Most responsive turbochargers - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Alecci · 17th July 2008, 10:50 AM

As it seems I may soon be in the market for a new pair of turbochargers I'd like to find out which ones are the most responsive (quickest spool-up) if I wanted to attain 600 PS at the flywheel with a standard displacement RB26DETT.

There are lots of turbochargers out there, and while I have seen the diagramme of the different turbochargers' powerband as well as comparisons between two particular types of turbochargers (i.e. HKS GT2530 versus Garrett GT2560R -7) I've never seen a comparison between all/most turbochargers considering what I specified above.

Some turbochargers that come to mind:

HKS GT2510
HKS GT2530
Trust TD05H
Trust TD05SH
Trust T517Z
Tomei ARMS B9046
Tomei NEO
Nismo N1
Nismo R1

Etc.

Please share your thoughts!

HKS GT2530

Alecci · 17th July 2008, 12:14 PM

I was under the impression that the HKS GT2510 could handle just about 600 PS at the flywheel but being more responsive than the HKS GT2530?

There is no such thing as turbo lag. There is no such thing as spool up time.

There is a boost threshold, which depends on the amount of air flowing through the turbine housing. This is dependent on engine speed, size and Volumetric Efficiency of the engine.

The lowest boost threshold will be found in a very small turbo, like a single K03 off of a Volkswagen 1.8T. It will also puke and die, be outflowed by about 3500rpm.

Perhaps you should reword your question. maybe, What turbo provides the lowest boost threshold and will flow enough to make xxx wheel horsepower? Or, what turbo provides a low boost threshold and will not puke and die up top?

Learn how turbos work and the proper terminology, and then you will be able to come to an educated decision re: what turbos to put on your car. Or you can be like the hundreds of other people that have figured it out before you and put a pair of GT2530's/GT2860-5 or -7' on.

Alecci · 17th July 2008, 09:08 PM

Well, my sincere apologies for not being versed enough in neither the English language, the proper terminology nor the technical know-how.

I thought I had posted a straigh-forward question that would be able to help me select a new pair of turbos, should the time come when I had to make that decision.

You've proven me wrong, thanks.

Please close this thread.

UKPAISLEY · 17th July 2008, 09:14 PM

For 600 you will be getting full boost at about 4000 RPM,

dazman · 17th July 2008, 09:52 PM

Hks 2530s mate,ive had some fitted a few months ago,pulling 570bhp atf and trust me,fooook its responsive !!!!!!!!!!!!

Spearmint · 17th July 2008, 09:54 PM

A harsh response from the Samurai man there....

Personally I'm looking forward to someone using a twin set-up with the billet turbo's you get from AUS.

I would love to see some dyno charts between 2 of them and 2x whatever the Samurai bloke banged on about.

Chill mate.. Alecci was only asking a question

hyrev · 17th July 2008, 11:32 PM

GT-SS, although it may be right at the threshold of genertating 600 @ the fly.
I sure hope I worded my response correctly, would hate to get flamed.

GT-R Glenn · 18th July 2008, 12:30 AM

Well to be honest, there is so much info already on this website that address's and answers the question , I dont even understand why you would ask it .....
Im not trying to start an argument, but at least half the post's here appear to be by people who dont want to help themselves.

Just looking at the current post's on this "Turbo" page , theres at least 4 threads that discuss and answer it already.

You probably want GTss or garrett equivalent.
2530's wont respond as quick but will make more power, so here we go again discussing the exact same thing again.

Also, I love your signature.

It's like walking into the library and requesting and expecting an answer from the librarian.
She's most likely going to say, "I dont know have you read the million or so books we have available?"

Alecci · 18th July 2008, 08:29 AM

Like I pointed out in my starting post, I've seen some threads comparing two types of turbochargers with each other, for example, the most popular to compare at this particular time seems to be the GT2530's and the GT2860-7's, or the GT-SS's and the GT2860-5's. Perhaps I've also seen a thread comparing the Nismo R1's to the Trust T517Z's.

Fine, but it's just that. The threads in here more often than not only compare two types of turbochargers. Reading a thread on 2530-vs-2860 and another on R1-vs-T517 doesn't tell me which one is the best between the 'winner' of those two threads.

Therefore I wanted a thread were I could compare all/most suitable turbochargers known to be used on the RB26DETT on a somewhat regular basis.

I've seen a lot of threads comparing two brands of pistons, but when someone posted a thread listing most popular pistons and included a poll, I didn't see that person get flamed.

Fair enough, I couldn't care less for people having such an amount of spare time that they reply to threads without addressing the topic at all or doing so in such ignoble and mockingly expressed sentiments that the reply doesn't do the author any credit.

dazman · 18th July 2008, 08:53 AM

Ive seen this happen a few times on this forum mate,dont let it get to you,take no notice. Like i said earlier i can only go by my experience and the 2530s are great. My mate had gtss and ran them at the max for 4yrs,they went pop last week. Something to bare in mind if your looking for round the 600bhp figure,id rather have turbos with a bit to spare than at the limit all the time.Oh and i know a lot depends on the set up of the car but mine seems more responsive than his was ;-) hope ive helped mate :-)
