Street to Track

I have read through the "-5, vs -7, -9" thread, but they mostly compare the general specs of -7/-9 vs the -5.

In the end, all i got from it was that the -5's are laggy on stock displacement motor, and the -7's-9's are better for a street car on stock displacement.

Wasn't much info with the -9's vs the -7's though...-7's have a slightly smaller compressor wheel, not sure if the -7's are still capable of 300-350rwkw though, or what kind of power they are capable of vs the -9's.

EDIT: Re read - Seems to be

-7's = 300rwkw

-9's = 330rwkw

EDIT: Believe they are rated at the same horse power, maybe the -7's are a little less, but should be more responsive due to the slightly smaller compressor wheel. http://homepage.ntlworld.com/tbroom/Turbos.htm

Now even more confused, because on kudo's webpage, both -9's and -7's are rated at 620hp...

So who is right? :\

Quick answer would be good, ive tried searching through the forums and using google, but i take it my search skills are not quite up to par.

Havn't called GCG, I called up alot of the garret distributor's here in VIC, none had stock of the 9's. Apparently they are not as common as -7's...

Plus i made a bit of a mistake with Street to Track, I was informed today that the -9's were not available but the -7's were available for immediate shipment, so stupid me said to him to ship out the -7's impulsively after hearing that the -9's were not available. So now i think i will be getting some -7's in the mail...

Hopefully i can return them at get my $$$ back till the -9's come in stock.... I hope, otherwise i feel I am stuck with a inferior set of turbo's!

From the reading i have done, why get 7's when 9's are better?

So whats the big difference between them, while people recommend the -9's over the -7's. I don't think i have seen any facts/figures as to why they do.

Will either make 350?

I make 350 with -9s on 98, built engine though

I need to get my $$$ back. That is even assuming I can get them back...I mean I should be able too, I was thinking i could just send back the -7's and everything should be hunky dory.

Bit of a update, No refund avialable, but all good working it through with street to track, few miss communication's on my behalf.

I believe the correct turbo's i want are the Garrett GT2859R 780371 -1 or the GT2859R 707160 -9.

After reading through this mammoth thread http://www.skylinesa...lazy-gt2860-9s/

It looks like i need a decent set of actuators, are the ones included with the -1's alright?

I think i will be going a EBC as well, just to keep things stable. Looking at the Greddy Profspec 2.

Unless anybody knows of other Garrett turbo's that are superoir to the -9's? From the research i have done the -9's are better then the -7's in everyway (maybe not the exact same response, but 100rpm diff for more power seems like a good trade off)

EDIT: Re the recommended 1000 ID injectors, A buddy was telling me going to big of a injector can be a bad thing? It may give me a more rich tune, resulting in less power? Should i be going injectors that are smaller?

It doesn't look like there is much difference in price between smaller injectors of larger ones, It would make more sense to just purchase the bigger ones and be done with them.

EDIT: Re the fuel pump Bosch 044 intank install, Read the DIY, seems like a bit too much mucking around for me when you can get a pump that will go straight in? Walbro seems alright? http://www.kudosmotorsports.com/catalog/walbro-fuel-pump-kit-intank-walbro-gss341-255lph-nissan-180sx-rps13-silvia-ps13-skyline-r32-stagea-wgnc34-p-1079.html

The nismo is $594.....eeeeeeeeeeeeeeeeeeep! Man just can't catch a break $$$ wise with this car!

More of a update;

Tuner reckens stick with the -7's i have gotten...says there is SHIT all difference between the -9's and -7's in terms of overall power.

Says all the stock components are good for about 310rwkw, and running 20psi is bad for the stock internals, (well not bad but just shorterns the life quite a bit).

Reckens the biggest limiting factor would be having a poor quality cat.

    • Dredgggggeeee time; I have recently finally started driving the car. It sat for so long that the fuel tank gave birth to rust sludge and blocked my lift pump sock and one of my walbro 460's and left grime, rust chunks and muck all through the surge tank and system. I decided to commit and pull the trigger on an oem r32 gtr fuel tank and Frenchys twin 460 / sender / surge tank hanger combo and all new larger lines and fittings etc, also boost doc heater hose kit / new heater core and a heap of other bits and shits like wideband sensor installed in the dump and Syltech iacv + lines and all wired and added to current tune. now having lightly driven it a couple times without issue, I can happily report on the hta3076 in its current tune. still no boost control switched on, 20psi gate springs, car makes 22psi at 3200rpm in 6th gear with 30-50% TPS from cruise at 100kmh. Going by the old graph, this means it should be making 300-325whp at the same numbers above. Very very responsive setup under true road driving loads. all that's left for the build is body loom + PDM, finish the remote aircon setup, install carbon fibre parts and go for full tune and 30psi. the 315 rear tyres are now performing like they're 195's, wheel spin in any gear at almost any rpm, whereas my previous setup hooked up in 3rd no issue, albeit Nt01's back then / RB25 5spd vs (new) old date r888r's Z34 6spd now, + obviously all the support upgrades I listed in the quoted post above. car sits at 1-3psi on cruise at 100kmh, expectations totally exceeded and I'm beyond stoked with all this so far.

    • I've also been eyeing their rear axles for my car. I purchased seat mounts from them about 7 years ago and they were hot garbage so I've been a little wary about purchasing them. With that being said, please buy them and get back to us haha. 
    • Can a moderator please move this into the right category.. I've accidently put this into racing build thread 🤦🏽‍♂️
