Which Is Themost Efficient Turbo For Standard Rb20det

[mtopxsecret6]

I'm looking at what would be the best turbo upgrade for a standard rb20det with supporting mods. The decision is between an rb25 turbo standard/hiflowed, or a HKS gt2530. I have read lots of rave's for both, though i would like to see what peoples thoughts are on the differences between the two turbos. I'm looking for mid to top end performance. The car will be used for track work, so low end day to day driving isn't to much of a concern.

if you are going to change the turbocharger and do track work forget the std r33 turbo

either highflow or hks 2530

both will have steel wheel rear which is what you will need

depending on the age too, may want to reconsider re-balance and service

its probably likely the highflow is newer than the hks 2530 given they are quite old

so i guess less risk with the highflow
