Z3 2.8 remap after big port inlet manifold

Post by ben5010 » Fri 25 Mar, 2016 22:48

Hi all

I've just installed the larger port inlet manifold from the 330ci onto my bmw z3 2.8 m52tu, I'm looking for a mapping company near London who will accommodate for the new manifold on the remap.

Thanks

Hi Ben.. l appreciate youve got to get it re-mapped but is there any immedate difference from just fitting the manifold?

To be honest, I don't drive the car enough to notice a difference, but it's the equivalent of the m50 manifold swap on the older 2.8. The M54b30 manifold that I fitted has much larger ports than the standard m52u.

Anywhere around London, or even the surrounding areas. I don't mind driving for a good remap.

Not worth it if you use car as DD and not for track days. Probably just shifting torque from low rpms to 5000+ rpms.

I have recently done my M52TU car and notice a big difference from 4500rpm onwards, It has a real surge.
Below that I have not really noticed much loss of power.
It is great for overtaking, I just leave them standing.
Not remapped as yet

I have an element of 'M-styling' on my car, If that's a good enough reason for the manufacturers to adorn a 320 with the M badge, then its certainly a good enough reason for me..

The bigger manifold allows alot more air compared to the standard, it isn't just a case shifting the torque from lower down. Obviously they require a remap to fully utilise the greater airflow.

Getting a remap tomorrow, also took the car out for a good drive, there is a noticeable kick at around 4.5k compared to the stock manifold setup. Can't wait for the remap to compliment the new manifold. I will try and get a dyno printout up too.

I did the intake manifold swap on my 1997 / 2.8 and then had a re-map. The company that did it for me asked me about my driving style - ie. did I habitually race from traffic light to traffic light, or was my style more "cruising" etc etc... they then do the re-map to best offer the power where I would likely most require it. Obviously, the intake change is taken into account as an overall condition when doing the re-map. And there was a noticeable general improvement in power, although I can't say it was neck wrenching.

This is a good video to look at though..... https://www.youtube.com/watch?v=03nL8Z0dRkI

I would have guessed that this manifold swop (when combined with a proper remap) would make a significant difference. I had a “stage one” remap done on my humble 1.9 (140 bhp) by a reputable and recommended tuning firm and they took it to 152 bhp after several hours work on and off a rolling road. Another 1.9 forum member had a similar result elsewhere in the UK. A 10% increase is noticeable but obviously it doesn’t change the car into a completely different one.

The firm I used wouldn’t do a remap on a car which was badly maintained with broken engine components and/or badly botched DIY turbo kits etc. My impression is that this generation of BMW (non M) engines were deliberately “under tuned” to cope a certain level of servicing abuse and varying petrol quality around the World.

I didn't end up getting the remap, I will post up the results when It gets booked in again.

Hiya mate. Can I just ask you about the inlet manifold conversion. Do you have a 2.8 twin vanos? I have a 1999 twin vanos and have been looking for a conversion for mine.

Yes this tread is about the 2.8 twin VANOS engine otherwise called the M52TUB28 engine. They are fitting the inlet manifold from a 330i or similar car that is fitted with the twin VANOS 3.0L engine (M54B30).
