low turbo boost?

^^^^ if you run 6 psi you WILL be safe. i run 8-12 depending on the driving situation. and the only real reason i built my motor is so it can handle the 12PSI, if i was going to stay at 8 then i wouldnt have worried about it. jsut think to yourself: you already have another daily driver, so you shouldnt have any down time. at 6 psi with a turbo you can run about 247WHP, with 7 PSI that the TRD S/C uses you only put down 195WHP. 50+HP off 1 PSI cause the turbo doesnt use power to make power. its all free. dont buy into the crap some people will give that a S/C is soooooooo much safer. when it actually puts more strain on the motor. i have been doing this for 8 yrs, so i think i kinda know what im doing. not to mention i have 20K+ miles on my turbo set up with NO problem whatsoever. also you can get a ZPI kit for $2850, or the TRD S/C for $4000. you do the math

And when something goes wrong with a ZPI kit and toasts your engine, how much does ZPI give you to get it repaired?

Value is all relative.

8 years isn't a long time. I've been porting heads longer than that, and rebuilding engines more than three times that long. 20k miles "with no problems" is scraps. OEMs test more than 10 times that for durability alone.

Obviously TRD knows something about the tC that you don't. There is a reason they decided to limit maximum torque, and there's no reason they couldn't have made the engine a torque monster. Loading from the sc is no big deal, calling is a strain is a big stretch. Probably as big a stretch as running NA cams with turbo that are not fixed timing, when you don't really know everything Toyco did with their VVTi to provide the solution they did.

You chose a different route. Great. You don't care about warranty. Great. You plan on taking personal responsibility for anything that goes wrong. Also great. Just don't expect Toyota to fix this guy's problems. He didn't say he want to do what you did. His first question is: if I keep the boost low, will the engine be reliable? That's not the same thing as "how much power can I make with this configuration?"

i understand his question, i was jsut showing a point that you can run more than he wants to and be fine. and thw whole warranty thing, ill believe that when i see one get replaced. toyota will try their hardest to screw you. trust me, they already did with my tranny after only 5K miles and my syncros started going out ( many others had this problem) they didnt even want to fix it and tried to tell me that nothing was wrong with them. it wasnt even boosted at that time... you best believe your ass there going to give someone a hard time and try to find ANY possible way that they were racing their motor when it blew. im jsut speaking from experience. i had to fix my own syncros (i then took them into the toyota dealership who pretty much called me a liar and put them on the service mgrs. desk and told him he had new paperweights. he asked what they were from, and i told him "from the TC thay you said nothing was wrong with the syncros" boy did i get a apology. but the bottom line is, is that dealerships cover their ass to the max. so get prepared for a ass reaming if you try to take it in. but lets not get anymore off topic. do what you want bro. if you need any tech help, il be more than willing to explain some things to you. granted i dont have as much time on motors as lo bux does, but i DO have knowledge and im not a newbie when it comes to cars.

i do understand there are people who cant tune cars like i can, i understand i cant tune cars as well as others, but the point is, is that it cost money to make reliable power, its not cheap. and if you cant tune a car yourself well, and you dont have the money to get someone to do it well, then you dont need to be boosting anything.
