Hey mate.

Just curious as to why you say the High Flow's are only 300hp when GCG and a few other places all quote there turbos at 450hp?

Just did a bit of a serch and a lot of people are getting 230-250rwkw's out of there high flows... Sydney Kid being the exception with 264kw

Also Does it matter if I get a R32 turbo highflowed instead of a R33 one (if cost is a huge difference between the two)?

as I will be buying a 2nd hand turbo and getting that done so I can bolt it on when I have all of my parts ready to go.

I am looking to upgrade the turbo in the next month or so. Just waiting on the bank balance to rise just a touch more.

Thanks mate

Yes, the highflows are only rated at around that figure. And like I said previously, it doesn't mean you can't get 250 rwkw out of your engine with that turbo on. It just means that the turbo is working overtime and is not built to withstand punishment to that degree. Those turbos are capable of handling those horsepower figures but for how long? If you fit things like oil coolers and use a 360 degree thrust bearing, then you will have no trouble supporting 250 rwkw and still have a reliable turbo.

Another example.

Get yourself a 1000hp Skyline and bolt on a highflow turbo. Give it a couple of laps around Philip island and I bet there won't be much left of it. It will also reduce the performance of the engine somewhat.

It is all about getting the turbo that matches your engine and mods.

The other thing I forgot to mention was that I was getting almost 220 rwkw out of my RB20 highflow on standard injectors and standard ECU. That was pretty much the max for it though as injectors limit the horsepower.

So like I said before, you can still get the 250 rwkw but you can't gaurantee the life of the turbo. Plus for the extra $500 you would be mad not to put on something better suited and put out 300 rwkw

How much horsepower/kilowatts do you want? 230rwkw

What are you using the car for? eg. Street/drag

When do you want boost roughly? coming on from 2200...full @ 4000

Do you want power early or late in the rev range? mid-late - i dont mind a Little lag if if will give a better top end hit...must last to redline

What Mods you engine has or is going to have including computers or exhaust etc.? zorst, intake, FMIC, fuelpump, injectors, probably a power fc, possibly cams

Obviously, what car? S13 with a RB20DET

Intercooled? and is it large, small, medium? medium at his stage....VR4 cooler - apprantly flows enough for 230rwkw

Still running AFM or upgraded or no longer there? stock Rb20 80mm AFM

Custom exhaust manifold or standard? (custom exhaust manifolds give you more options) stock manifold - as below....preffered stock but non stock if price is right

External wastegate or internal(limited to virtually 450hp - internal gate preferred but external if price is right

thx jason :rofl:

Mate, if you only want 230 rwkw. I should be able to get you something for around $1700 that will come on full boost at 3000rpm and last way past redline.

General rule is....if your engine stops producing power, so will the turbo. Or even if the engine reduces in power, so will the turbo.

You would probably be best to go for something like a GT25/30. you would be best to wait until they come out with the T3 flange configuration as this will mean a couple of hundred less in fitting costs.

well i think i'll definately want 1x GT35r with the .82 housing so thats $1900 ??

and i may also want a 1.06 exhaust housing for the GT35r (my current one has .82) $ ??

if you want you can PM me more details or a contact number :D

Cheers

Dave

The 2530 on the RB20 is actually quite a nice combo.

Its all in by 4000rpm and makes really good power.

On the RB25 I think its a little small, especially when you consider they only make 220-230rwkw max. The stock turbo makes 190rwkw or with an adj. cam gear maybe 200 depending on the dyno.

Bare minimum on the rb25 I would go the 2535. 240rwkw is fairly decent for the outlay.

Comparing the rb20 to a 25 is like comparing a dyno graph of a 25 to a 30. :D

You are right, the 25/35 would be a better match with that engine.

I will be speaking to him tomorrow (Friday)

$1900 is correct for the Garrett GT35R.

He is getting back to me about the exhaust housing.

On another seperate matter. The T04's that I was talking about earlier for someone, he will be giving me an answer tomorrow also. He has been away in Perth for a few days so I haven't been able to contact him.

I have a contact who owns a very reputable TURBO business. They took over from Turbotorque around 3-4 months ago. I am getting VERY good prices for ALL turbos. I can pretty much get anything you want and to suit whatever. Prices are usually discounted by around $500 from retail so there are some massive savings to be had. Please post if anyone is interested.

EG. I just bought me 450hp Ball bearing turbo for a little over $1000. Retail on this particular one is over $2000 so you get the picture.

If there is enough of an interest I will see if he will give further discount for a group buy, however, a group buy is not essential. Sau members will receive further discount on top. These prices are NOT fitted. This will only put the turbo in your hand, or trailer - depending on how large you go.

where bouts u located.

    • 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).
