Hello, just paid the deposit on a Z4.

If you can, the 2006 or later facelift 3.0i with N52 engine is the best. You can upgrade the 3.0i to 3.0si with retrofitting the 3 stage manifold and simply flash 3.0si tune to boost 215hp to 265hp. But this setup only seems only being sold in US. In UK you can find N52 engine facelift 2006 and later 2.5i and upgrade to 2.5si with 3 stage manifold and flash. Will boost 174hp to 215hp. Plus the facelift model had steering control button and 6 speed automatic trans, also more advanced DSC system module.

Just saw a 2003 at the Facebook marketplace, and the roof motor hasn't been moved. Alan? Alan?

FWIW we never got a facelift 3.0i in the UK, they were all 3.0Si. But he's right about the facelift 2.5i upgrade to 2.5Si power. The bonus with facelift cars is all the Sport models have the M-Sport seats as standard.

Any chance there's a video that recorded your method? 15 mins to relocate the motor sounds fascinating.

I charge $1000 now to help other Z4 owner around my area to rebuild the hinge also relocating their motor, relocating sometimes will cost about an hour or more especially if someone elses had opened the motor casing previously and sealed the top with loads of tapes.

It’s quite simple. Unbolt the roof ring about half way round. Unbolt the hinge. Unclip the loom fasteners. Pop out the roof seal and lift it up

I did this method in about an hour having never done it before and taking my time, I gave up with the break the motor free method after about 10 minutes as it seemed impossible or very much likely to damage something, when I saw how the casing is attached with a screw and cable ties I'm glad I partially lifed the roof.

I found the most difficult part was clipping the hoop back into place
