M54. Let the foolishness begin.

M54 injectors/injector flow

While I had the cams out I took the opportunity to send my injectors off to Witchhunter Performance. They had 100,000 miles on them and although I run a bottle of Techron through the tank occasionally, I had no idea how dirty they were. Mailed them on Monday, back on Friday.

I also found very little data on how much they flow, I have seen everything from 21 to 30.5 lbs. 320cc, etc.

Result: They were acceptably clean to start and they flow 24 lbs, best that I can tell.


These are Siemens DEKA injectors.
(BMW part#: 13537546245 Siemens part#: 1439800).

For reference, M50/S50 are 17lbs and M52/S52 are 21.5lbs.

Correct me if I'm wrong on any of this data!

ZHP cams are installed.

Ran into a small snag when THREE of the cam tray studs didn't hold torque on re-installation, they each had a shuffle pin associated with it. I had to pull the cams back out and helicoil. No bigee.

I'm getting really good at installing cams and timing the dual VANOS!

Car pulls noticeably harder after 4000rpm. For $299 these are a bargain.

dyno sometime soon.

That's a beyond awesome deal. I still can't believe that it's only 299 for a set of cams, valve cover gasket, and spark plug gaskets.:p

Just ran across this thread. Awesome work being done. With all the effort put into the custom tuning and modifying of all the sensors, wouldn't it have been easier to get the EWS to work and keep the dual vanos rather than going OBDI? I am doing my own M52TUB28 swap and keeping the OBDII and EWS systems. Even giving it traction control.

Glad to hear there are others out there working with the newer motors!
Good luck

I looked at it the other way, it was easier for me to keep dual VANOS by going OBD1 and not dealing with EWS. (plus it's easier to tune now and I don't worry about emissions lights, etc.)

All sensors are stock sensors, except I've added OBD1 knock sensors, the e30 cluster temp sensor and an M44 crank sensor.

Yeah I was thinking such a mild cam wouldn't be worth it, but for $300 there's no reason not to.

Very interested to see the results; Steve, I really like that you're spending the time and effort to document all of these results step-by-step and share the dynos--it makes for a much more interesting read (and given what you've done so far, that says a lot). Hopefully I'll catch you at the next picnic, last time I was super bummed I didn't get a chance to take the M54 E30 for a spin! :(

Nice! That's a heck of a deal for cams. This is making we want an m54 so bad!!

[hoveringuy]

After the last several dynos the motor just seems tapped-out and won't gain more with tuning. So, until I find an S54 I have cams on order.

Stock M54 cams are intake 240/9.7 exhaust 244/9.0
ZHP cams are 248/10.0 248/10.0

They are supposed to be good for 10hp/8tq. With my mods I'm hoping for closer to 15.

Only $299 for the whole kit at ECS tuning.

Thanks Steve, yeah all the power is at the top end, but that's where it will live as a race car, it's got a M3 6 speed box so should be good.

[hoveringuy]

You're power curve looks much different without VANOS and DISA, but 250 torque... holly sh!t.

Great job!

One of the runs

[kariotahi]

Did the dyno today, came out with 218 rwhp and 250 ft lb of torque, very happy.

WOW you are crazy. sick stuff :up:

Steve, thanks for all your help. This is just to let you know it's all up and running now.
I've fitted a M54B30 into an E30 dedicated race and track car. Not out of the ordinary, except that the twin vanos has been removed and the cams locked, it's running all M50 bits other than the head and block, including the M50 front crank wheel and M50 crank sensor. I've used the Zionville front thermo housing adaptor and blocked the heater hose outlet on the head. Have used the M50 intake and fitted and locktited set screws into the extra air inlet holes the m54 has at the intake. I'm using the 402 DME and am getting it remapped next week on a dyno, will let you know the results, but am hoping for around 220rwhp.
Again, Thanks.

I still love this thread. My OBD2 S50 will be firing up this week. More to come.
