nice, glad I saw this. it's amazing how much more information there is on M20 builds these days. Part of the reason I just decided to stop on M20s was because I knew I'd have to totally redo my entire motor from the bottom end up. If I knew back then what I knew now I wouldn't have done anything like what I have now in my 2.8.

thanks guys
did the install today and everything fits and runs well.
unfortunately it is a fair bit quieter than open trumpets but still better then stock and dbilas which are too quiet.
definitely alot more power than the socks which lose about 15-20whp but i never drove this setup without socks so i dont know whether it will match the dyno run of 152kw with open trumpets no socks.
still got to find a better sized K&N filter and make a heat shield.....

Can I ask what brake booster you are using?

i plan to get it retuned only a quick and dirty tune about 30min worth tops, i will make a simple bellmouth to be able to test without a filter (bellmouth is needed to ensure the flow doesnt go over a sharp edge and hurt airflow thats is why sometimes removing the filter makes less power as the test is flawed) and one without the lid to see if there is a difference.
im waiting for my new K&N still so i imagine this might happen 2 weeks from now.

not only are the headers compromised due to steering linkage the intake is compromised due to booster. double whammy
the hood latch is also still on the same side. cheap German engineering....Last edited by digger; 05-05-2014, 02:34 PM.89 E30 325is Lachs Silber - currently M20B31, M20B33 in the works, stroked to the hilt...

one way i know the car is faster than i have been used to recently is the inadequacy of the current brakes. will probably need to upgrade the fronts to a massive kit and rebuild the rears....cant fit that big of a setup under the 16" alpinas but a small spacer does allow a couple kits (MAssive, UUC etc)89 E30 325is Lachs Silber - currently M20B31, M20B33 in the works, stroked to the hilt...
