Rb26dett Rebuild Needed!

[CRZY32]

Engine/Car: R32 GTR 93

Type of failure: Rear turbo wheel exploded under boost. Ceramic fragments are causing knocking sound and very low compression (90psi) in cylinders 4,5,6. Not yet fixed!

Factors influencing the failure: Just picked up car from docks with Apexi AVCR boost controller. Unsure of boost level, was running fine until it was pushed past 5000rpm. Then BANG!

State of tune of the engine: Trust intercooler, Mines ECU, HKS pod filters, full 3" exhaust, Apexi electronic boost controller, Blitz BOV's..

General comments: Very unfortunate, turbo blew before the chance to dyno tune. Car in very good condition (85,000kms) full Jap service history. I'm guessing boost controller was to blame for high boost (although it only displayed 0.65 bar)..

ANY SUGGESTIONS ON A BUDGET REBUILD OR REPLACEMENT? (CONSIDERING STANDARD NISSAN PARTS WITH UPGRADED TURBOS...)

HAS ANYONE EXPERIENCED THIS?

ANYONE KNOW WHAT INTERNALS WOULD BE AFFECTED AND WOULD NEED REPLACING/REPAIRING?

Yeah its not uncommon for the standard ceramic turbos to let go and lodge bits of itself in the pistons... Bit wierd that it happened only on .65bar... you'll need a full rebuild... may as well go forged pistons and the extra stuff while you're at it... budget around 10k....plus turbos

Any idea on the exact parts that may need replacing?

And other parts that need attention (maching/honing/balancing, etc)?

Also looking for workshops in Melb VIC that can rebuild RB26DETT's..

I was considering a rebuild with standard internals but low mount HKS turbos.. Would this be much cheaper than forged pistons and aftermarket internals??

Thanks for any advice..
