I have a freshened up T78-33D turbo for sale. Has little to no shaft play. This turbo is rsted to 750HP. Only selling due to switching to something smaller.

Looking for $1100 + Postage.

PM me for my mobile number and I can send pictures.

Located in Perth.

T4 (split-pulse) flanged turbo. 4-bolt rear housing. Trust don't quote an A/R, it's a 17cm^2 housing according to them, which is around the 1.00 A/R mark (correct me if I'm wrong anyone).

What's the exact front and rear a/r? And what would the turbo hit at on a rb25 with poncams PFC etc? I have a split t4 hks manifold!

As I said, Trust doesn't quote an exact AR on these turbos. On that setup and on a good tune I would expect to see full boost by 5000 RPM.

Cheers.

Mine looks quite similar in size to a Garrett t51r which is. 72 comp housing but t78 has 2.75" outlet, pretty sure the 17cm is around. 82 and the 22cm is about 1.10

    • As long as its NOT a HyperSHITtune, youll be fine.
    • First time visitor and currently getting ready to start work on my HK Premier.  Its all stock, 186 with 3 on the tree.  The only mod i have right now is extractors.  I am hoping to get some guidance on slightly modifying the engine to bring a little more power. Just going for a nice, comfortable cruiser.  The car is very straight, however i have been out of the country for 20 years and its been gathering dust at a family farm.  Will be doing quite a bit of body work to cut out some small rust areas (frnt quarter panels and a few other small bits) and fix up the paint.  Will be redoing the interior (its currently black and the seats are in real need of recovering and respringing the driver side (its front bench seat).  The dash needs a little TLC, but no real damage.  As my heater has degraded I am considering fitting something after-market that will be both heater/AC (recommendations here are always welcome). Wanting something discrete that will allow me to use the same controls and not be obvious once inside the car.   For the engine, i have been told i could consider upgrading my cam (imagine i would need a new head as well) and putting a new carby (currently the original stromberg).  However not sure what is going to be the best route.  Would certainly welcome any comments/suggestions.  As  a final step I am looking at changing the wheels. Current hubcaps are in dire need of refurbishment or replacement (imagine its a bit like hens teeth).  Thinking of some clean/classic looking mags (7-inch should be more than enough - not going for a large change in look).  Welcome any comments/advice and of course any questions. 
    • I got the ARC M079 due to the space constraint.  Been running mint for the last 3 years.  Plazmaman also seems like a really solid choice but not used myself.    Hunt around for a better price but this is what I have - https://www.rhdjapan.com/arc-brazing-intercooler-smic-m079-bnr32.html
    • Wanted to follow up on this. Did you end up getting the M073? Still deciding on what to get between nismo m073-79 and plazaman.
