I could be wrong, but I'm pretty sure it's the other way round mate.

Who's telling you this? The seller?

-9s are An updated version of the -7s, pretty much the same response as the -7s but flow a fair amount more. -9s on the same set up make more than the -7s etc...

i spoke with DVS Jez, and a few other ppl they will make the same power diff is, the -7s have more top end and the -9s have a bit more down low, but in the end they will both do the same job.

also ill be getting a platnum pro plugin for her.

yea fair enough, i really thought it was the other way round though. -9s being slightly bigger but better in design, therefore only a tiny bit more lag than the -7s but more top end..

i was fairly certain the -7s were the smallest upgrade turbos you could buy, but there is so much confusion around these turbos that i wouldnt be suprised if i had it wrong haha..

Wedge you know abit about this dont you?

The only difference between them that i can find was the exhaust wheel 1 was like 3mm bigger then the other or somehting like that. But i cant wait 3 weeks for -9s anyway so -7s will have to do im over all teh waiting and f**king around, just want it to run so i can enjoy the car.

yea fair enough mate.

just be easy on the clutch when you get it back, its generally the weakest part of the car from stock. and it is advisted when going with bigger turbos to upgrade it etc..

you doing anything else bar turbos and computer?

I'm not 100% sure but i believe the exhaust housing is slightly different design on the -9 too.

-7's = r34 n1 turbos

-9's ARE HKS GTSS turbos

The graphs i looked at when researching turbos showed <150rpm difference between the two (-9's been slightly worse), but the -9's usually had the better top end (10-15kw's), however this is highly dependent on supporting mods and i couldn't find any back to back comparisons (who's going to waste 2.5k to go from 7's to 9's unless the've blown a turbo)

TBH throw 20-24psi through either of them and your going to be making ~330awkw and absolutly exstatic. You can't really be disappointed with that.

Good stuff - that means all three of us a runing platniums.

all this talk of turbos is making me very keen for the next stage on mine..

seriously going to have to consider E85 i think.. have seen results with a similar planned setup as mine making 370awkw!

will be hard to pass that potential up i think..

Yep - I've been saying for a while i rekon it would be possible to crack 400awkw with E85 with 9's.

Someones 34nur in melburne made 379awkw with 7's (stock n1's) and E85 recently.

Yea I reckon 400 would be too much for those turbos... Could probably get a dyno to read it, but how accurate?...

I'm pretty sure both run out of puff around 22-24psi?...which would restrict huge top end power etc...

yea fair enough mate.

Yep, going to do mid pipe on my exhaust since the cat back is 3 and a half inch and so are the dumps but has the stock mid pipe, also needs a new clutch as mine is almost shagged, will do injectors and maybe fuel pump with the ECU, then after i have it all sorted in a year or so i may put a big single on it when i get another car as a daily, and go for massive power since the engine is built for it.

ohh and i hope everyone has taken the restrictor out of the side of the stock air box to, it just pops out 2 clips just use a flat head screwdriver, will double the air into the box, i can now hear my car sucking in that sweet sweet air as i thunder down the roads lol.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
