Which is the Best OEM turbo?

[Chronox2]

I will like to find out which Nissan turbo is the best. I know that the S15-R turbo is the dual BB and is the best of all nissans cars, but what about the Gtr and other cars. All I know Is this turbos.

S15= GT2560r Good for 200-350hp
Z32= T22/B02 Good for 200-220hp

Correct me if I'm wrong, also Fire Suit ON.

No input on best Oem turbo?

[dreadedfist]

They'll all suit different goals. A stock t25 on an S13 is going to be a great turbo for 200whp, etc. Ceramic turbos are great on street cars that aren't power houses, just run them richer if you're doing long drawn out pulls that up the EGT's significantly. Again, all comes down to what your power goals are and what you want to do with the car.

best nissan turbo for drifting? haha

[Sileighty_85]

S15 is best bet all other Twin Turbo engines use small turbos about the size of the T25

[EsChassisLove]

S15 series.

GTI-R T28 ... even when hybrid with S14 turbine housing.... makes 300 easily and spools decent and you can rebuild them not being BB

i have a GT2859RS .64 ..
It is off the R34 N1 Skyline. Best IMO

I got a friend with a s14 that just got in to nissans, and I'm a z32 guy with a TT. I got 2 used z32 turbos from a manual vg30dett (A/t and 5sp are different) they are tiny cute little things, so he wants a cheap OEM turbo to work with the Ka, and I'm doing this because I was researching for some good turbos for my Z.

So far N1 are pretty good, but how much Hp are they capable of?

Specs on the gtri turbo?

[Chronox2]

So I decide for the gtir t28, but I bumped into 2 different A/R one is .80 amd the other is .60. Are there any different beside the compressor housing and air ratio? Im buying the .80 from friend in FL.

the guys said it was from a GTIR, but there was a wagon car from nissan that came with the GT2551R "so call GT25G in japan, and in other parts of the world GT25R" from all the stuff i had collected. this guy was charging me 100 for the turbo, Y pipe, manifold but the turbo had some shaft play. so i said no, and some one local is selling same turbo for 80... but since i need 2 of them and they are BB.

i look on the garrett website and it is BB. im looking for a turbo that will get me to the 300hp "single"

[TheRealSy90]

GTIR turbo is the best oem t2 flanged turbo available, if you are just talking max power. Throw it on an sr with aftermaket cams and haul ass.

[Chronox2]
