Message after fixing all boost leaks
checking timing belt
setting CAS and tps
having no codes
not being lean on the dyno, which means the fuel system is okay, and not being rich which means the boost system is still tight at 15+ psi i cant suspect a fuel pump or anything fuel system related.

Id like to double check with CAS timing and check the turbos' compressors' blades

just cause a turbo doesn't smoke doesn't mean its not bad. Because of shady installations Ive seen bolts go through the compressor wheels and even sit in front of the wheel chewing it up over time. Still spins but doesn't move air.

He also stated to me that it seemed like the car just got slower and slower slowly IIRC, its a possibility because of the above.


as for the turbos, i cant see why compressor wheel nut cant be removed, remove the compressor wheel, and the shaft and turbine wheel cant be driven out of hks' chra and inserted into a new chra. I wonder if thats what HKS did. when rebuilding hks turbos the idea is to retain the turbine wheel with extra blade, and hks' custom to-bolt-up-to-vg30dett compressor housings.

But if HKS specific chra with the extra turbine blade are available that would be breeze.

IMO aside from new gtx28 series, the hks 2530 was the best all around turbo, the jwt700s alone are killer with breather mods
