Long story short, rescued my baby from an abusive relationship. Engine is basically done and with gas going up im not 100% sure that I want to rebuild the rotary. I figured I would drop the chevy small block in her but im not completely sure on what all I need. This is my first conversion ever.

http://http://www.grannysspeedshop.com/

This is the site that Im looking at getting the kit from. It doesnt give you direct links so basically from the home page:
Click the red FC
Then click the Chevy small block

My question is which one of these kits will i need at the very least with only having the actually chevy engine? I was looking at getting the basic kit plus or the basic kit w/ drive shaft and w/headers but again I'm not sure.

Secondly, I have read that the TII tranny will work with the engine. Any clue?? or can i just use that N/a tranny with a upgraded cluth?

Open to all comments and suggestions

Number one this is the totally wrong forum for this. Just prepare to have the flame suit on. Most rotor heads will get pissed you are doing this and trying to put an SBC in your FC.

Go to www.norotors.com and you will have all the info there that you need.

No you cannot use your rotary tranny with the v8 swap, there is no way in hell it would hold, especially a non turbo tranny.

Its just one of the options available. I really want to covert it to a single turbo but I#m in the process of adding up the total cost for the 13bt conversion and the chevy/muscle conversion.

I have a 91 N/A by the way.

Edit-
The main reason I dont really want to go american is because I know my rx wont handle the same

Number one this is the right forum for this (OTHER engine conversions) however you will find next to zero help here. Follow the link above and you will find ample info.

Last and most important. You WILL NOT ruin your cars handling with a V8 swap

Go 13BT, easier, cleaner, better looking, better sounding, better feeling.

And your soul shall stay pure! ^_-

What are your HP goals for your new setup? and how do you plan to use the car? An aftermarket single turbo rotary is a blast to drive without a doubt! The sound of the turbo, BOV, wastegate, and unique rotary exhaust are music to my ears. But if you wanna try something different and go with the chevy v8 then by all means go for it. TQ is always on tap, no complicated turbo/aux inj system to monitor,and better gas mileage to boot. There is nothing wrong with taking advice from others but don't let thier personal opinions dictate your desicion. BTW I love me the sound of some cam'd V8

In all honesty project I have no HP goals. I always wanted to do a swap on my 89 but the engine was still in good condition. My main goal is to get my 91 up and running. I just figured since I was replacing the engine I might as well upgrade.

Its main usage would be highway driving and some drift or precision driving on the track every now and then.
I used to think that dropping muscle in the rx was blasphemy before I started school. For some reason I became more open minded to the idea as I had to spend more time doing networking protocols and less time working on the rx or play driving.
The thing about the muscle coversion that appeals to me is increased raw power without the need for turbos and better oil/gas consumption. I thought that the weight diff between the 13b and the muscle engine would effect my handling but you said its not something to worry about.

Untimately you will need all of those parts but it may be cheaper to buysome of them used or not in a kit. Follow the above link (which will probably be deleted soon) and introduce yourself. The people there know a lot more about a small block/FC than I do.

Did one of these swaps myself in the summer of '07 on an '86. In hindsight it was straightforward. There's a lot of room in there. Just don't cut your wires. *hassle later!*

Here's what we bought from Granny's: converter flange to bolt chevy driveshaft to RX7 rear end. $35. Other than that we made the rest with channel iron and a hammer.

If you want it clean, buy the kit. If you want it cheap and know how to weld, fab up your own braces and stuff. We got an old Firebird drive shaft and had it cut down to size and the flange mounted for >$100. We spent about $800 total including engine, trans, radiator, shifter, lines, whatever else.

I could tell you more about our rigged car if you want, but follow the advice and start searching the forums. I learned by looking on v8rx7forums.com back then and it was invaluable.

AND MAN IT WAS FUN!! =)

this may be true but my first thought was the good old chevy salute.

as far as the weight change going from a TII or Stock twin 13b to a all-aluminum LS engine is minor and can be off set easy, There is a larger change in weight after spending $40 bucks at the gas pump.

It's really not that big an issue.

Neither your NA tranny nor diff will be suitable.
The T2 diff will work fine.

Both Granny's and Hinson make OK, workmanlike mounting kits.
Justin Samberg makes the real nice stuff (mostly for FDs but I understand there is a FC kit in development).
I wouldn't use either Grannys or Hinsons headers or driveshafts- there are better/cheaper alternatives.
I wouldn't use either of their cooling systems either, for the same reason.

A FC swap is a piece 'o cake compared to the FD swap...more room in the bay, less electrical to deal with and no powerplant frame to contend with.
Of course, the FC will never have the suspension that the FD does but in most other respects it's a better platform for a swap and makes for a very interesting ride when complete.

any chevy engine will work,id suggest the ls1 kit,you can get the lm7,lq9,ls1,ls2,ls7 (etc) but the problem with those engines is the transmissions(t-6 6 speed) are stuid expensive,and the older GM enignes, are cheap and easy,but the trans can only hold up to like 300 ft,lbs,and anywyas,oce you pass 200 LBS you'll blow up your rear end unless your running a t2 diff(S4),but ya,if your looking to the basic kit Plus,and a AC relocation kit,LMK, havea brand new one,never used, for sale(went KA powered) any firther information can spit it out off the top of my head

Prophet3976

Eh, its seemed like it wasnt worth the hassle. I found someone who wants to buy the rx shell. I decided to just get a C4 and come back to rotary when the rx9 drops >_>
