so ive been researching ect, so pease dont flame me right away. ive been collecting all the info i can on putting a t2 motor in my sa.

me a my buddy put a efi turbo 2.3l in a mustang that had a carbed 5.0. doing so we learned that you can not use the same gas tank. can you guys tell me what gas tank i should use. or is this just a stupid for deal.

 

the main reason iam asking is cause most t2 swaps ive seen are done with fb's not sa's so iam not sure the same tanks will work

 

You have 2 basic options, plumb what you have with a carb pump, a surge tank and an FI pump, or mod the tank to accept a 2nd gen TII intank pump along with the sump cup from a 2nd gen tank.

 

I would go with the modified tank (with the 2nd gen sump cup) and the in tank walbro. Scott and Sam modified my tank for me, and I am going to be running dual walbro 255lph pumps in tank.

Personally I really enjoy a simple setup (single fuel pump), that way you could diagnose it easier in the long run if you have any troubles. This setup is going to be a bit more money, but it is very simple and functions well after the initial investment.

 

is there any welding that is needed in these mods to the gas tanks, i really really dont like welding on gas tanks. i have seen frist person a gas tank blow up that was filled with sand.

 

I think most of us weld it, but you can do it without welding like renns did in this thread: https://www.rx7club.com/1st-generation-specific-1979-1985-18/efi-prepping-1st-gen-577867/
Either way will work. It's a nice setup when its all done, quiet as hell and you have all the same available options as FC owners as far as aftermarket pumps etc.

 

Sand is bad. By adding sand you have made it into a mini claymore bomb. There are 3 options for welding on gas tanks

1)Fill with water. and i meen FILL. There cant be any air pockets, which sand still has.

2)Use exaust from a running vehicle pumped into the gas tank. No O2 no boooom.

3)And Last and my favoret. Most people freak out when i show them this, and they usually go running for the hills. Ready? .....Follow step 1 only this time use the gasoline as a filler instead of water. Yes thats right i said GAS. Gasoline as a liquid wont ignite untill extreamly high temp. Its the Gas vapors that ignite not the Liquid, which is why it is so important to FILL the tank up all the way to the cap, otherwise

BY the way this applys to all types of automotive fuel types, besides propane.

 

i new all of those tips on welding a gas tank and i new about filling it with gas too. its just that i rember when i was 17 and in high school one of the teachers had one of his friends come in and tlak to us about welding on gas tanks . this guys was 75 been moding gas tanks for bikes for close to 50 years. then one day one blew up on him lost some finger and half his face was burnt. after talking and seeing this guy it put fear into me when it comes to welding on or near gas tanks.


thanks for not flaming me for asking this. well not i need to find a how to for moding a 2nd gen omp to fit a frist gen cover ect. thank you again. if any of you guys are willing to give me tips ect please hit me up.

iam the typ of person that will ask 1000 dumb question so i dont make 1 dumb mistake.


(i went to a trade school, i took metal fab welding/ fab ect one week school one week in shop ect.)

 

with all that was said are you all saying that the 1st gen GSLSE tank isnt any good?

 

How about a fuel cell in the back? Thats what im going to be running once I do the T2 swap.....going to re-do all the fuel lines, put a cell in the back and probably use an aeromotive in-line fuel pump.
