Garrett Gt51r

[T04GTR]

as the topc states all you guys with a clue on turbos. im thinking of upgrading my t04z for my new motor.

ive noticed the gt51r on a few 1jz and was wondering how much in the world of lag wed be looking at???

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 .
