You'll need to refresh the new minds of the forum as to what this celica dreamboat is headed toward. Hell, I've been here for three years and I still don't know exactly what you are doing to that car. And I even clicked your link in the sig!
Well started off as a small project, then snowballed into crazy

Then a lot of off/on again deal and life/family issues.
So big part is the IS350 engine sitting in the engine bay. Eventually the Celica will be a time attack car. It's part of the reason I went with the 2GR-FSE, I wanted stock OEM power, good weight distribution, N/A power, efficient and I wanted to work with Toyota's latest stuff.
Still a long ways to go, but it's slowly coming together.
Here's a list of things that have been done to it so far.
To clear the larger wheels (was maxed at 245 tread width, going for 275 for all four corners) And to be able to run the same offset wheels front and back I widened the front suspension and modified the hubs to take SW20 rear struts. It also allowed me to fix the major camber I had up front and now just have camber change on turn in.

Grabbed MKII LSD with 4.30 gear andputting the weir kit with stock spring as I was told the Weir springs are near full lock most of the time.

To fill up the fender flares in the back a Previa axle takes the place of the MKI supra axle. Larger vented disc brakes, still an F-Code diff, but all the bearings are larger than the one that were on the MKI axle.

I'm trying to lighten the front end as much as possible, so I replaced the bumper support with a Toyota Avalon aluminum support.

I'm also making fixed headlights, but I wanted it to look as if it was an option in the 80's. So I'm doing a grill blend. Still got a ways to go to make it look extremely clean, but it's starting to shape up nicely.

I have an LED array that will put out the same lumens as stock, but only draw 15w per headlamp. Still working on the way the light is illuminating so that I don't end up blinding people, but I imagine shining through the grill it'll be ok.
Lots more to list.
