^agreed, but in the choices id say 13b

 

an LS1 would be fun, but it is becoming more and more difficult to actually find a 7 with a rotary still in it

 

If you want to go v8 without the cost of a ls1 id say go with a 1uzfe or a 3.5l rover v8 both are aluminum so it would save you the extra weight and they both also love the boost

 

IMO stick to Rotary bro... ive seen RX-7's smash on corvettes and camaros all day and they have a rotary under the hood..

 

I just bought my first rx7 and many people have suggested a LS swap... not for me, i want to learn/play with the rotary. in the end its really up to you.

 

ls1

 

13BT all day! haha

 

did Mazda make a like a 3.0 liter with a manual that could fit in nicely ?

 

Ls1 rx-7 is a unique sound too. Loud bark and a hard bite

 

rotary ftw

 

I think the Ls1 is a great engine, but the only thing that makes an rx7 to me is the fact is has a rotary. So that would kinda ruin it to me.

 

I built a ls1 fc convertable a few years ago and it was a great driving car. Nothing fancy , just a bone stock motor and 6-speed. I have nothing against the rotary it was just easier for me to get the results I wanted with the swap.

 

13BT for originality, LS1 for easy repair.

 

13bt!

 

And that's another reason why I havnt done anything about my car yet. Wish I had friends with rx7s lol

 

Cosmo

 

I'd say the rotary, it's the point of an rx-7, and its fun. Completely different... and 400HP on 1.3L? That's awesome!

 

ls1

 

Rotary, v8s are for wannabees

 

LS1 baby

 

Roartery ! But out of curiosity, how common is a Skyline motor ? I've seen them in some magazines, but can't find much about it.

 

Wankel all the way brotha

 

its an rx7 so u have to stick to the 13bt so much potental is there ls1 ull have the tq thats for sure but it competly depnds on wht its for but for me i will sitck to the haritage 13bt all day

 

exactly like K4 said, we r rx7 owners we keep and love rotary engine!!!!

 

I love my car but its cheaper to build a Ls than it is to actually build a 13b parts are Easier to come by also sorry rotory guys at heart no offense.
