then use a silicone bend and a metal connector tube to connect the hybrid inlet to my modified silicone tip, that way no new boost
had thought about it, but would prefere to avoid it.
i`m unsure exaclty what the benefits of the 360 deg bearings are, i just know theyre better. thats good enough for me until i find the time to read up one it :wink: i would also take into consideration, it may be worth sending the newly built core off for high speed balancing before you put the housings on and use it.

@ wolverine _ souldnt be much, but gives you peace of mind...

heres an interesting read, though when he mentions the k03s turbine housing, i think he actually means k04-001.

The A/R ratio is the ratio between the cross-sectional area (A) of the turbine scroll at any one point and the distance or radius (R) from that point to the center of the turbine-wheel. This ratio is always constant so each point along the turbine scroll will have the same A/R ratio. A turbo with a smaller A/R ratio will tend to create more torque while a turbo with a larger A/R ratio will provide more power because more exhaust gas energy will be acting on the turbine-wheel. Generally, an A/R ratio of 0.7 will provide better low-end response, while an A/R ratio of 1.4 will provide more top-end power.


Basically a ko3s compressor housing will give more torque and less bhp but in fairness in you're not going to really loose that much .

would be easier to bolt the k04 onto the k03, not sure the gains would be great though...  :undecided:

true, but i dont think it would be alot more over the k03s.

lol, thats not what i meant.. i meant i dont think a k03/k04 hybrid would give much gain over the k03s. the k04 bolted on would give alot more top end power but less low end torque. so, would be less drivable as a daily.. i had thought about it but for what its worth and the route i am planning i think full k04 internals in the k03s housings would be a better bet. if i could get my hands on the k04-001 for peanuts then i would hyrbrid that but its not going to happen..lol
