You beat me to posting this!

Cracking setup. And that's a proper intercooler.

The first thing I would do with this is shut down the boosted c5/6 ecs cars.

After all ecs doesn't think the c4 is worth their effort to come up with a package for.

Is this based on an SBC or LSx style block setup? I hope it's based on an SBC vs. the often-drooled over LSx motors just to prove a point.

It looks like a Gen I SBC to me; siamesed intake ports, Exhaust port configuration...looks Gen I to me.

I would take this as a compliment. I love your packages I am just annoyed that you told me once the c4 would cost too much to modify to meet your owners expectations so that's why you don't do it. Like its a bad car or something

There were more c4s produced than c5 c6s or c7s, so I am surprised you don't have a package.

There's a lot of arrogance in the newer corvette owners and in tired of all the c4 bashing occurring on this forum. It has weakened the whole community.

I hope the owner of this car bashes back!!!

I hate to break this news to you, but the only thing that represents a C4 on that car is the body. Great build, but a far cry from bolting a supercharger on a C4.

There isn't arrogance from the new owners, some maybe but not as a whole community, many Corvette owners have owned them threw each generation. Fact is that the newer cars are drastically better vehicles, simple as that.
You see the facts as arrogance which is a shame for you, not them.

ECS opened it's doors in 98, since then we have only looked forward, not backwards. So there will never be a C4 kit produced by us. Sorry.

The suspension looks stock as does everything else but the drivetrain.

Engine swaps are probably the best path for performance in anything older than single digit years.

However, there is a valid point that there's a lot of C4s out there that crave bolt on performance packages. Not sure how the numbers would work out, but it seems like a legit opportunity to support a generation of Corvette and even make some money in the process.

ECS should look a little more closely. Only parts I saw that weren't stock were the engine and auto trans. I think it's a sweet car and a sick build. Still has A/C...I dig it.

I also agree with Dizwiz24 that there is arrogance in newer car owners. That doesn't meant ALL owners, but it's there. Seen it even more so w/the C5^ Vendors.

We have a handful of ECS kits in C4's, they are just bolted to an LS swap.

Guys the biggest problem here in my humble opinion is not the car or making a kit, it's the engine management. The computer in the car is relative to it's time frame. Think of what a cell phone was in that time frame, now compare it to today.

I know it can be done, I just do not feel it can be done consistently, nor would I want to be the one tuning it. How can I sell a product and offer no support for the tuning of it? So a C4 kit will never be made here, again terribly sorry, but there is a good reason why the big name tuning software companies do not support these PCM's.

Computer swaps are getting more common and cheaper. I have a Haltech in mine, albeit still running TPI.

Do you feel it would be prudent for us to supply an after market ECU with each supercharger kit? I think that would be a tech assistance nightmare for us.

Look I just humorously jumped in here since Dizwiz likes to throw shots at us every six months or so because he is mad that we do not offer a C4 kit. I'll except that the new car owners, and C5 distributors are arrogant, if we can agree that is simply childish. Extremely childish for that matter.

Well I had my fun here, time for me to go back to the upper deck...

It would only be prudent if you ultimately make money, or at least break even (larger customer base does have long term benefits).

There's some room for opportunity perhaps, but most of the C4 crowd has resigned themselves to the custom approach.

Oh and by the way:
