Is the V6 engine prone to oil surge problems?


Recommended Posts

How bullet proof are they on a circuit?

I remember the 2ZZGE requiring a baffled oil pan or/and an accusump system.

What else is needed to make them bullet proof for track abuse? (particularly the CUP 430)

 

Thanks,

On the 430 cup there is already fitted the red baffled oil pan as standard...

Other than that I can argue about the oem pistons not consistent quality

I had an engine failure on track on my 380 cup and after replacement with a new engine ( with some mods ) I had a piston failure that didn t make any engine damage.

the standard pistons arent exactly built for track use with that power so I fitted forged pistons and conrods.

Wiseco even recently revised it s forged piston design ( that was probably already ok ) for the toyota v6 to give more space between the segments as that s were the oem piston tend to break if stessed.

To be fair there are a lot of 430 cup even with a 460 bhp remap going on track without problems so maybe with the watercooled supercharger and it s specific map the temperatures are lower  and no eventual detonation etc...
