The 2.9L RB26 swap in place of the stock Nissan SR20 is easy to zero in on here, but it's not the modification that has made the most difference outright to lap times and driver confidence...
With the ability to get 1500hp from this setup, owner and driver Chris Kostakis shows a lot of restraint and the realities of power vs performance when circuit racing a vehicle that is continually developing along with its owner.
What are the downsides of swapping a SR20 for an RB26?
What are some advantages drive by wire (DBW) throttle control gives?
What are some key considerations of traction control for motorsport?
Does motorsport ABS really make a difference?
These questions and more are covered by Andre and Chris while they were at the Australian GTR Festival at Sydney Dragway and we look forward to seeing where Chris and his engine swapped 180SX head in the future when it comes to an aero package and time attack, although he sure has more than enough to keep a grin on his face as this car sits now!
