Hello,

I purchased a 2002 engine pullout for converting my 91 Z28 to an LS1 w/ T-56. However, I received something that I am not sure what I got. I know I can search, but at this point I need some reassurances as I just supposedly plonked down $5678 for a 33K miles pullout.

Block # 12559378.
Heads # 241.
Exhaust manifolds have EGR.
Intake #12561184.
Gas tank is plastic, any particular numbers I should search for?
Fuel lines are metal.
Is a 2002 supposed to have AIR injection, and if so, where do I identify it?
I did not receive an ECU, so I can't identify that, though I was supposed to get it.

Are there any numbers I need to search for?

I'm at a loss and a bit flustered as the company I bought it from is supposed to be reputable. Before calling them or sending off an e-mail, I need more information as to identify what exactly do I have and to basically calm down. Is it really an 02, or not.

Thank you very much for your assistance.

 

head numbers 241 are LS6 heads I am pretty sure of that. The ls6 was put in 01-02 models so you most likely have a 02. Also the intake part number is from an 02 fbody.

 

The 01-02 dont have a egr. Do you have 2 holes in the passenger side mainifold or just 1 in each side?

 

What do you mean 2 holes? I have an EGR tube coming off the passenger and driver's side manifold, running to a check valve. After the check valve, it doesn't connect to anything, it's just missing the other tubing. The tube has 2 bolts that bolt to the manifolds on either side, a typical EGR look. I also have the cats, but can only assume they aren't for a 2002 as they are bolted to the manifolds, and the y-pipe.

What about AIR? How does that look like?

 

If the intake manifold does not have a big hole in the top then you have no EGR, which I am assuming because of the intake part number. The hole in the exhaust manifold is probably just the AIR system hole.

 

Those check valves ar for the AIR system man not EGR. I would suggest that you just take all that AIR **** off and delete the codes for them in the computer, then you wont have to worry about that emissions stuff, it just gets in the way.

 

Hmm, that could be. I think you may be right, as only AIR has check valves. What does the AIR pump look like and where on the accessories is it. I can take some pictures if that helps.

 

I can't. I'm in the Republik of CA and need all this to referee my car. After which, I will pull it off and reinstall every 2 years for the smog visual.

 

AIR comes from a pump located on the drivers side right behind the headlight. It has a air hose that goes from it to the air tubes that you see on your new motor. After the check valves, the tubes should go into the exhaust manifolds.

 

Yes, visuals are required. Is the pump belt driven?

 

Nope, electric pump. Im not sure is the LT1's even came with AIR so your 91 may not have the pump.

 

The passenger side mainifold would have a fitting for the egr and 1 air tube if you have a egr. The driver side will just have one fitting for the air.

 

Thanks much, looks like I'm an idiot. At least I have a 2001+.

My 91 has an AIR pump that is belt driven. Looks like I need to get an AIR pump and ECU.

 

I have a air pump off my 02 I would sell you if you need it. PM if you do.

 

241 were the normal ls1 heads. 243 is ls6.
