You got a good score on the 5 series

Sort of but you have to harden the shaft or extreme wear i also did one where i double stacked the gears 

All the pumps have a major weak point, the shaft.

I made mine from billet with a new drive system no spline

You've changed...

Nope, im still a "A" hole with a low tolerance to idiots, so just the same old me

Here's a question for someone... is there any oil pump up grades that someone knows about for the s50b30, I was reading somewhere the early 90's pump were smaller than the late 90's ???

Yep make your own, but now im showing off

Seems tad silly doing all this and leave the bottom end including bolts, but hey your build.

As for failures, there was a Z3/4 running one in open bmw N/A that broke the bottom end many times including snapping Carillo rods.

Your call

Cant say i like the bottom end theres no form of craddle, thus i made one and i see you didnt change the main bolts?

#1 rule is the top is as only as good as the bottom.

i run over 11/1 on turbo eth setups, 9:5/1 is fine and will be also if you run pump 98 so dont stress

875 is way to small for eth try ID2000 they will also run fine on pump

That would be me then, they run a Pro35 on the RB30 and HRC40rs 66mm billet in the 2J 

HX40R ?

Lets not forget your average BMW is tuned off one 02 sensor and does hundreds of thousands of km's without a issue, regardless of your requirements its still only as good as the tuner.

I've always wanted to have each cylinder tuned, I have access to muiltiple wideband sensors, but I find myself wondering how I'm going to read all 6 and link them into the link G4 ecu, I should have enough free ports but understand there may be a controller that may be needed

Ok answer this, what are you going to do with all this data and how are you going to make use of it ?

I did a 80k twin turbo big block the other week, once tuned correctly we only monitor 02 readings per bank even then the owner has no idea what to do with the data. ( Cant hold his hand even time he uses it )

Just have it tuned right to start with using the intended fuel, there is no such thing as a "safe" tune however a tune is either right or wrong end of story.

if you think you have time to watch a bunch of gauges when pedaling this thing then your streets ahead of anyone else i know, set within the ecu the limits and setup warning alarms for main parameters then drive the thing as intended.

Monitoring EGT's per pot is a cool thing if you were after the absolute hp even then its questionable to whether its needed, plus EGT's chill off quickly once throttle is closed and slow to respond.

Like i said tune it right to start with, no Knock and dont set it on the edge, go forth enjoy it as intended. 

I would cover the cooling thing but that seems to be covered above.

Hot water comes out of engine, and with any luck cool(er) water goes back in?

In light of that then you dont need my input

Do a google to understand how performance cooling systems work

Famous last words

Thicker radiators don't improve cooling they mask issues 

Just now, WYZEUP said:

It's a cut ring gasket so will slightly cut into the head and the block to handle a lot more pressure and less chance of it blowing out

Used them before, they sit on top of the block and locate within the cut out of the fibre head gasket

oh

Out of interest it that head gasket use the floating rings ?

Cool thanks guys i'm on the fence about it all right now. 

After talking to a few people it doesn't look like i'm going to be able make my target hp of around 800-850 well reliable hp anyway as it will cost a stupid amount upgrading gearbox, driveshaft, diff, axles, clutch to be able to handle prolonged use of it
As sad as it is i'm going to have to admit defeat and just try see what happens at Dyno time with the new mods to the M3 engine only and see if there are any loose links that need attention then
