ZZP Throttle Body Spacer Install

[firebird1]

The part can be found here.
ZZP TB Spacer

It comes with everything you will need for the install except an extra gasket (if you do not want to use the RTV) and you will probably want to pick up a 45mm long m6 bolt to replace the bolt on the top or a m6 nut and use the stud they provide. i didnt have any trouble finding a nut to fit that stud


heres what you get from them:


Obviously the RTV isnt pictured, but is included,
the part number for another gasket is ****_________**** if you decide to go that route.

first thing you want to do is unhook the battery, then unhook all the electrical stuff from the TB. There should be two on the left side.

Now you should be prepared to spill coolant everywhere. make sure you cover this sensor


the floor, and anything else you can. This is the mess i made


Next, there are two nuts on the bottom and a bolt in the top, take them out, and pull the TB off. this is what you should be looking at.


now you have to get the old bottom studs out, i suggest using the two nuts you took off of them and use the "double nut" way to get them out. Dont ask me how to explain it, i just did it; some WD40 will help.

clean off the old gasket if some is stuck to the throttle body, i used a razor to do this.


Time to put the new studs in, the shorter threaded half of the stud goes into the holes, just put them in using one of the nuts to tighten them in.

At this point, i took a rag and cleaned out all the black crap that had accumulated in the front of the TB with a rag, and also on the TB blade

Reassembly is self explainatory. put the gasket on the TB(i used a few drops of the RTV to hold the gasket in place). Its easier to put the TB spacer on the intake first,(using another gasket or the RTV), then put the TB on and tighten the nuts on the bottom and the bolt on the top (or bolt).




all you have to do now is hook everything back up, bleed the air out of the cooling system and refill the little amount you lost when it went everywhere. check frequently to see if any coolant is dripping out of the bottom of the TB/Intake seal, where the collant gets blocked... if it is, be prepared to do this all over again.

Overall, this inexpensive mod is definatly worth it. i can hear my intake whistle again, no obvious power gain, but it definatly keeps the TB cooler.. After an hour drive its still cool to the touch.

I recently did this install as well and I'll add that if you jack up the front of your car or park on an incline you can avoid spilling coolant all over the place (it gets messy!). Also while putting the RTV on it's okay to put too much around the outside of the spacer but NOT around the intake hole itself, you don't want anything blocking your air intake now do you?! Oh, and the directions on the RTV say it takes an hour to dry and 24hrs to cure completely, I didn't drive until the next day just to be safe.
