Simon, tricky to set up I believe and what is wrong with the normal power fc?

Pete has good hp and excellent driveability with the normal one using Z32 afm's.

I would suggest that if you want the no AFM route , use Autronic, or heaven forbid..wolf. Just be prepared to pay for the tuning on the latter... :D

Simon, also consider the fact that the Datalogit software used in some shops may not support the D-Jetro.. I cannot get my PFC Pro tuned anywhere on Datalogit for the same reason... If you're happy to tune via h/c and want launch control I'll do ya a swap for a standard PFC... I believe R32 and R33 GTR PFC's are interchangable.. :D

i recommend you stick with the afm and ditch the map sensor idea... its a much more accurate way of measuring the mass of air coming in. drive-ability will suffer if you switch to a map sensor - and you will need a retune for any changes to the engine if your running a map sensor

I'm very interested to know about Power FC djetro also as I have noticed from the photos of my GTR that it does not have afm's. I would suspect it's running a map based ecu such as HKS FCON? The cost of buying 2 afm's and a std power fc would far outweigh the cost of a djetro unit....

540 isnt enough :)

$760-780 for two knew z32 afms with plugs from repco, not sure on there limit

(they read about 4v at 530rwhp so plenty of range left) but if your playing in this ball park then money should not be your issue as you will be spending sh.. loads on everything else anyway

ie clutch, gearbox, internals, fuel system etc etc

But you would need a retune if you changed something anyway. even with afm power fc.

not quite, say you take down the boost pressure, or change the boost controller arrangement ie wastegate creep control, then on a map based car it will need a retune

whereas on an afm based engine, it measures mass of air directly with the afm and thus knows if boost has been changed etc..

of course any big changes and you will need a retune on a afm based car as well..

but the big point is afms will give a better tune then map sensors, as they are more accurate in measuring the air coming in, i agree with what pnblight has said, stick with either twin z32's or rb25 afms :)

$2k deal for engine management sounds like a steal to me ,as ecu and air/fuel control is everything if your trying for 540 plus rwhp i would be spending some series money on management and not looking to cut corners ,especially if you want this car street drivable

i think you will find alot of tuners would tell you to spend the money on management over many other thing first

but this is only my opinion and i have had great results with my pfc and afms, went you get the right guys tuning (Lumpy is the man for pfc)

IIRC the Apex PFC weak point is not being able to work with d-jetro...not sure on the Apexi Pro version.

Regarding the F-Con V Pro it's not a problem thus tuners' choice. Not sure on the F-Con SZ/SA...but I think it can also run d-jetro as it can be converted to a full-com but don't quote me on it. My December Option issue has gone walkies...but there is a comparison in there outlining the strong and weak points of all the Japanese CPUs. F-Con V Pro obviously wins out right as the best, but question I ask many is do you really need something like a F-Con V Pro, unless your after 600ps+!

Theres a few others i know of who can tune power fc just as well. cheers.

Hi there, Tuning an F-Con V Pro in Perth is a problem as we do not have someone here that is capable at present, thus my intention to get rid of the F-Con CPU. In a quest for saving a few dollars I considered in the light of not having AFM's it might be cheaper to seek out a MAP based ECU to replace the F-Con with that can be tuned locally. I'll be happy with a clean 400rwhp, so MAP sensors are not a necessity.

Looks like I might just have to fork out for z32 afm's and a std Power FC...

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.

      Regardless of neglect or incompetence, fixing either is tedious and annoying. Most of the neglect on my car is definitely rust. I hope I can at least pass inspections later on and they won't fail the car due to slightly corroded hardlines. I was generous with rust converter and wax and it looks ok, most lines in the rear are hard to see properly anyways.  Definitely will test them though to make sure they don't rupture under pressure, in that case the car isn't going anywhere this year.
