Hi everyone,
I'm new to this forum and I would like to say hello to everybody on this website.
I have a question regarding the turbo on my 4g63 engine, which happens to be a TD05H. I am wondering whats the difference between the TD05 and the TD05H?
How much boost can the TD05H handle and what is the rated horsepower? At the moment I'm running 15psi but would like to go higher as I have just installed an aftermarket ecu.
Thanks heaps as this has kinda got me stumped.
Ivany.

AFAIK the H in the TD05H could be Hybrid or Hi-Flow, if its Hybrid then the inlet is larger.

TD05 is the size of the compressor housing. The stock turbo on your car is probably a TD05 16G turbo. The 16G turbine can flow around 22 psi or 1.50 Bar at redline. The TD05 can handle as much exhaust gases that you can throw at it. The engine is the one that has it's limits.

Adding an aftermarket ECU may not be enough to be able to start raising the boost levels. You will need to start upgrading the fuel system before going above 17 psi safely. An upgraded fuel pump and larger injectors will allow you to max out the airflow of the turbo reliably.

An EGT gauge is always good to have to monitor air fuel ratios. Just keep the temps below 900C.
