I presently drive a 1997 Ford Thunderbird with the 4.6 OHC engine with 190k miles. I have always loved the SC 400 and am really interested in owning one.
The only thing that worries me is I think the SC's engine uses timing belts instead of chains like my Ford. Is there a conversion kit for this? How many miles can you get on a set of belts? How much to replace them? If one breaks will it kill the engine or does it "run free"
I don't think it'll kill the engine cause Toyota's don't use interference engines (which is when the piston and valves move into the same place but at different times).

The sc400 uses timing belt. I've heard people driving on the original belt for over 150k. I think the recommendation for timing belt change is either at 90k, or 120k, I forget. As far as interference engines, I think the 92-94 are non-interference engines, and any year above that are. So if you have a late 90's model and your T-belt breaks, good-bye engine.

Also, if you want reliability, the sc400 engine is very reliable. I've read somewhere that when toyota first built the engine, they built it to handle like 400-500hp, but detuned it down to 250hp for reliability. That's why you rarely ever hear of a 1uz-fe engine failing. I've never heard of one failing yet, knock on wood.

That's like having 80,000 on a normal engine. It's not even broken in
But Razo is the real expert. I should get him in here...

just some info on the sc400, its highest horspower point is at 5400 rpm. first gear is short and is great for take off,
back on subject a timing belt costs between 40 and 50 bucks im told.

man I would trust my SC 400 over a ford thunder bird any day!! The SC 400 is a very reliable car you just have to make sure that you get one that has been taken care of. And yes the car doesnt have a timing chain no big deal kinda wish it did but oh well. The timing belt is cheap to get but to change it with water pump tensioners and seals get expensive cause of labor. But this is done every 60-90k and you can always take off the covers with ease to view the conditon of the belt. I have 165k on my SC400 shes still strong.
