Re: vs nissian silvia
found the specs for a stock sr20 det:
Here are some basic SR20DET specs showing the differences between the S13, S14 and S15 engines. There have been basically 3 generations of the SR20DET. Which one is better, it doesn't really matter, especially since there are very few engines out there that will be left stock for very long. Most customers will install them as stock as possible, but will soon upgrade fuel, turbo, intake, and intercooler, if they have not done so already when they order a conversion package.

The stock turbo will be safe to 13-15 psi. After that, the turbo is past its efficiency range, and power increases will fall off and are not worth the risk of turbo damage. The engine should produce 230-250 RWHP at safe boost.
i got all the info from drift connection.com so if that truley all the horsepower and torque at 7 psi which is what it set at with it stripped down i think i can take him.
