Hi, i want to say thanks for those who helped me with the driveshaft decsion. It was indeed the driveshaft and i am very very happy.
Now i have a few more questions...
First off im going to try to get my car inspected soon so i am doing little things, i already changed tha oil, so now im gonna tune it up..
I was wondering what you guys think are the best
-spark plugs
-plug cables
-distributor cap
-distributor rotor
-and what kinda gear oil???

Also, lets say it doesnt pass emissions,I live in Texas, Denton County, part of the Metroplex area. I doubt it will pass..but its worth a shot. But n e ways, I was wondering about my exhaust, it is the original, yea its older than me... I have an 85gsl se and I was getting a RB exhaust, since rotaryperformance is only like an hour away. But about the exhaust i was thinking of getting the hi-flow catback and powerpulse muffler of RB. I was wondering if i would pass emissions here or not..and also i didnt know if this would give me a substantial power gain. Are there any other sugestions on the exhaust? Because i need to pass emissions so it is either the hif-flow cat or the catilytic converter,which is more expensive and less of an hp gain. or so i think. Another thing is Before i changed my drive shaft i would only top out at 90, i havent tried to top out again but do u think that had anything to do with it?? Thanks for any questions awnsered!!!!

 

ngk spark plugs are the best

 

is bosch any good?

 

Nope, unless you drive a German car.

 

I've been running cheap AC's plugs, they work as well as the NGK's I had. They burnup, Auto store replace them for free. The best thing to do is buy an Electronic Ignition. Such as MSD. That solves a lot of problems I would think, check it out. By the way, there about $300 bucks. Someday my toy will have one.

 

thanks for the help so far,
so ok i just called rotaryperformance and i think im going to get the bonez(i know their own brand) catylitic converter and an rb muffler, how would that be?

 

go to NGK's like yesterday. read the thread about using autolites. they destroyed an engine. i have used a bosch cap and rotor without problems. just as easy to buy them from mazdatrix and get mazda parts. i wouls also use NGK wires only. the best it gets for reliable tune-up parts.

 

That would be alright, and should pass emissions, as long as everything else is operating properly, including air pump, ACV, etc.

You'll have a slight hp gain from that setup compared to stock.

 

i have ngk's and it runs beautifully. i had densos in there before and when i changed them the car drove famously.

 

Factory cap and rotor is best. Wires: NGK and RB ones are good.
