I'm not after a turbo ATM but found this pic on my PC which might help some of you guys trying to figure out what you want. Obviously there are many factors other than a power target that will dictate what you want but hopefully this will help anyway :P

Daniel,

What can your guy do for my stock GTR R32 turbos? I'm only looking for a bit more out of them (maybe 210-230kw atw) with reliability. What cost for rebuild with steel wheels, and what cost for hiflow etc? What do you recommend?

I am getting a price for you on a special turbo available now as a direct bolt on replacement for the GTR's. I asked him today and he will hopefully reply to me tomorrow. Like I said...direct bolt on, so everything just goes back where it came off. They are both twin ball bearing and rated at 300hp each. Highflows are gonna cost you $1400-$1800 depending on condition of turbos and how tough you want them. I dare say these other BB turbos will be around the $1700 mark but I will confirm tomorrow when he calls me.

do you have the garrett gt2871r in stock or turbo equivalent to this??

I asked him today about this and he is looking for me tomorrow. He thought that turbo was the same as the GT28R which is $1400. I asked him to do some more research on this one to find out what the go is. I will let you know when I do.

I believe there 2 different turbos.

Very interested if you can get them.

Thanks

NFI:confused:

Totally different turbos. The gt30 does not come in an internal gate. That combo was a GCG combo using the standard skyline exhaust housing . This combo has been proven to be very unreliable. The only other way to do it is to buy the HKS ex housing which is very pricey. The GT35/40 rated at 700hp is internal gate but only come in a 1.06 ex housing A/R at that rating. HP in a box do a 0.63 but it is not rated at 700, I think it is closer to 500-550hp.

I have done a highflow for Syphon and a GT35R for Skyrine-Dave.

I officially have no hair left!

I also want to know is the GT30 with internal gate 0.63 comparable to say a HKS2830...or do I have NFI...
No F@#%in Idea

I was looking at the horsepowerinabox one with the internal gate

I am REALLY after a direct bolt on similar to the HKS2835 I think...or maybe the HKS2830 (I may have these wrong as I have NFI...)

Sorry, I just read my last post and realized how rude I must have sounded. I didn't mean you had NFI and appologise for coming across like that. Ummm...what car is this going onto Bob. The reason I ask is because the HKS 2835 comes in T3 or T2 flange but the garrett equivalent only comes in T2.

You would probably want something like the aforementioned GT3071. It is internal gate and rated at 400-450hp, T3 flange. I am currently trying to find out how much it would cost to highflow this turbo by Garrett as this would place it well into the 500hp mark and make it a good int gate bolt on comparable to the GT30R.

Dan, you weren't rude bro...I HAVE NFI...there is no much contradicting info re turbo's that I am just over it...I know what I want.

I want a turbo that will have good response for street and occassional strip, probably a 0.63 rear housing, internal gate, bolt on no changes to any lines as they are all new...

Car is a R33GTST, rebuilt...only want to run a MAX of 14psi when i get an PFC and front mount and larger fuel pump.

So that means T3 flange, I have seen good results from the HKS 2830 from some people, but the efficiency curve according to my calcs in better suited to an RB20, where as the 2835 is better suited to the 25...

What is 400-450 in kw...I don't want a monster that comes on boost hard I want something reasonably responsive which aint gonna happen with a 1.06 rear housing...

That 35/40 with the 1.06 housing was actually designed and flowed to be on a 2 litre 6 cylinder engine. They reckon it should come on boost at 3200-3500 depending on whether you have the 2 or 2.5 L. I don't know how true this is and I don't want anyone to be a guinea pig for it. I would rather just ask someone who has already got one on.

As for direct bolt on, you have three options...these are:

1: Highflow

2: HKS

3: Buy a different car

HKS and Greddy and companies like that are the only ones that have made the direct bolt on stuff for Skylines in the smaller stuff with internal gate unfortunately....you might be better off waiting until they bring out their T3 range. Even then though...anything Ball bearing will have different fittings for the water and oil lines so that rules all of them out.

    • 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 
    • 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.
