auxilary Posted July 10, 2003 Share Posted July 10, 2003 Hey guys, I'm the dumbass who's putting a 13b-re twin turbo motor into my Z. Got the motor last week finally, have an rx7 tranny for it, etc. So, my biggest problem is mounting the beast. My second biggest problem, however, is fuel setup that does not kill my budget, and will not starve the rotary. For those unfamiliar with rotaries, rotary + fuel starvation = boom. Originally I was planning on getting a spare 240z tank boiled out, getting a sump welded on, but I don't know if I want to go that route. The sump may sit too close to the ground for comfort. I'm new to the fuel cell thing, so.... what fuel cell should I use that won't kill my budget? I am looking at a 16 gallon fuel cell, and what should I look for when it comes to specifics? Any preferred brands? The car will be street/track (road course, not drag racing) use. I would LIKE to keep everything under the cost of $500. I know this is a broad range of topics I specified, so please, be gentle Thanks, -alex Quote Link to comment Share on other sites More sharing options...
Tim240z Posted July 10, 2003 Share Posted July 10, 2003 Alex, I think the cheapest route is the Summit 'pro stock' 16 gal cell. Comes with sender etc. You will just need to mount it. I made a metal box in place of the spare tire. Tim Quote Link to comment Share on other sites More sharing options...
spotfitz Posted July 10, 2003 Share Posted July 10, 2003 Why not use a '75-'76 tank? It bolts into the stock location and is already set up for EFI. It doesn't take a rocket scientist to realize that without people trying to develop new ideas we would still be pushing big carts with rock wheels around.

auxilary Posted July 10, 2003 Author Share Posted July 10, 2003 tim: Where is the pickup desired for a track car? drag setup is favored in the rear because of the shifting fuel forces, wouldn't the pick up be desired in the middle? For some reason, I couldn't find the pro-stock cell in the online catalog, only the pro sport. Do you happen to have the part number for that guy? is that it? Also, what's the advantage of plastic cell vs. aluminum? spotfitz: as I've said, how does it hold up to track use and fuel starvation. I was doing a search on fuel cells and efi tanks out of early Z cars, and I caught a few posts saying that with 1/4 tank, people had fuel starvation. I was also talking to randy77t at the Rio Vista meet, and he runs into the same problem at 1/3 to 1/4 tank. The fuel cell already has larger fittings for bigger lines, foam and nice baffles . Another question: do fuel cells normally come with some sort of a sump? I could circumvent the fuel starvation issue with a 1/2 gallon surge tank, but that's about $300 bucks, plus finding a good location to mount it where it won't interfere with the interior spacing. I'm trying to keep the car streetable and practical at the same time Quote Link to comment Share on other sites More sharing options...
Afshin Posted July 10, 2003 Share Posted July 10, 2003 The 13b-re twin turbo should be amazing in the Z, specially for road course set up and all the wonderful twisty roads in the bay area (we're neighboors). i can't wait to hear about or see the final project. I think it will be worth the effort and headaches. Nothing is like a unique set up (as long as it makes good sense such as smooth, high power,light weight and 2 wonderful turbo's).

Tim240z Posted July 10, 2003 Share Posted July 10, 2003 Alex, It's a plastic cell. Just for reference, my Dad's Camaro (trans am series type racing..) uses a cell with rearward dumps, and foam, most road racing cars do. Tim Quote Link to comment Share on other sites More sharing options...
tannji Posted July 29, 2003 Share Posted July 29, 2003 the question about 75-76 fuel tanks interested me... are they made in such a way as to prevent fuel starvation during turns? are the yworth putting in my 240, or is there another mod I can do to address this problem? thanks, tannji Quote Link to comment Share on other sites More sharing options...
Guest shauno_ Posted July 29, 2003 Share Posted July 29, 2003 I don't think you would like the 75 efi tank in your rotary... My 75 would constantly starve around hard left turns with even 3/8th's of a tank. I like to kepp it lower than half for weight reasons but I couldn't stand the heavy loss of power. In your case, it would be catastrophic!!. I would definately go the route of a weld on sump. You will only lose about 2 1/2" of rear clearance ( not that much, unless your parking over curbs ) and you would have the benefit of keeping the stock mounting and fill and sender. It would only cost you 60 bucks for the sump, and maybe a hundred to clean weld and then paint the whole assembly. Then just throw on some fittings and your off. That's exactly what I've done to my turbo L6. I do not need any type of starvation either. Quote Link to comment Share on other sites More sharing options...
