Its time to upgrade, nothing to expensive, im looking at a second hand HKS 2530,2535 or a Power FC. Im sure the turbo is going to give me the best bang for buck results so im thinking this way at the moment.

I tune the car myself via the SAFC2, and last dyno tune we where pushing out 207rwkw running max boost (13psi) out of a stock turbo. Any more boost and it wasnt a smooth power curve. With the Power FC, i dont think i will be able to get much more peak power, probably a bit more meat in the middle. I noticed a slight dip at 6000rpm in the power curve which we couldnt get out. Ive noticed this on a few other dyno graphs as well with R33's, must be the stock ECU.

I think with a small HKS, we should be able to see 230/240rwkw comfortably even without a Power FC.

Any thoughts?

i'm pretty much in the same boast as you ...

s2, gts-t, with turbo back 3", hks pod, hks boost control ..

my mod list is as follows, for reasons i'll explain

1. power fc - not installed yet, on the way from japan

2. fmic - about to order

2. fuel pump - ordered

3. regulator - researching

4. afm (z32) - waiting till i find a decent priced one

5. turbo or injectors (high flow) - (sigh) expensive

6. injectors or turbo (high flow) - as above

the reaon i am doing it in this order is that i want all the support systems of the engine to be fully up to spec before i go winding up the boost to 'crazy ass levels'

with a 'phat, fully sick man' turbo ... the last thing i want is a melted piston due to the fuel pump maxing / dying or other such sillyness ...

just my 2 pence worth

(i'm a pom, so am still allowed to spend my opinion in £)

How's your current turbo doing dude?

If it's on its way out, easy :) get the bigger turbo. Use the SAFC to lean things out. Then get the Power FC.

If not, I dunno. Personally I think I'd get the computer first.

      I'll probably be putting the shit box back on the dyno again soon, I want to dial in the closed loop boost control properly. I'll have a camera facing the car/motor for fun too. Just note, there are essentially 3x 10AN inlets going into the catch can and 1x going back to the intake pipe. Most of the time the catch can "return" to the sump actually is the crank case breather, pushing air out.

      I have the R3C with a Nismo slave and by no means does it behave like a stocker, it ain’t THAT bad. On take off just give a bit more throttle than you would say a coppermix and it’s fine. It will not slip though.

      Yet another RB Neo misfiring thread after reading all the others.

      Okay. Final round of testing done. Got a friend to hook up a fancy scanner to the car and we also ran some compression and leakdown tests, she is healthy.  The MAF was definitely the culprit. So for future reference anyone with similar issues that find this thread. I suggest the following steps, in order of affordability:   Check your spark plugs for any fouling, replace plugs if they are bad or re adjust the gaps making it narrower (0.8mm would be good). Check every coil's resistance with a multimeter. It can be done by probing the IB and G pins on the coil pack. Resistance should be around 1.4 (+/- 0.1) Ohms Check the MAF. If you have Nissan connect or a good scanner with the 14 adapter it should allow you to see the voltage on the MAF reading should be around 1.1 - 1.2V when car is idling. But if you don't, buy a new MAF from Amazon and test, then return it. (For instance, I got a Chinese one for $40 that was reporting 1.3v on idle). If you still have scanner, you can run tests on the injectors to see if they are working, just remember to unplug the fuel pump fuse/relay and have no pressure on the line. Then listen for the noises that the injectors make. Clean/replace injectors as needed. Once you find the issue and fix, order thousands of dollars worth of OEM parts to refresh unrelated things (Optional)   PS: Thanks to the absolute legends of this forum for the responses and help to someone that went a bit over their head.
