Every engine we ever ran with that cover had blowby. Went back to a stock valve cover and blow by issues went away. Until TSE finishes their NB2 COP bracket, LSX or OEM coils are the way to go.

Why is it that Begi decided to use M10 studs for the turbo as opposed to M8? The housing casting interfered with a standard M10 flange nut, so ...




That makes me a sad panda.

lucky for me the Alpha Tig with a 5L cup is bomber even when my skills are not.







getting closer

Updated my electronic throttle body controller based on some suggestions from Oreo. Thanks Oreo!

Got some time on the car today. Welded bungs into the VC for the oil pressure regulator and a crankcase pressure sensor. Mocked up the oil supply path. I source from the VVT solenoid housing through a restrictor, a filter, and then to the regulator, which shunts through the VC into the head.

Also fabbed up a throttle cable bracket and mocked the fuel rail lines to see what fittings I need to order there.

random tomato-**** pic, the current 2017 Colorado record. Hope it holds on through the rest of the season.

Like a peach! On the second to last Wednesday drive, through Squaw pass, I was in the heels of a AP1 STOOK, all night!

So, as hard as it is for me to abide by the "ain't broke, don't fix it rule"... I decided that the turnbuckle solution form the 1.6 setup worked well enough to reuse instead of making a new bracket to mount the stock alternator upper bracket.

cranked everything tight and it is true and solid.

The 1.6? I'm not, just the alternator bracket. I was going to make a new one, but the turnbuckle works well.

I am starting to think about what is next, and the 1.6 in a different shell is appealing. It was wicked quick when I took it apart, and with rods I think it would embarrass all but the top tier 1.8s. The autorotor can handle higher PRs than the MP62 I am using for this build.
