They are going to beat me up.

"BMW had no wind tunnel when they designed the snow plow on the front of the e24 csi".

My solution is the earlier smaller, read "less plow more slice"

If I was starting off with a clean slate this would be on my M30 list.



NO2 ZEX Nitrous Oxide System $599.95

Bavarian Autosport is proud to introduce the world's first " Smart " Nitrous Oxide System. Using actual bottle pressure to regulate the nitrous to fuel ratio ensures that the mix is always optimized. Never too rich, never too lean! All the major components of our tailor-made kit are contained in the Patented Nitrous Management Unit, which means no unsightly solenoids or wiring cluttering up your engine compartment. This "Dry" system uses the engine's fuel injection system to provide the extra fuel only when the system is activated at wide open throttle. This improves reliability and greatly simplifies installation as no additional fuel lines have to be run. The kit includes 10lb nitrous bottle, Nitrous Management Unit, Jets for 55 hp, 65 hp or 75 hp boost, Nitrous hose, and all required brackets and hardware. Nitrous Oxide sold separately (to be purchased / filled locally).

Here is a MAF from Split Second

The controller is in the glove box, and is indexed to allow me to play with settings and get back to smooth running.



Here is the Ford 65mm MAF and it is made in JAPAN.



If this engine was shiny enough to reflect,
you would see me smiling while taking the pictures.
Cause I really like the output of the MAF.

Six hours, DIY, including the indicator and can switch back to AFM in 2 minutes, Two screw clamps on MAF, two quick electrical connectors and the OE connector is tie wrapped back out of the way.

OE is
3430cc M30
Motronic
DME II
92x86, 8.0:1
185bhp/5400rpm
214lb.ft/4000rpm


I own a dyno so here is the output at the wheels.


HP loss in transmission and differential 25%
So 222 HP at shaft is the result.


I am using the J C. chip also, a 3.71 ratio, with 265 Getrag.

The sweet spot of the m30 is now at 2200rpm where it was at 2800rpm.

That is the point where the rumble of the exhaust resonates in frequency with the intake. On the unmodified it is only seen on the cold mornings when the fuel system adds a little more fuel and the cold air is giving it's all.

I really like it.




My Cartech RRFR installed and test in advance of the M102 12 psi turbo.



I hope to sneak up on a few Stangs and Meros on the Dyno.

Yours should be running a 3.46 to 1 ratio now.
See the tag on the aft plate of your differential.

For $200 to $400 you could get a 3.91 to 1 ratio and be the same gearing as the later M6 e24s.

For $300 to $500 you could get a 4.10 to 1 ratio and be faster than the m6, for 100 meters. "Thas what I'm talkin about".

All differentials from e30-6, e24, e28, and z3 with the correct ratio will fit with the change of aft plate and the swap of output flanges. This is a real deal DIY project for 4 hours.

All my toys have different ratios.
