T51R is what HKS call their versions of the Garrett GT42R , T51R KAI is similar to a GT4294R and T51R SPL similar to a GT4202R . Cartridge wise the main difference is that the HKS options use that 82mm GT42 turbine in 76 trim and Garretts market versions the 82mm GT42 turbine in 84 trim . HKS have also optimised their housings for petrol aftermarket apps .

First thing to know is which TO4Z ie HKS or Garrett marketed version and is it worth a try on the new engine first . What power characteristics are you trying to change ? What things are different about the new engine compared to the existing one ?

Also between the TO4Z and GT42R families is Garretts GT4088R which is worth a look .

Cheers A .

      For fuelling the Haltechs have O2WB fuel controllers. Very useful for helping tuning VE and correcting for *small* mistakes. Of course if your injector/cam/trigger/sensor data is just wrong (or for a GTT which is not a GT) then you will get impossible reactions to things. I am sure you know this already but the reason people don't typically put haltechs (or any Aftermarket ECU) on GT's is because there's practically no real gains to be had - So this knowledge won't be commonplace.

      Can someone tell me if the cracks seen in the rear sway bar bushings in these photo's is unacceptable from a roadworthy point of view?

      Shouldn't need a "base map" for anything other than guidance to ignition tuning. You just need the engine capacity right, the injector size right, and something, almost anything, for a VE map. On an NA engine, fuelling is almost completely a function of load signal & rpm. It should run and drive with a completely flat fuel map. It will be too lean under load, but that's easily fixed. We used to tune all ECUs without any base map. There were no such things (until someone had tuned a near stock engine on one, and then they had a "base map".

      What did you actually buy/how much did it cost? When I got mine in like.. 2017...? 2019? the aim was to run Torque for gauges via ODB2 and things like Track Addict/Laptimers/Dashcam/Reversecam/Spotify etc. Mine never broke, but I wonder if you've got the same needs (it sounds like it). Cause I liked the idea of being able to do anything with it. That said, yours also cost 3x the cost of what I spent so... food for thought.
