Not so much a question as an observation from other members I was wanting. I have a 1973 240Z. We are putting an '81 L28 into her, running dual Weber DGV carbs. Now from talking with a multitude of people on the internet I have come to understand the the '73 originally had two, count them, two fuel pumps; a muchanical and a manual. This was due to the flat-top Hitachi carbs that were prone to vapor lock. My new engine uses the P79 head, therefore it does not have the eccentric for the manual fuel pump on either the head housing or the cam itself. I have therefore decised that since the '73 has a backup electric fuel pump back by the tank to use it's wiring and mount a nice aftermarket pump there. My choice was a Carter. It has 6.5psi and puts out a mild 72 gallons per hour. This will (hopefully) keep the bowels from drying up in my carbs. But now I have to fix the psi problem I created. So I got a dial-type fuel pressure regualtor and a Moroso fuel pressure guage to mount in front of the carbs to set the psi and monitor it. I have been told with my Webers I needs around 4 - 4.5 psi. Is this correct? Do any of you see any problems with this or have any suggestions? ------------------ "Go into emptiness, strike voids, bypass his defences; hit him where he does not expect you" -Lao Tzu

I, has my friends say, have the Z bug. I've had eight. Unfortunatly I know less about them than I'd like. My latest is a 1973 240z. It was purchased and then drove over 100 miles home. It ran little after that. After messing with it over and over again the decision was made to put a new engine in it. I have a wrecked 1981 280ZX in my driveway. So I pulled the L28, with P79 heads on it and cleaned off all the fuel injection crap. My plan is to rebuild it with the carbs on my 240z. Now the gentleman I bought the 240z from put double Webers on it. As these carbs seem to be in good working order I am going to reuse them. In addition I want to replace the 240z 4-speed with the 280ZX 5-speed, replace the 240z R180 rear end with the 280ZX R200 rear end, steal the rear ZX disc brakes. Here is my question. Have you any opinion to what I am doing? Any tips? Suggestions? Help? Am I missing anything? Is this going to work. Most of my planning thus far has been from notes and vague references on the interent, so I really hope this goes well and does not cost a fortune.
