I just bought one i idont want to get rip off from some shops around here. i know how everything works and probably i could do it but i know i will phuck up in some point so i want some advice here.how much would it be the whole set up on the car.thank you

never had to let a shop install anything for me yet, but I'm guessing around 500 bucks

It should be around $300-500 the for a basic DRAG turbo kit install. I usually charge about $300-450 depending on the car. Like the Prelude, its a little more difficult because of the less room than a Civic.
I sell the DRAG kits starting at $2850 but with install, I'll do it at a pretty reasonable price if they get the kit from me. Be careful of hidden charges too. I usually include the welding of the oil pan with the install price, others charge extra for that. Ask them for any other charges such as oil, gaskets, etc. so you are prepared for the final price.
Hope that helped out.
Also, price depends if you are adding turbo timer, or custom intercooler(bigger than the regular kit), etc.

we usually charge around $500 to install a turbo, anymore than that and I would look somewhere else.....
