The 15 Y/O Turbo M42 Build Thread (Now Holley EFI Terminator X Controlled)

Note that Nuke Performance make a rail for them that is supposedly drop in

This is true and I have one. The only issue to resolve is mounting it properly. I am working on some custom brackets to make it work.

[econti]

They don't drop in? That's a pisser. Was thinking of getting one myself

[Dj Buttchug]

It drops in but there is no way to secure the rail to the intake so its just free ballin. Is this how they normally install fuel rails? I feel like a good about of boost will pop the injectors and the rail right out of the intake runners if you don't have it bolted down somehow

[econti]

Yeah nah that's not normal, is a good reason why OEM is bolted down.
That honestly surprises me, I thought Nuke were a good brand

[whodwho]

They don't seem to supply brackets, bmwandhonda had to build brackets for his touring ITB build as well

lots of work to be done

Installed 3 Bar GM map Sensor. Previous settings were at 2.5 Bar which isn't enough. This means the whole tune is off btw. So now I have to re adjust everything.

I like the hard work you put in to it!:up:

[Jaker]

I might have missed it. How much boost are you running? That 2.5bar sensor is good for 22-23lbs of boost.

running 22.

The 2.5 bar actually isn't. Map sensors only operate at about 80% or so of total rated BAR so it would only accurately measure 16-18 psi.

[Jaker]

I've used the Motorola 2.5BAR sensor before and it accurately read to 23psi.

[Dj Buttchug]

possibly so but this one I have is not working correctly so that's why I opted to a higher rated one.

[Dj Buttchug]

New fuel system installed and working well. What a complete bitch it was to mount the Nuke rail. I fabricated 3 different brackets from scratch before finally coming up with a box shape style that worked right.

[Schnitzer318is]

Looking good.

Side note, you remember the pitch/thread size on the studs you're using for the valve cover? That's how BMW should have done it. I had to Helicoil at least half of mine because the PO stripped the threading in the head from over tightening.

[Dj Buttchug]

M8x1.0 I believe. My studs are a little tall but yes totally agree. It is so much easier this way. Better clamping force on the VC as well because the OEM rubber grommets just don't hold up long.
