what do you guys think of a 1st gen that is about 2000 pounds with a 3 rotar?

 

I'd say a two rotor with nitrous would be beat it for a lot less $$$ and corner better due to lower engine mass....

 

Happy Birthday on the 28th.

What age are you going to be?

Just out of curiosity.

 

What old? Already English good you are speaking, Alecks

 

a streetported 3rotor with hi comp rotors and a fuel inj setup would kick ***. you would be looking at like 300 hp with a huge load of torque.

That would kick ***, plus 3 rotors sound great.

 

Got five digit $$$$$?

kewl! my birfday is on the 28th as well also too!

 

I was going to do it, and I actually just sold the 20B that was going in my 85 GS. The motor is the least of your costs. Don't forget, rear end, trany, brakes, cooling, exhaust, motor mounts, ignition, computer etc. going from 100 or 130 hp to over 300 requires extensive modifications. But if I ever have the money I will do it. I heard that you can't beat the sound of a 3 rotor. The stock 20B TT from a cosmo will produce 300hp on it's own, mild upgrades can take it to 450 easily.

In short have at least $10,000 -$15000 canadian if you plan on doing all of the work yourself. If you have a shop do the work you could double or triple that amount.

 

4 digits

roll in roll out for £4500 - $7200

 

And worse, a 180 HP streetport 2 rotor 12A with a 150 shot of gas would beat it...

 

and you get to see the look of on their face when you tell them they've been beaten by a 12a

 

2000lb with a 3-rotor? Good luck trying!

Rotaries are much heavier than they appear. A 3-rotor conversion weighs much more than a boinger conversion (which is roughly the same weight as stock).

 

What's so unusual about that?

 

I got my *** handed to me today by a V8...

`,=o(

I need some mods.

 

I heard that the 3 rotor wasnt much heavier than a 13btt?! And that it took some lightening to get it back to stock weight?!?!?!?!

 

jimlab weighed his 3-rotor on the crate and it was something like 562lb. that's about 150-200lb heavier than a N/A 2-rotor.

 

ya but why would you want a rx7 with no turbo and the extra hp coming out of it will easily make up for the weight. il be 17 on the 28th

 

200 lbs! Holy crap! But I'm sure it's easy to over come that when it's logical to assume that you can get over 600hp from it...Senior Hitman?? 650hp...wants 800?!?!?!

 

At 562 lbs, I would join the V8 club first...Bruce Fulper has a 350 cid Pontiac engine cranking out 542 HP on the motor with 400+ ft. lbs of torque at 2500 rpm. If I'm going to have an anchor up there, I'd at least like it to have real guts, ie., TORQUE...plus that engine would ingest a 250 shot of nitrous all day long, so that puts the total at 792 HP on a daily driver motor that idles at 900 RPM. A rotary with 4 rotors won't do that...

 

there are a few pics here.

According to Peter Farrell, the difference between a 13B-rew and a 20B is about 100 lb. My car is 236 lb. heavier than a stock convertible, but that includes a lot of other stuff.

 

478 lb./ft. of torque with the stock turbos and no interior engine modification. Perfectly adequate for a daily driver.

Based on testing with my car, Peter Farrell has stated that 1000 hp is a realistic goal for a 20B (assumes engine has been modified like the 13B-rew in Peter's drag car, including a 100 shot of nitrous).

 

In summary, it's a great idea, if you have buckets of money and the time and patience for a little R & D.

A simpler, though heavier, route is to buy my car. See www.cris.com/~Asam/20B.html

 

George,

Your 20B FC 'Vert gets me going.

I love that you took the HEAVY Vert, and put real power down on it. I also live the fact that you took the "ho-hum" FC lines and put a Mariah kit on her.

I would LOVE to buy your car. But my wife would kill me.
One Cosmo Project at at time.

Maybe in the future I'll buy yours or do one on my own. *sigh*.

 

At what RPM?

And you have to figure, it's still turbocharged. (Yuck)

I think his Pontiac analogy was meant as an extreme example.... Pontiacs are some ungodly-heavy engines! Now, on the other hand, a SBF would fit nicely and doesn't have the weight penalty of a 20B. And if you wanted, there's plenty of room for a pair of turbos.

- PJ (happy to say that a N/A 12A is more than enough...)
