Which turbo should i get for my scion tc?

the ZPIracing scion tc turbo kit-stage 0 or the GReddy scion tc turbo kit? both gives the car roughly around 100 hp but the ZPI only gives 6 psi and the GReddy gives 8.5 psi.

    Turbo kits with low boost and proper tuning will not blow your engine. 6psi is fine that is why many turbo-charged cars/trucks come de-tuned, meaning that the factory had low boost for increased reliability. So, if you buy a factory turboed car you can usually up the boost and for $20- $300 have 30-50hp increases. That doesn't mean that the engine cannot handle higher boost, they can and do, and aftermarket improves the ECU to accomodate fuel/air curves.

    However, your vehicle does not have stronger stock internal parts so keep the boost low and make sure to have a performance shop tune it if you don't buy the all-inclusive kit.

    One guy responded to you and claims to be a mechanic and lists a Z-28, 350Z on his resume. I assume he likes big engine cars, he's just scared that your little turboed Toyota will dust him in a race. The people that love big engines are always the ones to complain that small engines are not good. Tell him to go pay the high gas while the WRX, EVO, NEON, Mazda Speed 6, VW 2.0T (properly tuned), Golf R32 perform as well as his car for less money and less gas.

    Then he says that no aftermarket is as good as the manufacturer can make... Hmm... great manufacturers such as Ford that didn't adress the Pinto gas-tank problem? GM's quad 4 engines that had headgasket failures, the after market responed with a superior Multi-layer-gasket, but it was cheaper for GM to build a bigger engine instead of a more sophisticated engine.

    Example... Mitsubishi eclipse turbos 1st generation had engine "crank-walk" problems. Mitsubishi didn't want to recall the problem but luckily after-market machine shops stepped in with solutions. Saab has so much faith in their turbos that they now don't even advertise the car as a turbo even though it has a turbo, they warranty it just the same.

    The M series BMW has turned to turbos instead of building some giant v8 motor which would have cost millions more to produce than a simple turbo. Also, all modern diesels that I know of are turbo-charged and the tractor trailers are EXTREMELY reliable.

    The TC is a great car, we have had one in the family for about a year now. take it from someone that has spent a fortune on go fast parts for cars over the years, save your money! If you want a faster car save your money and buy a different car when you can. Its never as good as what the factory can make. The engine will lose its driveability, it will either lag at low speeds or surge at high speeds.

    After reading E E reply I thought I would add this. Yes factories do build turbo cars, but they typically have a lower compression ratio than non turbo engines. And they are not aftermarket designs, why else would they have factory warranties. If you want to see how the factory feels about aftermarket kits, just ask the dealer if a turbo kit would void the warranty. I don't care if your car is faster than mine, I don't race. You asked for opinions and thats what you got. Yes, many diesels are turboed or blown, this is as much for emissions as performance. And the more horsepower you get from an engine, the shorter its lifespan. A 350 horse Cummins 903 marine diesel from the 70's or 80's weighed in at about 4500 lbs and would go about 5000 hours between rebuilds. A 350 horse Cummins 6BTA marine diesel weighs in at about 1600 lbs but has about 1500 hrs between rebuilds. You can see by the engine weights that diesels are built very heavily to withstand the stress of putting out big power. If you really want to spend that money on your engine go to the Scion dealer and check out the TRD supercharger kit. At least it is matched to your car with the factories blessings.

    The TRD supercharger would be a better choice IMO. It comes with a warranty, there is no turbo lag or worries about lubrication since it doesn't use engine oil like a turbo. It doesn't get hot and it's easier to install than a turbocharger.

    if you can roughly get the same power from the 6 psi turbo i'd go that route.if it's still stock you don't want to run too much boost through it and blow the head.if the motor is modified i'd go more boost if you want that.

    I say get the GReddy turbo kit i think that one should give you more Torque along with the 100 h.p. and don`t forget the inter-cooler as well!

    don't you think you should worry about other things rather than turning your econo box into a fake ferrari?
