Hey guys I'm getting the part this weekend so I will be able to take pictures and get this thread back on track

issabmw · 05-21-2010, 02:28 PM

Does anyone know if 19x9.5 et45 rims running 265/30R19 tires will fit up front on an e90 xdrive prelci?

I'm still not sure about this 3 stage manifold....base on E90fleet (a well known member from the past) N52 already have 3 stage MF

ska///235i · 05-21-2010, 04:18 PM

here also talks about the old M54 engine had a 2 stage DISA and the N52 had the 3 stage and how it works

so what prove we have that only some N52 had the 3 stage?

the 325 has an N52 but single stage manifold. Yes, only SOME N52s have the Three stage, there's no disputing this fact.

read the diagram carefully

Three stage on HIGH OUTPUT version only

Hope this clears things up.

It's cool. At first I was lost too. Now after some research I know my stuff.

What's HFM?

I believe that HFM is the high flow mass air meter and is similar air intake/manifold modification for easy power gains in NA e36's

I heard from somewhere that the 328i has a 2 stage intake manifold?

m_thompson · 05-30-2010, 01:34 PM

My N51 has DISA.

328s have a single stage in the US if it's an N52. The euro 330 has the N52KP high output with the three stage intake manifold. The N51 has a three stage I think but a lower compression ratio.

akafurious · 06-01-2010, 10:09 AM

Where to buy parts for the 3 stage intake manifold in Toronto, Canada. and also what is a good OEM Parts website to buy parts for the conversion mod that can ship to Canada, i know the getbmwparts.com wont ship international at this moment.

BlackBimmer1991 · 06-01-2010, 11:35 AM

If you pay me enough I will buy it and ship it to you

ianbiz · 06-02-2010, 11:08 PM

When this is done. I would love to meet you and "compare" my 330i w/ your conversion. I saw the previous attempts to do this (almost attempted to DIY it when I had a 325) but did some math and figured I was better off buying a 330 (in the color/option combo i wanted).
Props to the guys working on this project

Anyone know how I can confirm that, I've checked the engine, there seems to be DISA but I can't be sure.

e90pilot · 06-03-2010, 09:39 PM

Yup, it has less compression for sure and has the 3-stage intake manifold. It has the same part number as the 330's.

Evice · 06-04-2010, 07:44 AM

As 128i owner, I am very excited about this. I always dreamt of 130i sad they never brought it over to US! and this might help a lil. subscribed.

scanboy · 06-04-2010, 03:56 PM

does it mean I could get close to 330 number with Gintani's tune?

e90pilot · 06-04-2010, 11:12 PM

Your car has the 3-stage intake because it has lower compression. It would have very little power if it didn't. You can probably tune it, but you won't be near 330i territory.
