just picked up a low miles lq4 looking at ordering one of the huron speed v1 truck manifold single turbo kits if they' still available. Looking to make about 600whp on the stock bottom end/heads, m6, 10 bolt on e85 just looking for some help on what I need as far as fuel system is concerned to support that. car is 01 formula so m6 and 10 bolt are stock for the car the lq4 has 60k on it out of a 2007 Silverado classic.

Bigger injectors, a couple of fuel pumps as far as fuel...600 will be easy to hit on E85.

Walbro 485 pump will get you 600whp on a single internal pump. So will some 80 lb injectors.

Ok thank you for the help! Just curious could I run stock lines and rails or would I need to upgrade those also?

Stock ones will do fine. As long as you upgrade injectors and you fuel pump/s. You can reach those numbers easily on 93oct as well.

stock lines and rails are fine. a single 450 would do the job as far as pump. I would go ahead and grab some 1000cc injectors. bigger than you will need....FOR NOW. gotta think about the future, and the nature of the beast being always wanting more. I know where a new BW s480 is for 200 off. if your interested. will get you where you need to be with room to grow. good luck!

Oh and one more thing if you guys don't mind, would the stock fuel pressure regulator also work? I wouldn't think it would but cant find anything about it. Also if it does need to be replaced any suggestions on where/what to get?

I'm still on a stock regulator with dual in-tank pumps from Lonnies performance, stock fuel line, stock fuel rail, 60# injectors. I've been told around the 700hp mark is when I'll have to start to upgrade the rest of the system.

JoeNova

Technically you can use the stock regulator if you have enough injector, but its recommended to upgrade anyway. Boost counteracts your fuel pressure. 58 psi with 20 pounds of boost cuts the pressure differential down to 38 psi. The question is can your injectors keep up at only 38 psi. I would go with the aeromotive 13129. Its cheap and works great.
