City Hunter Posted August 24, 2008 Report Share Posted August 24, 2008 So, my 240z was swapped to a 75 or 76 l28 duel injection setup with the n42 head back in 82. Well, i have no idea if the fi is still good as it was pratially taken apart when I got it. I also have a set of 44mm su carbs with e88 manifolds. The question is, whats going to net me better power. I have no idea howb good these su carbs are. Drivatebility is there any benefit to the fuel injection other than starting? I'm usually a die hard fi guy, but I may consider rocking the su's Quote Link to comment
ggzilla Posted August 25, 2008 Report Share Posted August 25, 2008 The EFI makes more power than the twin factory Hitachis... I doubt if SUs would be any better. Quote Link to comment
slodat Posted August 25, 2008 Report Share Posted August 25, 2008 My vote is the EFI. You won't regret getting the EFI working. Quote Link to comment
City Hunter Posted August 25, 2008 Author Report Share Posted August 25, 2008 really, I was under the impression the carbs would make more. I guess I will just toss that shit back on, after I make my hose clamp injetor feed lines :rolleyes: Quote Link to comment
ggzilla Posted August 25, 2008 Report Share Posted August 25, 2008 Japan-spec Z shows the power difference: L26 Twin-carb: 140 PS, minimal emission controls L26 EFI (USA): 140 HP, lots of emission controls Quote Link to comment
City Hunter Posted August 25, 2008 Author Report Share Posted August 25, 2008 I dont really have any emissions on this fi setup, no egr stuff, no cats, just deburred headers dual 3 into 1 with no hpipe into 2 cherry bomb looking things out to 2 vert pipes. I'm curious to what kind of power it might make, and wondering if it has a cam. Also rocking some allison electronic ignition. Quote Link to comment

ggzilla Posted August 25, 2008 Report Share Posted August 25, 2008 How much power did the 240Z make with the factory twin Hitachi carburetors? Quote Link to comment
Bleach Posted August 25, 2008 Report Share Posted August 25, 2008 The way HP was measured changed in 1979. so comparing the early ID tags 240Z 150hp 260Z 162hp ? 280Z 170hp same engine rated in 1979 at 135hp Then 1981 145hp / turbo 180hp the FI will have way more torque than the carbureted engines. but also, the displacement was going up in the 70's. Even if you get 170 flywheel hp out of carbs, it will have less torque and less economy. Quote Link to comment
