Re: Old School Meets New - Supercharged LSA into Grand Natio
Got the motor up onto the engine stand, and started in on the initial mods, which are the ones that will be pretty invisible and not affect passing CA smog.
Pulled the supercharger unit, which of course is not showing the lid here. This is easy as everything on top comes off with it - injectors, rail, sensors, etc. You just remove the cover then 12 bolt inside then lift it off. They even cast in a place for your hand to grab!
Cleaned out all the head bolt holes (they used something darn near stud & bearing mount for the head bolts - tough to remove and clean) and studded up with ARP:
The heads went off to West Coast Cylinder Heads for CNC porting, dual springs and titanium retainers. I also went to Inconel exhaust valves in case I ever put the Whipple 3.4 head unit on this motor (would probably need a cowl hood). The ARP head studs are stronger than stock and reusable.
Swapped on the MAST oil pan & pickup, which is the cleanest fit (and install - ever hit the bottom of your pan on the crossmember
):
I am accumulating the parts I will put in after the smog: Brian Tooley Stage II cam (from Comp Cams), Dirty Dingo motor mounts, ZL1 supercharger cover, overdrive pulleys, bigger injectors for E85, flex fuel setup to handle anything from straight pump 91 to good E85, and any blend between.
The Racetronix dual in-tank pump is on the way. I am hooking up a Hobbs switch set at 4psi to turn on the 2nd pump. This pump will handle anything I can throw at it. I will plumb the fuel system with -8 Teflon hose with a -6 return.
My target is 630-650rwhp, which is VERY doable on E85. On pump 91 it will be around 580rwhp. But there's lots of E85 around here now 8)
10 years ago who would have thought this possible in California? The smog Nazis are spinning in their graves!
The only sticker I actually want on the car.
Two weeks for the head porting. Time to pull the turbo motor and clean the engine compartment, unh.

Re: Old School Meets New - Supercharged LSA into Grand Natio
Got the old GN motor out last night:
~28 years of grunge built up on a motor/chassis combo that's 50% metric, 50% standard and 10% random "other" bolt sizes & thread pitches from around the world.
Now I can get in there (literally - you know what I'm talking about) to clean, remove bits I don't need and start sorting out the wiring that I will need after the motor swap, like AC/Heat controls, Starter/charging, etc.
The heads are on their way back from WCCH, probably will arrive tomorrow, so after that I can get the LSA back together enough to mark up the blower for some porting and head matching that I'll do next weekend. I may do some testfitting of the motor before that so I'll know if I have any issues like having to relocate the #8 and or #7 coils, or any mods to the AC heat shield.

Test-fitting the modified front accessory dressout - this is a mix of LSA and LS7 parts, LSA on the left of the picture and the ALT & PS on the right is from an LS7. This gets the ALT & PS up higher to clear the G-Body steering box. I love getting a big box of OEM parts and watching it come together.
This also shows the ZL1 supercharger lid, which has the IC lines in the front (should be better for my install) and is reported to be worth about 20HP over the shorter LSA cover:
I still need to use a pulley installer to put on the PS pulley, then I can fit the belts. So far, all the parts have shown up correctly, have fit, and look like the pulleys are all aligned correctly. Fingers crossed!
WCCH did a nice job on the CNC porting of the heads:
Boatloads of work ahead. :shock:
