You gained zero HP. spacer and polished TB did nothing. 1ZZ TB and mod your intake or do an intake swap plus complete exhaust from header to tail pipe you'll get a better throttle response. other then that boost or piston swap with fuel management. These engines especially the head is not designed for high performance but fuel efficiency. So unless you spend money to boost your gonna get disappointed.
Theirs no replacement for displacement!!!! |
