ok so i have hearded a few things about back pressure. one that the z engines like it and the other that the less back pressure the better. i put an after market exhaust, 3inch, on my z with an exchangable catalatic converter so i can use it or just put a pipe that goes to the exhaust. i have been running it with just the pipe but am wondering if puting the cat on would give better performance. any suggestions would be appericiated.

no no its behind the intake and right before the throttle body

yea i got a complete 3.1 stroker droped in. new pistons crank cam everything from intake to exhaust and more air + more fuel = more power in most cases. i got the more fuel just need more air

hey i have a 78 280z and have been looking for an aftermarket mass air set up for my car. there use to be a guy in my town that did it but hes no longer here so, if someone knows where i can find one please let me know. thanks.

thanks man

yea i know of tires but i dont believe those fit on the stock 14 rims

Hey i have a 1978 280z and i have a problem i have been working with my tire guy in my town and we cant find any dot drag tires. we looked at bigger rims but couldnt find the tires to fit it. However we did find full slicks but the class i am in doesnt allow them. So if any one knows of a set up that will fit my car let me know. Thanks.

i did just that i increased the amount of incoming air, and need the extra fuel

yea i know there will need to be a little modification but im just looking for the best performance and esaiest instalation

ok well i looked all over the site i didnt find much on this topic so im going to ask myself. i have a 280z 1978 and im looking for an ADJUSTABLE fuel pressure regulator and ive been looking for one that fits my car. ive seen universal ones but i know about some uneversal parts and a lot dont fit the way they should. haha soo if anyone knows and recamends one let me know please and where to look for it thanks.

hey, i have a 78 280z and i am looking for a new efi system to get the most out of my engine. i have heard of a few with pros and cons of many, but i wanted to get some feed back on what people think of their efi. Thanks

nice that was very helpfull any other helpfull suggestions just send my way haha

people have also recomended megasquirt do u think that would also help?

ooo my bad i was thinking u were talking about ram air yea ofcourse forced induction would work but would that be good for the engine since the engine is high compression and a turbo or supercharger is not
