Hi all , the Pro S versions of the 2835 and 3037 usually work better than generic Garrett versions because they are model specific and tailored to suit the engines state of tune . Its all in the housings and dump .

Good results , I've often wondered how the 0.68 A/R 3037 Pro S shaped up on an R33 RB25DET .

HKS went to a fair bit of trouble with their GT Pro turbine housing and dump pipe for a reason - they work .

Does anyone with access to Nengun/Greenline know what they charge for this kit ATM ?

Are you intending to run the poncams to finish it off ?

Cheers A .

One interesting fact is that if using the OEM exhaust manifold, the HKS housing has to be relieved to match the larger than T3 flange on the manifold. So it bolts up, but still has the same slight mismatch facing the Garrett housing.

I'll have to grab a vid of the garrett equiv to the hks3037s; its quite a bit louder even with a stock air box.

Dale.. A friend recently did this with his gt35r 1.06 iw bolted on to the std exh. manifold and picked up ~20rwkw.

20kW is a LOT. That lip might only be 5mm or so, but it's got to cause problems with achieving smooth efficient flow into the turbine. The stock manifold does a good job, but the system doesn't need restriction like that when it's reasonably easily fixed.

The HKS unit runs a bell mouth insert within the compressor snout. Does anyone know if these are available for purchase? When looking into the inducer of the housing as supplied by Garrett, you can see the square edged lip that the insert sits into. That in itself would not work well for flow, and has to add to the HKS branded item. Just wondering.

I put a video response on that youtube vid of my Skyline (and a mates Supra - unfortunately I don't have video editing software to remove that bit :) ) blatting up the road in a similar kind of way, you can hear my Garrett 56T GT3076R with .82a/r rear housing doing the same thing. Definitely has a noticeable difference in spool sound etc. Exhaust note sounds a bit different though there are a few differences in setup between mine and Jasons - one of the majors being his being tuned on 17psi with 95 octane and mine being on ~1bar on 98 octane.

I agree, that lip would cause a bit of restriction, i didnt even think to check the internal measurements of the stock manifold flange compared to the exhaust housing, would have a gained a decent amount of flow/repsonse/power if i had the turbo matched to the manifold, anyway this might be fixed in the future, i already have a few plans in my head which involve a new custom made manifold :)

      Compressor flow comparison table

      By Lithium · Posted

      A lot of what you said there are fair observations and part of why I made that list, to make some of these things (like no advantage between the GSeries and GSeries II at PR2.4 in a lot of cases) however I'm not fully convinced by other comments.  One thing to bare in mind is that compressor flow maps are talking about MASS flow, in terms of the compressor side you shouldn't end up running more or less airflow vs another compressor map for the same advertised flow if all external environmental conditions are equivalent if the compressor efficiency is lower as that advertised mass flow takes that into consideration.   Once the intercooler becomes involved the in-plenum air temperature shouldn't be that different, either... the main thing that is likely to affect the end power is the final exhaust manifold pressure - which *WILL* go up when you run out of compressor efficiency when you run off the map earlier on the original G-Series versus G-Series II as you need to keep the gate shut to achieve similar airflow.    Also, how do you figure response based off surge line?  I've seen people claim that as an absolute fact before but am pretty sure I've seen compressors with worse surge lines actually "stand up" faster (and ironically be more likely to surge), I'm not super convinced - it's really a thing we won't easily be able to determine until people start using them.     There are some things on the maps that actually make me wonder if there is a chance that they may respond no worse... if not BETTER?!  which brings me to your next point... Why G2 have lower max rpm?  Really good question and I've been wondering about this too.  The maximum speed *AND* the compressor maps both look like what I'd normally expect if Garrett had extended the exducers out, but they claim the same inducer and exducer size for the whole range.   If you compare the speed lines between any G and G2 version the G2 speed lines support higher flow for the same compressor speed, kinda giving a pretty clear "better at pumping more air for the same speed" impression. Presumably the exducer includes any extended tip design instead of just the backplate, but nonetheless I'd love to see good pics/measurements of the G2 compressors as everything kinda points to something different about the exducer - specifically that it must be further out from the centerline, which means a lower rpm for the same max tip speed and often also results in higher pressure ratio efficiency, narrower maps, and often actually can result in better spool vs a smaller exducer for the same inducer size... no doubt partly due to the above phenomenon of needing less turbine speed to achieve the same airflow when using a smaller trim. Not sure if this is just camera angle or what, but this kinda looks interesting on the G35 990 compressor tips: Very interested to see what happens when people start testing these, and if we start getting more details about what's different.

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      By Joni Boi · Posted

      I know right. It baffled me. There's no way when the engine is off, key is in ignition, (coils are dissconnected aswell), also my sound system was dissconnected (I don't run any audio capacitors), battery reads 12.2v and with the 10amp fuse blown I was measuring 24 to 30v. The reading would move a bit from 30v to 24v which was weird. I took a pic of the multi meter reading 🤣: (This is a brand new single channel digital oscilloscope that also has a multi meter mode).   Before when the fuse was blown, I had one lead on the 12v supply (green/white wires) of that brown relay and the other lead on the negative battery terminal. When I turned the key on ignition (engine off), it would read 30v. Then when I removed that relay from it's plug and tried putting ignition on again, it would read 12v, but I think it's because it can't turn on the ecu now that I removed it. I asked Chatgpt and this is what it had to say:   Not sure if those theories would be possible but, any auto sparkies here? welcome to confirm. 🤷‍♂️  No idea, but if it happens again, atleast I know what type of issue it is, unlike last few months where I didn't know what was causing all my issues and I was just taking stabs in the dark to figure out what type of problem it was. If it does happen again I'm going to investigate futher and trace back the source even more and inspect more circuits. I drove it to work this morning and the car drove and boosted fine. Yeah I was thinking the same, so I've imported my back up saved map (which is the map that I saved when it got done tuning) back onto my haltech with the base fuel pressure set to 43.5psi.

      Yeh nice, if your in melbourne could you recommend any exhaust shops in the east that do a good job?
