i was bored and going to do the tb bypass on my car. i found a digram on shbox but its for a 95 lt1 and it looks slightly different. i was wondering if anyone new exactly how to do it and if theres any differences?

I dont think theres any difference. All you have to do is find the 2 coolant lines, take them off and connect them together.

thats wut i thought. on the passenger side of the tb do u have to take anything off to get to that coolant line? on mine it kinda looked that way.

it would help to take the elbow off of the TB to get to it. find the 2 coolant lines and unplug them. connect them with some 5/16 fuel line. Clamp them down if you want and plug the holes in the TB if you want as well. i bought the kit before i knew about the fuel line

I used some left over fittings I had from a trans cooler kit on mine.

i didnt see a change really, they say the foil does tho, i dont have it.

Yes, the hoses are different, but you do just connect them together, like you said.

does anyone know what the bigger sensor on the lower passenger side of the tb is? doesnt it jus have to do with air flow or what?

93s don't need anything but 2 hose clamps and a double sided barbed fitting. The stock hose that runs to them is long enough to connect to each other AND tie off on the core support! I think the hose ID is 5/16, as mentioned.

That sensor is the IAC (Idle Air Control). And it has to do with idling, so yes airflow.

You can take that whole housing off and cut the coolant passages off if you want. Guy I bought my BBK from did that (with a band saw I presume) and left just the IAC Wish I had thought of that lol

The AS&M I got didnt even have the fittings for it. The barb fittings work perfect on the 93s, thats whats on mine. You can pick them up at your local Home Depot.

thats wut i figured. i was wondering because the sensor was so old it got kinda cracked up when i had to remove it and when i got everything done my car would only start if u gave it gas and stayed running if u revved it up a lil. my fuel pumps went bad recently tho and i figured that it may have totally crapped out or do think that sensor could cause this?

shbox

It's not a sensor. It controls the air needed for idle. If it is broken, you're gonna have problems. Replace it.

how much do you think one would cost?

the airfoil does make a difference btw. a few hp but it makes the intake sound meaner

shbox

IDK, the whole internet is out there for you to check prices.

It's only like $8 I think. And Shbox is right, it's not a sensor perse, but a valve. It does know(sense) it's position though and feeds that back to the computer

Black93_Formula

ok good. and thx guys i appreciate it

i had to replace mine and it was like 60 bucks

Black93_Formula

are u sure we are talking about the same thing? i wouldnt think a little plug in sensor would cost that much. its the bigger, lower one on the passenger side of the tb.
