  1. Cool glad you all found some decals that you needed. I know I have been looking for the 20th anniversary decals for months and just lucked up on that site.

  2. you need some silver indicator bulbs Lee.

     

    Yeah I know I have been planning on upgrading to the 06 headlights, so been holding off on that.

     

    Thanks for all the compliments guys I really do appreciate it. You have a really awesome site here. Try to keep the Minel in check if you can :thumbs:

  3. Thanks for the compliments, I appreciate it, the bonnet is the stock hood cut (with fine black mesh in the vents) like the Nismo RS Concept Z.

  4. Just a review on the Wilwood, a friend has em on his TT Z , and he says they are junk. Endless, Stop-Tech, Rotora, AP Racing all have had good reviews in the US. From what I gather after talking with Stop Tech, 4 POT brakes are sufficent for the Z, the size of the rotor is really what counts for heat reduction. 355 Rotors with 4 Pot Calipers should be a great set up. :thumbs:

  5. thanks for that, I will look at the HKS system based on your personal recommendations

     

    One thing I have noticed is some get bad reports for the clattery noise they make, I presume with a self contained cooling/lube system this isnt the case on HKS (as you said, just need clarification)

     

    Also I'm happy with stock exhaust, would the system work ok? I'm not wanting to change too much at first so basically stick the HKS on, does it really require an intercooler or as its good at keeping a low temp is the intercooler really not needed?

     

    The HKS unit is very quiet and does not clatter, if you keep the car stock, dont even change the thermostat, the HKS does not need tuning. You can just plug in the pre tuned F-Con and go.

  6. This has been a topic of much heated debate in the US. First of all I want to say that the Vortech is a very nice supercharger kit and this post is meant in no way to say its a bad FI solution for your Z. That being said before I went FI on my Z I did alot of research and came to the conclusion that if you were not willing to spend the extra money to build the engine, due to the weak point of the connecting rod bolts, turbo was not a reliable choice for the Z. Then I started researching superchargers, the ATI Procharger had timing issues and had popped alot of engines, the Vortech was nice but I was not pleased with where the powerband was in the RPM band. The stillen is a very nice supercharger and has linear power but the hood was not something I was willing to put on my car. IMHO its ugly. So I had just about given up when I came across the HKS Supercharger, the HP peaks much sooner in the RPM band and the TQ was very nice. Rotrex makes the supercharger unit which is used on BMW. So that was the one I went with, and could not be more pleased. I have had it on for almost 2 years, no lights, no problems, it has been a great supercharger. I have added a couple of modifications to mine for a little more power, I have the Nismo Cams, AAM Plenum Spacer, RC 440cc injectors, to do away with the extra injectors that comes with the HKS Kit, doing this allows for more precise fuel control. The car is tuned with HKS F-Con along with the HKS Navigator, to help her breathe better I put the Nismo Exhaust on. The great thing about the HKS is that it is a self contained system, it has its own oiling system with a oil cooler, it does not run off of engine oil, no tapping the oil pan. As a result the Supercharger stays very cool , and no power loss due to heat soak. On to the power I have 335 RWHP 325TQ here are some calculations that were done by a 350Z tech member using dyno sheets from a Vortech and a HKS supercharger

    In a comparison between a 401whp Vortech and a 329whp HKS SC.

     

    Calculations are under the curve, or "mean" hp/torque. Basically the avg. hp and torque each unit makes under Peak power.

     

    The Vortech avg. HP = 268

    The HKS avg. HP = 264

     

    The Vortech avg. Torque = 286

    The HKS avg. Torque = 297

     

    What does this mean? The HKS SC ... Makes more torque under the curve and is down on PEAK power by 72whp...

     

    Short answer. HKS makes more useable power. And does so more efficiently. The power curve is better

     

    That being said, in real life, I have raced APS single turbo car, and a Vortech supercharged car. The Vortech I can get such a big jump on from the take off it gets ugly. The APS was about 3 car lenths up to about 80 the slowly up to 140 he caught up I had him by a fender at 140. This is not to say that there are not Vortech cars and APS Single cars that would beat me. But the initial power on the HKS is incredible and I could not be more pleased. Again this was in no way to say HKS is better than any other FI kit, its just to be informative. :thumbs:
