Which Turbos To Put On My Gtr34?

[Rizzz]

Hi

Im really confused as to what turbo's i should put on my gtr 34. I would like to reach an easy 350awkw.

I have 700cc injectors, pon cams type b 260in 260ex, cam gears, power fc, exhaust, and n1 oil pump.

What is a nismo rs581 turbo? Are they any good? looking at getting them! or go with the Garrett 2860-5's .

Any help would be much appreciated.

Regards Ross

-5 are what you want, those Nismo's are old tech stuff that will be laggier etc.

-5 are good for more like 380rwkw on a good setup, yet -7s and -9s are more 300kw material. Even 400rwkw is not out of the question for -5s

T517Zs with 10cm rear, better quality, tighter tolerances, better response and same power as -5s, ask your tuner

-5

Stock stroke?

Headwork?

If it's still stock capacity I think you would be better off with 9's and making a slightly lower figure. It's all good to say you want 'X' power, but when you get belted off the line by a much lower powered car you wont be happy!

2.8 to 3.0 with 5's yes

2.6... Not so much...

Having said that it does depend on what you want from the car.

What's the difference in terms of all the above but 8cm?

Ross, sent you a pm.

aim for better average power over a higher top end max rwkw

gt-ss or -7s would be better suited to make a quicker overall car

stay away from the nismo's they are older spec

and don't forget a fuel pump

Ye for the sake of 10-15rwkw, I'd get the smaller turbos every day off the week.

If you want me to take you for a run in my car Ross let me know as i have -5s

I did have -9s previously & for a street car i'd strongly recommend you get -9s.

i to am confused over these turbos, everyone one here says gtss's for standard engine.. but from memory they are not much good over 300kw... that seems abit crap considering my standard r34's are makin 270

also lag, might be a problem of the lights in a car with grip, but my silvia is useless in 1st and 2nd andyways, so i could not see it being that bad.. unless anyone has experience with -5's off and on throttle/ would be a problem for drift....

i just think is pretty damn dear to pay 3+k for turbos that are only goin to make and extra 30kw? not much headroom for when u get bored and want more power....

sorry for thread hijack...

[R31Nismoid]

I really don't know how people are still getting them confused with the capabilities. There is sooo much information...

-7s / R34 N1 = 300rwkw

-9s / GT-SS = 320-340rwkw

-5s = 370-400rwkw

-10s = 400rwkw+

It's not expensive to pay 3k when you think your stock turbo's, can & will lunch a motor if you lean on them too much. Whats cheaper? Turbos or a motor rebuild?

And it's not just about peak power either (of which your statement of only 30kw is wrong), its the midrange bonus you also get which the factory items lack.

So -9s will actually give you closer to 60-70rwkw up top - and MUCH more mid range whilst maintaining brilliant response, can't ask for anything more than that really and for 3k, it's the best value you'll get for a streeter. Add in some cam gears, exhaust, clutch & tune... The result is one mighty quick GTR around the street and occasional track visit.

Sorry but off the lights a Silvia isn't in the same league as a GTR. Even with 350-360rwkw I get almost full traction in 1st/2nd once the tyres have some heat.

[GTScotT]

Ash, not to step on your toes but I am honestly yet to see a wealth of 330kw -9s.

They definitely seem to be an up to 330kw affair but much more of an 'over 300'. There would be a magic recipe to doing it but its not what avg joe should expect when buying them.

I'm just throwing it out there... I think their good and that's what id get but id certainly stick to -5s for anyone dreaming of 350+

[GTRsean]

Peak power, peak this peak that.

Area under the curve is where it's at, I know because I've had both styles.

Good luck with your choice

Ross, sent you a pm.

the 10cm has bigger rear housing for more topend power, the 8cm is more for response and max out at 330-350rwkw as the 10cm i've seen go 380-390rwkw
