That will cost you $800 to high flow to 450HP.

hey guys im currently running a r33 series II with Blitz Cooler LM,turboack exhaust,turbotech boost tee,apexi pod filter.. would i be able to boost up the turbo more higher?like say 14psi or so. or would i need to tune it with a computer..

Yes it will still cost $800 to high flow as its basically using factory housings on a new Turbo core. So you might want to send in a cheap blown one to do the high flow. The ATR turbochargers has no issues to handle 25psi. But factory turbine housing can only hold 20psi.

Bit of a n00b question here...

I have been running a RB25 turbo on my RB20 at just under 1 bar for a while now. So that would be approximately 14psi (I know people are going to say I am not meant to, but I have not had problems so far and there are mixed opinions on this)

Would highflowing it, which would only give me another....say 6psi of boost....really provide THAT much of a power increase? Since the housing is kept the same, and the internals are upgraded, wouldn't this mean the volume of air which can be moved would stay the same? Or is there more to a highflow than I thought...

Once again, excuse the n00bness of the question.....

It will involve honing out the compressor and exhaust housing's to accommodate for larger wheels. Larger wheels means more volume of air is pumped. More air means more power.

Ok, so they are larger wheels, not just stronger ones which can handle more punishment...

The ATR28 450HP profile we made 255rwkws on a CA18det, RB25 should be making towards 270rwkw with excellent turbo response.

these seem to be quite similar to my setup which I have had for a few years. Tuned with all the right mods and its consistantly making 270rw kw and has done so on a number of dynos hub corrected and roller so i'm confident its about this figure. I paid like 1k back then, pushes a good 1.2/3 bar and has done for some time now. I really like the response and I'm sure this would be similar.

Ok, so they are larger wheels, not just stronger ones which can handle more punishment...

First of all we have to use bigger wheels to flow more air. We use aluminium compressor wheels and Inconel steel turbine wheels. All parts in the turbo are specially designed for high boost, and we warranty that for performance applications. So yes they are lot stronger then the stock turbo.

do you guys have a turbo that is say comparable to the HKS GTRS?

looking for the most response possible, and maybe 230-250rwkw

also highly interested in a bolt on solution to twin rb26 turbos, as well as dyno or pics and specs

    • 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.
    • 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
