Hey guys, I was wondering if any of you knew more detailed specs about the R390 motor. I really want to know the detailed specs on the turbos used in the car. I know it had a 9.0:1 compression ratio, which I thought was kinda high, and wondered what turbos Nissan decided to use for that high of a ratio. If you know or can direct me to someone who does, I would be greatful.

Just another Nissan fan who wants to learn.......

I, too, would like to learn this. That is why I am subscribing to this post now... Check!

Anyway, in Gran Turismo 3, the specs read that the displacement of the R390 GT1 road/race cars are both 3500cc's... Yet, I always thought the engine is 4500cc's... Whoever actually answers this long-awaited question, please inlcude something about that...

Alright, after searching for quite a while I found this: http://www.autoweb.com.au/start_90/showall_/id_NIS/doc_nis9810154/cms/news/newsarticle.html
