Kkr 430 Vs Kkr 480

[ian_and1]

ok cut a long story short, have recently just installed a KKR430 on my car, now we have been having a few problems with the KKR430 just not been up to scratch, so it's getting sent back for a new one, now they have asked me if i would like to go up to the 480 ? just wondering pro/cons with going to the 480, it will be on a R34 neo, any help would be great thanks

KKR 430

And what didnt the search button answer exactly?

Being there is a 8+ page thread on the 480...

Being more specific might help for a better answer... otherwise i reckon the other thread will almost certainly answer your questions

from my experience there are no pros for the kkr turbos. i have had too many problems with them in such short little. such as internal wastegate jamming open, oil seals on the turbine shaft failing. i bought it brand new, and no later than 1 month, i had to send it back cause the wastegate had jammed open, was only running 14 psi. no sooner had i put it back on, within a month i had to send it back again to get the seals replaced. and only 3 months ago the seals went again, so i threw it in the rubbish and spent the money on a garrett gt3030r which is what i should have done in the first place and saved a lot of time and hassles.

i'm not saying all kkr turbos are them same. but i am not buying one ever again.

they are just cheep chinese turbos.

you get what you pay for here.

if I had the money to upgrade I wouldn't be keeping mine either

Well the info is all there - you've gotta look @ the results, and decide what you want.

No-one can decide for you really...

ok let me get this straight.... u own an r34 gtt and u brought a kkr..... for shame

[l0WRB]

simon is correct lol shame on you

i own a kkr480 have for over a yr n half now runs 20psi daily and done over 25,000kms

but if ur not after lagg then i wouldnt get one i dont see 20psi until around 4500rpm or bit later

and they are only good for around 240-250rwkw which isnt much power at all....

sell it and get a decent turbo! cause ur only gonna run into more troubles there biggest one wastegate issues.

haha would love to sell it and not use one but as not having much money at the moment sort of restricts what i can do cos i have to change the dump etc over again and that's gonna cost more money

[paulr33]

decent power & not much lag & KKR turbocharger

is a contradiction

sell the turbocharger and buy a well proven unit

HKS 2530, HKS GT-RS, Garrett (many equivs), and so on...

sorry but you wont get what you want with the KKR range

and the 480 will have more lag (ie; larger housing and wheels)

[bozodos]

I have a KKR 480 (on a RB25DET), and it sucks arse. I'd be looking maybe a Holset or a Garrett replacement for mine, and given that even highflows can make around the same power as these, why would you bother?

Surely you'd almost be going backwards with a NEO motor and one of these turbos as well!

did you get it from ebay or otomoto and how much did you pay

[l0WRB]

only place that sell genuine kkr turbo's is otomoto all them ebay stores are ripoff's which = junk that will fall apart/break in first few weeks/months

[ian_and1]

well found out why the turbo was *extra* crappy the waste gate hole was like a 16mm but ment to be like 25mm ?

like i said before i *know* they are not that good but with not much funds atm gotta make do with what i can

[wannaslide]

yeah thats why i assked

From my experience with the kkr's, the ottomoto ones aren't any better. I replaced a new one one twice whilst on the dyno, and it required extensive mods to make it hold boost.

[wannaslide]

i have heard some good things about them but probaly more bad there must just be some lucky peaple that get the good ones

[skygtsnt]

did you get it from ebay or otomoto and how much did you pay

i got it from otomoto and i think for memory i paid around $1000 that was for turbo and the dump pipe to suit rb25det. i had kkr 480 and they are so laggy its funny. seriously.

[ian_and1]

i have heard some good things about them but probaly more bad there must just be some lucky peaple that get the good ones

yeah i hear very mixed results about them

i got it from otomoto and i think for memory i paid around $1000 that was for turbo and the dump pipe to suit rb25det. i had kkr 480 and they are so laggy its funny. seriously.

yeah think i might just stay with the 430 for the time been

yes holding boost is there bad factor aswell as being very laggy and not making that good of power..

best bet is to run a 50mm external gate straight off the scroll then u wont have any dramas

there a cheap turbo for 250rwkw though but id go a gt35r or gt30 anyday over it if i had the chance again lol

[skylinekid]

wats ur mate running.. is he using a kkr aswell justin
