type 4 turbo guys-, what turbo did you pick and why- Options

Alot of turbo talk lately. Just curious, for those who have been there/done that, what turbo did you pick, why, and if your project is on the road, how do you like it?

Yea Jake, nice HiJack- I was going to mention that... For the rest of us who either can't wait/can't afford/or just like to tinker around with our cars, looks like airsix, sammy, and bug man have BTDT. Anyone else? I'd like to know a little more, not so much about the engine mgmt used, but the hardware- what turbo, what A/R it has in the turbine and compressor sides, compressor maps, blow off valves, wastegates used, how soon do you get full boost, intercooling used, or not. I'd be more interested in massive torque than 25psi and lots of top end- Like those cones, and something more auto cross oriented than 1320 oriented is my quest. I was thinking water injection, as I used that on a ford focus I turbo'd, but in cruzing ebay, the subaru wrx/sti top mount intercoolers look good, with one inlet and 2 outlets, perfect to go along with my dual throttle bodies now on the car.

without knowing all of your engine specs, driving needs and a bunch of other stuff...it's too difficult to give you all the answers.....

I recommend going to amazon.com and buying one or more of the following:

Turbochargers by Hugh MacInnes
Maximum Boost by Corky Bell
Turbomania by Bob Tomlinson

the last 2 are kinda old, but still good reading....it'll give you a good head start...

with many things, it's all how it's put together and used...for one person a turbo from a Ford T-bird might be too small for one persons needs and setup yet too big for yours....there is no one perfect setup, especially if trying to do it on the cheap...

in a nutshell in my personal opinion (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

intercooler yes (air to air)
the single turbo I am using is from a Dodge Stealth twin turbo (each rated to flow to 164hp under ideal conditions)
if you stick with a used turbo from a popular car, all the specs can be found on the internet

normally, the smaller the turbo, the quicker the response for low end torque....if you compete with your car, before you jump into adding a turbocharger, make sure you read the rules, the addition of a turbo to a car not factory equipped can cause you to find no place to play or classed with mega-dollar cars that you have no chance of ever beating....
