Hi Joe
lots of room to use stock cast headers or aftermarket tube headers. The SS hooker headers I purchased is for another LS3 twin turbo build (sand car). I put them on the LS3 motor for the 928 and installed. Had room to spare in the engine compartment. I am on the fence if I am going to use them on the 928 build.
Thanks Lance,
I am glad to hear that. I am a long long way away from this, but am keeping my eyes out for pieces and parts awhile.
I wish you were closer, i'd love to see your car when it is finished...
My numbers are not really precise but stock 928 TT measures just under 4", the C6 (manual trans) is 5.3" and the C7 is 5.4+ due to a layer of heat shield like insulation. What diameter is the C5 TT?
Joe,
Jim at Zero Gravity Performance (facebook) has a "translator module" to go from the Gen4 ECU to the Gen5 TCU. We have it connected in my big Jeep, but it is not ready to fire yet so I cannot tell you how well it will work. My ECU is GMPP LS3 and The TCU is stock 2016 Corvette for the 8L90.
Finally recived the super charger components, working with Andy at A&A Corvette locally. Andy is working with me on supplying parts to convert to the LS3 / 928 conversion. Looking at a real 550hp to 575hp at rear wheels ( not crank), on pump 91 octane with no mods to the motor ( daily driver) could easily go more but would not be reliable without replacing pistons, rods and crank, etc. . Just need to re-program the ECU, increase injectors to 60psi......we think stock fuel pump will be good, but will confirm on dyno.
So far the only thing I needed to do is cut off a few threaded posts on the water pump for clearance. I installed the fender and hood to confirm the the super charger cleared the hood, which it does, but will need to add heat shield as safety. So far everything bolts right in and clears, I will need to make custom aluminum intake and pre cooler pipiping. Also, I think I need custom size intercooler.......stay tuned.
Wow. That’s going to be a little rocket ship when you’re done with it! Very impressive! Not only your build skills but even more so how fast you’re getting everything put together...
Finished up rear seat delete. I will sound deaden everything after paint during assembly. Black carpet will cover everything and match rear cargo area..

You sir just made my evening!
I didn't think that it was impossible since the C7 corvettes came with the 6l80 before the 8l90 came out.

Nice! I'm actually going the other route and going with a modified motor to make the power and keeping it N/A
The guys at A&A are great to deal with from what i've heard on the corvette forum so i'm sure you're in great hands.
There's something to be said about not touching the motors internals from a factory build.
great build. Any way to add some sort of traction control too it all as you are using "GM" brains and harness etc.
My car breaks lose with little or no effort.?

Ewww! Sounds like a great way to ruin all the fun.
An experienced right foot is the best traction control out there.

Thanks for the kind words......things will slow down a bit with the holidays and my painter says he is booked through the end of the year, so timing is working out for me. There is a bit of plumbing to figure out with the super charger and want to make sure it is done right.
I am going to have to side with Fishah on the fun factor without the addition of traction control.
