if you want reliability, then go for superchargers.
if you power is all you care, go for turbos. you can drop an Aristo twin turbo engine in there. |

are you 2 serious... a turbo is proven more reliable... ford has even said that there supercharged cars/trucks need a special tune-up after a certain amount of miles...
superchargers put stress on the engine... power is taken from the engine to tuen the pulley, resulting in stress.. a turbocharger uses exhaust gas and takes no power from the engine... turbochargers are very reliable kept under 7-9psi and properly cooled to keep for dentonation... |

But what is the chance of having a turbo boosting less than 10 psi? Even most stock turbo vehicles boosts higher than that. And most people does not know how to take care of a turbo. How often would you see people with turbo volvos and saabs that had installed turbo timers?or the owner sits in the car for a few minutes before shutting off the engine and leave the car? |

I would have to agree with the proper care statement, almost nobody that has a stock car with a turbo even knows the benefits of letting the vehicle run for a couple of minutes prior to shut off to properly cool the turbo/bearings. but again most stock vehicles run 10-12 psi and have lower compression ratios to account for the increased cylinder pressures. people that are adding turbos and blowing up their engines are not installing dished pistons with 8.0-9.0:1 compression ratios and properly adjusting timing and upgrading ignition components. if these are left out or not done with higher boost levels s/c or turbo the engine will fail! and again turbos and superchargers have pro's and cons pick which ever one is right for you by price and component quality! |

go with a supercharger for boost at lower rpms and turbo at higher rpms. IOM supercharger is more reliable, turbos have that dam turbo lag.

it is a known fact that superchargers (roots or centrefugal) cause excessive wear on motors. specifically the crankshaft bearings (due to being pully driven). any well maintained turbo motor can outlast a supercharged one. but the key phrase there is well maintained.

That were the prob. with a n/a engine. The're not made for turbos. Esp an IS300, with its high compression, and VVT-I cams. At least change the pistons and put forged pistons (low compression, flat top pistons). Oh yeah a turbo timer will help. Ive help out with a turbo on a 02 IS300. The owner has chewed up 2 head gaskets (hks). Booting over 11 psi. The IS300 isnt made to be turbo. If you are going to turbo the car, I suggest fuel upgrades, pressure reg, high flow fuel injectors, high flow fuel pump, etc. I suggest a S/C. Like the "AREA 51" S/C. To help with the wear on the crank, I suggest a lightweight pulley kit, all around. You'll get like 250 HP with the s/c. Plus you get that cool supercharger whine.!! Also you cant compare Ford engineering with Toyota engineering!!!!! Say what you want, but thats the sorry truth. Sorry for the continous Ranting. |
