Link worked fine for me. Hasn't Mr. Lutz said time and time again that they won't make one?

It's a shame you can't take pics at SEMA, or I'd have them posted in a few weeks.

Will. Not. Happen.

No reason why they couldn't put a V8 in it.

Apart from the fact it will be a suicide machine... in the words of Springstein. :D ;)

Has Mallett anounced the prices for their V8 Solstices/Skys? I think it is cool, and completely possible, but I do not think we will see a factory V8 Solstice untill the next generation (if ever). Just remember the Vette started with a I6 :) .

...uh Guy, technically thats 4... ;) :p :D

I'll take a Red Sky with the LS2 please :D!

I'll get into this in a little bit in a writing. I'll say this....Mallet usually gets their V8's from GM on this, however GM has refused to back them on this project.

Take it as you will based on that information. There is NO V8 coming on Kappa, AT ALL. Understood?

Mr. Lutz needs to be completely and permanently removed from GM !....PERIOD!!!

That didn't really show me any pricing, but thanks. After a bit more searching I found it. $18,000 for the conversion.

A V-8 also is reportedly on the agenda for the Pontiac Solstice. We've been assured by a senior GM exec that a V-8 will fit between the chassis rails. Sounds like a recipe for a 21st-cetury Cobra.


Interesting. I need to find my post where I reported that GM has one V8 powered test mule Solstice, and where I mentioned that a V8 powered Solstice would be Pontiacs version of 21st Cobra.:D

I wonder if these same MT sources can confirm that a V8 will fit in the passenger compartment of the Solstice, once the interior is removed? Will a V8 fit in the trunk of a Monte Carlo? Will two V8's fit in the cargo area of an HHR? Will a V8 fit in those big shopping carts at Home Depot?

Yeah a V8 will fit between the chassis rails of a Solstice. So what? That doesn't mean you can make an actual saleable car out of it.

f-bodys had a v8 crammed into them... and it was a sellable car... kinda...

I also agree it will not happen. Not out of a GM factory. Besides, a turbocharged Ecotec, straight from GM with a full warranty, should be plenty fun enough. :)

NO the F-bodies were designed from the start to handle a v8. Kappa was designed to handle a 4 cylinder. BIG difference.

Not so i could tell ;)

lol, its just a bit tight in there at times... but i know what you mean :)

The first thing I thought of when I saw the concepts of the Solistice was "I hope somebody puts a V8 in it."

I would love to have that conversion done.

What a car it would be.

Monster Miata Killer.:D

I will say it again. There is ONE Solstice test mule with a V8 running around GM. Maybe some "insiders" can confirm this?

Don't be surprised if you see a V8 Solstice 2009.

Don't be suprised if you don't either.

Also the v8 is probably being used to test the body for stiffness for the GXP.

Once again, there will be NO V8 Solstice by GM, not on Kappa.

Just playing devil's advocate, but weren't there guys saying a few years back that there was no way that the upcoming LS7 was actually going to be 7 liters? I remember alot of naysayers spouting that off.

I think a v8 Solstice was tested. I'm not saying they are considering making it, but I'm 99% sure they tested it.

The f-bodies even had 4 seats crammed into them..and it was a sellable car..kinda :D

Ya know we had a nice long thread about a G6 V-8. I think the same thing applies here also. It will fit. The small block chevy fits in everything from bar-stools to 26,000lb cube trucks. I dont work for GM, I'm not a future teller, but I highly doubt it will ever happen. I'd love to eat my words one day but I doubt I will.

The car will go fine with a turbo or blower. For the aftermarket a turbo ecotec could put 350hp to the wheels and still get 20 mpg easy. No cam or head swap needed.

The V-8 weighs 100lbs more, plus chassis, tranny and rear end upgrading would give you a 3200lb solstice. How much hp? 300? whats the price? 29,995? It doesnt sound all too bad but not sure if the chassis was designed for that.

Wouldnt a v8 in the solstice be a bit much for its size and weight (spin the tires to much)? I think the turbo would be a better idea. I'll take a 8 over a 4 anyday though.
Just a few of my thoughts

You do know there's also a conversion to put Ford's cammers (including the SC Cobra motor) in Miatas, right? ;)

Well, GM had a V8 FWD Impala screwed together, but it didn't see production for almost 8 years. But on the other hand, GM also had a Monte Carlo with a Sigma undercarrage running around back in 2001, and a RWD version of the Buick Regatta and Chevy Lumina coupe about 15 years ago, but it never saw production.

GM engineers toy around with stuff all the time, but it doesn't mean GM intends to market it. :)

There was also a f-body based Monte Carlo back around '97

and there's the AWD LS6 Trans AM...

From what I gather, the LS1 conversion is pretty much the most popular swap nowadays.

The LS1 swap is common in pretty much anything with 4 wheels, and perhaps 3 or 2 wheels.

If the Vette ever died, GM would have some fast ass cool cars.

BTW is was 1999 and it was Green in color with I believe an LS1. It was on the Hot Rod East Coast Power Tour at the time along with the first Chevy Nomad concept.

