Ok, so I am thinking about getting hondata.

What else will be need for fuel management?

Fuel pump? Injectors? Fuel rail?

Any suggestions? Or is hondata itself suffecient enough?

 

What HP Goals?

 

Enough to land me 12'sec quarter miles daily driven.

Then again it is also going to be a d series, so a lot of boost is going to be needed, with a fully built block.

 

Get an AEM FPR, and then you'll need some huge injectors to fuel enough to get to the 12's. I would guess 550cc may not be enough, so go to 720cc so you can run a lighter duty cycle on them. The upgraded fuel rail is a good idea, and the big fuel pump is a must, get the Walbro GSS342. It is the 255lph for FI.

 

im running a zdyne gold much like a hondata 4B and just have 450 cc's and will hit 12's daily with 255hp pump... id say do the pump and 440-660's and your safe

 

If you have the money redoing your fuel lines would be a good thing to do as well. Usually after around 350whp you want to run larger lines, such as -6an or -8an feed. Some guys on the board have run -10an in the past.

i have seen 450whp on stock lines

 

you can run stock injectors and fuel pump w/ hondata if u would like.

Depending on powergoals the first thing I would upgrade is injectors and fuel pump. You can run alot of power on stock lines, rail, and regulator. I don't see the point of changing it unless you like complicating things and wasting money or until it starts holding you back from making more power.

 

I recommend for the 350whp range 600-700cc injector range, Walboro 255lph intake fuel pump, Hondata s100, GM 3bar map sensor.

Aftermarket fuel lines, rails, fuel pressure regulators are a waste of money. Stock fuel lines are sufficient well past 500whp. The fittings and lines are not a restriction to the overall flow of the fuel unless you are running a smaller injectors with super high fuel pressure or super larger fuel injectors 1000cc+ and maxxing them out. The stock fuel rails has worked well past 600whp. The aftermarket ones are for decoration only. If you run 700cc+ injectors you dont need to turn up your fuel pressure. So the aftermarket FPR's are a waste as well.

 

wow, h-t comes through again!

-saving everything in my notes, thanks again guys!

So do you guys suggest getting the engine management first? I want to do it right the first time, so I dont have to upgrade later..

 

boosted..

Walbro 255lph plus stock fpr = bad juju! If you upgrade the pump you need to upgrade the FPR too.

 

I have been doing it for two years now, with zero problems. The fuel pressure goes up 3-4 psi when you upgrade the fuel pump. When i tune the maps I adjust the base fuel pressure to 42psi and its set.

i try to tell people this all the time

 

walboro 255 HP or regular 255 with hondata?

 

I did upgrade my fuel pump and injectors, I just have to work out the bugs still in my fuel system... i think my Wahlbro might be going bad or something..I'll find out soon enough at the end of the week when i get my injectors tested out... i got everything used from a friend...

My walbro pump did not change my fuel pressures.

The Walbro on my car barely changed my pressure but the Walbros on two of my friends car made them go extremely rich. If nothing else get a fuel pressure gauge so you'll atleast know your pressure.

it shouldn't really matter. W/ hondata you shouldn't see pressures high enough to where you will benefit from the "High Pressure" version. But when I bought mine I got the HP version it works just fine. Survived 150psi from my fmu/inline combination for 3 months too.
