Took a few photos of things tonight. Here is a shot of the compressor off an RB25det turbo (s1). Note the definite steel wheel. I think most people know this by now, but here is a pic if you just want to see for yourself. I know I for one never got to see the inside of my rb25 turbo when I had mine as I never had a reason to. But when things are off its always fun to study them :)

Note the interesting twin blade compressor design..

that turbo wheel looks completely different to the one I have which i noticed when I went to replace my stock dump pipe. It looked plastic instead, definately not steel or as shiny. I have a pic of it at home. Is this because mines a series 2.

And a high flow Stock R33 turbo, You can tell its highflowed because of the thin wall on the intake compresser side and on the exhaust side its machiened right out to the edge of the exhaust housing.

Don't mind the bent fins on the intake side, they have scince been replaced with new ones. :P the bent fins were from thoes crazy japs running the car with out a pod filter.

Heres the exhaust side of the R34GTT turbo. Apparently that orange colouration is from runing octane booster.

Gordo:

The exhaust side on your turbo looks really clean. You can still see the white balancing marking on the fins. Have you cleaned it or has the turbo hardley been used ?

    • Not alot of room in the front or mid pipe to play with Helmholtz chambers, plus they are pretty hit and miss getting the length and volume right, and time is money when it comes to trial and error testing at a exhaust shop, it isn't like test fitting mufflers or resonators From previous experience with exhausts and trying to tone down the volume and eliminate some drone, a resonator in the mid pipe typically make it much better,  and even possibly stop Jackie complaining about it, me, I really don't notice it that much, but, I am pretty deaf 🤣
    • I know it's an entirely different engine, but I noticed practically 0 difference removing or adding 2x 3in (5inch body) 400cell cats (one in each bank) with regards to sound. So changing the cat to change drone I suspect will have very very, very, very, very, very very minimal impact.
    • 200 cell cat will probably help. Do you have room to tee off a Helmholtz resonator anywhere along the exhaust? These can do wonders for drones, with a little experimentation with regards to length.
    • The car revs up through the gears much better/faster now, and fuel consumption doesn't really seem to have be affected either on a Hwy cruise, which wasn't expected  The FAB9 intake manifold has been problematic sourcing though, I've contacted Plasmaman to ask about their intake, which you can get different runner lengths spec'd, and, their different options for throttle bodies  The only real physical drawback with the Plasmaman intake is how to connect it to my current OEM style airbox, as FAB9 make a OEM style back half of the airbox to suit the larger diameter throttle body, and all that is required is a 30°bend silicone pipe to mate the throttle body to the airbox Car also goes in for some exhaust work in a week or so to fit the biggest resonator they can fit clearance wise in the front pipe to help remove some of the drone, there isn't alot of realestate under there, a rough guesstimation is it will only be about 3-400mm long and maybe 90-100mm diameter, and with a 60mm exhaust that doesn't leave alot of space for the internal volume of the resonator to do its thing I'm thinking I may need to bin the "high flow" 100 cell cat for something a bit more substantial, yeah, and restrictive, like a 200-400 cell, to help, but, I have ample room for a really large bodied cat to replace the current one which has around a 4" diameter body I may look around in the recycling bins and see if I can find a massive newish cat that was "replaced" with some new full exhaust system that the local exhaust shop in Western Sydney is doing
