Looks great! Can't wait to see this one come together.:thumbsup:

Todays update : The heads on the ZZ572 has the standard amount of boltholes to fasten the manifolds, but also two additional boltholes exist on the heads. I want to utilize the additional holes so I drawed the exhaustmanifoldflange in Autocad with the additional holes, and got a local shop to lasercut the flanges for me.

We cut a thin piece first to see if the flange aligned correctly, and it did, tomorrow I will order the finished flanges in 12mm 316 grade steel :)

Awesome project!
Nice to se some adwanced skandinavian projekts!

Keep it up and keep us posted!

let us know more about whats going to be done with the frame... I want to do some mods on my 67 frame to make it more ridgid.... Great set up..:thumbsup:

Blessings,

I have not decided yet, but I have some ideas that I will discuss with the chassibuilder in a few weeks. When the frame is done, I will post pictures of it and you can see what is done to it :)

Todays update : I picked up the exhaustmanifoldflanges at the machineshop today. They look nice :)

They're made of 316 steel, and 12mm thick, after we have tig-welded the manifolds we will put them in the grinder, and get a straight surface for the gaskets.

Flanges look awesome. I will be checking back to see progress. Love the project so far. :hail:

Awesome project! It's hard to believe that such a clean Chevelle can be found in Norway without having to ship one from overseas. You are very lucky. And it's great that you had the opportunity to drive the car for a while before tearing it completely apart.

One suggestion: Look into the trans controller from Powertrain Control Solutions. http://www.transmissioncontroller.com Their product is very well suited for turbo cars as it allows for dual load sensor inputs--MAP and TPS. You can set it up such that the transmissions shifts a bit more mildly when the controller sees vacuum and then aggressive when the computer sees boost from the MAP sensor. So it will gather load data from both the TPS and the MAP using one as the primary input and the other as secondary input for very accurate and reliable mapping. Not a necessity, but useful. Perhaps Compushift can do this also.

When I had welded my headers to the flange (GM LS1 Flange pretty much the same as yours) it was still straight and I didn't need any grinding on them. If you're careful you might get it straight as it is.


Gonna be a cool car and I hope to see it next summer.

Todays update : I picked up the turbos the other day. Here are som pictures. Last thursday I shipped the frame to the chassibuilder who will do the neccessary work on it, I hope it will be ready in a few weeks.

I'm travelling to California and Las Vegas in about two weeks, and will be in California and Las Vegas for 2,5 weeks. So I wount be needing the frame before I get home... :-)
