seriously.. I am quite noob about turbocharger model and spec such as RHF4, RHF5, TD04-11G,-13G, -13T or -16G
But thx to you now I made up my mind not to rebore and just go for BoT. BTW, for RHF4 which spool faster, will it cause any problem while driving at highway? I worry later a slight movement of pedal will cause the turbo to spool in till my engine overheat.
As for TD04, normally around what RPM it starts to spool in?
I worry later outside foreman simply mod in some turbo for me which causes unpleasant driving... I just want to use a smaller intercooler like those GSR which can be install at corner of the bumper to stay low profile.
RHF4 have lesser output power but it will assist low end very well, the boost will end at 5k RPM. It is a very safe turbine for your car furthermore the turbo is cheap now. RM200-RM350 can get easily. Highway it would be fun... trust me.
Remember always cool the turbo using oil and water, some workshop just fit oil cooling and they say dun need water. dont listen to them.
Most of the turbo had Oil cooling and water cooling path for better efficiency.
For BOT try to use standalone ECU, piggy is good to play around but for long term i would rather go for standalone for a stable and a safer ride.
