Here is the link but currently it isn't even working properly. https://www.j-spec.se/motor/motor/in...d_grp-s1%2F505

But you can try asking them.

I went to this website and it doesn't show the intake manifold out of stock, it doesn't show it at all. They must have stopped making them all together.

Deluxe. That'll sound so good if you've set it up for "antilag" style flat shifting.

Cannot wait to see videos of this in action.
I've been tossing up a holiday to northern Europe for a while, I might have to time it with the airstrip meet that you guys do.

Will it do flat shifting, triggering off a clutch switch?

Yes as the ms2 can also. I have now clutch switch in both cars using OEM cruise parts:


Previously we had our own mount, but it was too flimsy.

Should be a fair amount of extra beans with another half a bar in it

With e85 that should be close to 700hp if everything works out fine. One engine in Finland with very closely same setup, gave out 666hp with slightly less agressive cams.

Just noticed that ms3 allows antilag in addition to everything else :devil:

Can you post a link for the intake manifold? That is exactly what I have been looking for. If I know the makers name or can be put on a waiting list that is fine. I would really like to purchase one.

Off the shelf one. It was only 400€ in sweden so really good deal. Million times better thabnthe chinese eBay intakes that ypu can get for same price. But after I posted link of those to Finnish bmw forum, all were sold in no time :D should be much faster. I got now 4-way mac valve for boost control, so now we can raise to boost to desired 1.5-1.6bar area. Last summer we only ran 1-1.2 bar boost level. The ms3 is only for driveability upgrade plus the fancy stuff like proper flex fuel, boost by gear etc. and the intake to level out the AFR between cylinders. The m50 intake doesn't provide even AFR on boost.


Thanks!

Is that an off the shelf manifold or custom made?
Excited to see how fast it is once this round of work is done

For my e30 it looks like I managed to fit the ms3x parts inside the ms41 ecu:




Also got the ISL9V series ignition drivers for the both ms3x builds:

Here is the e34 rear subframe from the ONE. Stock e30 subframe looks quite puny compared to it.


And here is the new intake for the ONE. And new coil wires. Hopefully those will hold the sparks inside and not jump all over like the old ones did. Those are also longer, so we will move the coils underneath the intake to cooler place.


Open style IAT sensor because the stock m50 one is slow as hell for speed density use.


First we took of the stock m50 intake:


Cherry hall sensors fit well using the adapters we have:


And the intake also fits:


Very well to be precise. If you look closely, you will also see flex fuel sensor I mounted to frame rail.

Only problem with that intake was the wider e34 radiator which causes the coolant hose to be exactly where the throttle body should be:


That could fit if we would flip that upside down. But then it would go trough the hood and look very ugly. Fortunately we got spare m52 throttle body, which is more compact and will fit once we took some stuff from it that we wont need:


But that was all we had time. Next we will swap in the euro s50 oil filter housing to have oil feed for the cooler:

Nice e30

Yes I could have used the surge tank but there is two reasons I wanted to get rid of it. First the noise from the carter pump that pulls fuel from stock tank. I could have replaced that with in-tank pump. But if I have to do that, I can just use in-tank pump without surge tank to simplify the setup. Secondly the fuel stuff on the trunk sometimes makes nasty smells inside the car even when nothing is leaking. So it's better to have all fuel lines running outside the car.

I'm well aware about the starvation issue. I just need to keep enough fuel in the tank to avoid that. And also I'm aware that the stock fpr is too small for that pump. If you did read my post, I'm going to PWM control the pump using the ms3 so that I won't have those fuel pressure problems on idle/cruising.

The white ONE has e34 subframe. I have stock e30 subframe on my brown e30.
