    I think the SS1PU is abit small for the Stagea as the engine is tolling a much heavier car. I think the billet SS2 or the roller bearing G3 would be a perfect turbocharger for this vehicle if it has to be a brand new turbocharger. Alternatively highflowing standard OP6 turbocharger is also a good option.

    Also ATR45 AKA ATR43G4 turbocharger on same car using same mods making 431rwkws @ 26psi. Not a responsive turbo, but super strong mid top end power and torque.This turbo should be able to pull some reasonable quarter times. Dyno sheet: Tuning video:

    Ok. as already been posted in the 400rwkws group, I've also trailed the ball bearing ATR45, or also called the ATR43 G4 profile for the Rb bolton series. This turbocharger is not responsive but ended up making 431rwkws @ 26psi. Pretty scary, foot down in 3rd and 4th, feels like the incoming air resistance is about to tear the whole car apart. It jumps from 120km/h to some where around 210km/h (stock cluster) in a blink of an eye. The RSR tyres held pretty wheel with a little wheel spin in 3rd and held all the way through 4th. mid top torque is crazy. I think this turbo can pull some series quarter mile times.

    The dump pipe plus cooler piping and all lines has to be changed once switched to a high mount manifold as every thing attached to the turbocharger will be sitting upside down. Probably want to get that turbo high flowed or get aftermarket power upgrade options if you are going that direction.

    Yes that is Abe. He's spent lots of time die-grinding all the ports of the stock manifold. Can't get his result with a stock manifold. 58T in theory should be making more because it has larger inducing area. How ever the car was out dated for a service using 8000km old engine oil. Recent runs were done straight after a service. Have to admit my car drove heaps better with fresh oil too. That part is arguable. My main concern is better transition and throttle response, and the current version satisfy that criteria.

    The turbine can flow plentiful, it is a larger trimmed turbine originally engineered to use with small housinged high flows. With the stock exhaust manifold, I can't get any thing pass 322rwkws on e85 (-40kws=98 power), and that is a SS2 turbo making 375rwkws on a proper high mount externally gated. So there isn't much more I can do apart from modifying the actual manifold or build turbos that shifts boost curve band n forward. To compare result with pump 98 internally gated simply: Power: High mount E85 result - 40Kws from E85 - 15Kws External gate So the new G3 would make: 376 - 40 - 15 = 321rwkws On pump 98 internally gated with a free flow exhaust manifold and exhaust setup. Using factory manifold it will cap maximum power output to the 280rwkws mark. But Factory log manifold produces better response, in comparison by 150rpms. So G3 can do 280rwkws @ 20psi by 3750RPMs. Probably a 76mm wheel with complete G3 housing assembly. If I can get the SL2 to produce 376rwkws without revving passing 7000rpms with 20psi by 3500rpms would be pretty sweet. Thanks for the feedbacks. Will be looking forward to see you results with some cams.

    Welcome to A Brand new all better and all mightier ATR43G3 turbocharger. The Older 58T version is now retired. This turbocharger have out performed the older profile of the G3 in both peek power and response. Both turbochargers had roller bearing cartridges installed. Thin Yellow and Red (18psi) is the latest G3 Thick Yellow is the older 58T G3 This turbocharger stopped making power at 376rwkws @ 23psi.

