If you read the national inservice study on vehicle emissions, on the DOTARS website, you would see that most car on the road a gross polluters anyway. It seems that the majority of cars (80%) tested had engines that werent tuned, spark plugs that needed repacing, faulty cats etc.

Also, if a cat was so important, why dont bikes have them? why do racing cars run without them? why can rally registered cars be driven without them?

sorry, completely off thread topic /whoring:)

hey guys i know stuff all about being a mechanic, looks like some of u have really bad results while others have good results. Seems like most of u like to blame dynos, cats and such, but id say what it would come down to is to blame the tuner?? Id say there are some pretty bad tuners out there, id say some even work for big, well known workshops. Just my 2 cents. Ive seen mates get ripped by tuners! Where even i know what the car should b making and the money spent on it but makes f*ck all power.

Am i totally off track? Let me know what u think!

More HKS turbos . For those wanting an equally good turbo buy the Garrett GT28RS . Same turbine , nearly identical comp wheel (fractionally greater tip height) in TO4B cover . Unfortunatly its turbine housing is a .86AR (good) with the T28 flange (not so good) . It may be possible to order it without the turbine housing and buy the HKS .64AR T3 flange housing . HKS sells their housings separately , see Brett at GCG . ATP Turbo in the US also sell a turbo called GT2871R which surprisingly is nearly identical to the HKS GTRS , in fact it can be optioned with the same compressor . On the outside it looks the same as the GT28RS .

Both of these turbos are really crying out for that .86 Ar turbine housing so it may be worth trying to adapt between the T3 flange (manifold) and T28 flange (turbine housing) . I used the GT28RS on an FJ20 2 litre with great success , positive pressure at 2000rpm and a linear rise to full boost at about 3800rpm . STD actuator is I think about .8 Bar . Buy Garrett , no glits no surcharge same quality .

Cheers A .

I'm hoping for some good figures once i get a fuel cut defender or save a bit and get a power fc. I'm currently getting 215 rwkw at 12psi. Once i get the necessary upgrades i'll be boosting about 16 - 17 depending on how the stock injectors go. There's still much tuning potential to happen :D.

Oww and yeh, i have a highflowed T3/T4.

      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.
