Newbie Questions

Just picked up an 88 , auto, ......couple of questions - has anyone had problems with a fuel cover release lever that doesn't work? how do you correct it? so far I've been going in behind the spare and simply pulling the cable from there.....and by the way - what fuel is best? Full Premium (91) or does anyone use anything less? And one more thing...oops, 4 more...where do I get 1. Front end license plate bracket or holder 2. T-top headliners for those times when I dont want sun or moonlight 3. what are the specs for my rear and front stock wheels? (thinking about replacing them) 4. car seems a wee bit sluggish...any suggestions?

Yeah I got the same problem with my fuel filler cover. I do the same thing. Most of the time the cable breaks next to the handle.

#2 that will cost you a pretty penny and #4 it's sluggish because it's an auto I have the same problem with my other Z get a manual.

Hey (85 fairlady), thanks for that feedback . . . those are really badass oil pressure and voltage dials....where can I get those? And how expensive?

S'up SKD_Tech.........tell me something, did your Z perform any better with the K&N Intake modification? Will that help my somewhat sluggish performance? I mean I know it's no manual but I want to get the most out of my automatic .... before I trade it in and go for something manual.

I could tell a little but it's not as much as they claim. If you want some good performance get rid of the stock fan and get electric. That's the easiest thing that'll get you HP

If your car is not a turbo, use 87 octane
If your car is a turbo with stock boost, raise the boost and run 91
If you don't raise the boost, run 87 and you are stupid for not running 12 psi.

Intake, 240SX throttle body, 2.5 inch exhaust, electric fan, and drop some weight.

Can anyone take a pic on where the vaccum line is for the wastegate? For the life of me I can't find it and I even got the AC compressor off!

It's kind of below the turbo. There are two vacuum lines coming from the front side of the turbo outlet that go through a y into one line, and into the wastegate actuator. it's a bitch to get to. take off the inlet elbow that goes from the MAF sensor to the turbo inlet. You need to do this to see anything. The wastegate has a rod that goes from the compressor housing to the turbine housing. it's in between the turbo and the inner fender, and it's bolted to the turbo. It should be a copper color, unless it is dirty. The best way to mount the boost controller (manual boost controller) is to put it under the car, so to tune it, you have to lay beside the driver's side front tire and reach under the car toward the turbo to turn the nob. the easiest way is to put a long vacuum line on the wastegate actuator, and run it up toward the top of the strut tower, so it's easier to tune. Having a shorter vacuum line will decrease boost creep, but mount it wherever you feel most comfortable.

yeah I'd rather have it low and out of sight to keep the sleeper/beater look. Alright man. Where can I order these boost controllers and how much boost can I run without an intercooler 12?
