My build is almost there ! Just need your help please !

alright guys I am new to sau. I am the new guy from the u.s I posted in the n00b section . 

Anywho .. 

So my car 96' bcnr33 , is running rich as f-word 

i am running a step up on the turbos ..

i am told by pureturbos.com when I sent them there to be rebuilt thinking it had garret  2860's that I actually had a set of journal bearing nismo/garret turbos that will flow ~375hp each so when I got them back I ported stock exhaust manifolds and bolted it all together.

 

The car was originally map sensor on a fcon pro 2.1 with a atmosphere bov 

i couldn't find anyone in the u.s to tune it so I bought a power fc and afm's because it's a more accurate way to measure for my power goals . 400-500whp whatever it makes it makes 

problem is that right now I want to know if I should recirculate for engine/turbine health and longevity or if the power fc can adjust for when the bov dumps the boost?? 

my specs are 

ati balancer 

forged pistons 

Hks 3 row intercooler 

3" intercooler pipes and 

Aeromotive fuel reg 

stock inj 

stock cams as far as I know 

turbos mentioned above 

hks evc boost controller 

triple plate clutch

aem wide band needs to be put in 

not sure the model fuel pump but I know it's bigger too 

i have rc 750cc injectors with clips that I need to put in 

what kind of WHP would I be looking at? 

my filters and intake piping might be holding me up ? What do you recommend there ? I want to replace the rubber tube I have my chrome intake tube into if I can 

Also the tach and speedo are not functioning but fuel and engine temp and oil pressure are .. 

basically I want my car to be clean I have already done a lot im closing in I just need a little  more help 

to re cap  

Can a power fc with pro software be tuned to minimize harm from atmosphere bov? 

Wht kind of power is possible with my upgrades? 

How can I adjust stiffness of hyper max 3 coilovers ? 

what should I do about my intake/filter setup ? the rubber intake ripped so a shop just chopped it back and gave me that . 

How can I fix my tach and speedo ? Or good deal on another one . 

Car is on stock ecu and fuel pressure dialed back down and running running pig rich before I put my new power fc in since the old one broke. 

Also, anything I should know before going to a dyno as far as the motor goes? I have a fresh set of Ngk iridium plugs for right before 

I don't trust the shop it was at they screwed me so I have to comb back over everything before it goes to the tuner 

Thanks

Chris

More pictures bottom picture  is why I don't trust shops I took my bumper off at home when I pulled the car out of the shop for them slacking and not figuring it out and found it that way on both sides.. they expected it to run like that said it kept fouling plugs with a fried power fc plugged in and couldn't figure out why it was fouling plugs LOL Idiots. I had them pull the ecu and I sent it to apexi they said injector driver was blown. I bought a new power fc and pulled out of that shop. I'm trying to dial everything in for the dyno so I don't show up unprepared

Where to start.

I don't expect your car to be drive-able by the time you have done all your mods - it will need to be towed/trailered to the tuner.

It would have been easier to replace your F-Con with a Link - then you could have stayed with MAP sensor instead of AFMs

You need to work out what your power goal is first - you reckon your turbos can make 750hp in which case stock GTR AFMs and injectors won't do it. Ideally especially with AFMs your BOV(s) should be plumbed back but tuner may be able to work around that. Have you got a 3.5 or 4in exhaust all the way through? What are you using for wastegate(s)?

Intakes should do for now. Old coils can let you down so if they are original you need some new OEM, Splitfires, or something like LS2 Truck coils or AEM coils.

I have not worked on a GTR so other owners will have some more/better info for you.

I have rc 750 cc injectors I have to put in.  I plan on doing plugs swapping injectors in and going to the dyno I was using the stock ecu for troubleshooting and fault codes is there anything else I should do ? As far as the bov is it going to be an issue for longevity or just kinda like not a huge deal ? 

Not sure what wastegates I'm running I bought the car modified with the hks map sensor setup no one could properly tune it    Tho so I switched to the power fc

      New fix for low tyre pressure from bmw

      I believe Unimog is the only vehicle that has it (from the manufacturer). I haven't seen aftermarket permanently connected kits, but I haven't looked either.

      Ha ha ha, can't overthink when exhausted... Oh how I wish I had that power! I can be absolutely dead set shot, and my brain will still go "we need a good 3 or 4 hours to just think about everything and anything before you may sleep... My biggest thing is making sure I give myself enough sleep. I don't operate on even 7 hours of sleep! I attempt to give my body 9.5hours sleep a night to be able to function. I don't sleep the whole 9.5, but I need to make sure I offer a big window. I also take a single supplement, which is to help with long term health, and fighting inflammation, and I notice it helps massively. Especially me sleeping, and just less "achey" in the body. Have also kicked sugar, and gluten. A majority of people with ADHD don't go well with gluten. It causes a really interesting natural opioid overdose in the brain, which causes bodily issues and sensory issues.

      Yeah that's what I meant, permanently connected not manual

      Yep. But typically that's just run a hose down to the tyre while stationary.   Oh and the Unimog will automatically air up and air down tyres from the onboard computer for you too.

      There was a good video somewhere, maybe Kurzgesagt that linked physical activity to ADHD/Anxiety/Insomnia etc. Basically the body WILL spend energy doing something if you don't spend it doing anything physical. It isn't fun, but I personally have noticed I've never been overthinky, or unable to sleep if I'm physically exhausted from doing a lot. The musings around it seem to indicate that this is one of the reasons/mechanism that physical activity improves mental health/wellbeing etc, by more or less not using that 'extra' energy to overthink, be anxious, inflammation, etc. There's also the fact that every obnoxious exerciser ever says it's great and helps which is extremely annoying. Like people who say the same thing about travel being the best thing ever. I mean, they clearly are, but blah. I started doing a LITTLE myself (think 3x15min per week) and honestly did notice the benefits, aiming at life quality when older. Which is sooner than you think. Getting something into your routine that you can actually make a routine has helped me at least. This post brought to you by procrastination between sets.
