3.1L turbo ix

[nando]

the main thing I've seen broken are front differentials. it's a type 168 (small case) but the internals are the smallest of any BMW diff. the E34 and E46 also use a type 168 front diff but they're much stronger inside.

^ but e46's don't have 3.91's though. I don't know about e34's. Any way around this?

[nando]

It doesnt matter, nothing from an e46 or E34 will bolt up.

well the theoretical possibility:
if you place small boost it might work with this setup:
85mm overbore + m57d30 crank (90mm stroke), that would make 3063cc
but if you want use good boost, i prefer to stay in 84mm bore. m20 shares cylinder division of 91mm so there wont be much wall to left.
Also if you want to give it huge boost, you'll need to add copper rings or steel gasket.

my friend Matti's ix

transfer case and front shaft stays original exept he bought front shaft spline uppgrade from me.

He has made front differential to last with adding extra gears into it (page 3)





then his front final drive crashed. now he is going to fit Opel omega LSD to front.
he has "I"s LSD on rear.

Also he mentioned that he is trying to add second Universal joint to front drive shaft, so it would soften power transfering to front diff.

typical problem is with the gearbox that when you have too much torque, it will start to bend its axles while accelerating. he has broke 2 gearboxes, both times when using 3rd gear. should make iron shell and stiffer axles

[nando]

doesn't he have like 700hp though?

you wouldn't really need to do any of that for ~300hp. as long as you're not drag launching it all the time, it should hold up fine.

[jute91]

he had ~800hp last dyno, now he is trying to brake 1k hp limit.

all those uppgrades are just for in case IF it happens which usually will happen, "hunger grows while eating"
means more boost

^ That's awesome!

Wow that's pretty intense.

Just had a thought. I don't know too much about transfer cases but, the transfer case in an ix splits the torque 37% to the front diff and 63% to the rear diff. Could you use different sized planetary gears to reduce the amount of torque being sent to the front diff? Allowing for a higher overall torque being supplied by the engine. I believe this would also give you more of an oversteer at the limit of grip. Don't know if this is feasible, just an idea.

[nando]

No point. Just get a rwd car instead.

Im working on a solution to use a 6spd with a Xdrive TC, with this you will be able to do this :)

Surely, you must be trolling.

LoL

post pics please. You swedes are always up to no good. :shock:

I kind of put it on hold untill winter season. Have to find a way to control the TC. Will use ATC300 from E90 xi.
Main focus right now is getting complete 525ix drive train in the 325ix :) And a turbo ofcourse.

That is possible, but why? AWD means that all wheels are pulling the car forward :D
If you want to make it rally hard, you should start moving weight from front to rears... Its the heavy 6 cylinder block that weights lot with front diff and transfer case.. My choice would be moving the engine more to back. moving alternator, radiator and all that can be into a trunk.. thats rallycross way..

my rallycross escort has all these tricks done. also some body has been replaced with fibre glass to reduce weight.
It weights about 950kg while 650kg at the rear wheels.
