hazjaz Posted April 8, 2013 Share Posted April 8, 2013 Hi all, I was looking for a thread with this kind of info but didn't have any luck finding one, please point me in the direction I need to go if there is one. Basically I have a BNR34 GTR with a couple of blown turbos, so now I am searching the market to find me a new pair (upgraded) and know there are a whole bunch of brand and types out there, so I was hoping to get some advice or kind of pointed in the right direction of manufactures and models. Currently I have minor mods such as a Haltech ECU, Fujistbo catback, Fuel pump and boost controller and have been dynoed at around 260awkw. I know that the Garrett -5 turbos are a popular upgrade to the 34's and have the potential to be reaching figures around 350+awkw which is what I would be after. With upgrading turbos I was looking to upgrade the cams as well, along with the front/dump pipes and other parts since I don't want to be in and out of the mechanics a hundred times. So if possible could people please recommend to me some turbos and why they would choose them. Appreciate any help. Cheers.

wolverine Posted April 8, 2013 Share Posted April 8, 2013 I typed in "RB26" "turbo" "upgrade" and that came up with heaps of threads plus if you try searching for "-5" you should find a lot of very relevant threads. Also worth looking at RB26 dyno results (stickied thread).

gtr jet Posted April 8, 2013 Share Posted April 8, 2013 -5's are known to be laggy too. You could get close to the power you want on -7's and E85 or just go -9's and win win.

wolverine Posted April 9, 2013 Share Posted April 9, 2013 -9's are less laggy than -5's. Stock dumps will be fine. 1 Link to comment https://www.sau.com.au/forums/topic/423175-r34-gtr-turbo-upgrade-needing-advice/#findComment-6810535 Share on other sites More sharing options...

GTR-34A Posted April 9, 2013 Share Posted April 9, 2013 How to -9 compare to the stock R34 turbos? At the moment my turbo kind of kicks in around 3500-4000rpm wont be hugely different lag wise in comparison to stock with a good tune, but will pull much harder, flow alot more, and make more power, especially on E85. stock turbos should kick in earlier than that (around 3k) with a good tune and cam gears though.. have you had yours tuned?

nomnomv8 Posted April 9, 2013 Share Posted April 9, 2013 (edited) Whats the duty cycle on your injectors atm?? You've already got ecu, fuel pump.. change to a decent flowing exhaust from front pipes back (id leave standard dumps and save your self unnecessary spending as back to back dyno graphs have proven the upgrade alternatives for your power goals make SFA difference and not worth the $$$), get some cam gears, some injectors if required, -5's and retune. edit: also budget for a new clutch as if your still running the OEM one it will go bang quiet quickly regardless of what turbo you choose Edited April 9, 2013 by nomnomv8 Link to comment https://www.sau.com.au/forums/topic/423175-r34-gtr-turbo-upgrade-needing-advice/#findComment-6810584 Share on other sites More sharing options...

Would -5 result in more lag then a -9? (I'm a little confused on the whole dash range). I got an excedy clutch, doesn't feal the best but its still quiet new Link to comment https://www.sau.com.au/forums/topic/423175-r34-gtr-turbo-upgrade-needing-advice/#findComment-6810913 Share on other sites More sharing options...
