Title: E36 Throttle Body?
Post by: E30nate on June 24, 2008, 01:16:23 AM

could i use a e36 throttle body on my e30 intake? they look the same, i just want to be sure before i do it.

no, i was going to do this yesterday. the throttle positioning sensor is 180 degrees the wrong direction, forcing you to put it on upside down or backwards or whatever, basically the tps will hit the intake housing. There is a C-clip on the rotating arm of where the tps goes, and you may be able to rotate the piece back 180, but i didn't try this because i didn't have the time. As well, you may need a tinny bit longer vacuum line to your fpr, as the fpr fitting is straight intsead of having a 90 degree elbo on it.

so other than the tps problem, they should be interchangeable? i will mess with the tps tonight and see if i can rotate it.

i got it apart. you cant flip the arm around. the linkage on the other side is part of the rod, so it has to go in one way.

it holds the shaft in the body. you can pull it out, but the linkage is part of it, so if you flip it around the linkage wouldnt be right.

i wonder if the e30 throttle body is the same? maybe the only difference is the sensor housing?
