I just pulled my TB off my itr manifold and im curious how to tell if my throttle body is infact a itr tb is there a stamp code on it or...? ty

z6hatchboy

I dont think theres a stamp on it, however i think you can go by the size of its bore in mm.

ekBlackHatch

well im prit sure its 62mm do you by chance know what that is in inches my math is a bit rusty lol

ekBlackHatch

the part # on the side says 88A0 if that means anything and the butterfly says 1JC

z6hatchboy

The c5's are 62mm and the c1's are 60mm so you do have a itr t/b, and that 62mm in standard is 2.48" but the t/b sizes are most commonly in mm(metric).

ekBlackHatch

i know i was just trying to figure out how much 62mm would be in inches its been awhile my math sucks

ekBlackHatch

it looks to be right about 2.5" so im guessing its a 62mm just wanted to make sure ty

z6hatchboy

25mm=1", 62mm/25mm=2.48"

ekBlackHatch

one more question, any advice on removing the intake mani me and a friend pulled all the bolts im sure and the thing wouldnt budge still stuck the only thing holding it is the gasket/glue i think any sort of trick for getting it off that sticky gasket

ekBlackHatch

lol ty

z6hatchboy

Did you take out the bolts from the intake mani support that is under the intake mani? Other than that and the bolts that go on the head studs theres nothing else that holds it on.

ekBlackHatch

ya the bolts on the brace under the im and it wouldnt move it all i must be missing somethin or this is some crazy glue cause i was told it should come off easyer then the tb did

ekBlackHatch

im looking at a pic and i took all the bolts out in the pick, the 10bolts on the flange and the bolts under on the support brace and unplooged all sensors removed fuel rail im stuck

ejoner

Push on the top of the intake manifold were the flat spot is, not too hard but just kinda rock it back and forth, it shouldn't be that stuck on there. Make sure every single nut/bolt is out.

z6hatchboy

If you have all the vac. lines off too thats all there is too it. They're not all the same to get off either, some will be harder than others. One thing that may help is to: While facing the motor get a piece of wood or something soft and put againt the plenum of the i/m and tap back towards the firewall with it. It should come off it'll take a little more than what others have done.

ekBlackHatch

ya a guy at a shop suggested a rubber hammer and tapping ill have to give that a go next time im at that house. Motor is at another place then i am atm ill see if i can in the next day or so. My friend and i pulled prit hard on it witch we probly shouldnt have dont but we got prit frusterated with the pos lol hope i didnt do any damage to the flange

Datphan

you're fine, tap it with a rubber mallet. usually it's on there real tight due to excessive carbon build up.

z6hatchboy

If that i/m is on a itr motor then it must be a fast pos ,lol. Everything should be fine on it though.

ekBlackHatch

lol im just trying to get rid of it i got a performer x im about to put on with some other crap. I was also thinking it was just build up thats got it on so dam tight
