Didnt get much back from another post.....need some advice

All the mods i have (and plan to keep it that way) on my car are a Apexi pod with cold air intake and full 3" Blitz exhaust with slpit dump/front pipe. i want to extract the best performance out of what i have as i dont plan to boost it.

Would a Apexi AFC Neo do the job, or should a just go for the Power FC?

Not sure because i only have minor mods, and most people who buy the PFC have boost, fmic etc....

Any feeback and opinions are appreciated.

id go for the PFC with a boost kit just in case you get excited you can up the boost, maybe try and buy one used.

At the moment i have an Avc-r and im happy but i have a PFC waiting to get installed hopefuly next week, ill let you know how it goes.

cheers

Akeenan - dont want to turn up the boost because im pretty happy the way everything is at the moment. My thoughts are basically; the more boost, the more problems. I think a PFC or SAFC would give it the little extra performance, mixture, fuel consumption etc...

Steve - Be sure to let me know how you go with the PFC, what changes/differences you feel

Dop3y - What kind of results did the car get? higher Kw?

We go from the otherside.

What is he going to get from a PowerFC, with his mods... that can justify the extra $500-$600?

There is no boosting, no I/C upgrade, essentially its a stock car save for en exhaust

I agree. Even boosting to the capabilities of the stock turbo you won't NEED a power fc.

But if you think you might want to mod down the track (and you probably will want to! lol), perhaps a turbo upgrade.. might be best off sending the money now on an engine management system... you'll get a little more power and a little more fuel effciency in your current set up.

I really don't think you need either though, you'll get the most out of your stock car if you get that exhaust, high flow cat and really open her up!

i believe he stated on his initial post that he already has a full exhaust...

anyway, with just those basic mods u have, a afc neo will do fine! the cost difference of a powerfc and tuning it doesnt seem worth it.

powerfc $1000 + install & tune $500 = $1500

afc neo $500 + install & tune $100 = $600

$900 difference for say a max of 5-10hp gain? u decide if its worth it..

plus afc neo looks damn sexy with the colour screen! i have one myself :D

I personally doubt weather there will be any gains with his mods and no boost, probably not even a smother power delivery. Timing will be pretty spot on std and the safc will do just as good a job of controlling fuel at those airfow levels, pfc is overkill hands down! the only time the pfc starts to make gains is when the safc starts runing out of resolution(if thats the best word to discribe it, cant be bothered typing a in depth decription) and the std ecu starts taking over playing with the timing and fuel (r&r). my guess is the pfc would start to be worthwile/show gains above the 200rwkw mark

i know when everybody gets there first 'line (ive had mine for 3 months) they say there "happy just the way it is", and then a few weeks later they start modding flat out, but im genuinly happy the way it is, but a 'smoother power delivery' is spot on in what i want to acheive, also with a little gain in power. its a bit laggy, gets about 400km to the tank and i think the piggy back or pfc will help with these issues. true?

I got 170rwkw with the current mods by the way.

oops sorry, I mis-read it!

sounds like you know what you are doing PAV just a bit of food for thought... i pretty much have a stock car... and the power delivery is second to none.. it's just been set up really well. Ignition timing advanced, fmic, boost controller, high flow cat and 3inch cat back... had a split dump pipe bu the quality wasn't the best so I put a stock dump pipe back on and it is really running perfectly.. couldn't ask for better!

Anyhow, you sound like you know what you are doing, good luck with it!

Got any pics of the new Neo tuyen?

The computer generated ones they use for marketing are pretty useless for working out how big the thing is :)

yeh just took some then in comparsion to safc2 :P

sorry for whoring your thread PAV34.

ive driven stock r34 gtt and id say getting a powerfc wont make power delivery any smoother. Trust me they are damn smooth already! (try driving r32 with rb20det haha)

The main difference with powerfc to afc neo is that pfc can adjust ignition timing as well adjusting airflow for fuel while afc neo can only do fuel. While running stock boost, adjusting ignition is not needed. But adjusting airflow would help (a bit more power = a bit more smoother?) as u have an airfilter and full turbo back exhaust which would usually cause it run a tad rich..

400km a tank is decent.. u should look into replacing the o2 sensor of the car if you havnt already. Should be replacing them every 40,000km apparently in the skyline manual.

good luck :)

thanks for the comparison of the 2 afc tuyen, any major differences, pros and cons of the 2 items?? how much did you pick up the neo for?

btw forgot to mention i have a high flow cat....i know that problaly doesnt make a dif..

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
