Hi, I want to put a turbo on my D15b7. How much psi is safe? And what turbo is good for me to use. Like is a t3 ok or what should I use I want to make a junk yard turbo setup and preferably a oil cooled only or water cooled only not both. Wich turbo should I get and can I even put a turbo on this motor. There is no internal work done to the motor. But does have alot of bolt on parts.All I am looking to do is beat a few friends so I dont have to go overboard. Please let me know. I do plant to replace the rods and pistons and port and polish the head with a aftermarket cam but that is way done the road. I am NOT going to swap and I already know most people say I am wasting time and money but I dont care I would rather waste more money than to swap. Thanks.
