well i'm just about to buy a 99 FRC turbo vette and im a muscle car guy( i got a blown 67 camaro), so i'm not really sure what to look out for on one of these cars. First here are the specs

nassau blue 99 frc vette - only 200 something of this color FRC i guess
ls2 block
lq9 stock rotating assy(guess it lowers the compression to 9.5)
l76 heads untouched
patriot dual gold valvesprings
l76 intake
2003 z06 cam .552 lift
arp rod bolts
cerra t72 single turbo kit
2007 z06 clutch

here are other goodies on the car also
6speed
c6 z06 painted 19" wheels with 305 tires on the back
c6 z06 brakes
c6 seats

the car comes with a meth injection and innovate LC1 wideband not installed.

the car has a few issues that need to be worked out, but i'm willing to deal with them at the price I can get the car for.

Here is a pic of the dyno graph, it needs a tune.




I forgot what it was called but it comes with one of those things that allow you to change the settings of the computer on a laptop. Dr. Phil is right down the street from me so i'm going to have him tune it for me.

now how much power would I be able to get out of this car reliably, how much boost? I want the car to be on a real safe tune, but that doesnt mean I don't want to turn up the boost as much as I can safely.

How much power could I expect out of the car?

Is there anything with the components selected I should be careful about?

Looking for any opinions or info...

thanks!

Where do you live? That car looks like it needs some major tuning work is all. Might have everything else in line to make good power. I would say 500-550+ to the tires on pump gas should be no trouble at all.

The Z06 cam works ok for turbo cars. I know Parish8 picked up 100HP on his turbo buildup when he did a cam swap to the Z06 cam.

But, in the case of this build its matched to a set of L92 heads which I personally haven't seen a test of together. All the forced induction cars I've seen using them use the older style cathedral port Ls1/Ls6 style head. Its not to say someone hasn't done it, I jsut haven't seen a test of it together. It will be interesting to see how the much bigger port L92 heads paly with the stock Z06 cam.

The LQ9 stock rotating assembly would be my biggest area of concern. This sounds like a build based on someone's left over parts. The question I would ask would be why use a stock used LQ9 rotating assembly in an LS2 block.

Anyhow, I would say the car needs some serious tuning, and the power is way down from where I would expect it to be. The other issue is that Cerra had a lot of issues with its kits which is why they aren't around any more. You have to go back to 2002 and you will find a lot of "Cerra sucks" threads. I did find one thread on Z06vette.com which might give you a point of reference though on what to expect.

Cerra Racing T76 GTS Single Turbo Kit
A&A FMIC Kit
Stage II Heads
9.25:1 Compression
Stage II Heads
MTI B1 Cam
94 Octane and Torco

Just the facts:
14psi
648rwhp/638rwtq
12 psi
602rwhp/556rwtq

The Ls7 clutch will hold about 450 RWHP. But, if you don't put a sticky tire on it or try to drag race it you will most likely be fine.

I would say that along with the stock bottom end would be my only areas of concern. But I would think once tuned up it might make a really fun low budget build. If you ever had to re-do the car I would look at forged internals and an upgraded clutch if the the LS7 doesn't hold.

Yeah, I was a little confused on why someone would go the trouble of stuffing stock LQ9 internals in a LS2 block, that would have been a good time to do rods and pistons.
I wonder how a C6 ZO6 cam would fare with the L92 heads in a boosted application. Might be a little better matched with these heads then the C5 ZO6 cam, could be interesting to explore that one.

lq9 pistons (flat top) = 10.1:1 comp
lq4 pistons (dished)= 9.5ish:1 comp

My numbers aren't exact but should be close.

seems as if they half assed the build a 72mm on a 6.0 seems smallish i would have atleast done a 76

plus the rotating assembly seems crappy for a "build" **** spend a little atleast get some decent pistons

power seems really low for a turbo car hell my old zo6 with just a cam and exhaust made over 420

i think its still a project in prgress so if you want to put up with it its your call

Wrong turbo is the first problem. Power drops off sharply even well before 6000rpms.

Is that taking into account 70 cc chambers on the L92's?

Is that the car that was posted on Motown not long ago?? clean looking car for sure! Depends on the price, but it looks like a nice car and sounds to have some decent parts. It's a good start for another project car
