i would say it affects the response of the vehicle more since the motor kicks in offering high torque. If its faulty get it fixed or keep it as it is if you can't afford. Transplant is going to cost you a bomb. it is not a 1 to 1 fit. your module, ECU, esp, harness, gearbox, safety system, gateway, body control module etc etc needs to be replaced or hybrid. basically its just taking a whole s450, gut 50% of its parts and replace in your current vehicle.

CT200H is heavy compared to other 1.8 vehicle like altis due to the weight of the motor and batteries. if the hybrid fails, you're just lugging extra weight.

You can strip off the hybrid system. but it takes alot of $$ and complexity to do so. there are alot of modules where the system communicates with the hybrid. Plus some of the cooling system runs to the back of the battery pack and any attempts to bypass or temper the coolant will result in error. My advise is to sell it or Swap it or Fix it. If you intend to keep it for a long run just fix it. the hybrid system is good. If you plunk in a turbo 450 you will cry. because the maintenance, fuel and transplant will hurt you alot. keep it if there's sentimental value. let it go, so that the new owner or enthusiast may put some effort into refurbishing it.

parts are not hard to find. there are plenty of OEM parts you can buy from local stores or import it from China. Prices are affordable. My advise is to maintain as it is. If you put in a 2jz, or another other motor, you have to live with a imperfect vehicle. many would think 2jz is a nice engine to put in. honestly, you should drive it daily they only comment. if you're aiming a drift machine or drag rocket then that's the ideal root to go. but for a daily commute, its not so pleasant to drive. infact you will feel its a downgrade compared to your previous setup where its much responsive and refined for city driving. not to mention the other things you need to iron off after you perform the heart transplant, like wirings, custom alignments. vibrations. balancing issues etc. In the motorsports world, those aren't much an issue because you just want SPEED and POWER. but on a daily drive, esp when you fetch people, these problems would shy you from driving it out on a weekend night out. You definitely don't want a unreliable hulk.

join those car groups with enthusiast whom know where to find parts and how to maintain them. I'm pretty sure there are alot of old folks would snag these vehicle as their retirement project cars.

get a lexus. scotty kilmer approves this
