I have an old school turbo kit on an RB26DETT I am getting, thinking of updating the turbo same time with a Precision Billet Turbo of similar power in the same twin scroll fashion but want to know exactly what I have. It has a Garrett A/R 84 and an HKS Exhaust housing with either 0.80 or 0.90 stamped on it. What is the powerband and what model turbo is it? Engine is equipped with Sard 700CC injectors, N1 272 cams, Upgraded ITB's, HKS bottom mounted cast iron mani with a big HKS external gate to the top. The Downpipe is a huge 4" setup and the turbo even though old is pretty big. I am yet to have a proper look but it seems to have a bit of work done to it like extended sump, a 24U block etc. Can someone chime in as to what size turbo it may be and powerwise?

TA45 rings a bell. Pretty sure that's what came with the rb26 kit.

Though the turbo could have been changed any time in the last 20 years as it's unlikely the one that originally came with the kit is still alive.

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
