About 15kg difference between auto and manual Lw prop and flywheel will shed a further 12-14kg depending on type

Have you considered different wheels ? They are momo one piece cast wheels ? - Weight saving to be had there Are you runnng TT Rear end (Subframe, diff, hicas..etc?) ? The cage prob added a further 25-30 'ish kg (its advtanges overshadow its weight though) There are Carbon fibre and Glassfibre replacements available for the Doors, Targas and Tailgate. The UAS 300zx LWB Race car is in the low 1200's if you want some ideas, here's its details : http://www.uniqueautosports.com/motor_sports.htm

Your stretched version started with a 80kg disadvantage :tongue:

Use Fibreglass filler (p40) to fill holes, then smooth with Bodyfiller (P38)

Stock kerb weights are : TT Stock Kerb Weights (Manual) Slicktop - 1510 kg SWB - 1540 kg LWB - 1590 kg NA Stock Kerb Weights (Manual) Slicktop - 1430kg SWB - 1460 kg LWB - 1510 kg Auto is approx 15kg heavier than Manual Weight will differ for UK/Jspec (oil coolers..etc) and depending on spec (elec seats..etc) I have stripped down my slicktop to 1350kg, while retaining Interior and insulation. Thats a good 250kg lighter than the average Zed (or the same as 3 Big blokes) I have weighed everything I have removed/replaced. Rounded up to nearest kg. Front Aircon removed (Pump, Bracket, Radiator, Condenser, pipes, Fan) – 15kg EGR removed – 2kg AIV removed – 3kg Carbon Canister removed – 3kg Lightweight Crank pulley fitted – 4 kg Cruise control removed -1kg Hicas solenoid and piping Removed – 3kg NA Pas Pump and Bracket – 3kg Battery moved to boot – 16kg Lightweight flywheel – 7kg SS Turbo elbows and down pipes – 11kg Fog lights removed – 2kg 70kg loss Centre Lightweight seats fitted – 23kg Lightweight Prop shaft – 7kg 30kg loss Rear Spare wheel removed – 15kg Nissan Tools removed – 2 kg Tailgate weight removed – 2kg Spoiler removed – 7 kg Rear Wiper & Motor removed – 2kg Cargo blind removed – 2kg NA Rear subframe & Diff – 35kg Lightweight Battery fitted in boot + 6kg Rear speakers – 2kg 60kg loss 160kg total loss Wheels, Suspension Components and brakes not weighed yet. An important considering with weigth reduction is to maintain or improve on the stock weight distribution. Stock bonnet is aluminium and very light - lighter than CF bonnets.

The stock boost gauge is not at all accurate, and would certaintly trust an aftermarket gauge far more than the stock one. If you are only getting 7psi and no error codes then It will either be a boost leak or an issue with the stock solenoids, but if you can test the car with another gauge then you should do that.

Zcentre posts the non-brake light version, but not the brake light version. But worse place to purchase - its about twice as much with the VAT and Delivery added. :mad2:

wow. very impressive. Really looking forward to more progress pics and the finished deal. Good luck, going to be a beast.

Car looks great on Track. As for that 350z owner, try not to let him to get to you. From what i can see you were clearly a LOT faster than him and those in front of you. You were taking it steady on that lap, stuck behind a couple of cars and having a bit of a play, all good fun and harmless. Your two current posts on the 350z site are polite, mature and respectful. His responses are egotistic and abusive. Hopefully he might grow a pair if he replies again. Its only a casual track day, some people just take it too seriously.

Auto Camshafts - 240 degree intake cams & 248 degree exhaust cams Manual Camshafts - 248 degree intake cams & 248 degree exhaust cams Auto Turbos - A/R = 0.54 Manual Turbos - A/R = 0.63 "Official" Figures for the Jap/UK spec : 276 for Manual 263 for Auto (300/280 is for the U.S Market) They key to searching is to use as little words as possible, and only words that will definatly be in the context of your search. The search goes through all text in a post, not just the title.

