What are the rpo codes that I need to look for on a typhoon? My dad just found one for a steal and I want to do my due diligence of finding stuff that would dictate a true typhoon.

They were converted after they left the factory, not sure if they have any special RPO codes. What's a steal? Typhoons are not worth anything near what a Syclone brings.

Ok that's a steal, but at that price I figure it's going to need quite a bit of work, real or not.
The body is in good shape, it has been swapped with a 5.7 out of a corvette, it runs and drives, still has awd, problem is, he said it squeaks LOUD towards the bottom of the engine. I believe it's nothing big, but for 1500....

I'd say it's not a true Typhoon unless it's original. The turbo 4.3l being the biggest thing to make it special.
10-4. Would you still say 1500 would be decent since the body isn't all beat up?
Would the typhoon cladding be good to anyone who may need it or is it just one of those things that people aren't looking for?
Dad likes the way it looks and was just asking me if it's worth 1500? I say yes, but I want opinions before I talk him into wasting his time and money.

Show us some pics.
I'll get dad to send them in the morning. When he gets up. Like I said earlier. My dad found the typhoon. I just want to know what to look for other than body cladding. I will update as soon as I get pics

The cladding if it's all there and undamaged is easily worth more than $1500 as individual pieces to sell to someone restoring a certifiable Typhoon.
Which year is the one you should have already bought.
Since the Typhoons were final assembled outside a GM facility they have unique vin numbers.
1992 TYPHOON – 1GDCT18Z1N081xxxx
1993 TYPHOON – 1GDCT18Z1P081xxxx
The xxxx is the four digit series number ranging from 0001 to 2497 for 1992 Typhoons and 0001 to 2200 for 1993 Typhoons. That last four number was assigned by Production Automotive Services (PAS) in Troy, Michigan. who actually did final assembly of the Typhoons.
That number, with last 4 filled in, should also be on the PAS Decal – Located inside driver’s door jam next to door latch pin. Only a certified fool would have removed that door jam decal. The number on that decal should match the number on the dash vin tag under the windshield and the Glovebox SPID Decal – Located on the bottom of the inside of the glovebox. The SPID should also have the RPO code LB4 for the vin Z engine they left Shreveport with. PAS installed the turbocharged engine, but the truck was still identified as an LB4. A True Typhoon also has to be one of these color combinations:
1992
Black w/ Black (1262 total)
Black w/ Gray (130 total)
Frost White w/ Gray (518 total)
Apple Red w/ Gray (345 total)
Bright Teal w/ Gray (132 total)
Forest Green Metallic w/ Gray (82 total)
Aspen Blue w/ Gray (28 total)
Radar Blue w/ Radar Blue (2 total)
Raspberry Metallic w/ Raspberry Metallic (2 total)
1993
Black w/ Black (1,008 total)
Black w/ Gray (98 total)
Frost White w/ White (532 total)
Frost White w/ Gray (115 total)
Apple Red w/ Apple Red (77 total)
Apple Red w/ Gray (101 total)
Forest Green Metallic w/ Gray (210 total)
Garnet Red w/ Gray (24 total)
Royal Blue Metallic w/ Gray (35 total)
Radar Blue w/ Radar Blue (1 total factory test color truck )
These are the experts you should be asking:

Just don't tell them where it is located or any other identifying info or it will not be there tomorrow.
BTW everyone who ever put a 5.7 in a 1st gen says the engine came out of a Corvette.
If you do buy it and need to replace the squeaky engine, whatever you do do not put an LS engine in it. The correct engine from a 1992 -1993 Corvette would be a 1992 or 1993 LT1. You want it to appear to be from the factory and that was the only GM engine offered those 2 years. Sort of going Typhoon one step better. A 6 speed would be spectacular, but getting it to connect to the transfer case could be a nightmare. Too bad the 92-93 4l60E were the first and worst years of production. A good tranzman can fix that.
Or did the PO do something dumb like a TH350 when he installed the "Corvette" engine?

ODS... nice work. Copied part of it to use to solve a problem looming with one vehicle.
On Sort of going Typhoon one step better. I love that. Had a '63 Impala SS that that was all dead original but had had it's original engine replaced with a 283; I put a warmed over 400 SBC in with all the trimming to look like an original '63 corvette motor. Ran good, and it was fun to hear observers wonder if it came that way. Lot of fun that way.

No one answered the OP's question: "Is there a specific RPO for Typhoon?"
Yes, there is. Z79. Syclone is ZR9.
The VIN number which was assigned by GM, (not PAS) has several unique identifiers in it:
The 3rd position "D" Is GMC Incomplete. Only a SyTy has a D in this position for 91-93 T-series.
The 12th position is an "8". This is the leading digit of the Sequential number. The 8 denotes the beginning of the sequence unique to the SyTy for the model year.
The 8th position "engine" is the same "Z" as the LB4. The SyTy engines were assembled from long blocks produced at Romulus and Tonawanda by PAS and shipped to the assembly plant for installation on the line by GMAD. The trucks ran and drove when completed at the assembly plant. The machine code for a SyTy engine is "*LD" where * is last digit of the year model. Ie, a 93 Ty engine is 3LD, found on the front pad below the A/C compressor.
