I wonder how much is Pettit Racing asking to do a 3 rotor conversion? coz I noticed there many 20B engine in Australia for reasonable price. What do you think guys? Any 20B Fd owners here?

Pettit charges $36k+ to do it..
You might be able to do it yourself for about 20-25k if you do all the work.
I've heard KD Rotary did one for over 25k, I'm not sure how much over as the owner said he lost count after 25k..
There's two ways of getting it in there. You can either move the firewall back and set the motor back to get it in there and then shorten the driveshaft, ppf, etc(the pfs way) or go with pettit's way(easier but not as good)..
You need a pettit front subframe/spindles which is 2k, ecu 1.5k+, intercooler 1k+, motor 4k, rebuild 4.5k+, clutch/flywheel 1k+, and then fuel system, exhaust, radiator, tuning, etc etc..
In short have money to burn and time to have your car down for a while or just have a little more money to burn and send it to pettit.

You can always wait for one to show up on http://www.thepartstrader.com and buy one for 2,400-5,000 and rebuild it, after that, take it a rotary specialist to do some fabricating but that would cost you anywhere between 16k-36k depending on who you do it with. I'm planning on looking for a guy that will fabricate a custom subframe for me to bolt my engine on and distribute the weight around. Another thing worth mentioning would be replacing the housings with lightweight aluminum housings at places like Racing Beat because you are putting in a bigger engine and if you want to keep your car light, you should pay the extra money.
