The Power to boost behavior of the RB20det is similar to an SR20det on stock cams. like the G2 and SS15 versions works pretty well on RB20det in a T3x .64 rear that has been made to suit Rb20det's T3x print with 6 bolt dump.

There are very few Rb20dets around so its unlikely I will be invest into it at this stage.

2016 version of SS2 has many changes made to earlier models. The difference in end result would be a combination of alterations made. Ceramic ball bearing system makes difference in throttle response and becomes very apparent when working with low CPR, None VCT engines as well as cars with Auto transmission. It is definitely recommended for that Cosworth engine.

thanks for that Tao.

so the SS2 with CBB would be more responsive than the ATR43g3sat with cbb?

No its not. but current version did make more power externally gated. Im doing more developments into that at moment. But I dont think I can get any better.

Car is going on the rollers soon, just got my exhaust system modified again :)

Car still runs a cat, still smells great and makes less pollution than any VW out there (jokes). However you see what I did there? haha :ph34r:

It's 3.5" turbo back (all stainless), runs a 3.5" cat, 3.5" mid muffler, 3.5" resonator and a 3.5" rear muffler, however there's a stupid 3" restrictor or smaller right were the tip starts.. broscience tells me the EGTs are much lower there and the exhaust gases "should" be more dense.... let's see on the dyno.

Yes that's right no more screamer.. on the up side the exhaust is so quiet all I hear is spool and dose :wub:

Big shout out to Grub and his team @ Impossible Fabrications at Moorebank.. he built whatever I drew up/dreamt up and did it quickly and mind you cheap too!

Need to redo the wideband wiring, it's just there temporarily.. there isn't much room for it because of the le-hectic wastegate plumb back hahaha

Mr EPA won't like it, but Mr EPA can do the gas test and dB test and I'll pass (well pretty sure I will) lol

Is that the hks exhaust i sold you

You should of cut the restrictor out

Its a easy job and could have got them to reweld it

Just the welds around the exhaust tip you have to grind off and it slides out 1 piece with the restrictor

hahah yep.. I launched the mid muffler and the front section of the pipe work..

Tried that trick you said, the internal tube has been tacked into the meshing inside the muffler... chopped off the entire tip and all, wouldn't budge.

I'm going to get a slide hammer and go to town with it.. it no luck, I'm throwing that muffler.

With my old fujitsubo exhaust was like that and my kakimoto one is like that

But im just going to cut the restrictor with a small dremel and just remove it from the diff back and it should fall out as the piping is 3 1/2 inch and fairly straight

So i dont have to reweld it but ill leave it for now as it keeps it fairly quiet and shouldnt be much of a restriction at <200kw

Hks must be different

Logs to come, but the motor and turbo wanted to make more power but I stopped adding more timing and boost.

So yeah, stock unopened motor 1.75 bar boost, 1.5 bar by 4100rpm and an effortless 372kW :)

No more screamer, car even runs a cat. Stock intake plenum, stock modified exhaust manifold.

Many thanks to HyperGear for the upgrade and Mark at MRC for coming in on a Saturday to let me use his dyno!

Hahaha yeah man, drove it home after I tuned it. It's street registered :)

I actually stopped at 360kW then decided yolo, add more boost lol

The SR20 I tuned afterwards was horrible, full boost at 5.2k has rubbish BC cams that are useless. I'm going to help the owner take them out and bin them.

Sadly has decreased, my old SS2 dosed better :(

But, still doses nevertheless lol

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
