M135i Pwg Build Thread

13B · Yesterday, 02:01 PM

Just recently bought this manual bmw 2013 m135i, only just learnt about difference between pwg and ewg. Would prefer ewg but stock power, pwg is good. Will be going hybrid turbo most likely pure500 so shouldn’t really make much of a difference. Plan for the build is going down the club sport route, aiming for around 420bhp.

After about 1000 miles or so the boost pipe from throttle body to Intercooler popped off and broke. Seen this to be quite a common problem so updated it with a alloy one from eBay, fitment was really good. Bit of a pain to get old one out but once out, new one went in easy. I did replace both the o ring seal with genuine bmw ones from the local bmw dealership. I do plan on replacing all the boost pipes for alloy ones for better flow and reliability. I also changed out my wing mirror turn signals for some dynamic ones.
