What should my build be? I have a completely stock (except for full exhaust) 1999 Trans Am WS6 6-speed. I would like to go low 10s in the quarter while having a complete street car (full interior, street rims, etc.), but I wouldn't mind losing the heat and A/C. I have budgeted $17,000 on this build.
Where should I spend my money and how should I spend it? I know I'll need a motor (forged 347 or should I go bigger?), a 9-inch, a clutch, build the transmission up some, but beyond that I don't have a clue. Would turbo or a procharger be better for me and what setup should I have? What heads? What intake manifold? I'll be getting a front mount intercooler as well. I have appropriated roughly $4,000 for labor, which leaves me $13,000 to spend on the build.
Any help would be greatly appreciated.

You could always give me your TA and $12,000, and take my 2000 Turbo Z28. It has already gone 10.91 @131 on 315 BFG DR's. It would save ya alot of money in the long run. Trust me on that one. Heck you could take the $5000 you would save right off and buy a 4L80E and some street rims too.
On the other hand. 10's you will need at a minimum a decent short block (347 will be fine), Fuel system (dual Walbro intanks), capable trans and rear (built auto or 6spd and a 12 bolt or 9 inch) , and a basic 6.0L manifold turbo setup. I favor turbo setup's. Alot of guys have done it with superchargers too.
Use the search and see what some of the combo's are putting down. Check out the boosted list. Mine is post #37. My number's and ET's were on 10lbs of boost with a crappy 1.8 60'.

I would go with a pro charger d1sc I am partial to these of course. it is not to hard to run 10's these days even in full street trim, with d/r's of course. I have gone 11.1 in full street trim and there is a mid 10 second pass in it if I could get my 60 under a 1.9. Im running a stock size built motor so you wouldent have to go with more cubes and save the money for the rest of the setup.
I'd reuse your block and crank, adding forged rods and pistons.

a PST Driveshaft http://www.exoticperformanceplus.com....html?item=541
A Spec Stage 3+ clutch and pressure plate, BMR subframe connectors, BMR Xtreme torque arm and a BMR Xtreme anti sway bar.
I'd also get the transmission rebuilt by RPM Transmissions

I think turbo set-ups are nice but tend to be more hassels, work and money. I chose the D1 route but havn't had it to the track yet. With my power level I don't see it being a problem getting into the tens. Even with my set-up though, I'm pretty sure I'm over your money limitations and I don't even have a built block or tranny yet. By the time you add up all the supporting mods like all the bolt ons, heads, cam, valve train, susspension, rear end, transmission, wheels, tires, fuel system and a good tune, it gets very expensive. Then add a supercharger kit. I've got to be in the high teens to low 20s and I'm still going to need to drop another 5-6 grand on the block and tranny. Turbos are going to be even more. I even saved a bunch of money by installing everything myself. I don't even consider my car very street friendly. From what I've seen a 10 second street friendly car is very expensive no matter what route you choose. It is a great hobby though and I love my car so it's worth it for me. Just make sure you plan it out and if you have to take it one step at a time it will get there eventually. Mine started out with an air lid and the addiction began lol, 4 years later here I am.
Well said. I have 3 times what my car is woth invested in to it. If I sold it right now for $20k I would lose the better part od $14-15k. Thats part of it. Its a expensive hobby. A hobby that I love. So its worth it.
Truth be told, with your 10 second goals. I would do a forged stock cube motor with a MS3 cam, FAST 90/90 setup and a shot of nitrous. I would keep the stock heads and just upgrade the springs. Get a good clutch and rear and enjoy the car.

I think nitrous would be much easier on the check book, you wouldent have to spend the 5000 for the blower. I could be way off on this but if you were to go with a wet kit you wouldent have to spend as much on the fuel system. Maybe someone can chime in on this for sure.

Let's see, if your rules are: must go mid 10's in street trim, street friendly, dragstrip and autocross usable then you could really do any of the above. It all depends on which one is most important to you. Nitrous isn't going to be autocross friendly, due to bottle limits. Turbos aren't really autocross friendly unless you want to spend a lot for a good twin setup (best route for autocross turbo IMO). And if you go with a twin setup built to be friendly for autocross you probably won't get as much at the dragstrip with them as you would a centrifigal (sp) So having weighed the cons of those I would say that a s/c would be your best bet. Now up to this point most have recommended the D1 setup, but I still like old school stuff. So why not got with a roots setup. Completely streetable, with minor engine mods that you have already said you are comfortable with. With the positive displacement it should help with the idle lope of a bigger cam. Nice smooth tq curve for autocross and good for the shortend of the dragstrip. Now if you were to do this I would say make sure that you get reputable parts. And talk to the pros. I have seen a lot of roots setups that were thrown together poorly and didn't work worth a damn. Also as an added bonus Just like the centri setup you can do a pulley/belt swap and be completely streetable again. Just my .02
That sounds reasonable, but it's not that easy to run 10s. That sounds like a nice fun street set-up that runs 12s, maybe high 11s. There are a lot of guys on here making good power with superchargers and turbos that still only run 12s. And thats because it's not just making the power, it's more about being able to use it. 10s are no easy feat. If he set's his goals a little lower, I think he has enough funds to have a fun streetable 11-12 second car.

So you don't think that you can go mid 10's on a roots setup? I am not trying to make assumptions but that is how I am reading it. I think it is really reasonable to go tens on a roots setup. Now to do that you would definately have to go forged and cube it out some with a decent head cam package, but I don't see why that won't put him all over the power numbers required. He said he was comfortable with forging it and putting decent heads/cam/intake on it so the only addition required would be the crank. Which shouldn't be that much more. Tuning and all the other things still apply. And for simplicities sake he could put a roots setup and add spray for getting in the tens. Then he would still have plenty out of the blower for the other applications.
well... not many roots blowers are avalaible for the F body, and they have a hard time fitting in the engine bay... Maybe if he was driving a Mustang, or a corvette, but its an F body.... Add up the combo you were just talking about... roots blower, forged bottom end, heads, cam, Headers, Exhaust, Fuel system, tranny, Rear, Suspension, tires.......
That is a fortune, and that doesnt include installing the parts and the tuning... And how often are you going to need 500 horses for auto-X? Honestly, you WILL be driving this on the street much more than the track, and may never see the road course, for your modest goals and budget, I would probably run a Cam/Heads set up, Fast 90/90 and a nice nitrous kit... Its not as sexy as a turbo kit, but come on.....
But if you want to learn the hard way, then spend spend spend, and just realize in the beginning that a turbo set up is not an easy goal for the weekend hobby mechanic... there is so much to understand and so many variables in the design and execution, and it is extremely sofisticated... not to mention expensive...
or just buy one of these twin kits from a sponsor... GenTT or APS or even Speed or Futrall or Stenod... whomever... STS would even get it with enough money.. but anyway....

Some of you guys are only looking at the amount of power it takes to get in the 10's, that can be done easily with what he has to spend. Just because you have enough power to be in the 10s doesn't mean your going to get a 10 second pass, you need to be able to support that power and get it to the ground.
