TRD S/C & engine life? Ordering soon

My question is just that, any tuning experts out there that can give a healthy estimate on the engine life of a stock block, seriously. More specifically, with how I plan to drive my car. I will put 20K highway miles a year on my car and useally don't get on it to much in terms of beating my car but I like to have fun. My car has 11k miles on it now and I've only redlined it twice. I'd like to think the engine will out live most of other components but I'm no mechanic. Please tell me I can get 150k out of a TRD S/C TC before I go buying this thing (I know... no guaranties). Just asking the guys who know this kind of thing. Thanks a lot for any info.

Also picking up a Fidanza flywheel & a CM Stage2 kevlar clutch, if I go S/C. I know it's a lot of money but that another topic of discussion.

keep up service and dont beat it then it will last

well, the simple fact of science is that more power will generate faster breakdown. Theres no way around this. a 100% stock tC engine that recieves the same care as a SC'd tC engine will last longer.

HOWEVER!
the supercharger system will most likely need a rebuild before the block goes out, assuming that you don't abuse the car. so youll have to worry about that before worrying about the engine.

If you really baby the supercharger system [which is very unlikely since its so fun to drive] it SHOULD last you somewhere near 150k miles without having to rebuild the block and its internals.

Yes, we do have Camry engines in the car, but they are by no means a 4G63.

Well, driving all highway and needing a comumter car, I might just get an intake and call it a day. Then again, a new engine or rebuild is cheaper than a new car. There's probably going to be a new tc or something that looks similar to want to buy at that time anyways. So for anyone who has ran forced air in their past cars, did they last a while? I just don't want to be faced with the decision of buying a new car within 5 years and 100k miles. I had 54k miles after the install of a t3/t4 turbonetics kit and a total of 82k on my old b16a (del sol) running 8psi with absolutely no problems. I hit a deer at 75mph, spun out, and rolled it. So, I didn't get a real chance to see how long the setup would have lasted. I know people that have 230k miles on their orginal camry engines N/A but this is still a foggy area for me with F/I setups.

None of us know absolutely for sure how long the TRD supercharged tC will last at this point because its still a new platform, but based on what I've seen with other toyotas you should be fine for at least 150K. Older toyotas like the supercharged MR2s, the turbo MR2s, and other factory boosted toyotas have all been very well built cars so I think our tCs should be fine as well :)

The TRD Supercharger is covered by your factory warranty, it'll last a long time if they're willing to put it under warranty.

Since trd did their homework when building this kit getting 150k out of your car should be no problem. Especially because a supercharger is generally easier on a car than a turbo kit. However most of it will depend on how you maintain and drive your car. Also I would suggest not buying a fidanza flywheel. They are a poor setup. Seperate friction surface from the rest of the flwheel. You have a steel friction surface against an aluminum main section. Just think of the issues with heat and expansion. Being a former dsm owner I have seen first hand the fun this creates. I would suggest looking for a chromoly flywheel instead. If act has one out it would definately be worth it. And check to see the weight. For every day driving I would personally go with a 11 or 12 lb and if you are heavy into racing especially autocross then I would look at 8 lb. Just suggestions take them or leave them.

I've been wondering about this myself. Whenever the auto s/c kit comes out I'm looking at getting it, and I was also thinking about maybe adding the ZPI s/c pulley and new BPV to add a little more power.

Anybody out there have any opinions on how bad those are for the engine?? I want the power, but reliability is more important to me, so if the pulley and valve are gonna significantly reduce engine life, I'd rather stay away from em'.
