What i,m really interested in is the rear suspension set up.I plan on using a Ford 9" with ladderbars trying to utilize as much of the stock floor pan as possible although connecting the subframes. Any info would be a big help in getting this project started.

If you're wondering about what to do in the rear I suggest finding a good toyota forum. There are some guys putting out serious HP numbers with the V6 turbo supra motors, find out what they are doing with their rear ends. I'm sure they've got a system and I doubt it involves a ford rear...

You may be doing some major fab back there... -Bill Seduce the attractive, and charm the rest. ****** 489 C.I.D., roller cam, aftermarket heads, tunnel ram, stock '54 Dodge rear axle assembly: which of these doesn't belong?

You will be ok length wise in the engine comp but it may not be wide enough, In a celica I had the width between the struts was about 1/2" narrower than a 440 with stock early B manifolds.

I really don't understand removing an engine VERY capable of producing over 700 reliable horsepower on the stock bottom end.There are many transmission options as well.The stock IRS center section is very beefy and will hold up to an automatic build but you might want to step up to a Dana 60 center section that I have seen in some Toyota builds.
