No doubt airflow, fuel supply and cooling have to keep up with the increased load. The motor can currently do 8.5-9K in short transients but whether the block, crank and pistons can take the load at higher rpms is something that needs to be checked out.
I'm just wondering what I could do to reliably raise RPMs on my current motor, which is a Toyota 2ZZ-GE. It currently redlines at 8.5K but I would like to raise it to 9.5K or 10K. I'm not sure whether this project has been undertaken before, so I'm doing my research.
I'm thinking of making some changes to the internals of my engine,namely:
1. Titanium connecting rods
2. Lightweight valve train
3. Heavy duty rod bearings
Would any changes to my ECU be necessary if all else is left alone?
Would I experience any increase in wheel horse power as a result of...
