ill be running 7-8 psi in my del sol d series. ill be using 12:1 fmu, i can get a gsr fuel pump for a few bucks, will it provide enough fuel for that or no?

 

base fuel pressure 40 psi plus 12 psi multplied by 8 =136 psi of fuel pressure under boost...... I would get some type of pump and ditch the fmu and get some dsm 450s and chrome or uberdata

 

im pretty much broke at this point from buying all else. i ran a 12:1 fmu in my 97 eclipse rs with stock injectors and it ran great, but i never turboed a honda yet.. if i must ill get a walbro 255lph but since the gsr is here i can get it really cheap .but i wanna know if it would work prob be around 200-225 hp total on my setup. also would it help if i rewired it with 8g wire and ground , to a switch right from battery? i did that on my eclipse.

the stock pump flows around 134lph...the power level isnt the problem...I wouldnt trust the pump at those fuel pressures....running a fmu and a stock pump on a honda not going to be cheap in the long run...

 

Would you risk it for the extra $100..

 

guess ill buy a walbro then

Make sure to get an inline pump when using the FMU setup..

an in-line provides more pressure then an in-tank ever will. I know that much . As to why I "think" i heard something about the in-line being more of a sucking fuel pump while the intank is a pusher for fuel? I don't know if that makes sense or is even right, but like I said the in-line provides more pressure for sure

Because the fmu raises the fuel pressure so much..I havent seen an intank pump that can give the needed pressure..Even walbro 255 HP cant handle it..

And I just re-read the op post..You plan on running 8 psi with an 12:1 fmu.? You are crazy..136 psi of fuel pressure..I would think that will put a rough strain on the stock injectors and even the inline fuel pump..
