The S1 does not have a steel comp wheel, I dont know a single turbo which would have a steel comp wheel.

However the correct statement is: They are essentially the same turbo, same specs and same ceramic POS turbine wheel. The S1 has a traditional alloy compressor wheel while the S2 has a nylon wheel.

I have no idea about the s1.5 yet the s1 and 2 will be interchangeable without noticeable difference.

Been ages since I've had both next to each other, but the compressor wheel design looked a bit different the way I remember it - the S1 had a twin blade thing going on whereas the S2 looked a lot more minimalist, the way I remember it. There could have even been a slight difference in size but it was a long time ago and I've pretty much lost interest in the OEM units :whistling:

      OEM Soko: Japanese business supplying Automotive items from Japan - Freebie inside!

      By Rezz · Posted

      We have some genuine Japanese legally decommissioned car number plates now in stock 🙂 Add some legitimately obtained JDM style to your Skyline or other Japanese model, or simply as a garage/man cave decoration! About the 40mm hole: The Ministry of Land, Infrastructure & Transport in Japan recognised the popularity of keeping decommissioned plates among car enthusiasts and came up with a method to "destroy" (or render them unusable for street use) while still retaining their collectable/usable value for display etc.  We have 40mm hole covers available to cover the hole nicely with a Sakura motif, which are also available in white in (very!) limited quantities, however they frequently sell out. Please let me know if you're wanting one or more of these and I'll check availability. The Sakura motif covers are more common. https://www.oemsoko.co.jp/products/genuine-decommissioned-japanese-vehicle-number-plate-set-su-7515 https://www.oemsoko.co.jp/products/genuine-decommissioned-japanese-vehicle-number-plate-set https://www.oemsoko.co.jp/products/genuine-japanese-vehicle-number-plate-400mm-hole-cover *Please note that we can't obtain particular number or area name (eg: "Gunma 500 Fu ・86") if requested. All plates are provided as they become available after decommissioning.

      RB20DET lean on cold start

      Ah, fair enough. For the IAT, I'm using a legit GM sensor that was used on the car prior to my current build. I'll get another wideband and IAT ordered and follow up when they show up. Thanks for the help.

      You shouldn't need to massively fatten up the mixtures for cold conditions. For one thing - 0°C is not that cold. For another, the Haltech will be using the IAT sensor to tell it how dense the air air, and calculate the correct amount of fuelling. Then the cold start enrichment is added as a % on top of that, so it should scale with the main fuelling. You might also doubt the IAT sensor at this time. You're not using one from an RB26 are you? Using a nice Bosch sensor or similar? Happens. Some wideband units take great pleasure in killing their sensors. Put another wideband in the tailpipe and compare. Or just swap the sensor to a brand new one and see.

      Oh, my misunderstand. When the car was running, it sounded ok, but if I gave it any gas it wanted to die but caught itself afterwards. It's very different from how it was a couple months ago when it was warmer outside. The logs show that the AFRs are better during, what I assume, is warmup enrichment. Because it's cold, and air is more dense, should I work on the enrichment bit?

      Rb20e and RB20DET parts

      By A31Skyline · Posted

      yess of course im not using 2nd hand parts from my spare engine, but the place where i live is hard to find parts for the RB20DET ,but for the RB20E is everywhere including new ones and a lot cheaper ,because for the RB20DET you have to order it overseas to get one and it cost a lot of money 3x the price to be exact. so i ask this topic because if i can use the new ones but for RB20E is it compatible or not. if not im screwed haha, not totally screwed but i have to save a lot of money first before i can begin repairing my engine, thanks for the information before.
