blue print for 700-800hp in ls3 long term

[perfxn]

ok, i havent any knowledge about hp or engines. All the knowledge i have comes from this site. My questions is what is the best way to get your ls3 camaro to around 700-800hp range. I plan on slowly upgrading my engine and power over a 5-10yr span. one of my concerns is wasting money a labor. i would like to only buy parts once, not add parts and get to much power and have to replace them. waste of time and money. I was hoping some one has layed out a blue print as how they are going to build their ls3. I dont know if this is totaly possible or almost "meaing there will be some waste while upgrading" of course times are hard end every one wants to waste the least amount of money as possible. I pan on printing this out and taking it to some mechanics and getting prices and their views.

thanks for every one incite.

You might want to read some threads on it first.

Your not going to get 800 hp out of an LS3 without totally rebuilding the engine. Not bolting on parts. Even then with all forged it could blow on you so assume your plenty rich to just toss in another rebuild etc.

Might want to read up and revisit your numbers.

7 or 800hp is a big step. I am not an engine expert but that will require alot of internal work. Not sure if you want to keep it naturally aspirated or not. Block work, cam, heads, ignition amoung other things. Some of these other guys on this forum are hp experts. Maybe they will chime in.

vash, thats exactly what im asking as how to go about it from the start to finish, rebuilding, getting forged pistons the whole nine which ever is teh best way to go. I ahev read post but there isnt any that totaly explains the whole process, step by step , im looking for a detailed description. thanks for who ever has the time and knowledge

There is no way to slowly build up to 700 - 800 hp and not end up wasting some money along the way IMO. Maybe work on doing full exhaust, THEN pull the motor, throw some connecting rods and pistons in there that will hold up (maybe the crank too, the stock piece may work though) and then boost it. I don't know many LSx guys running 700-800 hp, most guys I know are in the 550-600rwhp range. Maybe they can chime in.

IMHO, Save yourself the hassle and buy a LS9. It has all the little tricks done to the block and is engineered for supercharging. It comes from the factory rated at around 638hp. So it wouldn’t take much to add an extra 100hp and still be reliable.

From GMPP;
“GM Performance Parts is thrilled to offer the LS9 6.2L in a fully dressed
crate engine package. And while it shares the 6.2L displacement of other LS
engines, this one is unique, with stronger block casting, stronger cylinderhead
castings and steel cylinder liners that are honed with a deck plate
installed to maximize performance and cylinder sealing.”

ive read you can basicaly turn a ls3 into a ls9 or lsx with pistons and some more stuff then you could get up the 700-800hp range with out hurting the engine.

Good luck with that. You are going to be throwing a TON of money away imo. More power to you if you have the money to blow.

That's a big question and I'm by no means an expert, but I'll take a stab at it. It's hard to slowly mod to this level without replacing parts as many parts work better for different applications. A cam for instance, naturally asperated cams are much different than a blower cam, or even a nitrous cam. Or 1 3/4" headers are probably best for N/A power, but 1 7/8" will be best for forced induction. Or lower gears are best for low to mid power levels, but as you add power you want a higher rear gear, especially for a turbo car. Bottom line, you will end up replacing parts. The only way to get around it would be to mod in large steps. Exhaust first, then suspension/tires, then upgraded diff, trans, and clutch, then forge the motor internals. After all that's done, you can finally add the cam/heads/supercharger or turbo. You have a lot of work and money to put into it before you can safely run that kind of power.

If you want that power level and an ounce of streetability I'd say you need to go forced induction (supercharger or turbo). I'm a fan of supercharging so I'll go with that.

-All forged internals (pistons, rods, crankshaft)
-TVS 2300 supercharger / intercooled
-Cam with specs for blower application
-Ported heads, possibly with larger valves
-Dual valve springs
- Titianium valve springs
-1 7/8" long tube headers
-Mid-pipes with high-flow cats
-Cat-back
-High pressure fuel pump
-Larger injectors
-High flow oil pump

With all that power you need to put it to the ground without breaking things:

- Clutch
- Possibly upgraded trans
- Possibly upgraded differential
- Half shafts
- Wide and sticky tires
- Springs
- Shocks
- Subrame connectors maybe
- Bigger brakes possibly

Some of the engine upgrades are available now since the LS3 has been in the corvette for over a year now, but the other mods will take longer since the camaro is new. If you add power without upgrading the rest of the car first you're risking breaking parts.

In the build of our Camaro we are planning to cover this subject.

We will try it from several positions.

1) LS9 with an aftermarket TVS2300 and fuel system

2) LSA with an aftermarket cam and fuel system.

3) LS3 with Lunati Forged crank, rods and Diamond Forged Pistons.

The last will use the GM Performance Parts CNC Ported Heads as well as Bassani long tube headers.
We will look at several of the aftermarket superchargers such as the Edelbrock, Magnuson and Harrop TVS 2300 with the Eaton Rotors.

Camshaft isn't very important as the blower and intercooler is where the big power comes in.

A rear axle conversion is in the plans when we make the big power.

^ I can't F'n wait to see what you guys come up with.

thanks!!

I already had #3 included in my "3 year mega-power plan", year 2 winter project I think, I'll be waiting to see what you guys do there.

Robin, are there any plans for a supercharger upgrade package for the SS from GMPP like the Mustang has? Thank you.
