The shop has been busy with a lot of other cars that came in before mine, it's race season waddya expect??? But they've got the fuel rails, flanges for the manifold, tec3r, and other various things there...i'm thinking things will pick up late fall or early winter. I'll keep all updated

Ok...some insight and advice please.
The 20b motors sticks out further than the 13b and blocks where the front sway bar would be. From what I have read this will cause the car to oversteer drastically especially since it's rwd...correct? How will the car handle with more weight in the front and the missing a front sway bar?
The stiffer the sway bar less roll is experienced and stiffness is determined by how the sway is made: Soild or hallow, diameter size, shape so on and so forth...So the second question is: Do you use sway bars from a different vehicle and find a way to fit it by finding different mounting points OR do you custom make one?

TeamRx8, We are pushed back all the way to the firewall, the transmission at the same place as it would be in a stock 8.
Speedrx8er graciously offered to send some pics of how he flipped the sway bar. It'd be great if it really turns out to be that easy. However something like that I'd figure my guys would catch.
Some track racers sometime switch out their sway bars depending on the track. If I went the custom made route that'll mean making multiple ones? damn damn damn

the RX-8 front sway bar is just a straight piece of tube with two 90 degree arms. I guess he must mean something other than it actually being flipped since it is completely symmetrical regardless of how it's turned around

Sorry I wasn't clear. I removed the sway bar with the end links on. When it was flipped(driver side bolt to the passenger side and passenger side to the driver side) It will lower the sway bar enough to clear.

You should listen to Zero R. Sean is very good w/ these motors and knows turbos very well. His shop is A-spec Tuning. Again, he is very good.
You really need to open up the motor and rebuild it before starting it. I open up 10+ j-spec motors (13B) a year. Some are amazing in condition and some are suspect at best. I have seen the water seals grooves rust out on several ocassions from sitting. This leads to an immediate overheat problem. As well as ditching the 3 piece seals for 2 piece.
The FD trans is much stronger than the Rx8 trans, this is a fact. The rear end of the FD is stronger as well.
There are several other issues mentioned that have been covered.
I think you are going to find this project to take longer than expected due to problems arising down the road that you have failed to address in the beginning.
I have experience w/ one of these motors in a rx7. No its not a rx8 but the principles are identical.
There is a lot of info on rx7club.com. It would help you to read the 20B forum for a while over there as it will help you understand a lot of what the knowledgeable people are talking about.
Good luck and I wish you the best on this project.

Secret to20b / 3 Rotor in RX8 Rack Steering
Secret to 20b / 3 Rotor in RX8 rack Steering
I read in another Post,
(RX8Club I think)
that they found that Moving the Rack,
to the Front of the Crossmember,
solved the clearance problem,
and they observed that it looked like,
it was designed for future longer engine,
and the Push angle was actually better.
That is a better Solution than,
Now that you know the Solution get to it.
