FBO 135i to FBO E89 Z4 35i

[Lambobimmer]

I replaced my 135i with a 2009 Z4 35i in January. I have finally installed my mods and I thought that I would share a few vids.

Cobb Stage II aggressive tune
Milltek Exhaust
AR Catless DP's
HPF FMIC
KW V3's

This is 0 to 80 mph

This is 0 to 100+ mph

Z4 is a little faster than my 135i because the DCT shifts faster than I ever could.

Enjoy

What a wonderful state to own a fast car in, I spend a fair amount of time in the research triangle visiting family every year, and I'm always a bit dumbstruck when I pull out from their gated complex thingy and 15-501 is staring me straight in the face. If I went WOT on my street, i'd be halfway into a neighbors backyard or through a stopsign in a few seconds. Lots of room out in your neck of the woods...Oh car looks great too

Nice swap, but check that exhaust dude, sounds like there's a leak.

So op how does it compare to the 135?

Do the cars share some of the N54 mods? Like downpipes or intake, charge pipe, FMIC, etc?

Same mods except my 135i had an intake, charge pipe, lsd, OCC and Front SWAT which my Z4 doesn't have. I switched to KW V3's on the Z4 and my 135i had BMWP Springs and Konis.

The Z4 handles better and shifts much faster because of the DCT. Both of the cars had N54's.

However, the best option on the Z4 is the ability to drop the top.

Not sure what is going on with the exhaust. I don't think that it has a leak but it might be rattling against something. It does sound a bit raspy.

In the video it sounds like a leak, just might need to tighten it up. If its a rattle it could just be the brackets holding the exhaust up.


I've always liked how the Z4 looks, I may look into one later. I like having a minor amount of room in the 135i though, lol.
