Re: 77 c10 5.3ls turbo

In parts gathering mode. Waiting for some exhaust pieces. Deatschwerks 78lbs injectors ($470) came in today along with the Innovate Wideband/boost gauge ($254). The Innovate gauge displays the AFR and boost on a signal gauge, which helps keep things clean.

Walbro 450 ($98)arrived yesterday. Still need to figure out the fittings, will run 8an lines.

On the transmission front I'm having a local guy build a th400 for it, he will also be the guy that is tuning it. Going with a 2700-3000 stall converter. He has been very helpful. A link to an old article, but he continues to turns out some crazy rides.

I really wanted to keep the a833 tranny in it but there was nothing I could do to it that would keep it in one piece. Really nice tranny, new clutch/flywheel, complete with shifter so it has some value so I decided to pull it out before I blow it up. Priced out a 4l80e and couldn't justify the price, not planning a it being a highway cruiser. I also have 3.08 gears so it will be fine down the highway with 1:1 3rd gear. Apparently 3.08 are perfect gears for a turbo car.

I'm over my target budget of $2k, guessing I'll end at $3k not counting anything transmission related. The wideband and cam are items I didn't budget for. I also have about $200 into things I've ordered and didn't need, or messed up.
