Okay so I need you guys opinions. I'm thinking about buying CJM's twin pump 5/16 & 3/8 340/450 fuel pump for my s2k. Eventually I'm going for E85 but not any time soon, I daily by s2k (93 has) as of now and I want my turbo build to be flawless after I buy my next car so I can continue turning it into a circuit track car. Is this over kill or could I do it? How would my fuel economy be? End goal is well over 600+ WHP. What would you all recommend for injectors to go with this?

I’ve heard that a single Walbro 450 can get you to 7-800whp, so don’t know if you really need dual pumps. I’d go with either id1700x or id2000x for the injectors. If you are on a returnless system you’ll need to convert to a return one also.

Okay bet. So would it completely pointless if I ran dual pump or would it only be unnecessary? I have a return adapter already and I was looking more towards the id2000x

I mean, it probably wouldn’t be needed unless you want to try and push 1,000hp, but you could always do it if you want. IMO it’s just more mechanical stuff to potentially break, so I went with 1 450 pump. I’ve also heard of ppl having issues with the FB dual pump hanger leaking, but I’ve never heard anything positive or negative about that one.

Okay i appreciate it. I'm going to purchase it from sos instead since it's cheaper for a single 450.

Nice. SOS has a mounting bracket for the 450 pump that works great so you don’t have to use zip ties to hold it to the carrier. Lol
