    What year is best?

    So I've decided to pull the trigger on doing as 2.4 in the Rampage. Is there any particular year engine that is a favorite? I already have a spare early style head so I guess I would be leaning toward the 2000 and older engines. The engine will have forged pistons and H beam rods so factory rods aren't part of the equation. Do any cranks have a factory installed reluctor wheel as I was thinking of going Megasquirt with a coil on plug set up.

    If the 2.4s are anything like the 2.0s they'll have the wheel on them since they use a crank sensor.

    Yes.

    I think any year 2.4 will work with megasquirt, you just have to change some settings depending on the year.

    What Mike said. Any of the 2.4s can run with Megasquirt off of the factory crank trigger. For sequential you will also need the the cam sensor. I would recommend a JBPerf board for lowz injectors which would also allow you to do seq. fuel. I used smart LS2 truck coils on mine with MS2 and it worked like a charm.

    Sorry this was the message I meant to quote. What is this JBPerf board you speak of?

    http://www.jbperf.com/p&h_board/v2_0_1.html

    Low impedance injectors are called "peak and hold" and high impedance injectors are called "saturation." Peak and hold injectors peak at a high voltage and then hold at a lower voltage so they open and close quicker with more precession. Some people use resistors to run low z injectors but that's not the proper way to do it. You need the peak & hold driver to do it properly. I bought one so I can run my low z 120 pph injectors sequentially with my Mega Squirt.

    The P&H driver is the silver box, below MS box and above my ignition module.

    Re: What year is best?

    So this box is required to run low impedance injectors with Megasquirt?

    Only if you're running sequentially. If you run batch-fire you don't need the P&H driver.

    Ah. And if we're not concerned too much with emissions, sequential injection really isn't that critical, correct?

    Correct. I wanted to be fancy so I went sequentially. You also need the cam sensor hooked up to run sequential. AZ Shadow put MS on his 8V Omni, ran batch fire injectors but sequential ignition coils.

    Re: What year is best?

    I went sequential because I couldn't get the 1200s to idle well on batch fire. That being said the JBPerf board will run your low Z injectors like they were intended whether is is batch or sequential. I ran my 880s batch fire with the JBPerf board before I switched. The resistor pack just increases the total resistance so the MS board doesn't need to supply as much current.

    I guess I'm late to this party, but just to throw this in: you don't have to frankenstein your starter when you use the older 2.4 blocks mated to a TD trans.

    Re: What year is best?

    So if I'm running 95 lb/hr injectors at 55 psi that makes it essentially a 1100ish cc injector, I'd probably want to run sequential? what kind of advantage does running the LS COP setup get me?

    Not a whole lot, just a coil that doesn't run as hard/fire as often. That is unless you run them waste spark, then they are still firing twice. I went distributor-less because I was getting too much spark blow out with one coil at 25 lbs of boost. I'm running the factory 2.4 coil now with MegaSquirt because I heard you can run them up to about 700 horse power. I'm only going to 500 max but if I decide to go COP later I can.
