Hey, im looking to up the horsepower of my 300zx turbo 1988. im looking to try and get around 300whp to start with. what would be a good list of mods to start with?
What i have so far:
JWT cams
3in side exit true duel exhaust (no muffler or cat)
custom air intake
HKS blow off valve
I also want to raise the boost what is a safe level a stock engine can handle?
it has 91,231 miles on it.
I ran 16 psi on an engine with an indicated 167,000 miles on it, into the high 13s with an open diff and crappy tires. If you want to safely run that much boost, you need to invest in an intercooler, a Z32/R32-R33 fuel pump, and some bigger injectors and an injector controller or an ECU. Yours being a 1988, you'll also need a bigger turbo. Yours came with a T25 stock, the pre-88s came with the bigger T3.
You don't even really need the cams yet, and they are kind of expensive.

^agreed. Cams are great, but I'd put them towards the bottom of your mods list.

Well then, I would look at an intercooler and better fuel stuff, (injectors, pump, etc.)

Why do you think you need a dual exhaust? You do realize there is only one turbo, right?

You are taking a single exhaust and splitting it. It does nothing for performance. How do you know what it sounds like? The sound is mostly determined by the muffler used.

True dual exhaust would look silly on a Z31 anyway. There's the cutout on one side in the back, and if you go out through the side in front of the rear wheel you're seriously cutting down on your ground clearance. Simple speed bumps would kill your pipes. You'd have to use a super wide low profile exit pipe and that would just look super tacky.
A single 3" turbo-back pipe is quite fine for that 3.0 engine. I'd do a twin tip muffler, though, looks much nicer than a single 3" outlet.
