just got my LS1 for my subaru WRX
Should be fun, those are stock 98 LS1 heads though, same ones as my swapped engine has.
Do you have a goal date to have it moving under it's own power? (done is never the right word here, what project car is ever completed?

The standard R-160 diff in a WRX is not at all strong ( I believe sone Nissan/Datsuns also use an R-160, which refers to crownwheel diamater in mm )
The latest STI uses an R-180 diff, which is stronger, as are its driveshafts etc.
an R-180 rear end will bolt straight in, but buy complete with shafts and hubs etc.
Tallest rear end ratio is a UK/Euro/US spec STI which has a 3.54 rear end.
Jap specs will have a 3.9, as they use a different transfer box.

not ls6 aka z06 heads
it looks like you have the zo6 intake manafold. as there is no EGR present.
plus you have a 98 style water pump.
since your adding boost id try to get some 6.0L heads bigger CC will alow for more boost.
All of this just to beat a turbo mustang

But perhaps that is not even an LS6 intake and just a plain jane 97-98 Corvette intake. The C5's had a EGR less LS1 intake.
Personally with the 97-98 heads and that intake, I think you got just a plain jane 97-98 LS! out of a vette. Not a Z06 motor. Pull the heads off and take a few pics of thise for us.

LOL, dont we all. you should not start a project like this if you do not have the $$$ to finish it. I would say the chance of you getting a large sponsor is 0%. what do they have to gian by giving you $$$$? you have a one off car that they will not build conversion parts for. the car manufacture sure wont give you $$$ (they would kick you in the nuts though). just slow down a little and finish the project a little slower. it will be an awesome car!!

if you need help with the turbo piping let me know.
Remember to correct for bumpsteer. Moving that rack will add another component to the conversion equation.
An R230 300zxtt/Q45 diff is nearly a 9" ring gear and is very very stout. Putting a solid rear end out back....
. Why not keep it IRS and put some upgraded 300M axles along with it? IRS cars can 60 foot awesome as well.
Maybe you should create a mid engine LS1 powered Brat with C5 transaxle instead. You could have 2 turbos mounted on a roll bar like the original KC Daylighters!