    I should have been here 2 weeks ago missing by 0.89kws. lol Here it is, with blessing of Queen Elizabeth plus emu and kangaroo screaming (jks, had 50c Coin welded to my wastegate port). My car stopped making power at 431rwkws. Using Hypergear ATR43 G4 roller bearing turbocharger. The red line was from the latest roller bearing ATR43G3 that was used for dyno scaling. please ignore it. Factory engine with forged pistons (9:1), stronger valve springs. Stock cams, factory inlet manifold. Run was based on E85 fuel, high mount manifold, 50mm gate. (No need for big cams to crack 400rwkws, just need a huge turbo).
  11. hypergear
    Well it made 30kws difference in power with less boost compare to the L2 turbine. Also peeks boost at the exact same RPM which is pretty interesting (Do have slightly lower RPM to Boost ratio before that point, result overlay at page 351) This turbo needs to be able to work internally gated, So reducing the trim on turbine end will probably hurt that. Small trimmed turbine might work ok on smaller SR and Rb20 engines, When you are bored of the SS1PU and ready for a high mount I can trim one for you to your recommendations.
  12. hypergear
    Yes it has stepped down to 56T. No point going for a 58T if majority don't have a setup and a engine for that extra power. This one was focused on throttle and transition response. It makes an great every day road turbocharger within the budget. This casting is in steel as usual.
  13. hypergear
    This is the latest G3 turbocharger. It has stepped down back to a 56T from 58. I've focused it on better throttle response and transition response. The prototype about is built in ball bearing. It felt pretty good on road comes on boost with very light throttle. hitting the dyno again on Wednesday and see how it goes.
  14. hypergear
    Stock VLT should be some thing like .46, Skyline is in .60. There is no way you can run 30psi out of that. to handle 30psi it should have anti surge slot as well. Let me know when you want to work on your VLT. I got some thing in mind that should make same power with lot less boost.
  15. hypergear
    the engine's not standard From the video description: the car uses a std exhaust & inlet manifold and a std throttle body Engine has rods, pistons and a hydraulic cam upgrade. If you count the time of when its stepped into gas the dyno ramp seems to be 16secs. Factory VLT Comp housing is smaller then skylines, You can see the comp housing in this video is larger. GT35 rear end should be able to flow that easily, and work well with long ramp. since its internally gated the comp wheel should be some thing around a large trimmed 76mm or a 82mm wheel in a .70 housing. Just my prediction of what the highflow profile might be. Never knows, I don't have personal experience with VLTs. Mod your VLT identical to the one in this video, send me your stock turbo and it doesn't take long to figure it out
  16. hypergear
    looks like a 3582 or equivalent in .63 turbine housing, which should be enough to flow that sort of power. That engine would've had extensive head and cam work, But I'm no Rb30 expert.
  17. hypergear
    This is the G3's turbo's power to boost behavior from 15psi to 23psi. From 23 to 26psi it didn't gain any more power, means its at a point the turbocharger it self or the stock cam shaft has maxed out. So in a free flow setup the point of when it stops making power should be around 23psi. Assume the tuning side is perfect Exhaust manifold do make a huge difference, the manifold VS graphs are in my thread. The cooler pipe assume in 2.25/2.5 inches, don't generally affect top end power, how ever longer piping gains lag while short pipes makes better response. Cooler wise a good 600x300x75mm cooler will do the job. I'm abit suspicious with the Inlet manifold setup, as I've had customer loosing 40kws after change over (probably have done some thing wrong), so might want to double check that. Also check the Cam gear and the cam angles, I believe Trev mentioned about the cam dialing issues that he had with the Type B Cams.
  18. hypergear
    You will find the BB G3 with the latest comp profile changes that power delivery behavior by a lot. It smooths the power delivery pattern, which takes out that big launch behavior, sticks the car on the road better.
  19. hypergear
    Well to get fast time you will need small rims with fat simeslick tyres (hint from Trent), I used to skit all over 3rd gear with a G3 on my road tyres and that was a slow 330rwkws. Run RSRs or better will help heaps. After doing abit of reading on the net, its not a bad time for a stock weighted R33 internally gated, stock manifold on pump 98 at that power level, there is a huge difference in mid to top end range torque with high mount and external gate after 120km/h. But I don't know how the car run slower and slower after each pull. Also G3 is changing, I will post some photos of the latest G3 tomorrow, in hopping for the same power level with much better throttle response, it will also be equipped with the latest bearing and lubrication setup as well as optional ball bearing.

    lol its Toshi. does the forum automatically correct spell mistakes? Not sure how it ended up in Toshiba (its been corrected)
  21. hypergear
    For budget, contact Toshi on this forum. He will be able to do a mail order remap for your mods at cheap price.
  22. hypergear
    yes same postal address
  23. hypergear
    You can run till it stops making power. Around 24psi Yes I can rebuild your bush bearing G3 into ball bearing and updated comp housing. in this case I will swap you with the one that is currently in my car free. I will need your turbocharger back for a day or two for a small modification on the turbine housing as well as the comp housing. The ball bearing update can apply to all Gx, Gx based Rb highflows, SS2, and SS3 turbochargers.
  24. hypergear
    I've been running the BB G3 with the latest comp profile for about 1000KMs so far and it appears to hold together well. I can swap this one with any G3 owner for free. PM me if interested. Dyno results of standard and latest BB unit: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-352 result only shown difference in 4th gear to floor. the transition and throttle response between the two is quite different.
  25. hypergear
    Will not win against external gate and proper manifold.
