    Re: 3.0 sohc build

    kmperformance.com has a write up on the emanage piggy back. it goes into detail on high and low impedance stock injectors. id look it up for you but i have to go soon.


    edit: why are you worried about impedence if your going megasquirt?

    Re: 3.0 sohc build

    because I want to use the stock computer until I get megasqurit, and I want to add the injectors when I get them, not just when I get megasquirt.

    Edit: 92+ is High, Before 92 is low. Darn.

    A Greddy e-Manage has the ability to drive 2 auxiliary injectors. So you could use it to provide extra fuel. The cheap but less tunable option is to use an FMU (aka RRG) which increases the fuel pressure in boost faster than 1:1. On my Spirit I am running a 10:1 FMU along with 36# injectors with the base fuel pressure down ~20psi. The Greddy e-Manage fills in some gaps (0-2psi of boost and at higher RPM were the flow of the ported heads diverges from stock heads.)

    Ed,

    Do you still have any of those 3.0L flanges? I'd take a set from you, especially being how much of a help you are.

    last i knew, he dosnt have them

    this is what you need

    ---------- Post added at 02:04 PM ---------- Previous post was at 02:04 PM ----------

    why do you want to add injectors right away? you wont need them until the turbo is on and you cant run the turbo without the megasquirt (or some other way of fueling while in boost)


    your going to run VERY rich while wide open throttle unless you get a fuel pressure regulator that is adjustable and to be honest, thats a waste of money if you plan on going with megasquirt anyways. megasquirt dosnt need the pressure to be lowered.

    Re: 3.0 sohc build

    Alright, I understand. I won't get anything else until I get MegaSquirt, I just am not 100% sure of myself tuning it. I ordered gaskets from RockAuto, just gonna pattern them off that, saw the lab has quite a bit of plate steel laying around, so I should be fine getting the spacers and the flanges cut.

    good to know, didn't know if you were sitting on a set. I posted in his thread, as well as messaged him.

    I understand that, but this isnt a megasquirt kit.

    Re: 3.0 sohc build

    what do people think of the 16G? I know the DSM's used it, specs would be:



    Turbo: Greddy TD05-16G

    Compressor:


    Wheel Trim: 16G60

    Inducer Dia: 1.83"/46.5mm

    Exducer Dia: 2.236/57mm

    Housing: TD05

    CFM: 520@2PR

    Turbine:

    Wheel Trim: TD05H

    Exducer Dia: 1.93"/49mm

    Inducer Dia: 2.20"/56mm

    Flange Style, Housing Size: TD05H6,7,8cm23bolt





    I see the exducer would be what was recommended, and DSM turbos are a dime a dozen.

    Re: 3.0 sohc build

    its to small but somewhat close. I think the 16g was used on the shelby 3.0 prototypes and it had a hard time keeping up at high rpm.

    Re: 3.0 sohc build

    The turbine wheel exducer is too small... You will want something in the 55mm-60mm range.

    Turbo would be on left


    Turbo is one closest to box. For reference, the small one on the right is the mitsu turbo.