Damn. Glad your ok. From the damage you've described its very likely it will be an insurance write off. Cheaper and simpler just to pay out, than to pay for repairs and hire car costs.

lol damn. I just posted this too :rofl:

Murt pointed this out to me on Amazon http://www.amazon.co.uk/Pearls-2-I-Nissan-300ZX/dp/B004FXGRFU/ref=sr_1_14?ie=UTF8&qid=1305677953&sr=8-14 :confused: .....and a quick youtube search..... WTF !?!?!?

urgh IE ! Use Firefox or Chrome.

While I'd normally reccomend MJP for all OEM parts, the perspex panel is perhaps one exception. They are very fragile and often get broken in delivery. The best option is actually your local Nissan dealer so you can collect it yourself. Its about 40-50 pounds for the non-brake light version. Just give them the Part number 26590-49P00

There is plenty of proof out there. If I had a proper internet connecting now I would search for some brake stopping disance Comparison tests.

The pressure is in the system is the same, but the amount of torque applied for that pressure is greater with the BBK. By torque I mean the braking force that decelerates the wheels - the clamping force of the caliper on the disc.

I spend all day having to read about, write about and calculate this sort of stuff as a Motorsport engineering undergraduate, but It does'nt really matter if nobody believes the theory behind it.... .....its all been tested, proven and documented, both in the public domain, from Automotive Magazine and media tests and withinin Engineering and Motorsport technical papers and publications. There are many advantages to larger brake kits, but the facts are that Big brake kits do not really reduce min stopping distance (at road legal speeds at least), and they can interfere with ABS system performance when the Braking torque and volume characteristics do not match the stock system.

Good explanation of the ABS system, but let me explain the problem..... The ABS sensors measure wheel speed only, at set time intervals of every few milliseconds and with this it knows the wheel deceleration. It does not measure measure vehicle velocity, vehicle deceleration or line Pressures. It does'nt just release pressure to the caliper, it releases pressures for a certain amount of time in order to maintain an approproate pressure to bring wheel deceleration back to a correct level. How much pressure, and therefore how much time to open/close is calculated/programmed according to the stock brake pressure-torque characteristics. And thats the problem, a vehicle running larger brakes does not have the same pressure-torque characteristics as the stock system, which the ABS is programmed for. Any given line pressure in a stock brake system produces a different level of torque than the same line pressure in a larger brake kit. And subsequently 10milliseconds of releasing line pressure does not result in the same wheel deceleration/reaceleration with a larger brake system that has higher braking torques and piston volumes. The problems with Big Brake kits and stock ABS systems have been experienced by many and is well known about.

700 thing would of been some sort of major search engine robot spam session

Had unfortunate dealings with Ryan and old Ztech, never met Chris or had any dealings with him......have to say though.....its amazing how similar they both seem !!! Has anyone seen them both in the same room at the same time !? :eek: :x:

HIDS - One of the best mods you can do to any Z. Cheap, easy to fit, and make a massive difference.

check the pad retaining pins and metal spring plate is in place in the caliper properly.

can understand why you wouldn't want to drive it, but why would you want to look at it :tongue::lol:

Braking performance will certainly be improved - forces generated are much greater - the car brakes harder with less brake pedal effort. But have you actually compared minimum stopping distance ? - Providing these sport packs/AMG Range options dont include Suspension and wheel size changes...which Im sure they do, and would affect stopping distance. Im sure the reason for manufacturers fitting bigger brakes is because its expected that the sports models are going to be driven a lot harder than regular models and perhaps at higher speeds. There are lots of benefits to bigger brakes but Im only talking about min stopping distance at road legal speeds here. The other reason I bet is - marketing. Customers expect big flashy brakes if they are buying a more expensive sports model. As for ABS - ABS systems takes snapshot wheel speed sensor measurements in milliseconds of all wheels, and control what to do with this information with a set algorythm. The larger braking forces generated confuse the system which shuts of line pressure for set time periods based on the stock pressure-torque characteristics. The result is that its no longer capable of holding the tyre consistently at its peak traction. Although this is in regards to much larger systems than the GTR setup, which appears to be a decent match for the stock Brake master cylinder and abs.
