99 twins
Bought a pair of 99 twins but it has the n3c1stamped on it. I've been doing my research and It seems like they did come on those years the Jdm version how can I tell if they did come off that motor. Would the serial number be different any input works thanks

From what I have seen..
early model turbochargers are N3A1, green colored actuators. 91-94?
then came the first N3C1 94-98, still green actuators, different secondary oil return from early model
99+ spec low power turbos N3C1 gold actuators
99+ spec high power turbos N3G1 gold actuators, bolt on abradable comp covers

The N3C1's have a much higher nickel content to prevent from cracking at higher boosts. I've also heard the Japanese tuners swapping in the earlier turbos to get more power. In IMO, you won't get THAT much more power with the N3G1's vs N3C1's. I'm sure Dale Clark can chime in on this
Bit off topic but I actually have N3C1 Twins in my FD boosting 15psi and is pushing 359rwhp. A buddy of mine has the later N3G1's twins also running 15psi and is only pushing a bit more at 364rwhp... not sure if the extra price point is worth it.

The biggest effect on life expectancy is that the newer turbos generally have fewer miles on them.

Not really... I would put the N3C1 and N3G1 in the same category in terms of life expectancy concerning the cast iron parts. Both of them being slightly superior to the N3A1. The biggest effect on life expectancy is that the newer turbos generally have fewer miles on them.

My car on the 99 turbos is noticeably stronger in the mid range than before them and throttle response is exceptional. The car is over 300hp from 4250(transition to both turbos) all the way to 8k peaking just under 350 around 6500 before falling off up top down to 310 at 8k due to a few reasons, a useless intercooler being on of them(Greddy smic).
