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 

 

i will upload load more pics if you want let me know

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

      Fender flare widths across front/back of car

      By AdiR34 · Posted

      Hey y'all! I'm curious about how y'all go about widebodying your cars. I noticed that when running a square setup, my front wheels are a bit more tucked in than my rear wheels. Not by much, maybe 5-10mm. This leads me to wonder - when I widebody, should I use narrower front flares and wider rear flares? I found a set of 40mm rear flares that I really like, and was thinking of pairing them with some 18mm front flares, but I don't want the car to look strange. How have others done this? Note, I'm in a sedan. Thanks!

      And if it was anything other than an auto tranny part, it might be a problem. But seeing as all auto trannies belong in the recycling bin, it's fine.

      Stock rb25det neo questions

      By dbm7 · Posted

      All the schemas I can see, indicate your typical setup of ATF 'cooler' (read: heat exchanger) in the bottom radiator tank..ie; https://nissan.epc-data.com/stagea/wgnc34/5413-rb25det/engine/214/ ...but I can prattle on a bit here. These trannies have a thermistor in the sump ~ the TCU reads this and 1. bumps the line pressure up when the ATF is 'cold' and 2. prevents the TC lockup clutch from operating, until the ATF comes up to minimum operating temp (keeps the ATF 'churning' through the TC so it heats up quicker) -- trigger point is around 55C. In these conditions, the engine coolant temperature rises faster than the ATF temperature, and also helps heat the ATF up, which is why it's best to think of the in radiator tank setup as a heat exchanger ; the heat can flow in both directions... ...with these trannies, the 'hot' ATF comes out the front banjo bolt, flows through the cooler/heat exchanger, and returns to the box  via the rear banjo bolt. This gets a mention, due to the wildly different opinions wrt running auto trans fluid coolers ~ do you bypass the in radiator tank altogether, or put the cooler inline with the in radiator tank system...and then, do you put the additional cooler before of after the in radiator tank system?... ....fact is the nominal engine operating temp (roughly 75C), happens to be the ideal temperature for the ATF used in these trannies as well (no surprises there), so for the in radiator tank system to actually 'cool' the ATF, the ATF temp has to be hotter than that...lets say 100C -- you've got 25C of 'excess' heat, (slowly) pumping into the 75C coolant. This part of the equation changes drastically, when you've got 100C ATF flowing through an air cooled radiator ; you can move a lot more excess heat, faster ~ it is possible to cool the ATF 'too much' as it were...(climate matters a lot)... ...in an 'ideal' setup, what you're really trying to control here, is flash heating of the ATF, primarily produced by the TC interface. In a perfect world, wrt auto trans oil cooling, you want a dedicated trans cooler with builtin thermostatic valving - they exist. These should be run inline and before the in radiator tank system ~ when 'cold' the valving bypasses the fin stack, allowing the ATF to flow direct to the in radiator tank heat exchanger, so it works 'as intended' with helping heat the ATF up. When 'hot' (iirc it was 50C threshold), the valving shuts forcing the ATF through the cooler fin stack, and onto the in radiator tank heat exchanger...and you sort of think of it as a 'thermal conditioner' of sorts...ie; if you did cool your ATF down to 65C, the coolant will add a little heat, otherwise it works as intended... ...the 'hot' ATF coming from the front bango bolt, is instantiated from the TC when in use, so all/any flash heated oil, flows to the fluid-to-air cooler first, and because of the greater heat differential, you can get rid of this heat fast. Just how big (BTU/h) this cooler needs to be to effectively dissipate this TC flash heat, is the charm...too many variables to discuss here, but I just wanted to point out the nitty-gritty of automatic trans fluid coolers ~ they're a different beastie to what most ppl think of when considering an 'oil cooler'... /3.5cents
