I have currently done up my R34 GTT with these mods I have listed below. Need advice on what other essential parts I need to get before i proceed on to the next level of upgrades. For now, I just want it to be done up till the stage where the ECU comes in and is dyno tuned. Parts list:

- Blitz FMIC

- HKS BOV

- Greddy BC

- Dump Pipe

- Metal Cat 100cell (To be installed)

- HKS Exhaust

- Fuel Pump & Fuel Regulator (To be installed)

- HKS Pod Filter

- HKS Coilovers

- Race Clutch (Brand unknown)

- ECU (To be bought and installed)

If there are other essential and important parts that need to be installed up to this point, please do let me know. thanks!

i would get a ecu i reccomend a power fc or vipec and also get yourself a turbotech boost controller or a EBC. get it tuned and up the boost to a safe level for the stock turbo. then when your ready to upgrade the turbo choose the turbo to suit your power goal and get injectors and Z32 afm to suit then you should be set

WHY?! WHY?! WHY?! WHY?!

Sell it and put it towards the ECU.

Sell the fuel reg. bov and pod (get a high flow panel filter for your stock airbox) and get a Nistune, PFC or Vipec ecu.

Posted Yesterday, 06:55 PM from the Stagea section (S2 Stagea same engine as GTT - stock fuel reg, bov and airbox):

3" turbo back, k&n panel filter, 10psi = 135kW

Nistune, 11psi = 175kW

Pretty happy with that. Much smoother power delivery too.

nistune all the way

1. As above get a nistune installed, as good as aftermarket, looks stock (chip in your ecu), is cheap and everyone can tune them, find a good tuner, if in VIC I highly recommend STATUS, if in SA I recommend Boostworx

2. Sell the fuel reg as its completely unnecessary, makes tuning difficult and the stock one is ample for 300kw+

3. Sell the pod and get highflow panel filter as pods suck due to heat soak.

4. Get good tyres, I recommend federal 595evo/rpm for cheap performance

5. Get proper rated springs in your susp for aussie roads, no doubt HKS are 8kg or something stupid, aim for 4-5kg max for aussie roads, Tein super street are much better, or for the legal stock look go bilstein shocks and whiteline springs (will pass defect inspection if legal height)

This will be good for ~200kw ish with good streetable handling.

Future mods:

Get GTR injectors or equiv, Z32 AFM and a highflow turbo for the stock look that makes 250kw and will pass an EPA/defect inspection, if you don't care about getting defected and looking stock look towards a GT3076 turbo and make ~300kw

I just got the BOV brand new. Its a HKS SQV3. Sell it? Really? i was gonna get the plump back adapter for it. =(

Really? Fuel regulator is useless? THe mechanic that did my car told me its better to get one, with a gauge. Hmmm will consider that again.

How much roughly is a Highflow panel filter?

Ask yourself this why do you need an aftermarket fuel regulator? Can your current pump + reg + injectors supply enough fuel?

Yes? then why upgrade? (requires retune, shiny and will earn you a defect, harder to tune, often less reliable than stock)

No? then why not upgrade injectors? upping the rail reg will ruin your spray pattern making economy worse and you could have just put the money towards injectors

Highflow panel filter will be similar if not slightly cheaper than a pod, it is also completely street legal, avoids heat soak and will result in better performance and avoid defects. It will also sound similar (a bit quieter) and flow just as well, but whilst avoiding heat soak issues, win win.

Have a read of the nistune website. It lists a number of WA installers:

http://www.nistune.com/ordering-distributors.php

Also read the nistune thread on here.

The panel filters are a common size - falcon, evo etc.

I m using a Pipercross Px-PP1128 for about $100 there are K&N many others.

Use the search button and use Google to ask questions (quite often you will be referred to this website!).

Best option is to email nistune themselves, pete (one of the nistune manafactureres) whos email is: pl@plmsdevelopments.com will be able to recommend the best nistune tuner in your state, he is a very knowledgeable and helpful guy so I'd definitely swing him an email and see what he has to say.

Agree - get a Nistune, I just did, and cant be happier - they cannot defect you for that as its hidden in the stock ecu box itself, dump that fuel regulator - theres no need for that, and yes the fuel pump IS important, just make sure to get it rewired, see threads in SAU for this - get the Walbro GSS342 pump.

Boost - I have mine at 12psi - dunno if I shud go 13psi?? - I know 14psi is the limit for stock turbo. I also just ordered a loboka (bokka) 4inch body 100 cell metal cat from ebay with 3" pipe entry / exit points.

And you're set. Turbo - I think I would go the Hypergear atr43 series turbos - maintains the stock look and no need for extras like oil/water lines, dump, custom intake, as is required with garret turbos - plus these also make similar power - I have yet to sit in a car with one before I decide to get it

I'm starting to loose count how many times i've posted this block of text lol.

The only reason to "upgrade" the factory FPR is really in three instances:

1. When your injectors are starting to max out, but you don't want to upgrade them, so you bump up the rail pressure with the aftermarket adjustable fuel pressure regulator to push them a little but furthur. Obviously this isn't ideal and most people don't recommend it. Just buy the correct injectors to start with.

