  1. It's a bit restrictive for that kind of power.
  2. The injector has power on both sides because the ECU pulls one side to ground to energize it. If it's not active, you see voltage on both sides. Sorry not much more insight to your problem.
  3. DAyum, that Z is hot! Is that another 1JZ in the ZX, or a 2JZ?
  4. So it's just a wiring issue - connector doesn't mate? I guess that would suck if they didn't send you the new connectors The injector is a barb type, right? How won't it fit on the rail?
  5. Wouldn't you be cutting the pressure drop in half with two intercoolers in parallel? Have I missed something here? James stated the calculation above - pressure drop is proportional to the square of the flow, the same principle that allows injectors to increase flow only with the square root of the fuel pressure. Doubling the flow (two intercoolers) will drop the restriction by a factor of 4, or 2 squared.
  6. How much timing are you running? Initial and total?
  7. How do you know they are the wrong injectors??
  8. At 45 psi, those suckers are 45lb/hr or 470cc/min. Sounds like potential for 450 safe horsepower. http://www.dune-buggy.com/turbo/injectors.htm
  9. My impression is the squat is good because it is loading the tires. If the car is still spinning bad, maybe it's the tire?
  10. You aren't running any air filters, or cold air intake anymore? It looks great -- how's the tuning going? When are you planning to run it down the strip next?
  11. PVC will not last long. It is not rated for any kind of temperature - it will flow and burst very quickly.
  12. That's a wild looking suck-thru turbo setup you have. What carb and manifold is that? Are you going to run a water/alcohol injection with it? How much boost do you expect to run?
  13. The turbo cars have advance programmed by the ECU - there is zero advance in the distributor, and the splines are different so they cannot be swapped (unless you change the drive gear as well). Turbo dizzys must go with turbo ECUs or standalone ignition computers.
  14. Wow! Bada$$!! Now drop a turbo 350V8 in it!!!
  15. I am also interested in the ACT clutch - which one are you looking at? I looked at their web site and really couldn't make sense of their application data - no 280ZX listed, but several Z31 and Z32 applications showed up - but no data, just "heavy duty". And regarding automatics, Shane switched over to one - just a 280ZXT auto, 3 speed, seems to be working well for him (at least he just broke a driveshaft )
  16. LJ - what are the consequences of putting the fogger in the airstream before your last bend to the throttle body? Ideally, a fogger should do just that, so it should be distributed in the airstream before it hits the back of the manifold. I don't know anything about this stuff, but like all turbo people, I entertain the thought of a small shot to spool, and help cool the intake. Please let us know what you work out and how it works for you.
  17. I agree with Scottie. I found a great deal on my IC. I got a used Spearco for $200, and that included some piping sections. Just get to know your local drag racers
  18. Ahahah, the price of fashion is high!
  19. Pressure drop is caused by restriction. You will cut your pressure drop by 75% with paralleling intercoolers. Most folks make the mistake of plumbing them in series which will double your pressure drop (cooler air, but stupid). It's a good idea; what intercoolers were you thinking of using? The Ford Probe/Mazda 626 ICs might be good candidates, or possibly Audi or Saab 900 intercoolers.
  20. I got a good deal off eBay for a new Bosch pump - the auction expired with no bids, and the fellow let me have it for the opening bid price. It was $160. The same pump came in 77-79 Porsche 911 (and 930 front) . Some 944 turbos and 928s may have the same pump too. They have the high pressure CIS injection system. That same pump came in similar vintage 280 and 450 series Mercedes as well. The Bosch number is 0 580 254 984. Brand new they are $230, best price I could find otherwise. The fuel delivery is almost as constant as you could wish for, at 60 gallons/hour around 60-70 psi.
  21. Your FPR will have no problems with the bigger pump. I would also remove the stock pump and put the MSD in it's place - the stock pump may be limited flow-wise, and could become a restriction. I cannot take credit for the source of the MSD pump, Shane posted that originally. I am getting a Porsche pump for my setup currently, as I have no flow data on the MSD for 70 psi - it seems to be only rated at around 40 psi. Since I may touch upwards of 65 psi fuel pressure, I don't feel like taking chances, hence the HIGH pressure Porsche pump (shutoff pressure is rediculous, something like 150 psi). I would think the MSD will work fine for boost pressures up to 16 psi with a 35 psi base (50 psi).
