Default The 20B Rotary (2 liters of 3 rotor mayhem!)

Okay since my 13B has become wasted, I think I shoudl go for something off the wall - something be known for around here. I am considering in dropping a 20B rotary engine in my Turbo II. I've done a little research, but I think I'm lacking some things... I know I need the engine, the mounts, and probably the cosmo ecu, but what else should I take into consideration? I have come into some money, so I think $10,000 isn't too steep of a limit. If there are any rotary knowledgable people around here, give me some good input. Also the Turbo II currently has LSD, eibach pro springs.... what else should I add if I go through with this?

wont you need an entire fuel system?

and are you better off using a DEFI/PMS/motec?

ask Grey-GTC, shannon.. i dunno if he knows much about cosmos but hes a 2rotor genius

tri rotors take alot more then just the additional case. i think that you have to change alot of stuff. i can think of better ways to drop 10grand though.


pettit racing does them i know, may want to talk to them

Default Re: The 20B Rotary (2 liters of 3 rotor mayhem!)

With some research, I found out that it is a direct bolt-on to my tranny. I found three 20Bs for less than $3500 (that's with shipping). So, I know I'll have to push my radiator futher forward because it's like 7 inches longer and I'll need to get some custom mounts. I'll also need a frount mount intercooler. I also need the wiring harness from the cosmo and the cosmo ecu. So I'm looking at roughly $5000 already. This would make an awesome project if I could actually do this... and I am seriously thinking about doing it.
