  1. Thanks for the info Peter, I have add issues with getting a stable ignition setup and last season fitted the Electromotive XDi programmable ignition which resolved all the issues and delivered more torque, but interestingly no more HP. There are some great features with the XDi like switchable curves and being able to use cranking retard, the current price is less than trying to cobble up your own solution. Cheers
  2. You been Drinkin NZeder, there’s more typo's in your post than in my kids homework. I have considered injection many times but carb's are simple and as the car is driven in the power all the time and tuned to match there wouldn’t be any extra power to be made. Currently we are getting an round 336hp from triple 44 Mikuni’s, if I was looking for economy or wanting to run unleaded fuel then it would be a different story. Cheers

  4. The flywheel weighs 3.5kg and the clutch weighs 3.4kg so almost 7kg all up, I use the rally disks which are thicker and don’t mind being slipped that is until they are hot then it’s very aggressive. I have done 3 seasons on this setup and it has no measureable wear on the disks, the flywheel was CNC’ed from billet 4340 steel and the original ring gear tig welded onto a lip machined in to fingers. The engine is happy to idle around 800 but is easy to stall as there is little momentum, when racing I always make my starts with plenty of rev's up rather than risk a stall.
  5. My flywheel used with a Tilton 7" twin plate setup very light and very usable on the street, the best thing is the pedal is very light unlike many heavy duty setups.

  12. Hi All, I don't have any experience on turbo L28 setups but I did build an stroker for my 240Z last winter and thought I would share what I have learnt and where I am with it now. There are many stories about strokers failing and this is mainly due to the use of pistons from other Nissan motors that really aren't suited. A custom piston with be forged, half the weight and have thin rings which is what you want. I had JE make a set of 87.5mm custom pistons which I attached to a set of highly prepped L24 rods that were bushed to allow the pins to float. All rotating parts must be balanced as they have all come from other engines and must now work together. As the engine is now 3 liter you need to do some serous head work, large exhaust valves and porting to get the gas flow up. The intake side is not as important but still should be cleaned up. To get the valves to open long enough to get the mixture in and out I used a cam with 535 thou lift and adjustable cam gear. I used Mikuni 44's with 39 chokes and a custom 1 3/4 header which is split until it gets to the dif then joins into a single 3" pipe. This combo makes 335hp at the flywheel and 286 at the rear wheels and is very streetable. Off the cam its got torque and when it gets to 3000 it pulls hard to 7000 where its all over. It should rev higher but with 44's I cant get enough air into the engine. One problem I found very early on is the uprated clutches sold don't last long and are to heavy causing nasty harmonics in the engine. I now use a flexplate type setup with a steel button in the middle with a 71/4 twin plate clutch and what a smooth engine it makes. Over the winter I am hoping to find a few more hp by doing more head work and fitting some larger carb's. I have to admit I didn't build the engine myself I worked with an engine builder and my original budjet was 5K and I spent over 10K before I was running. Ricky
