That sounds fun sorta.

Your poor control arms are gonna be flopping around everywhere

What's the key to preventing that?

Turn the boost down.

Or just build the front end up

[Fecomatter]

Yea, I would do the lower rad support mod. It costs 25 bucks in steel, and ~10 bucks in welding wire. it is significantly more rigid than OEM.

A few of the guys have fitted BF A arms in and set up traction bars. Which lets you eliminate the sway bar.

You don't want to prevent it if you want traction. The Festiva suspension is designed to flex and isolate the chassis from TQ fluctuations, while still allowing the suspension to travel in a natural rearward arc as it absorbs surface irregularities. In short, the festiva front suspension is an engineering marvel. Replacing it with A style control arms is like putting leaf springs on your 2016 mustang. The Festiva front suspension is a design used by cars such as the Porsche 911. The sway bar is tuned to work with the weight of the car. If you make this more rigid, you'll have inconsistent traction.
The part of the chassis that holds the sway bar can use some help though. That was designed for about 100ft.lbs of TQ. 300 ft.lbs is pushing the envelope a bit.
I wish we could mount a couple video cameras to Sonic to measure the front wheel deflection when Mike launches. I'm very interested in measuring that with over 250ft.lbs to the ground. I'd love to build a better front end, but it's hard to improve this design. I'd like to built drag links that absorb the TQ load like the stock sway bar does, but that's easier said than done.

Yeah I don't get why people over complicate things. If it's not broke don't fix it.

Exactly!!

So Charlie, are you implying to cut out the stock front crossbeam and replace with DOM or rectangle tubing would be the most beneficial suspension upgrade for the extra tq being applied?

This is one thing i have added on my jeep tj frame for crawling that has seriously helped.

Going back to the tranny issue, has anyone looked at the BP to e153 (toyota gear box) adapter plate option? I'm a noob, so I'm sure it has been ruled out due to the size, but I just had to ask.

E153 will barely fit in a 323. It's not going to fit in festiva without cutting out pretty much all of the frame rails.

[Damkid]

^^yup pretty much

I've seen comparison pics between the G series and E153, the E153 is much much larger and the advantage that a 323 has is higher frame rails so the transmission can go underneath the frame, where as the festiva frame sits lower which will cause huge interference issues

[HondaHunter]

I figured that was the reason, so it sounds like a tube front end would be required in order for a e153 to be plausible. If that is the case you might as well stick an FE3 in there. Maybe one day 😎

^^not to mention custom axles

The guys who've done the E153 swap did it in the BG chassis 323's and they found an axle set that fits the BG chassis, not the BF chassis so most likely we would require custom axles for the E153 to work
