E36 M3 S50B30 Vanos Delete

[Finlay007]

hi all

im knew to the BMW world so any info would be great

just got myself a S50 converted compact, think it might have some Vanos issues in that it is very jumpy at low speeds and lumpy at idle, and when cruising it sometimes seems like it missfires or stutters on/off

so im thinking rebuild vanos or delete it and fit a set of cams, what you reckon ?

can the oem ecu be reflashed and mapped to suit the vanos delete and cams or will i need to get an after market one ?

does anyone have any good links to vanos rebuild posts ?

cheers

Finlay

As you can see from recent dyno pull, power is down by about 50 bhp ( graph in wbhp) doesnt make power over 5k ish, drops right off

Looking to check the vanos pressure after ive just rebuilt it, im gonna tie into the vanos filter port, where can i get a test rig from ? Cheers

You don't need to buy a test rig, just use some brake hose, vanos filter thread is m10x1 then you need a 150 bar gauge and a BSP or NPT to m10x1

Yea i was thinking about making up a rig out of brake fittings, thanks for confirming 😉👍

long overdue update

rebuilt vanos with new seal kit and tested solinoids, found 1 solinoid not operating so carried out some VMC inspections, found a short over the earthing for one of the solinoids, got a bridging wire soldered in, buttoned everything back up, all good, 296 bhp

that was about 6months ago

now im back to power loss again like before and now its leaning out after 5K along with power loss, seriously thinking of going back to original idea of Vanos delete, i have a SCS ECU sitting waiting to be used, just want a reliable engine, everything just getting abit old, wiring, sensors etc gonna be a struggle to keep going over the on comming years

do i go S54 ?

my S50 is in a mint E30 wagon which im not going to sell, thinking of long term here on the S54 idea
