Prospeeder Posted February 14, 2007 Share Posted February 14, 2007 oK im swapping a manifold off another Turbo, NON spider intake car onto mine, well i get it, thinking it would be the same, no.... its got the brake booster inlet on the oposide side, theres some Huge switch that has 3 lines running to it threaded on the back of my original the old one doesnt have, along with some nipple directly in front of the throttle body mine doesnt have, and on the throttle body, on the backside, the new one has 2 and the old one has 3, wich the missing one i traced goes back to one of the lines on that odd switch with the 3 lines. Mines an 86, i have no clue what year this ones from, but newers my guess, what do i do??? i have to get this car running soon. Link to comment Share on other sites More sharing options...
mikeshoup Posted February 14, 2007 Share Posted February 14, 2007 Get another manifold from an 85-86. Sounds like you may have gotten a JDM manifold since the brake booster port is on the opposite side? Why are you replacing the manifold anyways?

Prospeeder Posted February 14, 2007 Author Share Posted February 14, 2007 wow, nice, i got it from Caboobaroo for 25$ because my old one had the thermostat housing was all messed up, the egr valve threads for the pipe were messed up also, so i just was gonna get another manifold. I told it him it was for an 86 Turbo, sheesh, great, i guess ill just deal will it and use my current manifold over again. Link to comment Share on other sites More sharing options...
Frank B Posted February 14, 2007 Share Posted February 14, 2007 That big thing with the three lines sounds like a thermo vacuum switch. If your car doesn't need it, take it off. It may just be screwed into the aluminum and not through into the coolant passage. Add a longer hose for your booster, it can't tell the difference. You may have to play around with the vacuum hoses to get them all on. Use a T connector if you have to. Got any pics?? Link to comment Share on other sites More sharing options...
Prospeeder Posted February 14, 2007 Author Share Posted February 14, 2007 That thing is a thermosensor of some sort, that limits the ammount of vacuum that goes to the distributor, without it, the car will run like crap when its cold, and well when warm.

Frank B Posted February 14, 2007 Share Posted February 14, 2007 But if the car didn't have it to begin with.......... Or did I read it wrong, your old (original) one has it, the new one does not? If so, and the switch is just screwed into the aluminum, then I would tape, zip tie, clamp, or JB weld that sucker to a good spot on the manifold untill you get the right manifold. If there is a blank spot where the missing vacuum nipple(hose barb for the PC), then you know where to drill and tap. Have you traced the other lines on the thermobobthingy? If the missing hose is just unported manifold vacuum, you can get that from another spot on the manifold. Link to comment Share on other sites More sharing options...
[HTi]Johnson Posted February 14, 2007 Share Posted February 14, 2007 As for the nipple being "in front" of the TB, is that closest to the firewall? If so, that is for the automatic tranny. Don't have an auto? PLug it, it also makes a great spot to plumb your blow off valve. Link to comment Share on other sites More sharing options...
