  1. I notice the older distributor has the old timer plastic gear that runs off the cam, where the ZXT (which I currently have) has no such thing.

     

    So my question is to go to an NA setup (the head was shaved so it has more compression than stock), can I use any old distributor and figure out how to get it to work or do I need to camp out until I can find a 280ZX distributor?

  2. I think the couger/T-bird has an IRS setup too

     

    Yes, A arm setup, PITA to swap I bet - HUGE, I would not bother. Perhaps you mean the newer cars though which I know nothing about.

  3. That would still leave me scratching my head some more trying to get everything straight and not having the wideband or the dyno.

     

    You can figure it out on BLMs and using a calculator, but I still suggest the dyno. I payed $100 an hour.

  4. This is a redline, I wouldnt keep it up there very long.

     

    Its got a 4 bolt bottom, it doesn't make power past that because it has a tiny cam, there is nothing wrong with revving it to 7k other than the crappy valve springs and the fact that it wont make power anyway.

     

    I repeat my 2 bolt say 7k RPM with no problems and many of us have done so, with a 3.48" stroke, and all the way up to the 4.25" stroke guys have done so as well. Now I'd prefer shorter stroke of course, but if all you want is around 6k any engine will do virtually if the top end will take it and the bottom end is not ready to die. This isn't the 1940s anymore.

  5. Since I love high reving engines and I am not going after really high HP or Torque marks this seems to be a great candidate.

     

    Ford 302 is light, and has a 3" stroke by default. You can squeeze a 5.4" rod in there, I am not sure about larger being possible but I have read of using 5.7" Chevy rods so something must be possible with the stock stroke. Plus you dont have to give up a bootload of cubes and there is plenty of aftermarket for the Ferd. Nice 3" stroke will keep your piston velocity down, but are you really planning on 10,000 RPM? Its going to cost money to build that either way.

     

    I am looking for an engine that I can pull 5500-6000RPM and maintain for extended distances as it is just plain FUN!

     

    The only thing holding you back is you possibly using an old old old junkyard block. I ran 7k RPM on my 3.48" stroke LT1 on the stock bottom end, with NO problems, 2 bolt caps and all. 6k RPM is NOTHING, and this is exactly why it is ridiculous to go for an ultra short stroke giving up cubes on a street car, there are 3.875" stroke /6" rod cars doing 7k RPM all day long. Alot of these setups are not even running full floating wrist pins.

  6. Ditto, plus you dont have to expect someone else to do a half assed job. I have seen "pro tuners" leave stuff @ WOT with 14.0:1 AF ratios, freaking hack jobs, RIPOFF.

     

    I prefer DIY even if it were to cost more up front, unfortunately LS1 Edit is $550? Tunercat keeps saying any day now when I ask but obviously not out yet.

  7. Most of them likely have little knowledge about their cars (mechanically) and are scared to sound stupid if they say something wrong.

     

    Agreed, I helped push start a Honda in my complex, lowered, body kit, exaust header. After we had it push started he asked me why it sounded the way it did (loud and kinda crappy), he popped the hood and I saw clearly the O2 sensor was not in the header all the way, so before the car got too hot (headers get hot wicked fast) I carefully tried to put the O2 in the bung and he said "oh, its stripped" and I told him well thats your problem right there. Not only will the car not run optimally, but its obviously a fat exaust leak, and he admitted then that he didn't know much about cars, but he still had a couple mods (the lowering job, header and obligatory rice kit).

     

    He also has a sticker on his rear view mirror that says TURBO CLUTCH, whatever that is supposed to imply.

  8. I DONT GET IT. I mean' date=' I sort of understand, but why not tell people how amazing it is, and then kick people's butts.

    I do not street race, but street racing is not just horsepower or traction. It is a mixture of skill, lucky, and the forementioned power and traction. A 12 second car in one drivers hands may run a 14 in another, especially if its a stick shift. There are 13 second Lambo Diablos for instance. So for most of the guys that dont have that many mods on the cars anyway, there is really no reason to brag about what the car has, especially if they talk smack and then lose.

  9. Sweet, your lucky you had a backup, and a cheap one at that. I have seen up to $100 for them :shock:

     

    The diz on the 82-83 handles the timing functions that the ECU needs, I forget the pinout but you can test the values somewhat with a DVM or a regular volt meter. Glad it works though!

  10. You only have + to the injectors, the ECU on the ZXT throws ground to fire the injectors, so an analog meter would probably show this best. Or if you rotate the diz by hand, you can hear the injectors click off, I had them hooked up one at a time so I could test each one.

     

    Originally only two of my injectors were 'clicking' at all. They all fire simultaneously. If you look at the wiring schematic you see green and black, and one of those is a common ground (black I think but I forget, and Nissan did things very backwards of how is done today) all shorted to each other which is tripped at some point.
