comes down to HKS 2530 and the Garrett 2860-5

while u pro's are still around, are the 2 HKS and Garrett "bolt-on" turbos without modification?

and where in Australia can i buy the Garretts from?

Snowman mentioned http://www.gcg.com.au , but they're offline so im not sure how much they are etc....

and thank y'all for the feedback/replies, very useful information (for me and im sure for others too)

they are both bolt on, but the HKS ones come with all the gaskets and new bolts etc. the garretts are just the turbos. and I have heard you will probably need to rotate the comp cover so it's on the right angle. the HKS ones come already set at the right angle.

I've run my GT-RS on both a standard capacity and now with a 2.8L crank.

As many have said (although not all), the set up on a 2.6L was really too laggy for my liking.

On a 2.8L, well that's a different matter altogether!

My vote is 25/30s for a 2.6L.

They are more than just re-badged.

There is slight differences in whe wheels used. Not a lot, but enough that they certainly are not rebadged.

Whilst Garrett makes the HKS turbos, thats where the similarity between HKS & Garrett turbos ends.

A little while ago this topic was discussed in great detail.....

All of the turbo's Made by Garrett came identical or a whisker short in the specs compared to the HKS ones.

The good thing is that HKS give you all the other goodies to go with the install...gaskets..washers...bolts...copper washers etc etc etc.......

HKS also have a special actuator...heavy duty that they have made especially for themselfs....but this is just to make a difference in the two product.

I believe the AWKW's compared to rwkw's is a strongly debated item in this Forum.

But I was told by many in over these last few years that awkw's x 1.2=rwkw's.

Cheers

so the 2530 is a re-badged 2860-5?

same make?

Fitted RB25 AFM's

Tomei Poncams

@ 4 Wheels

Max Power 274.7kw @ 6963 RPM (1.3 BAR)

Max Torque 924.8 Nm @ 4803 RPM

Max M.A.P. 230.4 kPa @ 4665 RPM

what is that equivalent to rwkw?

It is not just about how many.....what figures.....car doesn't have enough horses...etc..etc...it is not a dyno race..though some people think it is.

The car needs to feel right,handle well and not loose traction.....

I have a 0 to 100km an hour figure at 4.5seconds and the quarter mile at 11.8.

The car is driven everyday and I have chosen a safe tune with less boost(1.25 Bar) to make it last alittle longer.

Oh Beer Baron...sorry did not read your post...double posted all the goodies you get with the HKS kit.

Cheers...good luck with your venture

hey there, i have just got garrett 2860-5 installed, r33gtr, as i replied in a forum a few days ago, the tomei dumppipes didnt fit up to turbos, custom piping, inlet to turbos (to fit air cleaner) and some intercooler piping all custom made. oil returns, water returns to turbos all modified, big money :laughing-smiley-014: will post some photos when car comes back........

Should have bought the correct turbos, the real -5 are direct replacement...done many times.

-5's and 2530's are different enough to make the 2530's perform far better infact on average the GT-SS perform better than the -5's.

-7's aren't the same as GT-SS either.

I had a quick look over some of the results (about 10 to 12 of each type except for the GT-SS , they seem to only just start to be flavour of the month) and did some totals of cars that are similar, standard capacity rb26's on pump fuel. I didn't include some of the hardcore 2530 setups like dirtgarage's to make it a little easy on the -5's.

The average for the 2530's is; 388rwkw

The average for the GT-SS is; 335.4 rwkw

The average power made by the -5's is; 313rwkw

Of the same data the best power of the -5's was 388rwkw

Best of the 2530's was ; 451rwkw (have an examples of a few a fair whack higher again but, left those out).

Best of the GT-SS was 364rwkw

going purely of budget un-opened/ non-built motors maybe with just some drop in cams it looks like this;

-5's average ; 298rwkw

2530's average ; 358rwkw

GT-SS average ; 332rwkw

-5's aren't bad but, then again they aren't HKS either.

HKS do enough to make the turbos work better than garrett's off the shelf. In some the case of the -5's it's a few mm or fractions on the inducer /exeducer and trim, basically a different wheel made just for them. They also have their own housings at least on the compressor side and sometimes as we know the exhaust housing too.

I thought the GTSS is similiar to the N1s?

Anyway, i've got 2860-5 and 2860-7s for sale :)

i need a bolt on, and injectors and rail, for my 33 up to that stage now,

what way shuld i go and costing if some one knows????

have wolf v4 and all other bolt on u need, need fuel pump az well

thanks for any help

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
