The Wife wants to go faster @ the Dragstrip - Turbo Build

[HAULIN IT]

Vile, You must have skipped over this post.

Guys, Here's the basics of the plan. The truck is going to be a rolling testbed for my turbo set-up since it is in one piece & has been tested a bit at the track. I've been researching & gathering parts for over a year now...real fab progress won't start for another month or Two
due to being crazy busy at work.
 The turbo engine is actually for my '73 Vega that I bought in the summer of '87. It's been in the back corner of my garage since '89.
 I'm going to build the headers/hotside, coldside, ect. in the Vega then transplant it all to the truck for testing. As long as Chris doesn't mind some "car" underhood shots on here, I'll post the build as it goes together...otherwise once it's in the truck you'll see pic's.
 The engine is a basic steel crank, forged rods/piston 355 Chevy, the turbo is a T-6 based Bullseye Performance 80mm. I'm working on a Holley 750, modifying for blow-through. That's about it for now...should make the "Black Box" a little quicker   Lorne

I'm hoping to have the turbo set-up done in a couple months & pull the Olds engine after the Olds Nationals in July. I'll check the bearings, ect. & sit it in the corner until I'm done testing the turbo engine or if I have trouble with it close to September...I'll stick it back in for DragWeek if I have to.
 The truck will be ideal for testing since we're used to running it & it's wide, long & heavy compared to something like the Vega.
  All of the guys I talk to that have done turbos, say it's like addicts on crack...pretty soon you want a turbo daily driver, lawn mower, ect. So the truck may get a turbo Olds before it's all over...who knows?
 As for the parts, they have come from several places. The flanges came from CPR, most of the bends came from Chassisshop, the V-bands came from Racepartsolutions. The 45* bends for the headers & the BIG bends for the downpipe are from Heart throb. I'll keep everyone posted, Lorne

Sweet! and yeah I had a brain fart there.

Once you Turbo it, you WILL be turbo'ing EVERYTHING!

[ThisisnotRusty]

I can't wait to see this. How much power are you looking to get?

[HAULIN IT]

Well, Progress has been slower than anticipated, but I did make a little ground in the last couple days. I finally took the time to get the headers built...I just need to drop them off to get the flanges surfaced. I'll post more as things progress!

Where are you getting your band flanges?

[HAULIN IT]

Racepartsolutions, They are US made by a company - Five Star. They have a groove on one half & a lip on the other half around the center hole that keeps the Two parts aligned while installing the band...they seem to be nice, heavy quality, stainless steel band. Lorne

[Captkaos]

Thanks!  I am trying to find some for my setup.

[HAULIN IT]

Got a few hours here & there to get some port work done on the heads. We're going slow...but a little progress is allways good. Lorne

lorne and cap, check those band clamps for fitment and the bolts, out of the 5 weve gotten from them 3 were perfect, one didnt seal correctly, and the last one the nut was cross threaded and bound up. we're having a hellofa time finding a reliable source for them.

[75ChevyGuy]

Those headers look amazing! Can't wait to see this thing all together.

[HAULIN IT]

Bringing this back up...Project is not going near as fast as I'd hoped (Does anyone's?), but still making a bit of headway.
Got my Wastegate & Blow-off valve the other day...they are JGS 50mm units, American made good stuff. A piece here & there...one hour at a time. I have a machinist friend making some stubs with the flanges included so I don't have to have Two welds a couple inches apart or end up with a step from the tube to the flange. Lorne

Lorne if you're looking to get your hot side coated, we use a place called QC coatings in michigan, super reasonable (down right cheap) and they actually warranty turbo stuff.

Russ, Thanks! I have seen where a few guys have used QC with good reviews. I do plan to coat the headers & the hotside tubing...I'll have to check them out. Lorne

What heads are you starting with? I looked through the thread but didn't see a casting number. (I admit I could be missing it tho)
