Oh Savo and you Peugeot engine bashing... tsk tsk.
First lets compare apples to apples - comparing a NA motor to your beloved 4G63T is just silly. The proper and fair comparison is the non-turbo 4G63, and in that comparison it's a flaming pile of shite compared to the XU9J4. 130HP? I looked and looked for any praise at all for it - but no such luck. I did find this again though: http://www.caranddriver.com/flipbook/the-best-naturally-aspirated-engines-of-all-time#33
You likely have a leg to stand on with the 4G63T against Peugeot's production turbo motors - but I've also had lots of DSM hardcore friends simply burn out from repeated and most epic unreliability break downs that 2 when Nissan and the other 3 went into Hondas because they were sick of the constant failures...
That said they still have a huge following and a massive aftermarket - but the fanboy praise isn't exactly rock solid... I know you love them - but they have their weaknesses like any other engine.
