Change the cam to one with a more aggressive profile, install a performance hi flow air intake system, hi flow mufflers and a set of exhaust headers, u will have to install hi flow fuel injectors and a re-program of the computer to take advantage of the above modifications. If u really want to go all out a Turbocharger would be the ticket, but that would cost $1000's

How do u adjust the idle speed on toyota 5a engine

Modern vehicles do not have an idle adjustment. However there are a few common things that can affect this. First, if check engine light on, you must verify any codes. These can point directly (or indirectly) to drivability problems. If there are codes refer to Toyota factory procedure to read an interpret. Or have someone qualified to extract OBD2 info with scanner. If certain no codes then often times build up on IAC (Idle Air Control) motor and/or injectors can affect idle performance and be a good start. Vacuum leaks can affect idle too, but these usually set a code...but not always. However other engine controls can influence it too. A MAF (mass air flow) sensor can be dirty or faulty and occasionally set no code in PCM. Otherwise have a professional drivability specialist monitor all sensor data to make a proper diagnosis.

Pls help me, I need to know the best ignition timing.

The faster time will give you the best performance but then you will need to use better gas if you have a timing ping when you accelerate.
