Since I have never run a 225, only a 170, I was thinking in terms of of that engine, sorry. You are correct, about the 25, and I am also correct, about the 170. But either turbo is pretty hard to find in a salvage yard.

PS: Why do you delete so many posts?

I like them both. The nitrous car, launches harder, but the turbo runs more mph, in the quarter. The nitrous makes a ton of low end torque, the turbo more in the mid to upper rpm. Also the Cuda weighs 3250, and the Valiant is about 2900 lbs. on the starting line.
A turbo can be "sized" to make bottom end torque, also, mine wasn't. Just look at the 60 foot times the Drake's Simca pulls.

where do you guys keep coming up with the turbo being more exspensive than nitrous?!?! i see nitrous kits for $500 min, and turbos for under that! &#@% nitrous man! i seen a guy put one turbo per cylinder on a v8, thats the route to go.

How about for a car that is a daily driver plus sees occasional dragstrip duty? With gas at $2.65 a gallon, what is the impact of a turbo on MPG?
I assume that the nitrous holds the advantage in this area.

Because a nitrous kit includes most of the parts you need to install it. Adapting a turbo to a slant six often requires a considerable amount of machine work. If you have welding equipment, a Sawzall, and a milling machine, you might be able to adapt a $50 junkyard turbo for just the cost of some scrap and welding wire. But if you have to pay a machine shop, the costs can go up. And this assumes you are going to try to use the stock carb, ignition, and fuel system.

I've spent around $2,000 on my turbo buildup so far, and it's not even finished yet. Over $1,000 of that is for fuel injection components - machine work on the manifold, injectors, a Megasquirt ECU, a $200 wideband oxygen sensor controller, and more. I could have done things more cheaply, but I want to cut as few corners as possible.

alright, well that makes sense. Then again i do recall hearing people spend even $4000 on turbo setups to.
