First how much boost can the stock 2nd generation 13b engine handle safely??

Second question how much can the stock twin turbo on the 2nd generation put out??

Third question what are the spec's of the stock 2nd generation rx7 twin turbo?? Things like with of tires, weight of car and how much HP and torqe

Forth question i think i have seen the size of the stock intercooler on the 2nd generation twin turbo rx7 and i think it looked small would a stock Chrysler Conquest intercooler be good because my dad has a conquest and the intercooler is big would it be good on the 2nd generation twin turbo rx7?? thats all later

2nd Gen RX-7's only have one turbo. It's called a "twin-scroll" turbo because the turbine housing has two seperate scrolls to improve performance.

Th eengine can handle a lot of boost but the turbo, fuel system and intercooler cannot. 10psi is about the limit without upgrading these items. You'll need a fuel cut defender to exceed the factory fuel cut at 8.6psi.

Do a search for specs, as this has been covered many times.

Any interccoler that's bigger will work better. Note that the intercooler's biggest problem is not its size (it flows quite well) but it's location, which causes it to be heatsoaked at low speed. A front-mounted IC is a good idea once you start getting serious.

Hope that helped.
