thats a pretty decent site I stumbled upon I've seen some discussions of V8's in FB's being insane overkill in power, but I dunno and if you feel like getting everywhere fast and probably sideways go do it lol I say if the 12A is still functional keep it till she blows, so its still an RX-7, most people go with LT1's and other vette motors, they seem to fit well or whatever, but if you decide to do it anyway, GL, and take many pictures along the way

Yeah a nice combo with the FD is the LS1 motor. I just love that rotary sound especially when it is a turbo rotary. Well if my FB was a 13B I would not think of this conversion. Just think it is cheaper to do a v-8 coversion than a 13B turbo conversion for my FB. The only thing that I hate about rotaries is that they are really exspensive. :thumbdow:

Well since I am so impatient the project is about to begin. I pick up the 700R4 tranny today and my buddy is going to do a fresh rebuild on it. Next month I am going to order the 350 small block from Summit. This project should hopefully be completed by next summer.

rx7's were not designed for straight line performance. pulling the rotary and throwing in an anchor takes from the designs of the car, therefore ruining the car. this makes it GAY.

Putting in an LT1 or LS1 will hardly hurt the handling. A lot of guys who have done the swap actually like the handling better with the Chevy.

The TII 13b weighs in around 400lbs, while the LS1 almost hits 500. So a 100lb difference in the front which can easily be counteracted. Battery moved to the rear, fiberglass hood, take out all unnecessary parts. You end up with a car that has much more potential and reliability. The car ends up only being about 30-40 lbs heavier in the nose. Not too shabby.

you also get a car that with enough weight reduction will lift the front tires lol

Here is a little more info about this swap. I got to ride in one yesterday with an LS1 in it and it is the shiznit setup for an FC. The RX-7's layout and structure is well suited to engine conversions. The rotary engine's eccentric shaft centerline is way up in the center of the rotary engine, dictating a much higher transmission location than that of a piston engine. The net result is that Mazda designed the RX-7 with a HUGE transmission tunnel, big enough to fit even the monster T-56 6 spd manual transmission which was used in the Viper and Corvette. The rotary engine's low torque output required Mazda to use a very heavy flywheel and a high rear gear ratio, a combination of factors that combined induce large amounts of stress on the RX-7's rear axles and hubs. Mazda planned accordingly, and designed plenty of strength into the RX-7's rear differential/axles/and hubs. Experience has shown that the stock NA RX-7 components are strong enough to withstand low 10sec 1/4mi passes, a feat that requires around 500hp. Now does this sound GAY?

No one prefers the weight dist of the V8, but the benefits in reliability, drivability, and not having a car that sounds like a chainsaw on crack greatily outweigh the weight distribution problem. PS, if anyone is intrested in a sweet sr20det powered fc let me know immediately

i've never weighed a complete 13b, but ive held most of the main components (rotors, housings, etc..), and im pretty sure that a complete 13b does not weigh 400 lbs. adding that much weight DOES throw off the balance of the car. i said nothing about drifting. im no armchair engineer, and i care nothing about what weight distribution is prefered for drifting. im speaking only of real racing, in which moving the weight forward in an rx7 is in no way beneficial.
