New here, awesome site. I currently have a discussion about a new tc or used evo.

While I decide on my vehicle I've already considered that the TC will require some forced induction. Being new to force induction, it seems only logical that something like the ZPI stage 0 will give you more than the TRD SC for the money.

Toyota's willingness to provide you a warranty with the TRD SC only assures me that this engine will hold 6 psi safely. Why not then go for more HP with the Turbo. Aside from the warranty, what other harmfull effects am I overlooking that could harm the engine with a 6psi turbo applicaton? 230 vs 200 for almost the same price and same psi just doest make sence to me. Please advice.

boost, and learn, its really what its all about, i have all kinds of motor work done and what not and working on a bunch of stuff, turbo goes in in the spring, were thinking the motor will go 100K-125k before stuff starts to go on it, thats with routine turbo maintaince and such

adding forced induction requires more money ...just remember that

Put it this way, a kit that makes more power is going to put more wear and tear on your engine. Forced Induction adds more heat, which is more friction, which is faster breakdown. With that being said, R & D is important when developing a kit. The more R & D, the longer the life of the car, and the more power per dollar. It is really up to the consumer to decide who makes the most reliable kit, while at the same time considering how much you are shortening the lifespan of the engine, and considering how much power your adding.

The turbokit at 6psi most likely isnt going to harm your engine until around 90k-100k miles, but once you hit the triple digit number becareful, and make sure you keep up on maintenance.

MAINTENANCE IS KEY

since turbos ask a lot more from your car, keeping up on the maintenance a little more often than normal would be a good idea.

Good Luck!

I am looking at getting a ZPI Stage 0 in the next few months. The supercharger never even crossed my mind. I would go turbo long before supercharger. Even though (typically) the supercharger has the on-demand power, a turbo will give you more power after it spools up. And as the others have said...I have learned that with an aftermarket turbo on a new car...maintenance is the most important part of keeping your car reliable.

actually, its the opposite.

the turbos designed for the tC are spooling up to max boost around 2.2k rpm, while the superchargers are making max boost at redline.

Interesting.

Can someone go more in detail about the maintenance on a turbo TC. Are you referring to more frequent oil changes, perhaps synthetic, or are there other precautions that can be taken?

are you running a m/t or a/t? thatll depend as well

Please advice.

the sc will keep the car under warranty. the turbo will void it. i don't know about HI but in CA the sc is the only one that we can legally add. turbonetics is submitting one to CARB but, in all honesty, it ain't gonna go through, imo.

really, both will outlast the warranty. and both will shorten the lifespan of the internals regardless of maintenance. the turbo has more potential power but to achieve it will require upgraded internals.

the money spent on r&d for the sc is ahead of r&d on the turbo kits merely because of toyota's deep pockets.

low boosted turbo'd motors (around 8 psi) will last as long as a sc'ed motor, however, the turbo will need to be replaced sooner than the sc (nothing personal, just fact).

power wise, there is a lot more room with a turbo but in CA, i currently can't add one legally.

Manual Tranny.

No emmissions here in Hawaii, but I might be getting stationed in San Diego. What are these engines going for $$$?
