Guest Anonymous Posted April 8, 2002 Share Posted April 8, 2002 I have owned several Z's over the past 25 years. My current project is a 74 Fairlady. My main problem is that I could not get the car to run correct with the stock S.U.'s. I converted it to a Holley 390 cfm carb and still no luck. Does anyone know if there is a fuel injection conversion kit available? Thanks Trav Quote Link to comment Share on other sites More sharing options...
pparaska Posted April 8, 2002 Share Posted April 8, 2002 I'm wondering if the Holley Commander 950 TBI setup might bolt right onto a 4 barrel L6 manifold. You might want to hit their site and give them a call. Quote Link to comment Share on other sites More sharing options...
Mikelly Posted April 8, 2002 Share Posted April 8, 2002 From 1987-1994 I drove many Zs that had either the SU or the 4 BBl. intake. When I swapped an 1975 motor into my car, it had the FI harness and everything needed to run fuel injection. We swapped the motor into a 74 260Z, and this motor had flat top pistons, a nice fat cam and a header. Car ran increadibly. No more drama with intermittant good and BAD running carbs, or bad fuel to air mixture. My recommendation is to find a good intake, wiring harness and computer/ sensors and swap it in. Make sure the intake is compatible with your current head configuration. When I DID run the 4 BBl. setup, the only carb that ran well on the motor was a tricked out carter 450CFM that had been jetted DOWN to make it balance better. However, those motors don't flow that large a CFM. and there is the problem with rnning a 4 BBl. setup on the L6 motor. However, NOTHING I did made the car run as well as when it was fuel injected. I won an SCCA regional F/P autocross championship the year AFTER I swapped the FI into the car, due to the consistant performance. The car also ran well as a daily driver after the swap to FI....
