Hi guys,

I would appreciate some advice from experienced owners.

Basically i just purchased a Apexi PFC as a base for all mods I want to know if there is anything else i might as well do prior to getting the Pfc tuned.

I have a standard R33 minor mods list as follows.

Cat back exhaust

Front mount cooler

Boost controller

Im currently in the market for a Bell mouth dump pipe and front pipe and cat.

Should i bother with a bigger fuel pump or will standard cope with a higher boost setting?

As above said I want to know if there is anything else i might as well do prior to getting the Pfc tuned and squeezing the most Kilowatts out without swapping turbo as yet.

Any PFC Tuners people have had a good experience with I dont mind paying if the work is worth it?

  • new panel air filter for std airbox or pod enclosure with cold air feed
  • dump and front pipe a must
  • check coil packs for any visual damage or cracks
  • boost gauge if not running PFC boost kit

In regards to standard airbox ever since i installed the front mount i cant get the cold air snorkel back on the air box because of the top pipe so i bought a pod need to source enclosure

Make sure the fuel pressure is monitored while you are boosting it up and tuning. And be prepared to buy a new 040 or equivalent if the pump shows any sign of not being able to keep up. Don't wait for it to fail, but there's no need to spend the coin immediately if it is OK.

That said, if it is the original pump, then it is running on the borrowed time part of its life, so a pre-emptive change out is not silly.

Go find someone with identical mods, copy their map, go find a tuner and get the A/F ratios and ignition tidied up (if needed) so they charge you less.

So many times, I've seen people fork out up to $1k for a "so called" tune from scratch, when most of the time it's a copy and paste job.

I recommend you highflow the turbo before hitting the dyno. Your stock turbo is just going to f*ck out once you up the boost.

The following should be done and can be expected (not taking into consideration your current mods):

JJR bellmouth front/dump

3" highflow cat

3" cat back

Hypergear highflow turbo

FMIC

Walbro fuel pump

Provided all other aspects of the car are in good condition you should get 220-230rwkw without changing the stock injectors or AFM @ 15 psi.

I have read that the stock injectors are not as great above that pressure level and it is known that is already the limit of your stock AFM. Personally I would run the above setup if wanting a quick car not exceeding 250rwkw.

ok so 040 internal pump is a must cheers!

Definately change the pump.

Where are u located?

I'm located in Western Sydney

I haven't gotten a quote for a tune as yet. although saving money and tuning time would be ideal!! is this a difficult process copying maps is it as simple as changing settings via the controller

The high-flow does have a nice ring to it i might have to wait an extra week to come up with more funds and look for one on the forum.

Dont mean to start a debate which fuel pump is better "Bosch 040" or Walbro 400lp both intank?

Thanks guys.

Hard to avoid starting a debate on that one. I went with the Bosch pump, mounted in tank it is the loudest thing in my car. But I'm reasonably confident it won't just up and shit itself. Walbros are quieter, but the internet derived failure statistics on them are not as comforting. Horses for courses there I'm afraid.

I dont mind Fuel pump noise lets me know its working at least.

you will need a FC Datalogit Kit, just borrow someone's kit, the rest is piss easy

If anyone can help me with this I will be more than happy to pay for there time in cash or beer currency goes in both!!

I actually sold mine a while ago when I "thought" I got out of the car scene. Speak to DVS Jes, I'm assuming he's a good honest tuner from what he shares on the forum.

If you ever go anything else like Adaptronic or Vipec you don't need an extra box to connect it up to a laptop. I got a mate that can get Adaptronic ECUs much cheaper than most stores.

BTW, just get a Nismo drop in fuel pump, less headache in the long run, less noise, no fuel starvation problems, no dying fuel pumps, no worrying about fake yumcha spec Walbros.

Bosch 040 will be fine and cheaper for your needs

Just bought one! thanks for the advice boys!

I can tune it if u want buddy. Will do u a competitive price too.

