hey everyone

Does anyone know why my car could be kicking back and like a loud noise coming from the exhaust it just started recently so ive changed all plugs the coil pack and done a full service thinking it could be the oil which I was told but made no sense as I only run motul 300v chrono it usually happens on boost but not all the time im currently have a profec b controller and a apexi afc neo( I know its not as good as a power fc)

I have larger injectors 600c upgraded afm z32 larger fuel pump and fuel pressure regulator it seems like the car is running really rich or could it be another issue that I haven't figured out.

If anyone knows the basics of tuning an afc neo please let me know as well as I cant get a booking for a tune till mid june.

Sorry if this Is a stupid question but does + on the afc mean your increasing fuel or the air intake thanks

I can't think how it could be the oil unless having none has caused a failure.

Definitely sounds tune related. The combination you have described plus AFC Neo = monkey purple dishwasher moon dog wonder special long time. ie = it does not make sense and will not work properly.

Do not drive the car until it gets a proper tune.

ok wont do thanks so I take it the neo isn't a good choice with all those mods will I see a difference with a power fc and where is the best place in perth to tune was thinking either hyperdrive or ovaboost anyone have reviews on either of these I use to get hyperdrive to do a lot of work on my silvia and they were pretty good

yeah didn't realise the safc were really restricted to what they can do will be upgrading to a power fc and give it a full tune which should solve the problem and give me the extra power that I seem to missing with it

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up

      You have a knack for photography my friend. It makes the 86 look like a complete bucket. The 34 went with you to Europe and back. It's special. (we all feel the same about our 'shitboxes' that every bystander seems to absolutely love)
