Question 13b intake help

so, first off i am building an offroad car.
i have a 13b i am putting in it.
NOW what i need help on is..
i dont have any intake on it. i have heard side draft doesnt work as well as downdraft for offroad applications. (is this true?)
does anyone recommend a set up? AND i want to run a turbo..
i dont have any knowledge on this and trying to search online isnt working well for me.
any help would be awesome!

13Bs were made from about 1974 until the current Renesis. It would help if you could tell us what type of 13B you have.

i was told it was an early model, gen1.
i been reading on here and some people say carb is not the way to go.
some say if its done right there is no problem.
its a 4port
also, i am running a vw pyramid transmission, ive heard you have to turn the trans upside down.
maybe the motor runs the opposite direction?
i dont really know where to get this info at haha.
i was trying to see if i could find some online before i go somewhere

I think you would be well suited using a side draft or down. I have both on my track cars and happy with either.....

Have you ever done a blow-through carb setup before? If not, and if you're comfortable with EFI, I highly recommend going with fuel injection instead. All carbs have trouble with fuel slosh to some extent or another, and tuning a blow-through 2-barrel carb is a pain. I don't know what kind of power you're aiming for, but the 2-barrels also have fuel delivery issues in turbo applications. I do not recommend a normal 4-barrel carb for an off-roader because they have severe fuel slosh problems on rotaries. A boost-prepped Nikki carb with a redrilled stock intake manifold might work okay. They're a bit restrictive, but if you're not aiming for maximum power, that doesn't matter so much.

bro there its a 8 injector throttle body for rotary engine look for it in google...... and also buy some good injectors you dont need to use 8 of them if u dont want too.... and you also gonna need a intake manifold.... and a fuel management computer... and that would make a perfect combination
