  1. Its been a while but any feedback on the performance of your project would be cool. I was interested in the welds on the exhaust manifold itself due to the manifold being cast and all. Did you have any problems with cracking after welding on the manifold or after driveing it around for a while? Did you get the manifold red hot before welding and then gradually cool it over a few hours so the cracking wouldnt happen? wire feed tig or stick weld?

  2. still looking? i have a 74 260z w 280zxt swap running, tokico shocks, tial bov, boost gauge, air/fuel ratio gauge, new head gasket intake/exhaust gasket, water pump gasket, thermo gasket, new water pump, new thermostat, new stering wheel, new voltage reg., new ignition. pm if interested.

  3. 74 260z w 280zxt swap running, no dents, primer black, new parts include- header gasket intake/exhaust gasket machened p90 head, tokico shocks, ignition, battery, door poppers, extra parts. pm if interested

  4. I fired it up for the first time today! So i rented a fuel pressure gauge from auto zone hooked it up and got 60psi. I then replaced those old fuel hoses on the fuel rail and forgot to bleed the pressurized fuel before cutting the hose off, yea fuel sprayed everywhere but was a blessing in disguise when i found the fuel to be flowing the wrong direction DOH! I had the fuel feed line on the drain outlet of the fuel rail and the fuel drain line pressurized from the pump haha! After swapping them around she fired right up! She is backfiring a lot? maybe because i don't have the cat converter and muffler on? I have the air/fuel ratio gauge on and it's reading stoich.

  5. I checked every injector by connecting them to the battery one by one and they all work. The ECU grounds the injectors when it want's them to spray so it's the ECU?

    I had the tack signal wire disconnected because i didn't think that would prevent it from starting but just got done connecting it and still nothing. I don't have one of those little black resistors found under the dash of the L28et for the tack signal wire maybe thats why too?

    I don't know how much fuel pressure i have so im going to get a gauge, also a timeing light to make sure my timeing is good.

    I'm starting to think i'm missing some relay's or wireing somewhere? Any help would help me sleep at night, thanks.

  6. So i got around to puting together my turbo swap into 74 260z, wired it up and have spark air fuel but the injectors arn't spraying fuel. I checked all grounds and am wondering i'f it's my wireing? I have a green light on the ECU but not when canking? Took two pages of notes on the EFI bible got my meter and found the pins to be different on my ECU. Can broken injector clips be the culprit? I have the harness with the CAS in the dizzy and no droping resistors just a fuel relay and EFI relay. Any help will be greatly appriciated thank you in advance.

  7. I started my turbo build the other day and got as far as putting the l28et exhaust manifold and 300zxt turbocharger on the block. I noticed the j pipe does not quite line up with the compressor housing outlet like it should. The outlet seems to be pointing up, more than the stock turbo would.

    My question

    Would it be easier to plumb an intercooler and due away with the j pipe?

    Hunt a used 280zxt turbocharger down and use it instead?

    Or is their another way to make this work?

    Thank you for your time.

  8. Not too long ago i started to notice a small vibration in the rear end of my Z and as i drove it more it got worse untill i thought my rear end was going to fall off!! I took a look under the rear end and found i broke my drive shaft u-joint!!! So check all moveing parts and those old brittle and cracked urathanes too. Well not urathane material but you know what i mean.
