Has anyone installed this or a similar level upgrade? I'm curious as to issues the N20 may have under such high loads. Considering this as a potential future upgrade but not at the expense of reliability. Also would love to see dyno results and just a review in general.

Since I'm guessing there are very few of these in the wild, Dinan if you'd like to chime in and let us know what kind of engine reliability testing was done with stage 4 and any other info you can provide in excess of what is on the website, that'd be great.

I could have sworn I answered this in the other stage 4 thread but I don't see it in there now, alas...

There are only a handful of the Dinan stage 4 MWG N20's out there as the production range for those cars was relatively short in comparison to the EWG variant.

As far as engine reliability testing goes we hammered on our original development car for 20k+ miles without incident and it is has continued to go to this day with its new owner without problem. I will note that we also have the same turbo/intercooler setup in a few race cars we support that have also had no engine issues (JDC 228i being the most known one on a major circuit). If its holding up in the environment of a race car that's constantly being put to the limits I think that's very telling.
