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 :)

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
