E85 Z4 M Bumper on 3.0L

[cj10jeeper]

And u wont be able to run two exhaust boxes from your 3L because unlike the M where the battery is moved to the center to allow this on the non M's the battery is to the right thus not being able to have the two, so only one exhaust box with the second tail pipe running from this, just ensure the second exhaust pipe is curved as it runs from primary exhaust box as any angles will reduce air flow like some cowboys make that mistake, Remus do a good exhaust box and Eislemann do a great exhaust system but pricey!

Not entirely true. I fitted full dual system with OEM ///M back ones. Just had to remove the charcoal filter. Slim the battery down and fit a race battery instead. Bit more work but the most elegant and pure solution.

Full thread on it on the forum.

Each to their own of course but other than visual appearance it would seem quite a bit of work to add an extra box/ pipe work to the car , with the added weight & poss exhaust restriction . M box's do look rather bulky ( helped if painted black though) to me . IMHO credit to you for achieving this on a non M car though .

Yes it was a lot more work, but the effect is much better. Not only is it a proper system rather than a 'T' pipe, but performance improved marginally as it was less restrictive than the existing box. Sound is much better and extra weight was compensated for by swapping out a heavy battery for a much smaller race version and removing the charcoal filter and associated crap.

Bottom of my boxes are painted black and since I also added an OEM CF diffuser then hardly visible.

I certainly would not recommend this route to someone who just wants the effect of quad pipes and doesn't have access to lots of equipment, but was more pointing out it is possible.

Just a quick question, if i installed the Z4M bumper, would the lights from any E86 be ok ? a local scrapper has a 2007 E86 2.0L with the tail lights available, not offered any money yet, but would these work ? or do they need to by from a Z4 M ? Im assuming just the bottom of the lights were changed on the facelift and the top half is the same shape / dimensions ?

Also, will they plug straight in or will some re-wiring be required ?

E86 is the coupe... so def not a 2.0L.

If you mean a facelift then yes... any facelift will do.

Also you will need to the rear light surround.

They wont plug right in though... you will need to look up the wiring and recoding needed.

no any facelift light wil do, as the M light is the same as facelift lights. there is do differance.

 

[AndybZ4]

will the headlamps from a facelift E86 go into my prefacelift 2004 E85 ? or is this not straight forward either ? i would love to replace the units with the amber indicators for clear ones !

Andy - please start using the search function. There are many detailed threads on swapping lights, removing amber internals, etc.

NO ! And if you'd be using Google you would've known

Yes Andy, the headlights are exactly the same on a e85 and e86, the front bumper mounts are the same. So an msport front bumper from an e86 will fit and e85. Careful not to confuse e85 (roadster) with an e86 (coupe) where the coupes are facelift only, but you can get roadster pre facelift and facelift.

The issue you may have with headlight is that the voltage is different between xenons an and halogens, the can be changed easily by coding the LCM, I could do this for you, or many other members who have bought the cable and software.

To answer the rear light question. The tops I believe are exactly the same on the facelift lights, so where they meet the boot and rear wings should be fine, it is just the bumper that needs to match the lights, there is not difference in light between an msport and standard.

 

[Bad_Pritt]

the answer is pretty simple: if you want the facelift lights and real quad exhausts, get a Z4M or at least a newer Z4
If not, I would leave the lights and the bumper as is, there are also plenty aftermarket bumpers out there that will fit your current lights AND a quad exhaust with T-pipe...

But seriously, guys on here are right: do a little more research on this forum first to understand how complicated it is what you are asking.

 

[ben g]

some people are proper angry guys on here. if no one ever bothered posting about these things, then this forum would just end up being an encyclopedia.

just recoding, from what i learn on the the threads it's damn hard to make them work, recoding/re plugging and if you want to do it the right way you have to change the wiring, so it is'nt a straight fit it needs work.

straight fit = no work accept connceting and mounting them. just my 2 cents. i've read you front light conversion earlier on, and it seems hard to make it work, especialy when you don't have coding skill/ equipement.

Nope, e86/e85 are exactly the same. The difference is xenon to halogen, with LCM which if I did again would take 10 minutes.

 

[Lightning87]

and xenon to xenon than ?? as maybe i can get my hands on facelift xenon, as i now have prefacelift xenon's ( with the flash to pass stil halogen )

 

[Mau]

As I understand it the connectors at the back are completely diferent for facelift Xenon and pre facelift Xenon and rewiring would be involved.

Then again; that's just what I read on the German and Dutch forums and not something I checked myself. :?

 

[aquazi]

Pre facelift to face lift xenon's is not a def not a straight swap. Very few people have done this... maybe bmwZ and mac27040 (who did a write up).

But this has somewhat digressed from the original post :lol:

Rear lights facelift upgrade

Right if upgrading rear bumper to z4m then you will require facelift lights and new light frames as they are different to pre-facelift. You will require facelift rear bumper top mount and unless bumper comes with mess then that as well.

Also you will need to make a bracket to fix the lower part of the bumper (middle section) as the m bumper doesn't line up the a non m floor plan. Easiest way is to cut old bumper up and bolt to new bumper.

Rear lights require pins in plugs to be swapped round, also bulb holders need cutting down as facelift lights won't line up with holes in body. Finally LCM needs coding to give 12v to lights and switch T effect off.

Facelift xenon front lights

Upgrading from pre-facelift xenons to facelift requires some wiring changes and coding. Flash to pass need changing as on pre-facelift it uses inner lamp but on facelift it uses xenon. Only way I got them to work was to have DLR so xenons on all time and wired flash to pass to xenon shutter. You also need to code LCM to not check for bulb waning as angel eyes draw less that original side lights thus car thinks bulb out.
