If you CBF doing your research, just do this:

"Stage 1" - Basics

• Turbo-Back exhaust - If you don't have one already, you can get one custom made in mild steel or get one off the shelf for around $800-$1200 for something decent.
• Intake - Debatable that you need this, a good panel filter will get you out of trouble, but if you're chasing power later replace your intake for a solid item. $250.
• Intercooler - HDI is the cheapest you should go, even then you might want to consider better. $600.
• Boost controller - A decent electronic unit. GFB G-Force II can be had for $300.

"Stage 2" - Can be done without ECU/Tune (not always best)

• Fuel Pump - Either go a Walbro 255 or 450 drop-in pump. I suggest the 450 to give you some room (I wish I did this ergh). Don't forget relay mod. $200-$250,
• Turbo - Lots of choices, most suggest a Hypergear high flow for a drop-in replacement. That's around $1000. Or get their ATR replacement turbo for $1200. Keep boost < 10psi at this stage with these turbos.

"Stage 3" - ECU and Tune needed

• ECU - Nistune is a cost-effective solution. Get yourself an RB20DET Manual ECU, get yourself a Nistune board with feature pack, go get it tuned. Guessing $1000-$1200 all up.
• Injectors - Nismo 740s are a good drop-in replacement, but most would suggest going a top-feed setup for cheaper parts and more choices. Both are $1000-$1200.
• AFM - Get a genuine Z32 AFM. There are other choices but this is tried and true. $300ish.
• Splitfires - Not always needed but generally recommended at this level. $500.

"Stage 3.5" - E85

• As part of "Stage 3" mods. get an ethanol flex sensor and tune everything for E85. $290 for sensor and harness.

 

If you did all of this it would cost you around $6-7k or $4-5k if you already have the basics and will net you 250rwkw on P98 or 300rwkw on E85. Nowhere was a throttle body mentioned (because you don't need one). This is a good list to go by, but keep in mind other things you may need along the way. A good example is a fuel pressure reg, that might be needed by Stage 3.

Do not attempt any of this unless your car is in tip-top shape and is well serviced.

Although not gospel. this list is proven time and time again. Follow it for proven results with less headache (and heartache) in the future.

Great post.

Looks like with the infinity the Nissan  cas is supported with no additional work!

Any one run or have experience with the Aem Infinity Ecu. I have one in my garage from my last project car. I cant justify spending a bunch on a power fc if the infinity will work. 

 

I will be running it on a r32 gtr.

 

Also when is a good time to throw a tune on the car. I will be putting full exhaust and intake on soon. No boost restrictor is in place either.
