Ok so I have a 13b in my 79 rx7... And I'd like to up the hp.. Been thinking 20b. But I'm not sure what all I can use from the 13b like wireing and such. So cld some one give me the details of what I would need And prices.. Ty

 

You will need a good rotary engine shop to perform the work. None of your engine wiring will work with the 20B, so the shop will need to install and tune a standalone EMS. If the guys at the shop are friends of yours and are willing to do the work for free, then plan on $10-20K for parts, depending on the level of your build. Otherwise, the going price for engine rebuilding, installation, tuning, rebuilt or replaced turbo, and appropriate suspension and drivetrain upgrades is about $35K.

See the 20B FAQ for more info.

 

Bam!

So about 2 to 3 times the cost of a full turbo conversion.

 

Or I can jet take the money and buy one with a 20b already in it for less.....

 

That's true, and quite honestly, one of the smartest things you can do if you're more interested in driving the car than building it.

 

I totally agree.

 

Like everyone else said, that's the smart move.
