I have been searching for hours now and cant find any info. Is it possible to install a 3inch maf and maft into an 86 starion?

Saw a valve next to my turbo with three ports for vacuum lines and a rod going to passenger side of the turbo, I assume this is my waste gate?. Where do the vacuum lines go? there is only one hooked up to mine. What happens if I leave it disconnected?

I'd like to buy a set of polished centercaps for the stock wheels. I searched and it said StarQuestRims was the guy to talk to but he hasn't been online in months. If you have a set sitting around and don't mind selling them, please let me know.   I know it's doubtful that I'll find any polished so I would also be interested in a set of stock centercaps if anyone has extras.   Also, I'm looking for a good set of Starion taillights. I don't mind if they are dirty, I just do not want cracked lense

I find the add and pictures funny for this 240sx for sale. Complete with walmart stick on vents.   http://philadelphia.craigslist.org/cto/3156070569.html
