I have a '01 z06 bone stock and was thinking of doing some performance mods. I don't want to get to crazy any suggestions ?

Halltech vs Vortex or is there another intake better than both ?

Headers ?


Any ideas about a 3.73 gear ?

Any helpis appreciated

The general path seems to be an air intake and a set of long tube headers. I'd suggest doing some seaches over in the tech & performance section of the other forum where the questions of which headers and which intake have been debated extensively.

Mine is stock except for a Halltech Tric which cost about $750. My headers choice, were I to take the plunge, would be the TTS, with DRMs being a close second. TPIS are preferred by many.

Be sure you check with your dealer's service manager and advisor to ensure they are supportive of the mods you envision and will not give you a hard time subsequently on warranty work.

Suggest Corsa or B& B after market exhaust system! Love the sound of my Corsa Indies!

Cold Air Intake...Cat Back Exhaust...Long Tube Headers. That should burn up about $3K pretty fast.

From all of the dyno testing I have seen posted on the various forums, these do not improve performance much if at all.

I'd have to agree with the statement that cat-back systems don't make much of a difference.

I dynoed my car a while back, and there was another fellow there with a Z06 with shortie headers, catback B&Bs (i think B&Bs), and a donaldson...

His advantage over me: SIX hp

If I were buying headers, I'd definitely go for longtubes, and definitely TPIS headers. Why? Because they have a 1-3/4" primary versus a 1-5/8" primary. They'll support more flow later on.

Also, I'd dump the cats (ok, maybe go with the 02 cat setup), and pull the MAF screen.

As far as intake goes, I'm not comfortable with cutting into the radiator shroud. No, I don't have a fear of water, I just happen to live where it sometimes gets hot, and I want all the air I can get into the radiator.

Given the time, I'd build a setup that takes air from the front inlets, and collects that all, and forces it into the airbox. A completely sealed system if you will. That would avoid pressurizing the front of the engine bay (well, in front of the radiator) and probably keep the hood from lifting up and higher speeds.

If you're going to go with a bottom breathing intake setup, you might as well plug the front inlets. Chevy put those there to help the engine breathe and the expense of aerodynamics. Plugging those would make the car a bit more slippery, and raise gas milage a bit.

Of course, if I had 30k to spend on the car, I'd put in a 427 /phpBB/images/smiles/icon_smile.gif

Oh, about the 3.73 gear... With the Z06 gearbox, I'd say no. First is already really short, and the 3.73s would make it worse.

If I had the regular MN6 trans, I'd put the 3.73s in right away. I think that might even be a better setup for gearing.

what would be best is a hybrid trans...
the first 5 gears from the MN6, the 6th from the M12, and 3.73 gears. That would give a 2.08:1 overall in 6th, which just might let the car pull more rpms in 6th.

Of course I might have hit the crackpipe a bit hard when thinking about this /phpBB/images/smiles/icon_smile.gif

Long tube headers and intake (Vortex or Hall Tech) and computer reprogramming is a good start, I would also replace the stock shifter, it's poor at best. /phpBB/images/smiles/icon_smile.gif
