93anthracite Posted February 9, 2008 Share Posted February 9, 2008 So, I really have searched for this but I'm apparently not putting the right terms in, since I keep just getting info on V8 swaps. Please help me out here. I have a 73 240z sporting an L24 with stock 72 carbs. I am looking to convert from the mechanical fuel pump to an electric one. Can anybody give any recommendations on what brand, pressure, etc that I should go with to get my car back up and running? Part 2: I have an 83 L28ET that I'm slowly preparing to eventually put into this car. In a perfect world, i could get a pump that can work with both of these, but I don't really expect that. So, can I get a recommendation on what pump to get for this application as well, or any mods that could be done to be able to use the same pump for both engines. Any further input would be great if anybody feels like sharing. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted February 9, 2008 Share Posted February 9, 2008 if I remember right EFI needs a lot more pressure and power then carbs do... people who actualy know what they are talking about are the ones you should listen to though Quote Link to comment Share on other sites More sharing options...
CArFAn Posted February 9, 2008 Share Posted February 9, 2008 I was told that 3-5psi or so would be enough pressure for them. And they have mini pumps like this one. http://store.summitracing.com/partdetail.asp?autofilter=1&part=MRG%2D42S&N=700+4294925239+400330+115&autoview=sku Quote Link to comment Share on other sites More sharing options...

ktm Posted February 12, 2008 Share Posted February 12, 2008 Why are you switching pumps? The mechanical pump works just fine. Save yourself the money if you are swapping in an L28ET since you'll have to buy a different pump for the EFI. Quote Link to comment Share on other sites More sharing options...
Derek Posted February 12, 2008 Share Posted February 12, 2008 I used a pump out of a rx7. It was nice and quiet. derek Quote Link to comment Share on other sites More sharing options...
MatMan Posted February 12, 2008 Share Posted February 12, 2008 I second what Derek says, but any generic elect. FP will do. You may want to include an in-line regulator set to no more than 4 PSI as well. Quote Link to comment Share on other sites More sharing options...

I knew I'd read a good recommendation somewhere, just couldn't remember the site name . Thanks! Why are you switching pumps? The mechanical pump works just fine. Save yourself the money if you are swapping in an L28ET since you'll have to buy a different pump for the EFI. Long story short, I'm setting the car up to be able to quickly and efficiently switch between the turbo and carb'ed engine. I'm pulling the tank to clean it (possibly replace with fuel cell) and replacing all of the lines, so I'm setting it up to quickly swap fuel pumps at the time of engine swap. It may sound dumb, but it works well with my plan... Derek, can you give me a little more insight? I'm assuming you're recommending a pump from an old-school carb'd RX7 (SA/FB chassis) to be used for my carb'd application (rather than a later RX-7 for the L28ET)? I'll do a little searching myself, thanks for the info/lead! Quote Link to comment Share on other sites More sharing options...
Derek Posted February 13, 2008 Share Posted February 13, 2008 This is the one I got. http://ww1.autopartauctions.com/a.asp?A=818741&ap=6815&C=11&G=229 I've purchased a fair amount of stuff from this sit and haven't been disappointed.
