Should i do a complete t2 swap or should a just mount up the turbo and get all the wiring and such done? or should i mount the turbo then do a t2 swap this summer?
thanks let me know some ways of doing one of them

 

im pretty sure on a rotary u cant just swap a turbo onto a regular na engine without having bad consequences. id get a t2 swap.

 

^^ Beg to differ. Makes great power. Made more power then regular t2's. But I'd stick with rtek 1.7 and safc. You'll get by with plenty of power.

T2 ecu, pressure sensor, afm, use your n/a harness, turbo/manifold, down pipe.

If you have a s4, everything is cheap. If you have a s5, good luck. But it's straight forward and very easy. Just remember timing is key role in high compression turbo.

 

I agree, but I have to add if you can afford rtek 2.1 it would make a big difference and increase your power potential with the car.

 

The easiest/cheapest route is going to be a whole drive train swap. You'll want a TII engine, trans, driveshaft, rear diff, half shafts, ecu.

Make sure to get the same series swap as your car (S4 = 86-88) (S5 = 89-91), this will make the swap much easier as the you will not need to replace the dash wiring harness.

It only takes about 40 hrs. of labor for a first time person to do it.

 

First, you should start by reading the FAQ:

Can I swap a Turbo engine/Jspec engine/13BT/etc into my Non Turbo?
Yes, check these links:

What Turbo kits can I add onto my non turbo RX-7?
There are no longer kits formally made at the time of this post, however there are companies from time to time that do make available non turbo to Turbo Kits. Because most of these companies stop building the kits, or go out of business in short time, it is impossible to keep active links for them.

Most people that turbo a non turbo make their own kits:
Using the stock TII turbo, exhaust manifold with spacer, NA intakes and NA ECU:

You'll then find that by far, the most straightforward way is to perform a TII swap. No fabrication, and it bolts right in.

Now, if you are the kind of person that enjoys a project, has a few fab tools, can weld and has some time, then maybe it is worthwhile to turbocharge the NA engine.

But since you ask, I suggest a TII swap.

 

Whats the rtek 1.7 and safc? and that seems like my option i have an s4 so i need to get the s4 turbo/manifold. the s4 t2 ecu s4 pressure sensor? and what downpipe?
thanks

 

Oh and another question this person up here hereis selling a s4 t2 motor but it doesnt have the turbos on it ? whats the difference between the 13b na and that 13b?

 

You need to do a lot more research before looking into a project like this.

N/A 13bs and turbo 13bs have some fundamental differences. While the housings are similar and can be swapped out, the irons are not. N/A FC 13bs are 6 ports whilst the turbo 13bs are 4 ports.

@TheAbsence
I know i defiantly Im knew to rotaries this rx7 is my first car so i started with them but Im most likely not swapping till summer time as the 13b t2 engine needs a rebuild which I'm alright with but its just the bare motor thats why i was wondering what's the difference with them

 

The RTek is a programmable stock ECU. Good for lightly modded cars with stock and hybrid turbos.

The S-AFC is a piggyback fuel controller that fools the ECU into delivering different amounts of fuel by messing with the AFM signal. Good for NAs, lightly modded stock turbo TIIs.

I suggest you buy a TOTALLY COMPLETE TII ENGINE and TRANSMISSION to make this easiest. Then decide what you want to do about management. If you want to stay stock, get a stock TII ECU, AFM, pressure sensor and fuel pump. If you intend to highly modify the engine, then perhaps think about a standalone.

It is easier to ask "what is the same between the NA and TII 13B?" because the list is short. Off the top of my head: rotor seals, eccentric shaft, oil pan, a few gaskets, a few sensors. They are completely different engines.

 

alright so i can buy the t2 engine and transmission its the bare motor though and needs a rebuild?
or should i just look around and try and find a complete engine with the turbo and tranny?
if i buy the engine and tranny from the kid itll be 550?

 

I suggest you buy the complete everything, otherwise you'll be hunting for manifolds and such. But $500 for a TII block and transmission is a reasonable price. I'd buy it. Just know full well that the engine might not be usable, especially if it is from "some kid".

 

Thanks for all the info and help Aaron
And i Know I guess ill take the chance and see what happens
