A turbo typically will not cause anything to break on the engine, rather the 1400 degree heat will super cook the engine bay. All the hoses and belts will need to be repaced every 25-50 k miles. The engine oil will be severly effected, meaning you have to run much better quality oil, and you need to change it more often.
When you shut down the engine, oil flow stops to the turbo bearings. The 1400 degree heat is still there. The oil burns and over time it will "coke" the housing and the bearing will go bye bye.
At 15 psi, you are almost doubling your volumetric efficiency of the engine. A 200 hp engine will develop about 375 hp at 6500 RPM. Go above 15 psi and your head gaskets, piston surface, valves, rings and everything will deteriorate. You can expect fairly expensive tear down and rebuilds every 100-150k miles. Many times it is cheaper to buy new turbos than fix the old ones.
A turbo is not an engine for a 19 year old on a limited budget. A twin turbo is not an engine for someone without access to dyno time, with extra money for tuning the engine for maximum power.
Really. You are not going to beat on rice rockets just because of the turbo. You beat up on competitors by having more off line torque. A 302 with decent home ported heads, cam, intake, and gears can easily run mid twelve to mid thirteen second quarters. Most rice rockets run 15.25 to 15.75 second ets. So you will have street and strip dominance without high expense.
If you want a good turbo car, look for a buick grand national. They could turn 12.1 quarter mile times with only mild modifications. Just remember you will be paying for rebuilding the turbo and the engine on a more frequent basis.
I really hate tubos on street cars. They are designed for racing at very high rpms. This is not a cheap way to go.
But good luck, and I wish you well. Keep your dollars totalled up. When you go past 1500 dollars, realize a 5 speed 302 would now be running 12.50's. Where are you now?????
