Turbo LS3, 8lbs 640 hp

I'm looking into making Turbo kits for the V6 and V8 Camaro.

The V8 will run at 8 lbs and produce roughly 640 hp.

We are looking at roughly 3950 to 4350 dollars, which will include;
1 handheld tuner with a preset tune,
1 set of cast iron manifolds (ceramic coating optional)
1 crossover pipe
1 Downpipe with Y
1 turbo (specs not confirmed yet)
1 wastegate (possibly internal)
1 blow off valve
intake tubing, connectors and clamps
innercooler tubing connectors and clamps
Front mount innercooler
Adjustable Fuel pressure regulator
Boost-a-pump type fuel pump (if needed)
Injectors (if needed)
A-pillar boost gauge
basic turbo timer
turbo oil lines
oil line adapter to oil filter
misc fittings.


We need to sell 12 kits to get them into production. A site donation of 50 dollars will go to CamaroZ28 with each sale.

if you're interested let me know.

Just curious...why cast iron manifolds?

Cheaper, more durable.

retains heat better, more heat means less turbo lag, cheaper than ceramic coated

Is that rwhp? What type of turbo and size? I think you left lots of information out of the equation....

Make me one for a 2005 GTO and I'll buy it.

That's because it has yet to be built. Is the Chevy stated HP rwhp?

The kit will come as a complete turbo system, it will be tunable to much more than the stated hp, because the boost level can be changed along with other parts of the owners vehicle. The number stated is a estimated number based upon .5 bar or 7.5 lbs psi above atmosphere with adequate intake charge cooling. Meaning, with the right size turbo and innercooler as well as the correct fuel upgrades and timing, the motor will make that power.

Is the kit currently under development as we speak? It is still in the research stage. Meaning no wrenches have been turned yet.

Not exactly. We had an interesting discussion of thinwall vs. thickwall in the forced induction forum not to long ago... https://www.camaroz28.com/forums/sho...d.php?t=676826

Well it's the exhaust pressure which spins the compressor, not the heat. Exhaust is hot, a byproduct of the combustion process and actually a big waste of energy, but until it can be turned into energy efficiently (other than running a steam engine off your exhaust manifolds), it is there no matter what.
Ceramic coating can be used on cast manifolds as well.

Using cast manifolds makes it easier to make a good quality part.

Without forged pistons you are stuck at 8 lbs of boost ... 640 HP is an OK number but 15 lbs of boost would be real fun ...

We'll talk about that (forged pistons) later.

"640 HP is an OK number"......... ? Are you mental? 15 psi would equate to around 860 hp if the intake charge is properly cooled and enough fuel is added. 860 HP. EIGHT HUNDRED and SIXTY. I guess I know who wants to be the test pilot.



On a more serious note, I am going to talk to an investor in the next couple of days. One option is buying a test vehicle but a more likely option is finding a guinee pig.

The hotter the exhaust when it reaches the turbo, the more pressure you have to turn the turbine.

id be interested in being a guinee pig for a turbo kit. i was going to purchase headers for my car but have been concidering turbo systems against superchargers. pm me if interested or email me.
