-7/9s Or -5s Garretts

[Nee-san]

Wonder if you can get electric cam gears, map them to load points in the tune. Now that would allow for some very good gains. Basically be an aftermarket VCT/VVTi

Only problem is you'd probably need a motec to tune it effectively.

HKS VCAM ?

[R31Nismoid]

Yep BWRGTR - cam gears

Less than $300 even

Just use a NEO head, poormans HKS V-Cam

Obviously doesnt work as well, but you still get the VCT bonus.

Only issue is you need adaptor for the NEO head to get the 26 plenum and so on (and some porting)

Two profiles is barely variable cam timing, you want it to be continuously variable and to be able to vary between more than two settings.

I guess it is better than nothing though heh.

[R31Nismoid]

Well it helps with the lower end, which is the ole sticking point of the RB26 in many respects and lets you get the top end also!

So for the cost it's not "too" bad if you are doing a build given you sell off your head etc.

Of course lovely v-cam would be the best option, but @ around 5k... it's not the most affordable solution

[Rolls]

Yeah might as well just get a completely different 6 cylinder for that price that already has those sort of features built into it. Pretty sure the VQ35/37 do it.

But then God would send a great flood to punish you for your sins and yeah Nismoid is right, if you know where to look you can get HKS or OS GIKEN cam gears for 300 ish.

Quick question regarding the -5 turbos before mine gets tuned.

What boost pressure on a rebuilt rb26 can the -5s max deliver before they start becoming inefficient? Car has all the supporting mods including B type poncams.

Thanks

[R31Nismoid]

Plenty have run 20-22psi easily enough on PULP, some have run more.

To many factors to save for certian.

For the Turbo Guru's out there when we are referring to the -9's are they the GT2859R-707160-9 model that Garret Lists

I am trying to get pricing on a pair for a GTR

I know the -5's and -7s are the GT2860R - 707160-5 & GT2860R - 707160-7

thanks for the help.

Should I be doing turbos on my new car? its got 80,000 on the clock and I was going to take it into Trent to do power fc / cam gears timing belt service / and basic stage one mods.. would you guys recommend I get trent to do turbos at the same time? how much roughly extra would it cost and am I right in saying it would make about 80kw atw difference?

edit: sorry if i seem noob new the the rb26 game

[R31Nismoid]

250rwkw is around what you'd expect stock turbps, and then 300rwkw on a unbuilt motor which is nice and safe

overall cost would be around 4k for the lot including turbos/labour/fitting/gaskets etc.

thats not including front pipes (if you don't already have them done, thats more cost)

If you're going to put new pair of turbos, you may as well do the clutch while you're at it (unless you've got one already).

As for you putting the turbos, it all depends whether your standard turbos have sign of letting go or you're power hungry that standard turbo couldn't provide.

That said I've got GT-SS in mine and at 302rwkw it may sound fun but I want more.

Yes Ash is spot on around $4-6k is what you'd be looking at upgrading to bigger turbos.

I should really put up my dyno sheet.

Also looking to find the answer for this. Trying to buy the HKS GT-SS equivalent

[Count Grantleyish]

Last time I enquired about GT2859R 707160-9 would cost me $2.6k for brand new pair without actuators.

From Rotormaster in Melbourne if I recall.

[J - Rad]

I'm trying to find what the turbo is actually called.

I've found about three different ones from

GT2860 -9

GT2859 -9

GT2560 -9

http://www.gcg.com.au/index.php?page=shop....1&Itemid=53

[R31Nismoid]

Depends on who's site you use. Garrett changed labelling a while ago as well which didnt help so some sites are not updated.

Seems at times American sites have them labelled differently as well.

The GCG link is correct in AUS.

[J - Rad]

Well I'll be buying them from MTQ here in Adelaide. Guess I'll just ask for Garrett GT2560 -9 /707160 - 9 then push the point that I want the HKS GT-SS equivalants for my GT-R. Hopefully they order the right ones.

[R31Nismoid]

Just give em the cartridge number, always get the right one that way.

Shop around, I've found MTQ sometimes to not be the cheapest (same for GCG)

prices seem to vary as much as $100 place to place.

Getting them for about $1,200 per turbo so I doubt I'll find them cheaper.

Haven't read whole topic. Just inputting my 2c.

My old R32GTR has Hks2530s -5s and is making 478awhp at 22psi, full boost by 3500rpm.
