which returnless fuel system do we have?

[satur9]

in tank regulator or pulse modulated fuel pump.i havent seen a fuel pressure transducer, which should be near the fuel rail. so im thinking option 1.

You win the prize....option 1 wins...dont know what you win though..???...and just as a side note...Some of the turbo kits for the mr2 spyder that have the 1zz motor come with a replacement in-tank regulator , which only comes with the kit, and is not sold seperately yet..

thanks. i see these turbo kits with injectors and piggybacks controlling fuel,but no mention of uping fuel flow(not pressure) to the injectors.no matter how big your injectors are if your fuel pump isnt pumping up enough fuel.lean city. i dont know what equivilent hp the stock pump can handle.but i dont want to find out the hard way. looking for options.

in my turbo setup, The shopp I went to designed their own fuel set upfor returnless systems, and it incorperates a fuel pump and ups fuel pressure as well,seems to work great, and If anything , I am cautiously running rich..not lean

Hello I have alot of experience with turbo cars. When you talk about fuel pump people need to know that pressure isn't the magic number. The thing that people need to know is fuel flow @ PSI = hp. In an injected car if you raise the pressure you run rich to a point. Any thing aroung 100 psi = no flow. Just an FYI for you all.
