Default Twin Turbo LS Build in progress

Hey all, thought some of you might be interested in seeing pics of this build. Doing a twin turbo LS conversion on my wife's 75 vette. I did the engine swap and a single turbo last year. Now I've moved the radiator forward 3 inches, fabricating a twin setup and going E85. If there's any interest I'm happy to add more details.

I'm interested in see how you moved the radiator forward 3 inches. That's something I don't recall seeing on here before.

Looks nice! Keep posting the details....

Did you do any power runs on dyno or track with old setup? What are goals for twins?

I added twins to my 555" and it's a blast!

Wow thats crazy!!! Awesome! Yeah her goals are reliability, bling and lots of jaws hanging open at car shows. Not so much max horsepower or anything like that. We never dyno'd the single setup. It worked but was too close to the hood and started to melt the paint. Hence the relocation project. Ditched the intercooler now too, due to E85.

Regarding the radiator, I made a couple aluminum brackets at the bottom, a bar across the front with large attachment plates that bolt to the inner fenders. It clears with the hood fully closed and fully opened. I will also be making aluminum panels to close off all open spaces up front, so ALL incoming air at the nose must go through the radiator, and none can go above, below, or around it.

I love custom fabrication projects. And particularly if they involve a welder somewhere in the process.
