ah got it. thanks man.

i scored an awesome deal on some hardware from a thread on m42club. $1200 shipped for a set of dbilas ITBs and an alpha-N 2000 piggyback. at that price i pretty much got a deep discount on the ITBs and scored the computer for free.

got a wild hair up my ass to do the alpha-N yesterday. i needed this nice k&n to go with it- turned out to have a threaded boss with a few different adapters, one of which is perfect for the IAT sensor i needed to use.




as you might imagine throttle response is slightly better. plugs say i'm lean, might either need to go to 21lb injectors or a 3.5bar FPR. i am leaning towards the latter because i've already spent the $160 on a set of 24lb'ers to be used later when i need even more fuel.

still need to clean up the wiring in the glovebox and put the upper cover back on.

wow, i can't wait to see them ITB's in there!

[decay]

me too... but they're the last step in the drivetrain plan. have other ground to cover first. but i had the money and couldn't pass up the deal so now the ITB setup is the incentive i have to execute on everything else.

today's progress:



nice kit from rob with the m42 turbo race car. everything needed included and clear directions.



installed. yes, i know it needs a bath under the hood.

as i mentioned after doing the alpha-N, the car was running a little lean... either it was breathing significantly more without the AFM in the way, or the signal resulting from the alpha-N's meddling wasn't quite rich enough.

so i picked up a set of 24lb/hr injectors from VAC (i bought the wrong kind originally) and swapped those in... apparently that was exactly what the car needed.

i can't give an impression of any of them separately, but:

CAI + Alpha-N + COP + moar fuel = win :D

the car desperately needs shorter gearing (the 4.10S in it now is actually taller than the stock small-case from an m42 vert), a grabbier clutch, and a lightweight flywheel now.

fuck yeah

[1mz]

m42 win! (a rare combination of words)

OMG what a build! Way to go!

That is right purdy, right puuurdy. That is gonna sound sooo good! Sound clips when you get a chance please.

ITBs....sick!

[fiftytakedowns]

Would love to hear about the difference with the ITBS
cams next?

[decay]

still haven't done lighter flywheel yet. definitely a priority now, though.

combined with the alpha-N & new injectors there is definitely more pull up top, and power doesn't fall off after 6K like it used to.

it's still not fast, and having no power steering is a pain at low speeds, but it just seems to come together and all make sense when it's being flogged.

If you're looking for a bit more power, delete your mechanical fan. Made a noticeable difference on the last m42 car I drove. There are also a ton of vacuum and coolant lines underneath the intake mani that can be deleted, though I'm guessing you already did that with your ITB setup.
