hey guys got 2 seperate problems and in need a bit of help

car is a 32 4door 20det,major things; hks cams, blitz turbo, rising rate fuel pressure reg, standard bov, fmic, exhaust, boost tee, standard ecu, aftermarket fuel pump (not sure on brand)

PROBLEM 1:

Im under the throttle little bit hard. Put clutch in and let revs drop, it basically just stalls.. or drops down to like 300revs then will all of a sudden pick up? But some times randomly like today in stop start traffic it would sometimes stall, even in neutral, highway driving etc. is fine its just when coming to a basic complete stop!!

PROBLEM 2:

boost will stay around 0.5 bar, sorta hard to explain but was looking at the turbo and line that goes from actuator to boost tee then boost tee back to a nipple thats on the turbo?? thats not right is it?? so i unplugged the line that goes from the tee to actuator so it would free boost, went around the block, turbo is alot noisier now (spooling harder etc.) seems to pull a bit harder but still stayed around that 0.5 bar mark

ive tryed my best to explain to it!!

PLEASE HELP!!!

Problem 1 sounds like an AAC issue.

Problem 2 - don't EVER disconnect the hose from the wastegate actuator. I don't care what the gauge says, you will be building enormous boost levels because the wastegate will not open. It sounds like the hosing is correct - I'm guessing the tee is to a bleed-off valve.

Well thats problem #1 covered off, stock ECU with FPR and bigger turbo, your crazy.

really?? that is a load of crap heaps of people run stock ecu with same mods as me lol

besides it WASNT the ecu as problems are all fixed now, (dodgy bleed valve, fuel psi was wound up to high, f*cked plugs, manifold gasket leak

      3D printing fun

      By Sean'O · Posted

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.

      When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
