juzz wondering is it worth it upgrading from an standard turbo r32 to a rb25det standard turbo ??

will i gain more power? bottom or top end?

will there be more lag?

when will boost kick in??

how much boost is it standard? and how much could i go max boost?

is it stronger than the rb20 standard turbo?

will it bolt up direct to my standard rb20 manifold?

do i have to change the oil and water lines? or will they bolt up too?

reasonable responses is appreciated as im in the process of doing this upgrade..

cheers!

Ryan

a rb25 turbo will make your r32 br20 go way better

i know of people with vg30 rolla bearing turbo on r32 and they go hard with the boost up but the boost starts late and goes all the way to 7500 rpm

you will need a fmic and bigger exhaust to make full potencial of this turbo im looking at a rb25 one or a vg30 one ...?

but the vg one has to have the oil lines made bigger or some thing so it will fit ...? you could probably use all your rb20 oil lines etc ...?

these will all bolt up to a standard 20 turbo

I am personally going for a hi-flow RB25 it'll set me back around $1950 for a hi-flow at GCG turbochargees in Sydney they told me that hi-flow is based in the middle of a stage 1 and stage 2 hi-flow. I've seen the difference in wheel sizes on the turbo and I can understand where the extra power is made.

A hi-flowed RB25 turbo will make roughly 20% more power on around 12psi.

So if your making around 170rwkw with 12psi on standard turbo you'd be looking at around 200rwkw with hi-flow.

thanks guys for your replies ..

but the rb25 turbo i got is not hi-flowed juz standard .. dont have the dosh to hi flow at the moment..

but will i be able to use the rb25 turbs without a fmic? juz standard IC?

my exhaust setup is 3.5inch to CAT then 4inch CAT back (CAT is 3.5inch)

is this exhaust setup ok? i was told its a GTR setup ..

i only feel lag on at the beginning then when boost kicks in about 3200 goes all the way to 7500 ...havent dont a dyno yet but this sat i might ..juzz to see wot power figures the rb20 turbo is giving then upgrade to rb25 turbs and dyno again ..

what are the power figures estimate on the rb20 93 mod wit 90thou klms with mods: hks pod filter, full hks exhaust setup (as above) with hks super dragger, std boost and std rb20 turbo ...????? i just wanna know so when i take it for a dyno i know what to expect ..

thanks fellaz

      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).
