M50NV Turbo Tune Options?

[5Toes]

why? Because it makes the cam timing "hotter"???

I dont think vanos is really needed for boost.. I purposely bought a m50nv car

If you want a broader and higher power band vanos is the way to go.

because you can adjust the cam timing to spool the turbo earlier. The vanos motors have milder cams from the factory which is the only reason they don't produce more power than the NV in stock form. The only downsides to vanos are the larger physical dimensions, extra tuning work, and the vanos seals that need occasional refreshing.

Okay so I have an m20 currently, and I am going turbo. I have the DIYPNP, and it connects to a 55 pin Bosch harness. I might be swapping a m50nv in soon because I got a crazy deal on it. Can I use that harness on the m50? Thanks. Sorry for the thread jack man. Haha

Horrible thread jack, jeez! Check e30tech out, all the turbo guys are over there. But i'm sure you have already. Once you get into the turbo world it'll all make more sense.

Lol, no kidding on the jack!

Yea I just found that today. Should definitely help me out. Might be trying to use a m20 engine harness though...

[GunMetalGrey]

If you come over today bring your m20 harness and we will see if it has the proper connectors, I don't think it will and I don't quite see the point.
Either way, good write up.

You're going to need some explanation there. The crank sensor plugs right in, fuel injectors need light modification, the TPS should plug in or have already been modified, and I think the temp sensors plug in.

I think it might work. He also said this
"It depends on what version of MS you run. If you're on an M20 now or MS2 or earlier, it's batch fire so you only need a crank, tps, coolant temp, and air temp signals + fuel injectors & spark to fire the motor. Also the main & fuel pump relays but that's more or less independent of the motor as is the wideband. If you use the e36 harness, there are a LOT of unused wires."

Im fairly optimistic. Im Using as little of the wiring harness that i can in the first place.
