Lets build a MS43-turbo system! Specs etc...

Hello guys,

anyone interested in developing/building a turbosystem for M54 based engines?

Id like to start a build next year with hopefully a 325ti@M54B30 and as i want/need it absolutely stealth, i was thinking of doing something like a group-concepted build. It seems to be working good at headers and that stuff, why wouldnt it work at chargers.

I know theres already a kit available, but in europe its not that easy and honestly im to much engineer to just buy a kit.

So, what do we need to build a turbocharged system? Which components are known to be working? whats the performance looking like?

A few of these questions im going to answer in the next days, but be aware im not directly into uber high performance figures! If someone is interested in 500+hp, that definately need better parts.

Is anyone interested in that topic and are there some folks which already want to give some input?

Figure out the tuning first, the rest is a piece of cake.

I don't think Daniel worries too much about tuning; check out some of his other posts.

I don't worry since I found out how hard it was to tune a ms43 dme I just went and bought a M3 instead . Only a couple companies that will tune the ms43 and for the cost your are better going with a stand alone system

You still don't understand,.....Daniel_f. has the ability to tune it himself.

I understand now,,,,,dumb me! I would look at all the other turbo kits that are being offered for the M3 and just copy one of those kits then

Everyone has the option to tune themselves now. It works great.

Daniel's XDF's work great as well, the only drawback for it right now is lack of software availability (specifically for MS42) making flashing on the virginized software a bit of a hassle

The e46 aftermarket performance community has had many doors opened recently.

So you said stealthy, but how many horseponies are you trying to achieve? Are we going all out and changing internals or are we going for a mild set up?

Daniel, can I suggest you invite GeorgeG to this thread, his knowledge and yours combined on this subject could get very, very interesting. Only person I know of who has done both rhd and lhd turbo non m.

GeorgeGG is kind of on a different path, his path is more along the lines of a e36 into a e46 body, using a standalone iirc

I think Daniel's goals are to turbo a m54 with ms43!

my input on the topic...

timecerts! I use 11mm certs but if you really want to do the extreme, contact "bluejeansonfire" he had steel slugs custom made instead of certs.
I wouldn't recommend turboing without doing this.

the spa manifold has worked really well for the e36 crowd and fits fairly nicely in the e46 (the one im using)

also as far as tuning on the ms43 we will need to overcome the issue with having 2 banks of exhaust gas going into 1 bank, nick g figured out a way to make the ecu read bank 1 02 sensor only. unless you decide to try and twin turbo the e46.

PEI330Ci has some really good info on the m54 also, maybe he can add some stuff.

Ive read his thread yesterday and youre right, thats completely different to my goals. Hes going the "american way" (in my opinion!) by charging as much as he can and constantly changing broken parts. Thats nothing im interested in.

Interesting idea! I needed to google it as ive never heard that name, but the parts themselve look somewhat familiar. Ill be doing some calculation on the headscrews, but as long as we stay in the power levels of similar (super)charged kits, i think its ok to compare with their changes.

Well, question is do we need the lambda sensors... MS41 is already dissassembled (next to MSS54) and its common knowledge how to fool the ready-monitors. MS43 seems to dissassembled and maybe that guys can/are willing to help out here. If not, im confidend well find a different solution by tricking the DME.

Id like to use one of the inputs for widebandlambda monitoring

No offence to Daniel, because I believe his intentions are genuine, but I'm just not motivated to comment on this stuff anymore.

Most of what I suggest is disregarded, or criticized. I don't take it personally, but it is a trend that doesn't encourage continued participation.

My son in contrast, follows 90% of what I suggest with Lego....so that's where my time goes.

I still answer all direct questions as best as I can.

What Lego suggestions could you make ? The forums are taking up to much of my time & I feel that Lego just might be the answer.


I couldn't help myself,

And now I'm motivated to build a DME out of Lego.

Will report back shortly....

[QUOTE]

its a cast manifold, places the turbo high enough that it doesn't require a scavenge pump. available in t3 or t4. been proven to 800+hp iirc. lots of info on bimmerforums if you search for "spa manifold"
