What Power Mods Can Be Done To Tune A 300 Without Supercharging Or Tur

[Adam Craig]

What power mods can be done on a 300 with a budget of about 2k? Not looking to supercharge or turbo though so any advice on other mods would be great.

Many thanks.

Here mate, this is a good tunning part for your IS300. Great price i believe:

What kind of gains can be achieved from installing that part mate?

Anything else that will boost the performance on a 300?

Many thanks.

Hi, you can gain around 12bhp. Have a look here the dyno charts with an SRT intake:

You could also fit a good exhaust manifold, decat pipe or sport catalyst and a brand name exhaust muffler.

to get power out of an n/a car you need to spend alot of money for the same results that a turbo/supercharger would get. alot of what you would do would also be done when going down the forced induction rute i.e. exhaust, induction and mapping. de-cating the car will probably give you the most from one single mod, thats removing all 3 cats. but its going to cost you a fortune in labour because the garage have to take the stering coloum off to get the manifold off. also you can not get the lexus ecu re-mapped, so its a chip/stand alone/piggy back. after that your looking at head work, cams maybe even uping the compression ration and for that sort of money you can get yourself a supercharger.
