V8 solstice project for my son.
« on: May 06, 2018, 08:12:49 PM »
Started this project a couple years ago and im almost about ready to start the engine.
Plan on doing a turbo 5.3 vortec steel block converted top end to an LS
Here is a list of current mods
Removed previous engine
Removed convertible top
removed everything inside the doors
shaved the door handles
shaved the flaps from the convertible
removed all interior
removed dash
Custom door panels
widebody on rear
started wide body on front
vented fenders for the front
20x10 rear wheels 20x9 front wheels
NGR race seats
this will be a fun garage queen kind of an new school cobra and i plan on having it finished in the next two years.

Nice custom fenders!

Shaved door handles probably a dangerous choice if you're planning on tracking it. (I imagine tech inspectors will nix the car over it.)

Thanks! its been in the garage for 2 years and slowly been working on the body been hitting it pretty hard for the last month i plan on having the body and interior done in the next few months then onward with the engine!
Welcome to the forum.  I am looking forward to seeing how those front fenders turn out.
Yeah once i added the wheels i got a better look at what im against . the 1 inch i pulled them didnt work looks like ill have to do something like i did in the rear. Another issue is the wheel at full turn rubs the bumper support but that is something i can fix as well.
Wow, nice project, keep us updated .... More info about the engine swap? :D
No engine yet i removed everything from the bay and it sits engine-less right now but that allows me more room to move. It will most likely be a 5.3 vortec with upgraded cam and LS intake etc. part of why i joined this for advice on where to get the mounts ETC.
Nice custom fenders!

Shaved door handles probably a dangerous choice if you're planning on tracking it. (I imagine tech inspectors will nix the car over it.)
Thanks yes i know the door handles will probably be a no go on the track but we will see it will have a roll cage and 5 point harness.... also no top on it so doesnt that make it easier to escape??? =)

Also I like the new placement of the driveshaft, not everyday you see a driveshaft going through trunk and close to upper part of the seats :D

If you can swing the upcharge for an aluminum LS, I think it'd be worth that in those cars. It's a pretty significant weight savings, and if you aren't running tons of boost you can more than get by with aluminum. (I can't imagine running tons of boost on a road corse, if you're thinking drag racing then disregard.)

Most lump all the gen III/IV engines under LS, LM7 included. FWIW LM7 heads flow very close to the LS1 heads, most consider them interchangeable. I'd just install larger valves in the LM7 heads, get them ported and polished and call it a day.

LM4's are pretty rare, depending on your area might be better off just looking for an LS1 if you want aluminum, or an L33 from a newer truck. Of course if you can find one for a good price go for it. Only downside I see to the L33 is cylinder deactivation, but if you're rebuilding the engine you can eliminate it pretty easily.

Why is that a downside?

Uneven cylinder wear, it compounds the existing oiling issues, fewer choices for cams, etc. The oiling concerns are reason enough to ditch it, never mind the fact that some folks I know said deactivating it doesn't impact their mileage by more than 1 mpg.

They make kits to "convert" the internals back to a "normal" LS. With the 5th gen Camaros I know most folks doing performance improvements to the automatic cars put converting the L99 into an LS3 towards the top of their lists.

Thank you that's great info. The last week i have been working to finally get the title in my name and it is as of today! long and many dmv trips story short, the guy i bought it from never transfered the title to himself he just signed the back . he is out of state he had to send me a power of attorney. Then i had to get someone out for a level 1 inspection , now i have the title and can put some money into it!
the year of the engine doesn't matter what would be the cheapest full build block to start with? 6.0L truck or car and it doesn't matter aluminum or iron and i am in AZ.
here are a couple shots of the finished door panels i did. The four bolts will be swapped out for a more finished look when i get something machined.

door handle is moved back quite a bit, that may be difficult to get to when in the car.  What do you plan to do for a roll cage?

you posted this and i said "shit! i haven't tried it from the inside getting out.." Its actually not back too far you just need to reach with your inside hand to open it doesnt bother me. Thanks for bringing it up cause i didnt even think about that when i designed it.
