I wanted to get a 2.9 but if i do upgrade mine i'll probably just get a 2.3 for the fact that i would rather a 2.3 and be able to use the power without spinning like crazy. Sure you can make a shit load more hp with a 2.9, 3.4 or whatever else that's bigger but for a street car the best you can do is run a dr and hope it works. I've seen a lot of high hp cars on the street and spinning makes them look like cars with 200 or so less hp lol. I guess it all depends on what you want to do. My good friend has a 2.3 whipple on his cobra and i don't know anyone who could beat him and i know a bunch of fast cars. High 500's on pump and low to mid 600's on race gas is damn good for a street car.

So I've started getting parts together for my whipple setup. Not alot but its a start. Im thinking about either running the Lethal performance Budget Return Style fuel system (Lethal Performance 99-04 4V Budget Return Style Fuel System [LP-9904BUDGETRETURN-4V] : Lethal Performance, Performance parts for Ford Mustangs) or the stock fuel system with a KB boost a pump . I know the lethal is the better way to go Im just curious are 60lb injectors going to be ok with the return style fuel setup if I plan to go E85 in the future? If not what size injectors should I go with? Thanks!
