+1 for whoever mentioned GM switching cams in the LSA for the Z/28 release. What I'd like to see (and am holding out for, you might say) is a cam profile that pulled higher in the RPM band, similar to the Z of old. Seems to me the heads, and hopefully the pistons, would be able to hold up. Combine the higher-revving LSA with suspension and gearing... oh man! On that note, there hasn't been any news about possible suspension mods?

If the LSA does really make it into a Camaro 2 years from now, look for the car to top 4100 pounds.
lets just hope GM does something to make that front end LIGHT! Just so that LSA or LS7 with a nice upgrade in power will make it into the camaro, but on Motor Trend's site they said the LSA was already planned to go into the Z28 but hell I wouldnt mind... just some carbon fiber fenders and a carbon fiber hood and make a carbon fiber front end if someone will make that

The LSA seems to be a complete forged bottom end engine except for the pistons which are still stronger than normal LS3 pistons but not the forged ones from the LS9. The LSA has a 1.9 cu in supercharger compared to the LS9's 2.3 cu in supercharger and increased cooling bricks in the intercooler, which when coupled with the forged pistons require's a slight increase in hp to operate compared to the LSA.

This is what i take away from the info provided and input from "Uncle Robin Lawrence" on the benefits of the LSA.

I remember the "Fbod Father" mention at the Indy gathering saying that GM would never loose a hp race nor a performance race with Ford's mustang.

If the LSA is going to be the motor going in the Z/28 GM needs to go ahead and add forged pistons.

The hypereutectic pistons are not going to cut it.

Then expect the price to be equal or greater than the GT5000

GM mite as well make a whole new engine for the Camaro if they decide to do that

... What about the dry-sump LS3 that's in the Grand Sport ?

I would expect a LSA powered Z/28 to be priced very close to a GT500. That is what they are going after with the Z/28 in the first place, or at least that is how I understand it.

Don't know much about the dry-sump LS3 in the Grand Sport.

Not to be a know it all, but the engine goes for roughly 21-22k.

Exactly! I have this little honey for sale at 22,000 with the accessory drive components.

Robin, if you had an LS9 on hand, what made you go with an LSA for your car? Would the S/C housing on the LS9 have to be modified like what you did to your LSA to clear the wiper tray?

LOL that is a GREAT question. First I was going to install the LS9 in the car. But the guys at GM Performance Parts felt that since the LSA would probably be the choice of engine in the rumored Z28 I should use the LSA.

Since the LS9 manifold is lower it does not require any modification to install in a 2010 Camaro. The clutch would also work easier compared to the clutch that comes with the LSA.

On one hand I was told they wanted to see the true performance potential of the LSA. Later I was told that they had wished that I had left the LSA engne stock.

The LSA is a great engine and I have learned a bunch about the potential of this engine.

One more question, then I will talk with you more at the fest. You said the LS9 manifold is lower and would fit the wiper tray, can it be installed on an LSA engine without modifications?

Yes and no, the bolt patter is the same for the tops. The LSA and the LSA have sensors in different positions and the fuel rails are different. For that reason you would need to make some modifications,

The LSA uses 1 square intercooler towards the rear or raised portion of the top. The air from the TVS 1900 goes straight up then makes the turn after passing through the intercooler core. The core sits on a square rubber gasket that is in a recess in the lower manifold.

The LS9 uses 2 intercooler cores that sit to the sdie of the opening of the TVS2300. The air makes the turn before the intercooler core. The LS9 lower has 2 rubber gasket strips that run the length of the manifold.

If you were to use the LS9 top on the LSA lower you would need to make some seals to close the gaps from the different gasket configurations. You could rig something up pretty easily but the efficency would suffer.

Here is the kicker, the LSA intercooler is less restrictive and more efficiant that the LS9. That statment should cause some LS9 huggers a little heartburn.

My thoughts.....of course

Robin

Compact packaging comes at a cost...especially in a car as tight as the Vette...


*hugs tighter*

Actually to save a lot of work we looked at using the LS9 upper to get the car done. Some people felt that if we used the LS9 top people would think that the engine was an LS9. There were many LS9 2010 Camaros already completed.

From what I know there are only 3 LSA powered Camaros.

1) The first is a mystery car that I am sworn to secrecy
2) The second was my car
3) The third is Conrad's BIW LSA Drift car
4) anyone else???

For those who don't know and have doubted the LSA here is a video of mine taken yesterday.

Old Jedi had a ride at the Fest, he knows
