Is there an RPO code for a Formula?

I was wondering if any of these RPO codes mean the car is a Formula? I figured it might not have a code since it's a "base" Firebird, but then again it's an LS1 Firebird, not a V6, so there could be a code for it. Anyone know the deal? Thanks.

Just Googled and found WS9 and W66 both mean Formula. WS9 is the model conversion code (from a V-6 I assume), and W66 is a merchandised package .....whatever that means.

It's both ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
WS9 : MODEL CONVERSION, FORMULA
W66 : MERCHANDISED PKG, FORMULA
I haven't been able to find anything saying what the difference is between the two RPO codes, though
... Here's what I think:
WS9 is for the powertrain/suspension build-up from base Firebird to Formula with V8, and W66 is for the additions to appearance/accessories for the Formula.
Looks like the WS9 equivalent for the Trans Am is
WS4 : MODEL CONVERSION, TRANS AM
So it's the 'Model Conversion' code that's most important![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Here's some other Firebird 'Merchandised Package' ones:
W68 : MERCHANDISED PKG, FIREBIRD, SPORT APPEARANCE
Y81 : MERCHANDISED PKG, FIREBIRD
Y82 : MERCHANDISED PKG, TRANS AM
Y83 : MERCHANDISED PKG, TRANS AM GT
Y84 : MERCHANDISED PKG, GTA, TRANS AM
Y89 : MERCHANDISED PKG, FIREBIRD SE
It'd be nice to know exactly what is included in each of these packages
... Like this site has for 2nd-gen codes (not any help for 4th-gen): http://www.firebirdtransamparts.com/...ingo/bingo.htm
Firehawk codes:
B4U : 1991-1992 Firehawk option
R6V : 1993-1997 Formula Firehawk option
R6Z : Canadian Firehawk option
WU6 : SALES PACKAGE, 1999-2002 FIREHAWK UPFITTER (no Firehawks officially in 1998)
PS: This thread would belong better in the Firebird section instead of the Lounge...

uhm, yes it does. lol. your ta has it, because your ta started off as a formula. so pretty much every ls1 pontiac fbody will have that rpo. a formula has it, because it is the Model Conversion from a firebird to a formula. a ta will have it because its converted even further from a formula to a ta, and so on and so forth for firehawks...
