I confirmed the price with Travis at Power Chip yesterday. He said they would give a discounted price if you mention Marcelo's name. It sounds like I better get my hands on that manifold...

Props to Marcelo for taking the charge on this one!

how do i get in touch with this guy? can someone PM me the number and address?

where do i get the parts? buy it from bmw? have them order it?

i think the 328 engine is a little different, and it is the same and an X3 (3.0SI)

so for us with the 328 we would need the x3 manifold?

i thought 325 and 330 have same engine..?

I cant believe I read every single post [and looked at every link] over the last few hours O_O"

your right, but i have a 328 so i would need an x3 si manifold, i dont think i could use a 330

Yep, did the same here a couple weeks ago. It's great to see someone make progress on this though.

I was wondering if the intake swap is a fairly straightforward DIY job or if it's best left to a shop?

I've been looking into a DIY. Here's what i found. I haven't done this yet but here's a what i found. You need to attatch your motors to the new intake first. Then you need to remove the airbox. Also it looks like you need remove the hoseclamp from throttle and the undo all the bolts and the connectors to the sensors. Try to remove the intake with the throttle and sensors still attatched. Then move the sensors to the new intake manifold. You also need to replace the gaskets. Re attatch all the sensors and connectors and attach the actuator connectors (not sure which one goes to which motor). That should be it? Easier said than done! Haha! I just took a glance in the engine bay to figure it out but I'm sure it's more complicated. I'm also having a mechanic do the install. Parts will arrive next week. Don't worry, the suspence is killing me too!

very interested as im a 328i owner too......

I'd cross-reference the part numbers. There's a pretty good chance that the manifold is still the same, or almost the same. The 328 still uses the same cylinder head, which would mean the intake ports should have the same bolt pattern. Check the intake manifold gasket part numbers too. Even if the IM is slightly different, it could still fit.


EDIT: I just checked for you guys. The part numbers are the same, the E90 330i, X3 3.0si, and the Z4 3.0si all have the same intake manifold. So that should open up a lot more options for people trying to track one down.

Not quite. Monday or Tuesday hopefuly. For those who were wondering, it's about 2.5hrs of labor to install the intake. BMW reccomends you run their intake and valve cleaner too especially for high-mileage cars.

im sure it should be diy able right?

Yes but definitely difficult. Limited workspace and bolts in a very soft engine block. I'd rather have a pro do it instead crossthreading a bolt into the block. Also you have to manually thread the plastic of the intake manifold. If you mess any of that up... Yikes.

updateeee?

Well, I just checked with the parts dept and they're still waiting for one of the screws. The bad news is it's in Germany. The really bad news is the fact that that screw is completely custom (5x66mm) so you can't pick it up at a hardware store. I'm gonna order like 10 in case a break a few lol.

[tharptroy]

Just get some bolts or screws and cut them to length. I had to cut 5mm off of my extended wheel bolts because they were hitting the emergency brake.

lol.. damn screws!. hey so how much you spent so far?

$1440 so far. It will be about $250 for installation I think. All in all not bad for 60hp gain in a BMW. I'll probably get it on the dyno. Too bad I didn't dyno it befor I got the software. There is a possibility though of restoring the original software for a dyno run then reapplying the performance software. Don't hold your breath though. I could just find someone with a stock 325i and use that as a baseline.

The parts departament was able to obtain a screw for me so I don't have to wait for the one in Germany. Hopefully I'll be taking the car in on Monday or Tuesday. Slowly but surely we'll get there.

yea.. everyone has a stock 325i +/- 5 hp wouldn't make that much difference for baseline.

Funny I just did a baseline with my steptronic this morning. The tech could only get pulls from 5,000 to 7,000 rpm because the tranny would drop down a gear. We were getting pretty consistent results though. Most pulls came out with max hp at 181 and torque around 161. What I've seen from others the max torque should be between 3,000 to 4,000 so mine should probably be higher. The reason for the dyno was that I got my hands on an intake. I'm just waiting for a few more parts to show up at my door. Once I get them I'll put on the intake and do another dyno trip. FYI the 325 DME already has the programming to open the adjusters. I did a quick test yesterday. Now I'm dying to know if we can get an increase just from the intake??? Either way here is an average pull and then my best for a base line on a totally stock 325i step:
