Hello dave, thanks for typing all that! I don't have traction on mine, thank god! I did have on a previous BM and although it saved my wallet once it was pretty crude in the way it intervened. If you've got it you'll know what i mean! I had a long chat with ian the other night about said manifolds. Its interesting that you say its from a j plate 325, It must have been a 24 valver, but was it the vanos unit? probably not on a J. The reason I mention is that if you have six fins countable before the TB on the intake side of the chamber you are slightly disadvantaged (i don't know why yet but will investigate). These manifolds were also fitted to the early 525i's with the M50 lump. How many fins do you have? Having seen how much machining work ian does to get everything to fit i would be interested to know how much grief yours was to fit? When you did yours did you remove the gauze from the mass meter? I am fitting on the weekend of 10/11-07 so I'll keep you posted as to the differences. Don't want much do i!?! |

I didn't get the kit from Ian (Alpina 527) as I came across a manifold from a knacked J reg 325, so I changed it myself. So on the induction side I have M50 manifold and cone filter. I don't have the big bore throttle bodies yet (would like to know what benefits these have as a single upgrade, rather than with the manifold/air filter etc). MG Rover released a bigger bore TB (same ratio increase as Ian's TBs) and I bought one for the MGF, although it made quite a difference to response esp. at lower revs, it didn't do much at higher revs. Maybe thats the characteristic of that combination, so would like to know what difference it makes on the 328 as the bore size is the same as the 325. Before M50; The revs tailled of after 5,000rpm so there wasn't much point in revving it further. I fitted a sports cone filter and this had a slight improvement. It created a nice bark over 5,000rpm. After M50; at first I didn't notice a big difference, possibly a smoother better power curve up the revs. But then after a day or 2 it started to get faster, possibly the ECU tuning itself to the different airflow. Now it will go straight passed 5,000rpm and will go over 6,000rpm and sometimes esp. on the track, it hit the rev limiter at about 6,500rpm. Also it was more lively mid range. The induction noise also changed at about the same revs as the old manifold started to restrict (4,500rpm), so from here it pulls notibly better!!! It now gives a nice 6cyl. induction worble at 4,500rpm where as before it just did a bark at about 5,200+rpm, then you had to change gear as it ran out of puff. I would like to see what power it has on the RR as before the M50 manifold, I got about 200bhp. I am also considering the bigger bore TBs. Does yours have traction? Not sure if this would cause a slight dissruption in flow as the air has to go thru 2 TBs. The non-traction induction does look simpler than with traction. |

I am purchasing this manifold kit today from alpina527 for my M52B25 (323i) and will post back the results. I can vouch for him thoroughly, he is a decent chap, very helpful and knows his stuff. more info to follow!

Dave - just seen your request for the article. I'll see what I can do - but probably shouldn't post pics on the web for copyright reasons. Will try and locate my copy of the mag and let you know HF |

I toyed with the mod while I had the 328i...
What car do you have now, I thought you still had the 328. My mate has a garage and gets the odd damaged car in and says hes got a 92 325, so i might be having a look-see at the big black ribbed bit!! |

Nope, that's not my car. Chap on another forum.
I toyed with the mod while I had the 328i... might have done it eventually, but only in conjunction with the big bore throttle bodies and a remap. As for CAIs - I used the BMC CDA @ £170 delivered. Think a PiperX Viper comes in at £250, GruppeM @ £585 and US ones from £150-£400. |

Yeah, seen that.
Just wanted to see the feature. Is that your car? If not are you going to do the M50 mod? Nearly done the cold air box, its turned out pretty much the same as the one on that link you gave. got a nice big sheet of aluminium to make it out of, and maybe more if anybody is interested. By the way, do you know prices of the cold air boxes? |

Hans,
Could scan this article in and post them here?, or e-mail them direct to me, as I've looked for the mag but can't find it. As I'm interested in this mod!!! |

To be fair, it's not the same job... I never did get to the bottom of exactly what the 'engine kit' was. When I stopped investigating, I had come to the conclusion it was at least an HFM, Exhaust and remap with maybe another couple of bits guddled with. And the 4k included travel and accomodation to go over to ACS themselves to get the work done. |

hell fire, 4 grand would buy plenty of nappies in our house. I like Chris Rossiter, and i even had the honour of frightening him around Donington last year but, im not prepared to skint myself by lining his pocket when i know a man that does the same job for a few hundred quid! p.s if anyone gets the chance to ride with Chris in his E30 sport evo, then grab it with both hands. He's a very talented driver. And Chris, if you read this, i look forward to seeing you at cadwell park BDD |

i had a look through the schnitzer brochure today, and they offer essentially exactly what ALPINA527 is doing. they quote an increase of 25 bhp over standard. i did'nt get a price though, but knowing schnitzer, it will not be cheap. their kit is available for 328 and is also featured on their 3.2 conversion. (this 3.2 conversion is based on the M52 328). im not sure if they modify the throttle body. as for my car, it seems to be getting better on fuel now, the e.c.u must have settled down a bit! can anyone remember the Total BMW feature of the black schnitzer touring s 3.2 ? i have the copy here somewhere, under all my junk.
