get a ball bearing 2871r core into your rb20 or rb25 housings, for response use the rb20 housings, for more mid to top use the rb25 housing

also, use a good boost controller to bring it on early and keep it on as long as possible, if possible get some ethanol too and wind up the timing with a tune and 20psi of boost..

Ahh yep , well , tune , cam gears etc . It will never make full boost under 4k with that turbo (nor will most after market turbos)

currently making 15psi at 3.7k on a hyper SS1 still need cam gear adjust, advance cas timming and a tune

That's a hypergear , not gcg :P . I will change my statement , just for you my good friend :) , i have never seen a gcg high flowed turbo make full boost under 4k :) . That's pretty good old mate , even my old 2530 didn't make that by then!

I presume you are talking about an RB20 - if you look at my chart above you will see it makes full boost by 3500 rev/min on my old RB25

      I used the radium thing, makes the whole parallel assembly a lot more compact compared to any other way of doing it

      Racetronix also sells those ethanol content sensor bypass blocks. Adapter, Flex-Fuel E85 Sensor High-Flow Bypass, In-line No Sensor (ADF-FLEX-NS): Adapters - Flex Fuel | Racetronix Ethanol content sensor are originally designed to be on the feed line. These bypass blocks are meant to be ran in the feed line and not return. The continental ethanol content sensors have a 3/8" ID and not 5/16". This is why they are ran on the return line directly in conjunction with a low threshold sampling value VS in the feed with one of these blocks.    Haha we think alike, I used both original feed/return for 8AN feed, and one of the Hicas lines as a 6AN return. I also capped off and left the other Hicas line as a spare.

      R32 gtst speedo out by 10kph

      By -Jimmy- · Posted

      Interesting, I haven't read about the issue with oil getting into the speedo in the cluster before. I'll have to take more notice with mine. The speedo on my R32's when I've run factory diff and tyre size have never been accurate as far as I can remember. The non Type-M GTS-t did come with 15" 5 stud wheels and smaller brakes, but that's less than 5% of them.

      My R32 Money Pit & The Headaches That Come With It

      Good to hear the condenser you picked up off my brother worked all good. Do you think there could be an issue with your AC compressor itself or the clutch on it then? I don't know a lot about them so I can't really help but keen to hear what it ends up being. Keep the build thread going man, it's nice to look back on over time.

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.
