My cam , pistons, compression, and rockers from the rebuild are all STOCK.......

 

ok then like i was suggesting, headers and rockers...

later when you get more money, get a cam and valvesprings and retainers and lifters and whatnot

then, after all that, get the e-cutout

 

Based on the fact your on a limited budget, just go with nitrous. Your bottom end would handle a 100-150 with no problem. Look into the Harris speedworks kits (run about $399 4 the kit)- they are a supporting vendor. Get you a mallary 685, and fuel pressure saftey switch, bottle heater, and purge valve also.....the accessories will cost a little more money but worth it. This will do more than enough to take care of the zo6. With good traction, it should put you in the high 11's no problem for less than a 700-800 dollar total investment.

Cams and Heads are good, but you have to spend the money as this isnt something you want to cut corners on...which = $$$$

 

what is a mallry 685? and a fuel pressure switch, bottle heater and purge valve? how much is this gonna cost labor wise to install?? how much RWHP would i gain from the headers, rockers compared to the NOS??? i don't see how 100 hp shot would get me 2 seconds off of my 1/4 time??

 

I dunno the details on the nitrous, but it will get you closer than the rockers and headers will... but the rockers and headers will be releasing lots of power all the time... rockers lighten up the valvetrain and also make your cam do a little more for you. once you add the cam/lifters/valvesprings/retainers, you'll find yourself in the 12s. In otherwords, you really need to throw about 1600-2000 at your car to hit 12s all day long. But spending the 1000 on headers and rockers will set the stage for the cam to shine.

You could also do a gear change to 4.56s... that makes a pretty amazing difference But you just got 373s, and you have an auto, so thats probably not gonna happen, haha.

 

How do you figure it would only be 2 grand???? with labor and everything??? what would i get for all that HP wise?? keep in mind the mods i already have

 

Mallory 685= an ignition box with window switch and timing retard built in....fuel pressure saftey switch= cuts nitrous if fuel pressure drops...purge valve= clears nitrous lines... bottle heater= keeps nitrous bottle at 900-1000psi so nitro hits nice and hard :-).... The nitrous kit can be installed by you, and will be a heck of a lot easier for you to do than the headers and rockers.....you will also more than likely have to change out your valve springs for the rockers. Call and talk to some of the nitrous people at Harris as they are a supporting vendor.


Your car on a good day should run mid to low 13's based on your current mods with good traction and 60ft. Tons of guys have done it.

Put the nitrous on, get good traction and 60ft which means sticky tires, and with a really good run= high 11's with the 150 shot. You will easily run low 12's at 117-120mph in the quarter. With you having an a4 car, the rear should be able to handle it better than a 6spd.

 

you don't need new valvesprings for rockers. headers are a little tricky to install, but rockers are really easy. easier than nitrous.

i was assuming that you would install it all yourself. i'd imagine it would put you somewhere around 350rwhp, depending on the cam.

 

Whats the altitude where your located at?

The stock valve springs are marginal for coil bind with 1.6 rockers. some have gotten by with no problems, and others have broke things. Safe insurance is to replace the valve springs

 

im located in west virginia....its about 80 and not too humid...

im getting alot of mixed advice??? im really lost....so a 100hp shot of nos is my best bet?? or....?

 

if you are interested in learning more about the nitrous stuff, try going over to the nitrous message board. I am basically giving you my input based on money/power desired, and having my lt1 car and modding since 1995 back when there wasnt anything such as long tube headers....man it was harder to go fast back then ;-). Seriously, the nitrous would be the easiest way to get you where you want without emptying the bank account. Talk to some other people over there, and then make your decision based on their input too. To basically get 12's from motor, you need the supporting mods even if you just do a cam....ie. stall converter/headers/etc (which equals a pretty chunk of change).

 

by the way....u could take your current set up...add a stall converter, headers, and rockers and get some high 12's out of that, but your not going to get the power you will from the nitrous, and your going to have more money in the converter/headers and rockers, and may only be as fast as the zo6....nitrous will bust his a**

 

So basically you have a catback, cold air intake, 3.73 gears and a shift kit. Getting rid of those huge wheels would be a big help. Look into reducing your weight if you have limited funds. Every hundred pounds you can cut will give you about a .1 in the quarter. You should already be into the mid 13's so you really only need to shave a second to reach your goal. I think you should stay away from nitrous unless you are going to build the motor for it, just not worth the risk. Get about a 2800-3000 stall converter, tranny cooler, and some sticky tires on smaller wheels, lose some weight....and you'll be in the 12's...if you have any money left pick up a set of used headers and that will seal the deal for sure.

 

just remember, if its your DD.... dont "go all out" with the stock rear end... i did and was carless for 1.5 months lol to get money to fix it(was an idiot, just spent all my money on clutch/flywheel at the time)

now i have a 12 bolt w/4.10s w00t
