A turbo 350 has only 3 gears. The 700R4 has 3 gears plus over drive and lock-up converter. And it is the same as a 400 turbo with overdrive.
There are 3 foreward gears and 1 reverse gear.
The typical turbo 350 has three speeds forward and one reverse.

between $700 to 1500 depending of if its turbo or non turbo
by putting your gears as manual
120-130 with exhaust smaller sprocket
If you have an automatic gearbox, 4. Plus two extra overdrive gears, in 3rd. and 4th. gears. The total will make 6 different gears. European Volvo 960 with 2.0 liter turbo engines have manual transmissions with 4 gears plus manual overdrive. The later S90 was also available with 5 gear manual (reverse was synchro!)
A 400 Turbo, 350 Turbo, and a 700-R4 (TH400, TH350, TH700) I recommend a 700-R4, all around best transmission, and lots better mps's compared to the others
Turbo Hydra-Matic 700.

Depends on size/options. But in general a new turbo for a 4cyl. around $500-700 for a stock T3 turbo/ super60, up to $1,500 gt35 with ball bearing/ported/billet wheel etc.. A v8 would need 2 of the ones above or one large turbo - around $700-1200 but go upto $2500+.
