Hey jzx, thanks for taking the time to respond back. They are definitely not stock turbos. I bought them from Z1 Motorsports a while back. They said they were equivalent to the JWT Sport 500's. The boost is set to 15psi.
Would you still recommend the Nismo 740's for turbos of that size?
I really just want to start driving this car again without spending a ton of money...May upgrade the intercoolers later on down the road.
