why do you want to change your compression? what boost numbers are you looking for?

my goal is 8 psi.My engine is on the higher miles side 127,000 i turned it to 7 psi and blow the boot off the bottom of the turbo ( its because the I.C. piping is straight 90 degree angle but the turbo inlet is about 45 degree i cant get a good hold so i order a 45 degree silicone elbow and 2nd day air it should have it monday.When i dyno ran my car before the turbo results: 98.7 horse 128.7 torque after boost (5.5) i gained 35.5 torque and 32.6 horse not bad for that little boost >> you can diffently tell boost you gotta try it!

I Cant wait until i get my setup all done.. I plan on running 8psi >>

a turboed st = 160 hp
how much hp would a turboed gt be have.

I had never modefied the compression ratio and kept it high and ran 7psi boost on it sometimes. I didnt have any help and went on it by myself. My oil pressure was too high also. Intercooler is a must, i went cheap and didnt put one on. My setup would be pretty good for an intercooler because the piping would stay away from the engine and exhaust manifold. Sadly i have run out of money and the project is dead. I have taken it off of the car to spare the engines life.

how much skills and money for this kind of project

If you want to get the project done without half a$$ing it then you will need to know alot about how a turbo works. Or at least get someone that is working on your car that knows what they are doing. The cheapest way to go is to learn yourself and install the turbo yourself and piece together a kit, but if you dont do it right then you will face the consequences. If you have somebody else do it for you then its gonna cost a lot more and they may not care about how your car is gonna be down the line. I spent 2000 on my turbo but i missed a bunch of things like preparing my engine for the pressure. I should have done more research and had more things done. If i did it correctly, then i would have spent around 3500 but i ran out of money. unless your planning on showing the car, a lot of that money is going to go down the drain and youll never see it again, its an expensive hobby and thats what the people pay for cuz its something they enjoy.

i got a bigger mid pipe between the D.P the before the cat 2.5 and know the turbo spools hella quick now before it was 1 sec or 2 now its right away >>

here is a stupid question:

i heard that i need a 2 bar map for my turbo setup. what is a 2 bar map? is it a special manifold air pressure sensor? where can i get one? >>

what is the purpose of it?
