1987 Iroc-Z 350 planning a turbo build
I have a 1987 350 TPI Iroc-z. As the car sits it's pretty much bone stock not a thing done to it. I've been thinking I'd like to put a mild turbo setup on the engine (around 7-9 psi) What I don't know is the limits of the MAF's ability to read, how strong is the bottom end of the 350, what injectors I will need to use, is the factory fuel pump strong enough? etc any info would be a tremendous help I just want a nice daily driver with some boost. I want to note also that I am going to have my stealth ram intake installed on the 350 once I get a turbo setup and take off the old TPI upper and lower intake.

how about doing some reading rather than expecting us to do all the work for you? Everything you ask has been answered dozens of times over on this forum.

in short. no. unless your car just rolled off the assembly line with 0 miles, everything you mentioned needs to be changed. The stock bottom end will with stand 7psi maybe even 8psi max, but you'd have to have really have the air fuel on point, because one knock and its game over...
