hi all, I have a couple of questins regarding a hi flow turbo that i am considering buying (i have a lot to learn when it comes to turbo's), I only have a certain amount of information at this point about the turbo but the rest of the info will be made avalible to me as soon as i know what questions to ask.

here's some info on the turbo:car was taken to geebung drift king with blown turbo. they removed it and sent it off to Garrett to get it rebuilt. apparantly its a pretty custom jobby. 300zx turbo housing high flowed with steel wheel, rb25 compressor housing high flowed with steel wheel. (there are recipts for the work done on turbo)

would a a 300zx rear on it make it spool quicker ?

at this stage i am assuming it was origionally a R32 stock turbo at the begining, will this be a straight bolt up to my Rb25det?

will it be a better than my stock R33 turbo?

my stock turbo comes on nicely a 2000rpm and currently running 12-13psi daily

reason for buying this other turbo is so i can happily run it at 1bar daily,if and when i deciede to get it out on the track i will be happy to wind it up to 18psi and have my stock turbo laying around as a spare, i would appreciate any constructive input and answers if you have them, if you have any questions u think i should put forward to the owner please let me know, cheers Damo

shirt answer is YES. it will bolt on and be an upgrade.

Long answer would invole you answering more questions which you won't know the answers to as you are not the workshop who took it apart and measured bits.

that depends matey. The is it the 300zx twin turbo? or single turbo. The twin turbo one is no good.

Only the single turbo one - also known as the vg30det turbo - not the dett

I hope/believe it is the single turbo. why is the twin one turbo no good?? thanx in advance Damo

the twin turbo ones use a t25 flange (and are too small for your car), the single uses a t3 flange - same as your stocky.

If it has OP6 on the exhaust side and the usual R33 compressor housing it might just be an R34 turbo thats been rebuilt.. If hat has been hi flowed and rebuilt with steel wheels ur laughing. I recently bought a 34 turbo (stock) and it has the same VG30 rear housing from a Z31 3L single turbo V6 and same compressor housing as the R33. Basically the upgrade to an R33 RB25 turbo is it shoudln't run out of puf at the top. If urs is a hi flow u should see some good gains, bit more lag, more top end. Thats what it sounds like to me. A good indication of a hi flow turbo is the rear housing, If there rear wheel is large enough to come close to outlet maximum measurement its deffinately been enlarged.

      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.
