Yes, 7s' engine are designed as FMR (front mid engine rear wheel drive) this is why the car has close to 50/50 weight ratio, if you see 13b-rew the engine sits behind the wheels.
and technically speaking the correct way of installing the 20B-rew is to move the dash, so that your 7 will still maintain the weight raio of 50/50.

P.S tell you the truth this is what i heard.so if im wrong about the installation on the 20b correct me if im wrong thanks.

 

they kinda just plop it in there.only pfs moved it into the firewall.

 

You can easily pull 900 horse out of a 3 rotor with upgraded twins!



ease up on the crack pipe dude

 

Or you can get the modified sub frame from Pettit racing.

 

I could not find the old thread, can someone please post a link.

 

you dont have to move the dash in order to have a 50/50 ratio. i dont think anybody does that really. i think your thinking about the pfs car with the gear shifter located a little further back. thats the only movement back in the cabin. pettit makes a subframe that does throw the weight ratio off a little, but you can easily change that ratio by the movement of other components that dont have any business in the engine bay. haha.

Yeah I've never seen the actual dash moved in 3 rotor installations. On the PFS car they move the shifter back because they are moving the firewall back and then they moving the motor/transmission back and then you shorten the driveshaft and power plant frame. Perfect 50/50 isn't that important to me as long as it's close.

 

I don't think Jim's car will have ideal 50/50 weight distribution, so it will likely handle like crap

just kiddin, Jim

 

what are some of those components?
