hey mate...

a mate of mine had one on his r33-gts-t... pulled about 230rwkw... although it was a bitch to put on and didn't last too long... i know they are cheap but ur better off gettin somethin like a garrett and it will cost u much less in the end...

although some ppl have said good things about KKR and have had no problems with them yet it's just a cheap alternative i guess.

his mods were as follows: bigger fuel pump, fuel pressure reg, bigger injectors, boost controller, fmic, apexi power fc, exhaust, pod... was running about 20psi... still using stock afm so it woulda pulled abit more with a z32 afm...

turbo lasted him bout 1 yr... now he's upgraded to garrett...

As said above some say there good same say bad.... Ive seen one of these on an RB25 make around 220rwkw on mild boost around 1 bar. One of my mates used to have a 2535 on his RB20 made around 250 rwkw but ran a lot of boost i think around 1.3 bar.

Personally spend the extra $ and get a decent Garrett or HKS turbo.

i looked into it... but ur spending so much money anyways, u may as well do it right the first time... cheap turbos are good for the first 10000kms... after that forget it

ive got one on my cefiro, made 200rwk easy, only thing stopping it from making more is the injectors. pulls hard once its on boost, its been going strong for 2 years odd now :) . i cant see why it wouldnt make 220-230 ish rwk with the right supporting mods :D

speak to str8e180.....

he's the turbo god! lol....

however i'm running a 3076 .63 rear and full boost is around 39-4000rpm... i'm at 220 however my tune is beyond rich!

i'm getting it fixed next week and should be good for 240ish.... then the bottom end becomes weak, turbo is good for much more but motor needs to be strengthened....
