Are -10's the Garrett GT2871R Ball Bearing Turbos. You guys hav much info about the -10 in terms of when they come on boost, top end power etc? Do many gtrs hav this setup?

Cheers

Unless its on a 3L + I wouldnt go near them. I have RS's (pretty much -10's) on a 2.8 and they will be replaced with a set of -5's. Stupid choof choof turbo's

whats up with the last RB26 dyno post -5's @ 18psi and only 270rwkw ?? sure its pretty much a standard engine, but I had standard engine & standard turbos high flowed making exactly the same power at the same boost ??

theres quite a few others on there @18-19psi making around the 360rwkw mark ? doesn't look right

yeah stock turbos will make 270kw with some cam gear adjustment, 15psi and a good tune (my old car did and still does). still different cars get different results. no way to know what the tune is like, or the supporting mods etc or even how accurate the dyno is. at say 20psi I've seen -5s make between 300kw and 360kw. the mid point of around 330kw is about what they should make at that boost. anything more is gravy. :)

Wouldn't be surprised if they're -9's with a result like that

im glad i got -7's, they are so dam responsive, perfect for a quick street GTR...

my goal was to run around 280 - 300kw with the stock internals, but with sard fuel pump, nismo 600cc injectors, r34 gtr dumps/stainless front pipe/de-cat/3.5" cat back zorst, nistune, greddy cam gears, greddy profec b spec 2

so far only been road tuned on 18psi without cam gears dialed in, getting dyno tuned on the 12th of this month, hopinh for a solid number and a punchy mid range @ 20psi and gears dialed in

will post results in few weeks time :)

read through this whole thread and -9 > -7 from what i can see, also would a gtx3582r with .82 rear be compairable response to a pair of -5's? obviously be light switch power with the 35 but i was wondering if they would come on in a similar rpm.

I know time and time again people say just to buy garrets, HKS isn't worth the mark up.

BUT

would a GT-SS set up have ANY benefit, no matter how small, over a -9 set up ??

Also from my understanding, HKS kit comes with everything you need to install and the -9s are turbos only, would the cost be more comparable after you buy the rest of the necessary items to fit the -9s ?

thanks for any replies :)

    • That sounds like no chance of even importing one for road registering then Now I see why Duncan wants to check LHD rules for Targa...   I wonder how "bolt in" the AWD would be if you got one imported from the US and swapped it to an AUD one
    • Not to mention they drive like a bucket of bolts! yuck!
    • Ha ha ha, that's fair mate! We have the crackhead dogs now. Mainly because the missus wants the crazy dogs while she still has the energy and capacity to be able to keep up with them! Ha ha our current two are both Working GSD, there brothers and sisters (from the same litters) are in Police, Corrective Services, and I believe one did end up in defence force too. They're wild and fun, yet right now, both curled up asleep on the lounge room floor while we watch some TV. Mal is very likely the next dog (unless I get my couch potato guardian dog 😛 )   What are your Kitties names? Are you planning some house work, like those high kitty shelves, built in scratching post, and some cat passages from one room to another room?
    • Maine Coone, did look at but to big and fluffy As for performance dogs, we had Mals at work, performance dogs are fun to watch, but, way to much work for this old rooster
