to pass emissions and do headers its not worth it. If your inspection does not hook up to a sniffer, then get catless headers and install O2 sims. If you have a sniff test in TN then dont bother. The Cats are what restricts the exhaust and creates back pressure. If you dont want to deal with that. Start with the intake manifold and get a BMW performance or GruupM intake and open up the exhaust more.

I never had to do the swap bc I have a 330 but I'm 90% sure you need a 330i TB, and air box as the piping is all larger.

E46 Dyno Thread

i've read a lot of thread about the swap, but they swap just the manifold, not the tb

i already bought the manifold include the disa and the TB.. it was pretty good deal, thats why i bought it..it was parting out car from 330..

i know about the piping, the seller include the piping from the tb to the mad sensor..all i need is just an adaptor to the map sensor...

what do u think guys ? shoul i use the m54b30 tb or use my m54b25 tb ?

Well you could hit 200 plus WHP on your 2.5L, but it would be reasonably expensive to do it. I could give you the list you'd need to push past the 200 plus WHP mark, but it sure would be much easier to go with either Nitrous or a Supercharger.

BTW, there's nothing wrong with 161WHP from a 2.5L.

could u list it ?

well supercharger is my longterm project..i want to hit 200 HP first...or atleast 175..

i will be put 330manifold and 330 TB...after that, im gonna do some x pipe on the exhaust..

need to tune the dme..if somebody can teach me, i will be so happy..because its really hard to find someone that can tune the dme/flash the ecu in here (nashville,TN)

i know header will totaly pull the hp, but i still dont want to messing up with header, because i want to find some header that can fit the cat and o2 sensor so i can pass the emition test every year...

any idea about camshaft ?

^ from your response I can easily tell you're not ready.

So for now, no list.

Keep in mind this is not a "Magic" list, all this info is here in this sub forum already; search for it, you'll gain some knowledge.


Good luck.

Here's my plot from the dyno tuning session today. We did about four hours of WOT tuning on the dyno (35 runs) and another 4-5 of part-throttle to get the car running right. We were getting a lot of heat soak (I need to make a shield for my intake pipe). I suspect if we had let the car cool we would have seen higher peak numbers, but I don't really care about the absolute numbers.

Peaks of 230whp / 228 wtq

Mods:
M54B30, 0.030" over, ZHP cams, running Megasquirt and E85 (flex-fuel)
Technik V3 headers into Burns megaphone collector to 3" pipe, two mufflers and a dump before the diff
Decked head
Mild head port blending
M50 throttle body bored to 68mm
Long-tube 3.5" intake, filter in driver's brake duct

There is probably a little to be had between 2,500 and 3,000 RPM but the car is never used down there so we didn't bother spending a lot of time on it.

Wow, very smooth!

Wish I could go mega squirt, giving some thought to a piggyback, but it's not likely to be worth the cost in STX...

Best part... No more nonlinear electronic throttle! The M50 linkage is so progressive....

Wait just caught this, Does this mean our intake track is severely restricted at the MAF or that the engine responds really well to a solid state tune where MAF reading fluctuations are eliminated?

What do you mean by a "solid state tune?"

If you're asking why the difference between the blue line and the red line, the answer is not because he removed the MAF.

Megasquirt is speed density based, not MAF based, so he didn't need the MAF. I left the MAF in on my Megasquirt setup (though it's not used) and made a little more power than hoveringuy. It's not a restriction.

79 degrees and 60% humidity. Third run was the best. No stock runs to compare it to, but seems pretty good to me. Running rich (extra safe) though. Maybe some slight gains to be had by leaning it out up top, or not worth the hassle/risk?
