ok Well I just got in the mail today was gonna bolt it all up. I noticed where is the thing for the IAC..Then read some of the directions and it says you need the OEM collant passage thing. Well my problem is I sold my STOCK TPI stuff about 2 months ago so I dont have that OEM thing. What do I do about this? Where can I find this water passage thing on the bottom of the throttle body and also thats where the IAC goes I believe.

 

Sorry I forgot its a holley throttle body.

 

You indeed need the IAC housing. It's dealer only part. You also ay need the top plate, aftermarket TB's don't come with nothing. Sucks huh? I had almost the same problem.

 

What do you mean top part? I have the part on top that says holley. Its a metal plate...where do I get these things and how much am I looking at? price wise? Also whats the correct name for them so when I ask for them?

 

Just as John said, it's the IAC (Idle Air Control) housing. Its available at your local GM dealer or anybody that handles Delco FI parts.

 

anyone have a part number in case they give me look

 

I just tried to look up the part number in my 1990 Camaro Parts ans illustrations Catalog. Same thing the dealer used.
I have bad news, the part number listed is "N.S." which means not serviced. Translates to you must buy the whole throttle body to get the "IAC Coolant Housing".

 

john lingenfelter sells them sepratley for his tb's..... i'm pretty sure they will fit yours.......

 

Or just get a stock TB for 30-40 bucks off Ebay and use that.

 

where can I buy the john lingenfelter bottom piece? and will it work with my holley throttle body? I would just buy a used piece, but I figured if im gonna spend the moneys I mys well just get a new one. Plus it would look 10x better being new anyway. Another reason is one time I tried to take that piece off my stock throttle body and I broke the head off the torx screws

 

I looked on year one and found this Accel throttle body accessory kit-Includes IAC motor, coolant cover, clean air cover, and TPS. all that for $259!!!!!!!!!!!!!!!! I just spent $359 on my throttle body...wtf is that just too much? or do I need to buy a used throttle body?

 

come on guys I need to find this piece cheaper somewhere.

 

chepest way, go to ebay, buy a throttle body, it should be on there, and you'll most likely get it for under $50, definetally under $100

Heres one I found for you....hey what can it hurt, offer the guy a price and see if he will end the auction for you.

89Irocz23, email me- I should be able to get it to you cheaper than a dealer.

 

You can get that from the dealer. Don't have the price or part number here. I think it was like 35-50 bucks.

I can get these for the "wholesale" price for anyone else interested.
