  1. I am not planning to do any "proper" racing - all I am interested in is just track days so roll cages arent required officially and there will be plenty of more modern cars on the track at the same time. Also I have read somewhere that a cage doesnt stiffen up the body by much - something like only 15% on average which seems quite unrealistic in my opinion plus there are a lot of variables involved - how effective is a rollcage in your opinion? The reason I am intersted in stock chassis is beacuse atm I do not have the funds to get a proper rollcage - still have plenty of other parts to upgrade and fix first. So in your opinion S30 with 300lb springs will be quite competetive? And whats ARB? And how did your fj20 260 compare to sr20 silvias etc. on the racetrack?
  2. Have been reading a fair bit on springs selection for 240Z and have heard that you can't put really hard springs (more than 5-6 kg/mm spring rates) on these cars because then the chassis itself will start twisting - hence my question - will the preformance of 240Z on a racetrack suffer much from relatively low spring rates and a relatively non-rigid body? Would a well setup 240 with basic suspension mods such as coilovers with say 5kg springs and matched shocks etc. be comepetetive (cornering wise) against cars such as a well setup AW11 MR2 or 240SX with coilovers with higher or same spring rates? How did your cars go against more modern cars on the racetracks?
  3. Thanks for quick reply. So what would that be at the wheels - has anyone actually dynoed their cars with these engines - got any dyno graphs? Any torque figures and the rpms those figures can be expected at?
  4. Been trying to find power figure for F54 L28 with dished pistons and N42 cylinder head running 240Z SUs and Extractors with full exhaust - what sort of power/torque atw can be expected? If noone knows of power/torque for this combination - how much in general can an L28 produce stock or with mild mods at the wheels?
  5. As the topic states - whats the power/torque required?
  6. ouch... sorry to hear about the paint... hope the other side works out better.
  7. Got a P53 with a random single carb (think its a complete 240K setup) on my project car and since I have no manifold/carb on my new daily driver I was wondering if there is any point in swapping P53 onto daily car or should I just find myself an E88+2xSUs? Any help with P53 knowledge/usability will be greatly appreciated as I have no clue about this set up.
  8. Got a picture with the vents installed? And thanks a lot for you pictures Owen - I was very eager to see the rest of the car in more detail but could hardly find any photos on the net - I am even more amazed with the car now - I am scared to even think the time you spent on everything to get it to the level where its at now - TOP JOB!!! And I am definitely interested in the set of vents as I have told you earlier. Cheers.

  10. Which one is your favourite? Post pics!
  11. How much power and torque can I approximately have at the motor before I start twisting my chasiss past its elastic limit?
  12. Thanks for your help guys. The car mentioned above was one of the reasons I have wanted to put such big wheels on a Z - they really do look great in my opinion Does anyone know what wheel are they and what offset is he running? I tried emailing him but didnt get an answer.
  13. Its an 1972 240Z. And I am already quite familiar with the concept of unsprung weight. To counter the acceleration loss I am planning to run a higher diff ratio with a 280ZX 5 speed box... dont quite see how it will affect my bracking by any significant amount (the brakes are being upgraded anyways)... and dont really care about milliage; but thatnk you for your concern anyway. Should have also prob mentioned that the car will be running this coilover setup: http://www.cosmoracing.com/productinfo.asp?cid=259&pid=1347
