Here are my concerns for you.
1) The Solara Unibody will struggle with a LS1 torque monster. At the very minimum, the front and rear subframes must be tied together. I would say that a full roll cage tied to the subframes and the frames together should be done. Heck, you could just go full tube chassis and sheetmetal floorboard.
2) Check your steering solutions. Doesn't the rack attach to the firewall right where your new transmission will want to go?
3) If you're going to hack up the floorboard for the transmission tunnel, you may as well add bellhousing shielding and crossmember bracing to support the transmission.
What were you planing for the rear end? How about the rear suspension? Solid rear axle versus independant.
My advice is to look for a wrecked car and work from that. Don't chop up a perfectly running vehicle since you will need it for your project anyway.
Have you gone off running and screaming yet? I think you should. I suspect you won't like all that is involved to get it done. I suspect it will cost more than you think. When it's all done, what do you have for the money? Was it worth it? Probably not.
BUMP, BUMP, BUMP....
Hell, GO FOR IT! (Brian, you are so right it hurts.... then again, the "race car builder buddy" IS in his late 30's.....
Goose, I'd hook you up with my '89 Supra at around 400whp, and with the switch to a Garret T04, injector swap, fuel pressure regulator, and minimal misc. parts, it'll put 500whp to the ground.... and the chassis/clutch/suspension/etc... are already all done. You would be THERE for less than 15k INCLUDING my car AND the labor.... (I think you will run every bit of 15-20k to do this project.... and it will take ALOT of time!!)
I got too many toys & projects laying around.... someone come take this stuff off my hands!!! (I could sell you JUST two 10lbs bottles of NOS for a "quick shits-n-giggles" on the 'lara in the meantime....?)
PS Reason I agree so strongly with PHREAK.... I had a Japanese "ZEN MASTER" senior advisor come over from Japan and work with me on a project this past couple months.... he used to be THE 280/300Z car test driver during the development for Nissan for YEARS.... I showed him my "modest" Solara mods, and he checked the engine bay, underbody, suspension, etc, etc.... and said: "much more power than mid-200's to 300 out of this, and you would have serious chassis/body flex issues.... not designed for such applications..." just as a comment when talking about the differences between my Supra and "modest" aspirations for the Solara....
BUT THEN AGAIN, DON'T LET US tell you SQUAT if you are set on pursuing the project.... just consider the voice of those who have already met the demons who live beyond the "point of diminishing return"....
Good Luck in your decision.... keep us posted.