2. When you are running huge amounts of boost and the factory fuel pressure regulator can not keep up the 1:1 fuel pressure ratio. Therefore you will need an aftermarket fuel pressure regulator that can handle this high amount of boost pressure and keep up the 1:1 ratio.

3. The factory fuel pressure regulator has failed so you may choose to buy an aftermarket one however still run it at factory fuel pressure.

So as you can see, not many people fall into the second category because a lot of people don't run 2+bar of boost through their car. A few do fall into the first category because they may be on a budget and don't want to upgrade the stock injectors so they choose to bump the rail pressure up instead and obviously a few will fall into the third category.

However there is a fourth category that you will find 90% of people with aftermarket fuel pressure regulators fall into:

4. They have no idea what an adjustable fuel pressure regulator does, but they got told to buy one by a mate or read about one somewhere.

Your mod list is good, all of the above sounds decent. Ditch the FPR as stated.

Nistune the ECU, ditch the BOV for the stock item (trust everone on this) and do something about your turbo.

Without changing your injectors and AFM you are limited to about 230rwkw, hypergear should be able to do a highflow for this kind of application for about a grand. If you want more than this you will need injectors and an AFM (add 1000 for used parts or 1500 for new parts). Then hypergear can also sort you out highflows up to 300 kw (but add lag for every interval of 40kw) that will bolt on. I recommend doing the AFM atleast and shoot for 240rwkw from a highflow using all stock housings.

    • Bit of an update to this one. Having some issues on the dyno that held us back (boost spiking) and I want to pass some info over you guys and see what you think is wrong with my setup. The current readout on this dyno is 462rwkw on a low reading dyno so keep in mind it is a real world 500rwkw setup on a hub dyno. Don't read into the power figure too much as a sign of the issue. The short and curly of it is: 2.8 Litre Racepace build RB25 NEO N/A Head with VCT (internally standard however ) Borgwarner EFR 8474  Turbosmart 50mm Straight Gate + Mac valve 6Boost Manifold 4" dump to full 4" exhaust (nil restrictions) Wastegate plumbed back in and all angles in the exhaust system are acceptable and not too sharp. GFB SV52 BOV in cooler piping  Turbosmart BOV in EFR Housing   The issue we are having is it comes onto full boost for example at 4000rpm and spikes to 24/25psi, before dropping down to 17psi before slowly rising back up to the target boost of 23psi. It was extremely uncontrollable and the tuner actually had to ramp in boost progrssively with each 1000rpm on each boost setting we selected to try and reduce the amount of spiking. Sometimes we would see a drop of 10psi from the peak at the beginning of the run, to the low, until it took the next 500-1000rpm to stabilise back up to the target boost. The tuner is pretty confident that the straight gate is just a poorly designed product and leaks too much boost upon cracking the gate open and theres no way to fix it other than going to a poppet valve. He's also confient theres no ignition breakdown or floating valves. The fueling is extremely stable as well. Turbo speed is somewhere around the 109,000rpm area. The spanner in the works for me is that prior to this Borgwarner and StraightGate, the car was tuned on -5 twins at a diferent tuner, and he also had issues controlling the boost with it spiking around the same rpm range, so to me this sounds like the same issue and it can't be anything on the turbo side as this was all changed and I think the behaviour is extremely similar, if not the same. We also removed the mac valve and did a run on wastegate pressure and it still spiked and had the same behaviour. My thoughts on possibilities are: Boost Leak VCT Cam Gear isn't reliably activating consistently - (On this however, we did a run with the VCT disabled and the boost still spiked) Turbosmart BOV is not handling the boost? However this seems unlikely to not be able to handle 20psi. I have a couple of logs that I can't make sense of if anybody knows how to read them and can obtain further logs of other parameters if they are not enough, happy to pay for anyones time. The dyno readout with the power figure is the most recent last week. The other picture is from two weeks prior to that where we couldn't break 400kw (we removed the cat), however the issue of the boost control persisted. @Lithium @Piggaz @burn4005 @GTSBoy @discopotato03 I've tagged those that were quite active in recent pages here, no disrespect to those that know turbos well but I missed tagging. Cheers 
    • I recently purchased a 2018 Infiniti Q60, which has an SD card navigation map. I can see my system has options for real time traffic updates etc, and am wondering if there is something I can purchase to get this working? I can see there are at least updated maps for USA and Canada, but nothing for Australia. Surely Infiniti took changing road systems and city expansions into account when they decided to use an inbuilt navigation over Android Auto/Apple Car Play, or are we doomed to drive on streets that don't exist in the navigation system if you drive to a new area?
    • Luckily I didn't put in etch primer as I just found out it's not compatible with my body filler lol. Also just need to sand the panel anywhere between 150-400 grit so I'm in the clear there. It does say to not apply to soft old paint, I assume that means paint that is flaking, peeling,etc
    • @dbm7 and @GTSBoy thank you both very much! will give that a shot!
