are the oil pump gears a replacement for the standard pump ?

how actually makes them ?

yep they are a replacement for the standard pump

they wont fit the early model R32 RB26 crank shafts, this is the reason why im using a R33 RB26 crank shaft

how actually makes them ?<----- u mean who actually makes them?? its a CNC machine shop in sydney but its heated treated by another mob also in sydney

Fcuk man, surely everyone is getting sick of the twins V's single debate.

Anywhoo, im really interested in the oil pump you have. Any chance of PMing me with some contact details and a price?

Thanks mate,

Shaun

PS; Single all the way.

I thought I'd read through this whole thread , backwards as it turns out , to see the original spec sheet .

I'm reasonably sure that the "T3" flanged twin entry turbine housing is a modified GT32 casting which you can see at the turbobygarrett site under GT32 .

Geoff Raicer (FR) has mucked around with a few TS housings on GT3582R's and that one sort of works (sort of) ok on the 35R but he thinks and I agree that it's a bit small for the compressors capacity . Don't quote me but I think I remember reading that he thought that GT32 0.78 A/R TS turbine housing became a bit flow challenged at figures approaching ~ 500 Hp .

Now it depends on your vews of the TS system but he thinks that when changing from single to twin entry turbine housings the best idea is to go up on A/R size to benefit from lower turbine inlet pressure for about the same or better turbine response .

The modified GT32 housing has been used on GT3071R's and GT3076R's with some success and this may be because the exhause flow capacity is more in step with those compressor wheels airflow capacity , 440-540+ Hp .

I've often wonderd how a set up like yours would go with a GT3076R substituted for the GT3582R but you don't tend to see 3076R's as singles on RB26's .

Back to the TS GT3582R , in the US some have fitted modified "T3" flanged TS T04 turbine housings though some think the ports through the "T3" sized flanges are not big enough for the sort of exhaust flow a 3582R can generate on a well set up engine .

Garrett were supposedly going to do a TS T3 flanged turbine housing in I think 1.06 A/R for these turbos this year but nothing on the shelves yet that I know of .

Best of luck with it , cheers A .

TS T3 GT3582 would definately choke. Thats why Geoff is currently developing T4 TS for the 3582 and 4088 turbos. Even the modified GT32 in TS .78 is marginal for a 3076 thats probably why they really make no more power than the 3071 in this format. If going to a 3076 TS I would use the .82 A/R TS housing.

The whole twin scroll thing is really about broadening your power band. It does this by pulling the torque and therefore power curve to the right because of the improved VE from reduced back pressure. You can then step up the ex A/R and this gives you back the top end as well.

I'm not up with what he's doing ATM but he did try the hard to get the "Tractor" TS turbine housing but it's a screwy T4 flanged casting with T3 sized inlets in it . I think it's ratio was 1.06 A/R but its based on a dinosaur T3 turbine (no kidding VL T3 type) so lots has to be machined out to get a 68mm GT35 turbine into it . I think he did test one but the ports were really too small for a 35R .

The one he used to like a while back was a Turbonetic thing called F1-35R . From the pics it looked like a large frame Garrett ? center section with no water cooling and whatever Turbonetic calls an F1 35 turbine .

I'm not sure if the ball bearing pack is Garrett or some Turbonetic ceramic (caged) bearing system .

Garrett is really letting us down by not developing TS turbine housings for the petrol spec BB GT30 and 35 based turbos .

Twin integral gates ones like IHI and Mitsubishi do would make life really easy for us but they must not think there is much of a market for them .

Cheers A .

The new T4 setups Geoff is currently developing have T4 TS inlets not T3 - i've seen the pics of the bare manifold and with the turbo's on the manifold.

In the case of the SR's this new range of manifolds also have dual gates for true twin scroll much like the rest of the Full-Race range (previously only single gate gate for the SR's). Looks like there will be a range of T4 based Borg Warner turbo's as well. Check out the Full-Race website.

im not looking at making 500hp which is why i went with this exhaust housing

i dont intend on doing any bottom end internal work apart from the oil pump and new bearings just to freshen up the bottom end just so its abit more of a reliable daily

im running a GT3076R with the same .78 divided exhaust housing on my 180SX SR20 but its got a P12 SR20V cylinder head conversion getting done as we speak

the exhaust manifold is also a twin scroll manifold but it doesnt run twin external gates it has outlet's coming from both side's of the collector merging together at the gate

CIMG0289.jpg

runners 1 and 4 are divided from 2 and 3

manifold is design with very close to even runner lengths while trying to keep the runners as short as we could

havent got results on this setup yet because its taking alot more time to finish then i once thought due to the amount of work going into the engine and fuel system but once ive got some results ill be posting them up

Where abouts on the website is the details? Just had a bit of a look and didnt see anything

Funny thing i did see was - you can run 700rwhp through a stock bottom end with a "conservative" tune... i think they be tripping personally :whistling:

      Unpeeling the Orange

      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.

      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).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