I have a picture of it somewhere.

Yup, that's the one..

Scott can correct me if I'm wrong, but that Green Pro Street Monte wasn't a Sigma platform....it was a F4 I believe.....I think Guy was alluding to another mule.

It was another. One that we probably shouldn't even be talking about on a public forum.

Thanks. :)

OK, no V8, but....what about a V6?

Seems to me that could be a better fit, not dramatically upset the chassis balance (like a V8 would), and at 2800 odd pounds, a 240hp+ 3.5/3.9-ish V6 would be an equally hot car. The added torque alone could change the character of the car for the better.

Of course, so would the rumored SC 4 banger...so why bother? :think:

Its getting a turbo 4. A V6 would be nicer for the low-end.

Depending how they will engineer the turbo set up, but it's possible to have 100% of the torque from somewhere like 1800 RPM all the way to 5000 - 5500 RPM. Just look at Audi/VW 2.0T engines and Volvo's turbo engines.

That was before 1999 because I remember reading the article...in my high school library...I graduated in May 1998.

That just made me feel old, but at least I can sorta pinpoint when that car was around :D

How about an Aluminum S/C HV V6? Lighter than a V8 and more power than a Turbo 4 cyl.

I'd question whether or not a V6 with a blower is less heavy than a naturally aspirated V8....

The rest of the powertrain might require more beef with the V8, but the blower probably offsets the two extra cylinders pretty closely.

Yeah, but those Audi engines aren't going to supposedly make 240hp or more. My bet will be that there will be at least alittle lag, although nothing like an Evo.

It would be nice if GM started their own direct fuel injection systems. I bring this up because the Audi/VW engines are or will be taking advantage of the higher compression tolerances their FSI engines allow, thus reducing turbo lag even more.

Soon enough GM will have DI. There are already reports of DI versions of the 3.6 HF making 300 hp. I say give GM a little time.

The STI's 2.5L turbo 4 has good low-midrange tq. It makes a nice peak of 300 lb/ft as well.

The drivetrain will be just fine with a v8. The rear end is from a near 4000 poud car (as well as the upgraded version for the CTS-v) And the trans is from a truck with at least a 5k tow rating. Im sure it can handle a LS2.

For manuals, I wouldn't trust anything but a T-56 behind an LSx, and since it's a 5-speed it isn't a T-56.

Expect 6 speeds behind GXP and Redline models ( I think I remember that right, I'm getting old :think: ) Let's see what the turbos are packing before we start the "there's gotta be a V8 in this car to be fast" talk. When the aftermarket catches up with the turbo ecotecs, there will be no issues with sky high power numbers.

A little tidbit...peak torque on the FI motors will be well under 2000rpms and flat as a tabletop. GM powertrain really outdid themselves in tuning on these beasts.

A very good point.

The only issue will be whether the supporting cast is up to the task (chassis, transmission, rear end, driveshaft, clutch).

But that' s the great thing about turbo cars...the initial hit isn't as brutal, so drivelines
"should" hold up better....

Hmmm...

I have to think about this...

The way I got this figured, 400 ft-lbs is 400 ft-lbs. Now, that might be very wrong, so I shall put my dunce cap on and ponder...

Go sit in the corner young man......of course it is, but most driveline failures are during the initial hit....you know, trying to move 3***#'s from a dead stop is harder than pushing it faster after already moving.......come on now, I'm just playin' Mr. Optomistic..... ;)

I guess you have seen the little beast or at least have seen specs, good to know they are really out there. I would expect the 6 speed to be the same as the one behind the 3.5 VQ in the 350Z and G35, am I correct in my assumption?

You know if the roles were reversed (well maybe not with you Doug) Pacer would be ripping some butt over such oversights. But that's ok, everyone has thier bad days ;)

I think it goes in this order (don't take this for gospel, I'm not 100% on this): turbo ecotec-->T56 (not sure which build)-->sigma-like IRS

I don't see much issue durability-wise. Traction may be another thing altogether...

Not sure what is behind the FM's...

A quick google search showed an Asin transmission behind the 3.6 HF in the CTS so I guess that is what we will see. Should quite those who don't like the 'truck like' Asin 5 speed.

it doesnt need a V8,

its needs a forced induction 3.8 - 4.3. 250HP in that car would be absolutly unarguably more then enough.

Hell with a twisted 3.8 in it, i might actually consider it.

Who says you can't get that (and torque) from an Ecotec???

Meh, im young in age, but old school in engine beliefs.

Cubic inchs is the only HP ive come to know, or trust.

a 9 cammed, 6 ignition packed Inline 5 with a cool plastic intiake isnt the type of thing i think about when i think of HP.

:shrug: but im sure its quite possible.

The tranny in the Solstice is the Aisin AR-5, the same one found in the Colorado/Canyon. I dont know if the internals are the same, but the Colorado's is only rated to 255ft-lb.

Its the same trans from a Colorado. But it rated at that tq in a much larger truck thats ment to tow 5000 poulds. in a 2800 lb roadster it could handle a lot more.