DVS JEZ you have PM

how come no one mentioned the deatchworks pump, theres a 300LP/H one thats under $200, if you decide to go for more power later you wont have to buy another pump,

When i got my power fc tuned at the same stage , they had to replace

*Coil packs

*Dump inadequate

* Fuel pump

* plugs

*Clutch

    • Hey y'all! I'm curious about how y'all go about widebodying your cars. I noticed that when running a square setup, my front wheels are a bit more tucked in than my rear wheels. Not by much, maybe 5-10mm. This leads me to wonder - when I widebody, should I use narrower front flares and wider rear flares? I found a set of 40mm rear flares that I really like, and was thinking of pairing them with some 18mm front flares, but I don't want the car to look strange. How have others done this? Note, I'm in a sedan. Thanks!
    • And if it was anything other than an auto tranny part, it might be a problem. But seeing as all auto trannies belong in the recycling bin, it's fine.
    • I have an R32 Fenix rad. It is good.
    • All the schemas I can see, indicate your typical setup of ATF 'cooler' (read: heat exchanger) in the bottom radiator tank..ie; https://nissan.epc-data.com/stagea/wgnc34/5413-rb25det/engine/214/ ...but I can prattle on a bit here. These trannies have a thermistor in the sump ~ the TCU reads this and 1. bumps the line pressure up when the ATF is 'cold' and 2. prevents the TC lockup clutch from operating, until the ATF comes up to minimum operating temp (keeps the ATF 'churning' through the TC so it heats up quicker) -- trigger point is around 55C. In these conditions, the engine coolant temperature rises faster than the ATF temperature, and also helps heat the ATF up, which is why it's best to think of the in radiator tank setup as a heat exchanger ; the heat can flow in both directions... ...with these trannies, the 'hot' ATF comes out the front banjo bolt, flows through the cooler/heat exchanger, and returns to the box  via the rear banjo bolt. This gets a mention, due to the wildly different opinions wrt running auto trans fluid coolers ~ do you bypass the in radiator tank altogether, or put the cooler inline with the in radiator tank system...and then, do you put the additional cooler before of after the in radiator tank system?... ....fact is the nominal engine operating temp (roughly 75C), happens to be the ideal temperature for the ATF used in these trannies as well (no surprises there), so for the in radiator tank system to actually 'cool' the ATF, the ATF temp has to be hotter than that...lets say 100C -- you've got 25C of 'excess' heat, (slowly) pumping into the 75C coolant. This part of the equation changes drastically, when you've got 100C ATF flowing through an air cooled radiator ; you can move a lot more excess heat, faster ~ it is possible to cool the ATF 'too much' as it were...(climate matters a lot)... ...in an 'ideal' setup, what you're really trying to control here, is flash heating of the ATF, primarily produced by the TC interface. In a perfect world, wrt auto trans oil cooling, you want a dedicated trans cooler with builtin thermostatic valving - they exist. These should be run inline and before the in radiator tank system ~ when 'cold' the valving bypasses the fin stack, allowing the ATF to flow direct to the in radiator tank heat exchanger, so it works 'as intended' with helping heat the ATF up. When 'hot' (iirc it was 50C threshold), the valving shuts forcing the ATF through the cooler fin stack, and onto the in radiator tank heat exchanger...and you sort of think of it as a 'thermal conditioner' of sorts...ie; if you did cool your ATF down to 65C, the coolant will add a little heat, otherwise it works as intended... ...the 'hot' ATF coming from the front bango bolt, is instantiated from the TC when in use, so all/any flash heated oil, flows to the fluid-to-air cooler first, and because of the greater heat differential, you can get rid of this heat fast. Just how big (BTU/h) this cooler needs to be to effectively dissipate this TC flash heat, is the charm...too many variables to discuss here, but I just wanted to point out the nitty-gritty of automatic trans fluid coolers ~ they're a different beastie to what most ppl think of when considering an 'oil cooler'... /3.5cents   
    • Been a busy but productive day. Axle and hubs acquired. All fitted up after a bit of modifying. Need to sort out wider mudguards and running light reflector covers but other than that the trailer is gooood to go !!
