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.

In regards to the relay mod for the fuel pump, would this do?

Just letting you know I did nearly everything in the list :) 

On the way to the airport to get the new turbo the old turbo crapped out so we put the new turbo in.
My Z32 MAF arrived and I went to hook that up but fried the ECU - 3 hours later put in a tuned Nismo ECU.

The previous owner put wire around a fuse so it wouldnt blow which may have caused the old ECU to pop. The fuel pump is on its way and all thats left is the Splitfires and figuring out how to wire up the Z32 MAF.. I got a diagram but im so afraid after frying the ECU that I dont want to hook it up.

Its been a while now but here is the list of things ive done

1. Walbro 255 fuel pump

2. TD06 Turbo (about to be upgraded again)

3. Fuel Pressure Regulator

4. Air Intake Manifold

5. changed intercooler

6. Apexi FC

7. larger piping from downpipe

8. injectors i had were 740cc but were replaced with i think 440cc or 600cc (which has made my life hell)

9. apexi clutch

10. piping

put it on the dyno and hit 311 with stock MAF. I have a z32 maf but last time i wired it up it blew up the ecu so im a bit afraid to install it.

I have a new turbo and exhaust manifold ready to deploy. looking to push 450HP

      Mistakes were made, my R34 Story

      By MBS206 · Posted

      I agree with everything else, except (and I'm rethinking this as it wasn't setup how my brain first though) if the sensor is at the end of a hose which is how it has been recommended to isolate it from vibrations, then if that line had a small hole in, I could foresee potentially (not a fluid dynamic specialist) the ability for it to see a lower pressure at the sensor. But thinking through, said sensor was in the actual block, HOWEVER it was also the sensor itself that broke, so oil pressure may not have been fully reaching the sensor still. So I'm still in my same theory.   However, I 100% would be saying COOL THE OIL DOWN if it's at 125c. That would be an epic concern of mine.   Im now thinking as you did Brad that the knock detection is likely due to the bearings giving a bit more noise as pressure dropped away. Kinkstah, drop your oil, and get a sample of it (as you're draining it) and send it off for analysis.

      I myself AM TOTALLY UNPREPARED TO BELIEVE that the load is higher on the track than on the dyno. If it is not happening on the dyno, I cannot see it happening on the track. The difference you are seeing is because it is hot on the track, and I am pretty sure your tuner is not belting the crap out of it on teh dyno when it starts to get hot. The only way that being hot on the track can lead to real ping, that I can think of, is if you are getting more oil (from mist in the inlet tract, or going up past the oil control rings) reducing the effective octane rating of the fuel and causing ping that way. Yeah, nah. Look at this graph which I will helpfully show you zoomed back in. As an engineer, I look at the difference in viscocity at (in your case, 125°C) and say "they're all the same number". Even though those lines are not completely collapsed down onto each other, the oil grades you are talking about (40, 50 and 60) are teh top three lines (150, 220 and 320) and as far as I am concerned, there is not enough difference between them at that temperature to be meaningful. The viscosity of 60 at 125°C is teh same as 40 at 100°C. You should not operate it under high load at high temperature. That is purely because the only way they can achieve their emissions numbers is with thin-arse oil in it, so they have to tell you to put thin oil in it for the street. They know that no-one can drive the car & engine hard enough on the street to reach the operating regime that demands the actual correct oil that the engine needs on the track. And so they tell you to put that oil in for the track. Find a way to get more air into it, or, more likely, out of it. Or add a water spray for when it's hot. Or something.   As to the leak --- a small leak that cannot cause near catastrophic volume loss in a few seconds cannot cause a low pressure condition in the engine. If the leak is large enough to drop oil pressure, then you will only get one or two shots at it before the sump is drained.

      Help! Leak coming under transmission

      By GTSBoy · Posted

      So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
