GTX35 nitrous S15 vs Nismo twin turbo GTR in south Korea
Went to Seoul/Incheon last month to tune a couple cars, long story short the S15 wasn't ready so i spent a week fabricating some exhaust and then putting it all together :P
S15 Silvia Power FC speed density tuned with Datalogit
stock bore CP pistons (stock compression)
manley H beam
ACL bearing WPC coated
264 cams (need to be changed to 272 or 280* easily another 50 HP)
Velocity Element Vband turbo manifold with Tial MVR
GTX3582R .63ar turbine (small for this size turbine wheel)
stock intake manifold (30-40 HP available with Velocity Element intake manifold)
R34 GTR HKS Fcon
The owner of the car said the motor had forged pistons and the turbos were supposed to be Nismo units. With out any way to get the proper history of the car I pulled the injectors to check the part # and re gaped the spark plugs before doing a boost leak test. Unfortunately the injectors were only 555cc so i knew we would be limited on how much boost I could get before maxing out the injector duty cycle.
Check out the full article for all the details, more pictures and videos of the cars in action. GTX35R SR20det 30psi with nitrous VS twin turbo GTR
Video of the S15 on the Dyno ***I did not love the fact the dyno room was serving as a giant EGR system... Not safe at all.***

Looks like i'll be making another trip out to Seoul and Incheon South Korea within the next couple months, anyone here on EVOm out in Korea? Always fun to meet up for a drink or food in foreign land!
