Hi guys, my 26/30 will be finished getting built soon.

It's got a forged bottom end and will be in my r33gtst.

Stock r33 gtr turbo's will be on for the run-in and final tune due to finances, but am now saving for a decent set.

They will run 14psi and wont see the track

I have searched and came up with 2560's int gate.

My thinking for this is that i want more power than the stock ones can give me reliably and i only have the rears to get trackion.

So what do you guys recomend?

It's a street car first with occasional track use.

I'd also like to keep them a direct bolt on :(

Thanks Simon.

2530's/Garrett equivs would be my pick for a 26/30.

Blistering response due to the added capacity.

Be aware though, its going to take a very sensible & skilled driver to pilot it.

RWD and big power dont generally mix well with all people, ive seen it end in tears and hospitals many times over the years.

So its either those, or just get steel wheels in the stockers.

But IMO you want a little big of later delivery as with the 26/30 its going to feel like a V8 it'll have that much down low on stock/smaller turbos so it'll turn tyres in a blink of an eye.

But the offset is the larger ones will net you much larger power, but it will still turn tyres as it comes onto boost i reckon... so more of a danger trap!

And the above, is why i stuck with 2.6ltr/gt-ss personally :(

My RB26/30 is long overdue to be completed so should have it back soon. I'll be using the twin Garrett 2860 (-5 model). Hopefully I'll be able to give you some results. I am hoping it should make a great response car for street/track and make about 500 flywheel horsepower without too much stress.

Ye, the car in question was a 2.6ltr with those turbos (IIRC) and it was frying the tyres with absolute ease and great response.

So the smaller ones i have will be just that little bit more furious again, which im actually looking forward too coming from a GT30/270rwkw setup that came on around 4k vs this new one which will be a LOT earlier so it will be a challenge and a driving expirience im looking forward too having come from V8's years ago :)

Thanks for the replys.

I think i'll stick with the stockers for now. With some steel wheels.

Down the track i'll end up putting the engine into a gtr most likely a 32, and then slapping on some bigger turbos.

At the same time do some head work, and cams :nyaanyaa:

Should be some fun in a rwd though !!

Cheers Simon.

Yeah, melb sux in that way.

The engine will look stock and i'm going to try to keep it that way for as long as possible.

With the stock turbos on i'm aiming for around 240rwkw.

once the steel wheels are on ill push it more.

With only rwd huge kw's isnt going to get me far. Torque should be good :P

When the engine eventually goes into a gtr the bigger turbo's will be sourced.

I've got some R34 std turbo's for sale for $750. They'll be a nice upgrade from ur 33 turbo's, as the ones i've got are only 30k old and were on a stock car, also the R34's are ball bearing. I've also got a pair of new R34 N1's that came off a NUR that i was going to put on my 26/30, but im now thinking about some GT-RS's, ill let the N1's go for ~$3200.

P.S shamless plug i know, but just showing simon some options :P

Based on what, says stockers wont work good?

IMO, they would work brilliantly... keeping them to around 10psi as you dont need as much boost to make the power being that is less restriction with capacity.

It would be on boost very early and feel much like a V8 with delivery early. You cant say instant torque is a bad thing.

IMO - Very interesting to see how it does perform on the stockers i think, and im interested in the results of it.

I thought about GT-SS on a 26/30 for a while, just couldnt justify the cost of going 3ltr, or the hassle of fitment among other things.

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • 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.
