what other mods, would i need? i know i forgot to list injector. i want reliablity. im looking to use it as a autocross car. i already have coilovers (tein). i wil be upgrading brakes to 5 lug and 300zx 4pots. i appreciate all the info.

 

Ok, im going to compile a list, not all of the parts are a must, but definately would help, especially if your gona autox the car, then taking care of the car is a must

Must have for a good 300hp:
1. One of the turbos stated above or another similar too them.
2. 550cc+ injectors
3. z32 maf
4. tuning component(ie safc) with a good tune
5. 3in. downpipe/exhaust
6. Stage 2 or 3 clutch
7. FMIC
8. Walbro 255 or better fuel pump and z32 filter
9. Metal Headgasket
10. Boost controller
11. Cams not necessary but would help some
12. Turbo manifold/outlet not necessary but would help with spool time.
13. BOV

Things not necessary for 300hp but definately would help the car and prolong the life:

1. Nismo thermostat
2. Bigger radiator
3. Electric fans
4. turbo timer

than of course your suspension components are necessary and little things would always help like lightened flywheel, gauges, good tires/wheels and so on if the car is going to be ran hard. There is probably more stuff that i am forgetting at the moment but you get the gyst(??) of things,

 

Hell ya im still laughing. I remember a kid how ran 19psi on is sr.

I remember when it popped like a mother. I laughed my *** off that day when i told him to turn down the boost.

**** 17psi is a lot to take on stock SR.

But what do i know i eat my own poop.

 

9...Not neccessary, but recomended
10... you can run a manual boost controller or rely on your wastegate (definately get a boost gauge)

other than that, i completely agree with the list above (im bored so i changed a few little things haha)

 

any thing above 16 psi on the t25 and you go past the efficancy range of the compressor and actually start to hurt preformance

 

9. I agree but u will never reach 300hp without it

10. manual boost w/ a gauge would work, but relying on the wastegate will never get you to 300hp either

me too
