I have a 2003 Lexus is300, has 180K miles.
Its my daily driver to and from work, driving about 70 miles daily throughout the workweek. I've had it for over 100K miles and it's been nothing but great to me, I've kept up with its services.

It's my turn to return the favor, I want to rebuild my motor, and while I'm at it.. get it up to 300+ horsepower (just to be able to get on it and feel a little power every once in a while) I know it'll be a little spendy, but it's a well matained car and interior is awesome. It's a car I plan to keep for a long time, and I do own it outright.

what do y'all reccomend to get done? Motor rebuild? Headers? Exhaust? And what sites do you buy your car parts from..

any help would be much appreqcieted.
Thanks in advance.

You can get GTE rods and pistons but OE will be fine at 300hp.
But if you're doing internal motor work i would look at getting a turbo kit tbh.

Not really worth building these N/A IMO.
