Turbo build OR heads/cam/150 shot?

I'm fighting with myself over whether to go with a heads/cam package with ported intake or building/buying a built bottom end and going turbo.

I figure either way, I'll need a rearend.
I'll need upgraded fuel system (injectors/pump(s))

I have a built tranny already. (performa stg II)

I have never had a turbo car before, I've had a supercharged one.

I know in the end the turbo will cost a lot more, but it will also yeild A LOT more.

On turbo I'd go very mild at first with a larg(er) turbo. And continue to grow with it.

With heads and cam, it's pretty much it. Unless I build the bottom end for that I'm stuck and done... that's what bothers me.

I know I should have some ported heads for turbo but like I said I will go mild until I can push it further and further.

LS build n/a


power adders complicate things quite a bit, I would build the car to run n/a 15:1

No LSx here. I'm not doing a swap AND build.

If I ever do a LSx it'll be in an already lsx car.


Another reason for turbo, being able to lower the boost significantly so it's still possible to have fun on the street. A full on N/A build is only so fun on the street. It would be nice to be able to floor it every once in a while.

Go N/A , Only two options Elliot Port Works or Advanced Inducton, either one will take the guess work out of it.

Forged bottom end, mild "boost" cam, and an efficient, intercooled supercharger.

turbo's seem more of a headache and the cost is retardedly expensive. i would say ported heads and a 150 shot would be enough to beat a ton of **** running around on the street

No supercharger. Turbo or N/A. If I want another SC car I'd buy a regal or GTP.... which i'm thinking about already for turning into a turbo project as well...

Good AI heads, custom cam, 383, with a 150 or 200 shot should be good.

My question would be what do you want to do with the car? If you dont know where you want to go, how are you going to know how to get there?

Personally just on principle I'd do N/A, then maybe N20, but thats just me. I like playing with turbos on diesels, much easier.

I just figured I'd say "Turbo... ready, set GO!" and magically my car would be turbo'd.

Or I'd say, "Heads/Cam/No2... ready, set GO!!" And Lloyd Elliott would appear under my hood.

I've already done some extensive research on turbo setups and what it takes, I've also looked into the other route as well.

I can't decide. I'm also torn as to whether I should sell the TA and buy a Regal GS or GTP and turbo it. Less building, WAY more comfort, and just as much power... for cheaper... Plus I could work on that motor with my eyes closed.

... but the thought of having a full blown Turbo Trans Am with a roll cage is SO tempting.

Here's my biggest problem. If I go heads/cam I can have it done in months. If I go turbo, I won't have it done for years.

I'm impatient and there's also the possibility that I will lose interest along the way if I wait too long.

I probably should have said this already, but If I go N/A it's with a stock bottom end... I'll probably never do a 383 either.

If your that impatient, have no goals what-so-ever, and just want stuff to be cool, you might as well sell it and get something else. A buick or grand prix in your case. All your going to do if you dont, is buy a bunch of parts throw them under the hood, not taking the time and attention to detail to get them to work right together and waste money while having a car that isnt going to perform well. Excuse me if I'm being blunt but you dont seem dedicated to keeping the car or doing it right.

On a side note I fail to understand your " ...I should sell the TA and buy a Regal GS or GTP and turbo it. Less building, WAY more comfort, and just as much power... for cheaper... " statement, but in all honesty it sounds like you've already made up your mind.

In the end its your money so do what you want.

Wow, way to jump to conclusions. Who the hell said anything about buying random parts and throwing it together?! Cause years of prep means I'm stupid. Or trying to be cool!? And since when is a regal cool?

Well let's see, an L67 is a forged motor. So there's the less build part.

Way more comfort? I think any idiot can figure out this portion.

just as much power? Yep. 9 seconds are possible and 10s are "expected."

Cheaper? A car already built for boost doesn't need more building, only a few upgrades.

Made up my mind? Yeah. That's the whole point of this thread I posted it just to get your response to pass time.

Sorry if I come off "blunt" but you came off as an *******.
