3 quick fuel questions on my Z's

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 :evil: . 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.

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:

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

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.
