20b Swap?

I've been looking at 20b's to put in my n/a but if I do do a swap, would it be the same as replacing parts like you would to do a n/a to turbo swap?

You probably don't have enough money, and to shorten it up, you'd need to change the same stuff as if you were doing a TII swap.

NA 20B has about the same power potential as a typical turbo 13B, so as already stated, the T2 trans and diff stuff need to swap in regardless.

There's plenty you can do with your N/A... As long as you've got the cash. The information is readily available.

There's plenty you can do with your N/A - as long as you have realistic expectations. Focus more on handling and road holding and not outright power.

Well I have short and long term goals at once. I already bought hubcentric wheel spacers, plan to buy a strut tower bar, new wider performance tires and wheels and adjustable coilovers but I cant lower my car than the stock height or my driveway will rip off the body kit.

It sounds to me like you want to build a "drift mad quick yo" show/drift car, so why don't you just buy a Turbo II? A used 20B engine sells for about $4,000-4,500, so if you were planning on spending that kind of money then you could easily buy a decent Turbo II car. The Turbo II would make a much better base to start with. Even better, save your money and buy a pre-built 20B RX-7 at 1/2 to 1/3 the cost of the build. While I like the NA cars a lot, in your case I think you are not being very efficient with your build unless your car has a lot of non-removable custom modifications already.

n/a to turbo a few grand. n/a to 20b 8 grand then keep adding for all the upgrades you're going to want like single turbo when it only runs 13s then upgraded suspension and radiator, brakes so drive it right and the list goes on and on.

I'm gonna go with a single turbo 20b in an FD when I get one in a couple years. maybe bp or pp.

Definitely want my FD to sound like this
