To answer your query as to if they are any good etc.. They are a emission restricted head with small circular ports, and I imagine the chamber design to be low quench. I don't think they are particularly great in terms of performance. Even if the valve cover looks cool. :cheeky: Gav (Trying to be Alan T # 2)

Bit clearer

I think this is the NAPS-Z Head found in an early 80's passenger car. It uses an L series bottom end. NAPS stands for Nissan Anit Pollution System or something. Look it up in our forums you should be able to find it. Just found a pic is this it?

I vote keep her Yellow as inside the car like floors etc will always be yellow. I think Yellow is a cool color and I thought you guys all own Z's to feel 18 again anyway. It's a great color really stands out day and night good way to get noticed. I like red and yellow as my first two preferences on a Z then blue and white. Green is a bit further back. Gav

Thank you for posting that anyway helps me as I always forget myself. I have a Unisyn for tuning the airflow now so I will give that a try I've been doing it all by feel so far. I might invest in a colortune kit also but so far so good. Gav,

That's because he edited the photo in paint. You will need to obtain a second set from a wrecker and modify them by cutting the centre section and welding the ends where the grille part was to suit the inside brackets. If that makes sense. FWIW I don't think it's a great modification one tap at the front while parked and you will need a new bonnet and straight non rusted non vented ones are hard to find in Australia. I also think there is too much open space but it's just my opinion and experience from having someone hit my car with the bumper on twice. I am also installing my rear bumper again, to avoid costly $$$ back end problems. Rechroming existing bumpers makes a huge difference. The car looks alot more complete and it's better protected. If you do still go ahead you will want to make a custom grille to fill the lower gap. Gav,

As Beandip says spend the money on a rear end swap. You want a 3.9 or 4.11 if you can get one. That will help you accelerate alot quicker. You could also have a poor ratio gearbox, unfortunately I only know which years of Z in Australia containted the good ratio boxes and diff's. The good gbox here has a 2.9 first gear. The other reason for lag could be fuel starvation, I know a friend who had this problem with his 260z the electric pump would do fine for 1,2 gears but 3rd it starved. I found a 240z flywheel which was lightened and a 240z harmonic balancer(lower front pulley) was a good upgrade on my car , engine revved quicker and felt happier only downside is the engine revs drop alot quicker when you let off the gas. I would spend your money on getting your car in good tune first see how it's going then decide. I wanna put a larger cam in my motor also but I am unsure of how much streetability it will take from my car. Research first before spending your money. FWIW I just bought a set of Toyota 4 Piston calipers in preperation for going faster . Gav,
