Thumper Posted October 25, 2004 Share Posted October 25, 2004 I am working on swapping my 83 280zxt engine and drivetrain over to my 72 240z. I have run into three problems with three solutions but would like your opinions. 1. Fuel tank = I am going to use the 83 zxt tank in the 72 chassis. I think the only problem is that I will have to cut the stock spare tire well and weld a metal plate in its place so that the fuel tank can sit flush. 2. Fuel tank sending unit = I am looking to get an autometer fuel level guage but I need to know what range gauge I should get. I think it is the 70-10 ohm since I've heard the gm 0-90 ohm will read backwards. 3. 370cc svo/merkur injectors = I have a set off 370cc injectors just lying around. Right now i'm limited to 10psi because of no intercooler. Unfortantely I will not be able to get an intercooler for a couple months so i'm stuck at 10psi . So would I see any benefit at my current state of tune by putting these in. I would of course adjust the afm 18 teeth. Mostly I am looking to get rid of the lean running condition after 5k but I do not want to run way too rich under normal driving conditions. Well thanks for your time and input. Ted S.

auxilary Posted October 25, 2004 Share Posted October 25, 2004 some answers: 1. use a 75-76 gas tank for the turbo motor. They are almost a direct bolt into the 240z chassis, since 77 is when the Z cars changed the spare to a space saver and used a different fuel tank. 2. Pete Paraska wrote up a great tidbit about autometer gauges and wiring: http://alteredz.com/gagecalibration.htm 3. I have an NPR small intercooler for sale (cheap). Core measures 20x8.5x2" thick, 2.5" in/out. Caveat is that the end pipes were cut off for a trial fit, but the IC itself is not damaged. I will see if I have pics at home, PM me if interested Quote Link to comment Share on other sites More sharing options...

Thumper Posted October 26, 2004 Author Share Posted October 26, 2004 Well unfortantely I do not have any money even for cheap intercoolers. The reason I am going to try to run the 83 280zxt gas tank is because I have one for free and I do not mind doing some metal work. Plus I like to have a big gas tank for when I like to drive to austin or dallas and back. Thanks for info. Quote Link to comment Share on other sites More sharing options...
