Upgrading turbos on the Z4
Hi,
Im thinking of upgrading my turbos by increasing the size of the turbine and compressor wheel. Has anyone had this modification done on their Z4. What could be the problems?
The 135 and the 335 community have recommended that I go with RB Turbo since they have experience in doing this modification and the other BMW's havnt had any issues.
To compliment the turbos I will be getting a stett intercooler and downpipes and hoping my car will pull 500hp.
Also can anybody recommend a tune. A few people have recommended JB4 any pros and cons?
