either way you would be best off getting a tune with it
so i'd go the bigger, but that might require bigger injectors+fuel pump etc
not sure on the spec of those turbo's tho

Avoid those turbos as there is extra gear you need to get it running on an RB25. Get the stock turbo rebuilt and it will be much more reliable and more importantly, a better ball bearing cartridge core = less lag.

You can buy better genuine Garrett ball bearing turbos for so cheap these days it's not really worth going for a KKR.

I think you can get a GT3071R as a direct bolt on with internal gate. It would go quite nicely on a mild tune RB25.

if you want to get one of the two i would get the smaller one because it will have less lag

GT3071R from Garrett as a bolt on replacement for the RB25DET R33 can be had for around $1400 if you shop around, the compressor dynamics are vastly superior to the KKR430/480/560 and best of all, the GT3071R is rated to 550Hp for the RB25DET and retains a ball-bearing core. KKR's do not use BB cores sad.gif

Getting the stock turbo rebuilt can be done for less than the KKR and still provide more power as well.

Ok, KKR 430...talking from experience was fantastic for the price i paid , but the hypergear one is aroun the same price but gives you 12 month warranty instead of a 6 month on the KKR. At the end of the day ya prolly will onlyhave the car for 2-3 years which it will suit it purpose

sweet as, cheers boys. the best price i got for rebuilding the standard turbo was about 1250 and hi-flowed as well was 18hundi.. so i just thought a brand spanka would be the go. but ill look into that gt3071r.. and also whats the go with some being only oil cooled as opposed to water as well.. are the oil cooled only ones as good??

Get a turbo that is oil cooled and water cooled, otherwsie your engine oil is super heated by the turbo and returns to the sump very hot, which can cause oil longevity issues among other things.

I would be getting a few more quotes on the rebuilt turbo unless that includes removal and fitment.

We can build you a internally gated TR43i .63 Turbo if interested. It will be able to make 300rwkws on the RB25det with very good response. We can also hi flow your stock one to 500HP.

Post #12

internally gated TR43i we can do them for $1000 each brand new with 12 month warranty doesn't matter how hard you boost or drive it. and to high flow your stock turbo to 500HP we can do it for $750.

below is a photo high flowed 500HP T28 we did last week:

wheres your workshop at mate? how long would it take to rebuild mine? and are the hypergear ones ballbearing?

We are based in Melbourne Brunswick. The high flow price we quoted you earlier is with sleeve bearings.
Ball bearing CHARS will cost you additional $700 as there are lot of machinery work involved to have it fit into stock housings so probably not worth doing.

A friend of mine with same mods as you bought a KKR560. Makes full boost at just under 4000rpm. Had issues with the internal gate but just got an external gate and solved the issues. Everything bolted up to standard location. Was a cheap turbo upgrade. There is nothing wrong with KKR's but all up to personal choice and how much you want to spend. As far as I know, the old KKR's were only oil cooled but the more recent KKR's are both oil and water. With 550cc injectors, fuel pump and a tune you could make your 300rwkw with the KKR560.

if you buy a blown jap s15 t28 or a n1 gtr turbo or any t28 with the 6 bolt rear housing banzai on the coast can put any new genuine hks core in it for the 1100 mark much better turbo
