I'm going to be installing my custom turbo in my D16a6 rex soon and here's my checklist of fuel parts:
-12.1 vortech FMU
-airtex inline fuel pump
-B&M fpr

Later I plan to upgrade to 450cc, eliminate the inline and fmu then get an intank 255lph and run the afc hack.

what do you guys think? Will this be sufficient to run 5-7psi?

 

Why don't you just go for the AFC hack the first time? It will save you a lot of trouble.

 

Stock injectors and the 12:1 FMU is not be a smart way to go. Get the 450's and use the AFC hack from the start.

 

im runnin 6 psi with mine with the greddy blue box and i like it. cheap and its all you need. if not that i would stay away from hack and get hondata for sure.

 

I had the vafc and was going to use that for my piggyback system but traded it for the FMIC. As for stock injectors and 12:1 what's so bad about it? This is just to get it up and going and then upgrade it all later, but am I missing anything?

 

Fuel pressures above 100 psi scare me.

no its not bad...i know many people who run 12:1 fmus with 22 lbs of boost at the track and 15 daily..you do the math

315psi of fuel?

 

thats basically all inlinepro runs... and id say they do pretty well, lol

 

Do it right the first time. If you want an inline pump, injectors, computer, etc. Check out my sig! But I definetly recommend getting it all done at once instead of tearing it apart two or more times.

 

agree, but i can't wait and save up for the piggyback and put the turbo on hold. I was just wondering if it's adequate to put on w/ that setup. I can always upgrade later because I'm getting those parts for a real good deal.

 

you may need a missing link or check valves to keep your map sensor from going bonkers.
...i dont think you fuel pump or injectors are good enough, even at 7psi.
...and 12:1 is too much...running it on a GSR i ran really really rich (w/310cc inj's)
...and be carefull the fmu dosent tax your stock pump too much

 

oh yeah check valves for sure. Would I be better off with a 8:1 disc? Will the inline help out the fuel pump or just get the fuel pump instead and cut that headache out now instead of later. I dont' have the money to get the afc right now so I want to get the system going reliable as can be on a tight budget. I"m running an intercooler and low low boost.

 

"Fuel pressures above 100 psi scare me.

Why's that? Is it bad?"

It is bad because:

It puts additional load on the fuel injectors, causing them to heat up more reducing their reliability.

At 35 PSI a stock Honda fuel pump flows enough fuel for about 400 HP. At 75 psi, enough fuel only for 200 HP. At 100 psi, even less.

So, how much risk are you prepared to take? The cheaper solution has a much higher risk of costing you engine damage.

Thanks a lot. Didn't know more pressure then needed was bad.
