i need to be schooled on the vacuum for the fuel pressure regulator.   does it always have vacuum? when does it normally see vacuum? or only boost pressure?   i unplugged the vacuum hose and the pressure didnt changer at all. i hooked the vac hose up to a different vacuum port and the pressure dropped to about 30 PSI.     let the schooling begin!   Thanks for the help.

Hello, today I decided I would buy some new sensors for my 87...so after making the list I went to the car and noticed I dont have a KNOCK SENSOR on my car....my car has been running good the few times I drove it...im still stock...so my question is the following...   do I need a knock sensor on my 87??   oh my car is an 87 with an 89 ecu, distributor and knock box.  

Interesting find from the land of the rising sun. The english is a broken translation but you can mostly understand it. http://garagegsr.gozaru.jp/aboutstarion/GTO/gto.html

Soon I am going to install my electronic boost controller and maf translator. I was wondering if it would matter which I should install first since the maft is like a tuning device and if adding the boost controller second would affect it in anyway? Or do they both not affect each other at all?
