There was some d**k who was claiming he had the fastest one, I laughed because I could probably beat him without a sweat. It was diesel by the way lel. All stickered up and standard interior....Don't know where the thread is gone, I was trying to search for it but it happen before the site hacking. Probably burried somewhere (there was a video).
Anyway, I've been following your build. I really enjoyed the choice you made in engine swap, although I feel the TU5JP4 is capable if you are willing to invest your time and money with some cam work, individual throttle bodes, stand alone ECU..etc.
I take it the engine you have in yours is the XU10J4RS correct? If so you have the fastest one definitely heh. Instead of wasting money on Nurburgring which is expensive and overrated, why not book it into some local car clubs for a time trial, personally I think you will have more fun doing that. The weight advantage is what puts to shame a lot of other cars when I end up having fun on the B roads. The lack of understeer in these things is quiet nice, having a nice neutral steer for a FWD. Tracks or straight roads is not where our vans belong, despite the excellent power to weight ratio
I forgot to add the biggest engine conversion i have seen on here is a 3.0 v6 from a 406 coupe. I think he sold it. Car has been going round ebay a few times. Question is can you live with 20mpg hehe
