Hey guys,

So I've owned my Z06 aobut a week now and I was thinking about getting it retuned soon since I hear the last tune may not be making as much as it could. I unfortunatley don't know all of my exact mods. What I know is 232/236 cam, afr 205 heads, longtubes, o/r x, borla catback, some intake, 42lbrs, maybe a few more things. I have the dyno sheets that say 440/416. Before I spent the money on a retune though I figured I would get some more mods, so I was thinking a fast and a tb.

I hear fast 90/90 or 92/90... which one would work the best? What size TB do I want? I want whatever would work the best. How much power do you think I would gain?

Thanks guys. I'm' lovin my new Z06!

Either FAST will work fine. You can find good deals on used FAST intakes now. I installed my FAST 90/LS2 TB and gained 19hp. So I would say you will see around 15-25rwhp.

What's the diffrence then? I mean does one make a little mnore high end and one a little more low end or something?

Anyone know the best place to buy a fast and tb?

Dont know if the 90 or 92 would make much difference on a stock size CI motor/346.... Possibly on a bigger motor... The only visible difference is the slightly bigger port opening i believe. Dont think u can go wrong either way, if i were u, i would go with the 92mm with 92mm TB. Anywhere u buy it well be about the same price... most guys have old 90mm FAST intake and they unload them for cheap... shop around on the board first...

i'd try and find a ported 90/90. or just a regular, since the ported will be hard to come across.

your biggest gains from a 95/92mm is going to be from FI or big cubes where it needs all the breathing it can get.

So would this be a good deal and a good fit for me?

That's not too bad of a deal plus you can turn around and sell your LS6 intake for $300 pretty easily so then you're only out $700.

Yes but as you said you need a clutch.

ZONick

Very true. I'm selling a procharger kit that was for my cobra and that would pay for the clutch, so if that sells soon enough I'll buy it.
