fuel delivery for the sohc turbo

well right now on 210cc injectors my a/f is 11.2. so im thinking for 4-6psi, that the 240s would suffice. like i said i may just go with the 270s if i can find some at the junkyard. the turbo i am using is a 14b. its small for the 3.0 i know, and i have already discussed with brent in detail about how it will not really make any power above 5k rpms. but its what i got for 20$ freshly rebuilt from a buddy of mine, so im gonna put it to use. it will suffice for 4-6psi.

You need more fuel than 240cc man. At the very least go with some 360cc injectors. In my oppinion it is better to have more fuel delivery capability than you will need. That way you should never have problems leaning out under boost. It is always easier to take out fuel than add it if you dont have the correct hardware.

I am using 525cc injectors on my SOHC 20G conversion. Should be lots.

That is what I was hinting at. It would be a waste of time and effort tuning for 240s and wanting to expand eventually. Go bigger and use the controller for what its worth...

And SOHCStealth... Are you planning on doing a writeup on your experience and build pictures? I would definitely be interested. It might even make me want to ditch the 6g74 swap I was planning this summer.

I am planning a full write up with pics. Right now my car is in the shop having the manifolds and downpipe fabbed up. Once i get it back, im gonna start taking some pics. Thanx for your interest, its been a fun ride so far.

ok i here all these fuel managing systems. What is emanage or Maft Pro or SAFC, they have to do with tuning right? dont u need an OBD 2 to use these?

no....

[rubix_cube]

ok, if u dont need OBD2 then exactually how do they work, and how do u know how to program them to tune a car?

like a bunch of the other guys said the 360's would probably be your best bet....if its just you dont want to break the bank on them, just shoot me a pm i have a set that im not using that id certainly let go for cheap

i might do that. ill let you know when i get all the parts and peices and ill see where my budget it i picked up some 270cc injectors today for free. so more than likely i will use those for now. its not much work to change the injectors. the thing im trying to accomplish is to do a budget turbo build to give the other sohc guys some insight as to what they could for the price. as matt has already proven the sohc can take one hell of a beating and keep going.

ok, if u dont need OBD2 then exactually how do they work, and how do u know how to program them to tune a car?

these are ecu piggy backs. the wire into your cars ecu to give you control over the timing and fuel delivery. when you are tuning a car, most often you want to have a leaner mixture of air and fuel for power. but if you go too lean you will melt the internals. at wot with full boost i have been told the ideal a/f mixture is 11.5. but as i have no experience tuning a car, im probably gonna get 3sx to tune my sohc

Where would I get the resistors? I have been searching for a resistor box from a turbo stealth/3000gt and I have a couple from turbo dsm's but dont know if they would work on it or if the one off the turbo S/3 has more wires than a Inline 4 has, anyone know?

Could i use two I4 resistor boxes for the V6? Instead of useing a turbo S/3 resistor box?

Ahem.... I have a resistor box.
