Hmm so after some pondering ive decided to go for a S-AFC II, FMIC and fuel pump. And then in the near future hopefully a slide high flow.

From what ive read in old topics the SAFC can't really support bigger injectors, but would support a high flow yeah?

Still undecided on what pump to get, Walbro is deliciously cheap but people seem to have had issues with it. Was also going to get a Bosch 040 but aparently its crap and noisy :D

the SAFC isnt going to handle the high flow turbo very well. you'll be able to tune it slightly, but you'll be missing out on somewhere between 30 and 50rwkw from the lack of an ECU once you put a aftermarket / hiflow turbo in. Plus stock injectors cant cope with much more than ~225 rwkw.

The SAFC isnt a bad option, as it will hold its value, so when you put in an aftermarket ECU, can sell it for same price you buy it. Nothing wrong with the Bosch 040 if its installed properly. can just hear it over exhaust at idle, and you cant hear it at all once you start driving.

As i said in my previous post however, make sure you have set aside money for a clutch, especially if your still running stockers.. it aint gonna last long. might just be able to squeeze that into your 2k budget along with fmic, fuel pump and safc2.

You can always sell the safc should you want to change the ecu down the track, but it will be more than adequate for the standard hi-flow and won't loose you 30-50rwkW as stated earlier. In the dyno results thread people are running hi-flows with stock ecu and achieving 200-220rwkW, it's just a safer idea to get it tuned with the safc.

Find a genuine walbro pump with the higher L/min rating or a Denso pump from Kudos motorsport. 040's are a good pump put they're just physically to big for the r33 tank and if it's touching one side of the tank it will be noisy as hell.

When you say a walbro pump with the higher L/min rating, which one would that be? Only ones I see on ebay are the 255L/hour jobbies, the Walbro GSS 341. That the one your talking to or is there a model up from that? I WOULD like to go with the Walbro mainly because they seem easy to source and are one of the less expensive pumps around.

One is a GSS341 and the other is a GSS341HP, most dodgy traders sell people the GSS341 which is fine for standard cars, but for modified and larger capacity cars the GSS341HP(High Pressure) is required.

Sorry by l/min I mean't l/hr... brain lapse :) .

Hey not hijacking the thread but let me know how u go as i have similar mods to you and am in the same boat.. got full exhaust, boost controller and got same sorta money to play with. But i have splitfires and a h/d clutch as well:)

So the safc's are actually worth it? And i (and Lachlan33) would feel a noticeable difference with the addition of a tuned safc and a bigger fuel pump? I'm also debating whether to get a justjap or a hybrid cooler for mine.

Walbro's low pressure pump in this design is part number GSS315. GSS341 is the high pressure variant.

get swaybars and some coilovers, and maybe some castor rods if the budget can stretch that far ;)

Then you can corner faster and out run all the guys with stock suspension and 200rwkw :)

what he said, but forget castor rods :nyaanyaa: or enkei rims ;)

Whats the most important thing to you?

Is it "bling/rice'?

Is it better safety (the standard gtst needs some help with traction)?

Is it straight line accelleration?

Is it reliabillity?

Depending on how you answer these sorts of questions you will get some slightly different answers.

Remember that search is your friend.

If you are handy with a spanner the $2k goes alot further.

      What brakes on R34 GTT(Europe)

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      Duncan's V37.......race car?

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
