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 :nyaanyaa:

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 :nyaanyaa:

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 :(

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)

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

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

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

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.

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.

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 :P

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

    • Tape some wool onto the vent then take it for a drive I did this to my reverse cowl and was instantly unhappy, as anything over about 60kph would have the wool enter the engine bay, thus just adding underbonnet pressure and stooging my coolant stack, it did let alot of heat out when stationary though, which really didn't help once the car was moving, with the reverse cowl you could watch the coolant temps cheap up the faster you went on the hwy, I assume it would be alot worse doing track day speed With the vented bonnet (just after the radiator and about 1/3 up the bonnet) on my old R33 the wool on the leading edge sat at about a 45° angle as air poured out of it From looking where your vents are, and their size, I believe you should be fine at speed and air should be evacuated from the engine bay, I think it will be a night and day difference when stuck in traffic though for removing the trapped heat, and not sitting there cooking when parked up after driving around... #convection  Post wool tuft pics and data for science  This beastie is one nice and unique rig, enjoy
    • It is possible to do this stuff for "cheap". But you need to be able to get deals on all the bigger items, and it really helps if you're fully capable of doing your own work. As soon as you're paying retail for new parts, or buying "kits" because you can't fabricate necessary bits and pieces, and if you really need someone else to take the reins of doing the work because you don't have the space/time/skills/confidence to  rip deep into the car and put it back together in a working fashions.....then you pay. And these days, pay means a lot of money. You'd think things would get cheaper, but they don't. They just seem to keep getting more and more expensive.
    • It’s almost the price of an engine build, you won’t have anything to bolt onto it though 
    • Hopefully it's enough to help with the temps! I was also only shit stirring, regarding Murphy's Law basically. I've found, what ever spare parts I have, are the parts I don't break. Ever. Also have never had issues with oil/spinning bearings until I put oil pressure gauges on the car. 😛
