My car runs 13.2 right now on hard tires. With slicks, I'm expecting no worse than 12.8, given the same conditions.

My target is mid-high 11's on 93 octane and drag radials, with near-stock drivability, road manners, and fuel economy being the biggest priority.

I plan on installing a good clutch, a 12-bolt with traction control, SFCs, and the works as far as suspension goes.

What should I do for power? I'm thinking headers and a tune for now, and a turbocharger with adjustable boost down the road.

Other ideas and thoughts?

what budget first? gears, h/c, clutch, ssra, many to list

 

You'll either need to bust out a nice H/C kit and basic bolt-ons, or do ALL the bolt-ons.

LSX intake, ported TB, LT headers, ORY-pipe, cutout, pulley, gears...

The bolt-ons will be the way to go if you wanna keep good streetability (a cam could take away from that) Only downside is you'll need a good combo of mods, and you'll have to drive the **** out of your car for mid-high 11s with only bolt-ons. You'll also have to think about doing some weight reduction. Most of it is free speed. You can get ride of stuff in your interior, get light-weight suspension parts, get ride of your AIR and EGR systems (if your state doesn't do any testing)

 

Ha, I think you guys missed where I said turbocharger. I don't plan on 11's until then. I'd be ecstatic to get below 12.5 on slicks before I get some boost. Seems like I ought to be able to shave a second with boost, don't you think?

I already have an LS6 intake manifold -- it came stock on '01 and '02 LS1 cars.

I'll get 3.73's in my 12-bolt. Until then, my 3.42's will do fine. Not doing 4.10's for economy considerations. I know they'd help my times, but this is not going to be an all-out drag car. I'm going for balance. It's my daily driver! Fast in a straight line, fast through the turns, and easy to live with. Not overwhelming on any of those counts, but good. No weight reduction, either. I'm just looking for stuff to do in the meantime, before I can afford that turbo. Maybe shave a couple tenths.

I don't have to meet any emissions requirements in Michigan, but I'm keeping the cats for smell reasons, and because it just seems like "the right thing to do" morally. Environment and all, you know?

If I do heads/cam, it would be mild. Just enough to support the turbo down the road. I don't want anything too harsh. My wife drives this car! (And yes, I would trust her to drive an 11-second car).

 

Rob,

If you read my previous post, I already said the gears will wait until I get the 12-bolt.

4.10's will result in a 20% increase in revs at any speed; 10% for 3.73's. My Corsa exhaust is quiet below 2000 rpm, and right now that means I can do about 90 in 6th without getting any exhaust drone. 3.73's lower the limit to 83mph; 4.10's lower it to 75. Since I routinely cruise at 77-80mph, that makes it easy to decide on 3.73's. The #1 priority is to keep the car livable.

I realize that I'd be replacing the headers. I'm just not sure how far down the road this turbo is, and I'm feeling a little impatient. I'd probably buy something used in the interim, since I know I'm going to replace it.

I picked a turbo because you can adjust boost pressure on the fly. I don't want to have to swap pulleys or anything like that. I'm no expert on turbos or superchargers at this point (just learning with the GN) -- what benefit would I get from a centrifugal blower?

 

well the centrifugal blower is a lot easier to install and it has the ablility to change the impeller size and to spin the impeller at diferent speeds which allows flexibility in the whole power curve. That is what is nice about super charges, they will proivde boost at any rpm since it is belt drivin. Also as far as i know there very much lag.

The turbo is a little more efficient because it isnt belt drivin. All i have to say is with those sts kits.... one exahust pipe makes me a little sad

 

Remote mount turbo. Relatively easy install, and you can still use headers.
