So I'm elbow deep in the radical weight reduction and cam swap for my '70. However, the other day I was stuck in traffic next to a silver late model RX7 that had a rather large turbo. I really enjoyed listening to it for the hour I was cruising next to it. And now I have a fever...and the only prescription is a turbo.

I currently have a set of truck exhaust manifolds and the truck intake. I'd have to trade out my CNC ported and milled 241s for something with a larger chamber. Already have head studs and a MLS gaskets. The cam I just installed is nasty and would have to be traded out for a milder stick. Then there's the cutting and welding and swap to EFI.

Sooooo, either talk me out of it, or buy my setup.

I have a vic jr, 800 DP, edelbrock long tubes (one has been 'clearanced'), WCCH CNC ported 241s milled .030, Aeromotive SS fuel pump, MSD 6010, K&N extreme filter setup, a NOS kit and bottle, 4.56 gears for a 8.5" 10 bolt and the Howards Cams Duration 287/295, Lift .612/.612, 110 LSA.

ah if only it was a 6012 box :( damn it!

if your going to try to make a heavy ass 2nd gen fly, i'd go with the turbo setup. i love the way 2nd gens look, but its definitely not my first choice for a fast car. i'd rather not beat my head against a 3600 lb wall lol

I've already pulled 450lbs out of it! But I've also determined that between starting a business, working overtime at a my day job and my 2 year old daughter, this car will be sitting for a while. Might as well build it exactly how I want it and take my time, right? Get it to 3,000lbs, run as close to 600rwhp as I can with the turbo setup? I think so.

My '71 firebird was surprisingly light. It had a an iron headed BBC and a TH400 and it only weighed 3220 with no fiberglass and all the factory interior. My '77 seems to be way heavier though. Do you know what you're gonna want for that stuff?

Was going to go turbo myself, but having third gens and all the BS to make it work, I said hell with it. Going procharged, instant boost and that magnificent blower whine. Lol

In 1970 the listed curb weight was for a non-v8 car. So instead of 3200, it's more like 3450. I should be around 3000 when I'm done.

And the turbo thing. I talked to the wife about it (blank stare from her the whole time...I was just thinking out loud to be honest) and I realized that I can either put it together with what I want and be able to drive it...but I wouldn't be truely happy. And with the fact that I won't be done with it until next spring, I decided to bite the bullet and go for it.

If I remember correctly, you live at elevation right? If I lived at a higher elevation, I would definitely go turbo.

my reg lists my car as 2920...um...no. its now 3080 with the ls2 and 3280 with my fat ass in it. nothing gutted, not much aded. all aluminum motor, aluminum griffin rad, megalight bogart wheels,socketless fuel line, stock line steel removed,stock steel gas tank, battery still in factory location, full stock standard interrior. the only things not on the car are the rs grill and headlight doors and the front bumper (i think it looks much better without)

and just for refrence, the car only lost 100 lbs going from an all iron smallblock to all aluminum, and from a massive 4 core copper rad to a 2 core aluminum. that didnt thrill me lol

Nope, not at elevation at all. Pacfic Raceways is at 10 feet above sea level. Current DA is -978. Too bad you can't hook when it's 44 degrees and raining.

Well, I sold almost everything and bought a TC78 turbo and a set of 317 heads.

I still have my Howard's Cam that's perfect for carb N/A setups. And my nitrous system.

Wow, that was quick!
Good luck on the turbo build, and keep us updated! My next complete build will likely be a turbo setup, so I am interested in how you make out
