You have a link to this $4k blower setup?

I bought a slightly used D1SC kit and bought a cold side separately and was less than $4k. I can also buy a brand new HuronSpeed turbo kit and come in at $4k, especially during the group purchases.

Stage 1 does not mean bottom of the barrel. What you would do to a street car is completely different than what you would do to a car that sees the track much more often.

Agree to a certain extent. Take a great set of heads and cam against boost and boost will still have more capability and stomp it if done right. And on the street you want torque, which a boosted torque curve is leagues better than a big cam NA setup.

Agree, if you could get the same amount of air with high lift boost would not exist. Any lift over .600 is going to require roller rockers, which adds cost. Probably should not run hypereutectic pistons, a little detonation is inevitable with boost and detonation and hypereutectic aluminium are not friends. Get some forged pistion, lower end hbeams, a cam with .580 - .590 lift and boost it. If you want torque in the low end go with two smaller turbos that will spin up faster.

that's a good thread right there. Please bear with me in this moment but a few questions. How do I know which cc size I should have it milled to and which head gasket thickness to run?

That's go depend on your desired compression. Some guys want 10.5 compression and others want close to 12 if you plan on staying on pump gas. If you go with TFS heads on your motor give Brian Tooley one call for everything.

a custom spec cam and corresponding springs mite get you 15 more rwhp .also take the time to measure for the correct push rod for each cylinder.are the rocker arms stock ? the good engine builders put time and effort into making the valve train better ,and it can reward you with nice power gains .

The difference between the TSP Stage 1 and 2 243 heads is the valve size. The ports are the same. Not much difference for a street car.

Agreed. Even without his touch up work they are phenomenal heads and would likely kill those stage 1 heads. With the BTR magic in them... even better.

I put a set of those on a buddy's car, those heads f******** deliver.

A little more about your setup would need to be known. Like the cam sizing to determine the dynamic compression ratio, I don't know how to calculate that, I would find someone that did.

If you've got a stock 5.7 bottom end at 3.898, and you get them with 60cc chambers and use a stock head gasket you'll be at 10.9:1. With a .040 gasket you'll be at 11.24
If you went 59cc with stock head gaskets you'll be at 11.0, with .040 gaskets you'll be at 11.39

As far as which thickness head gasket to use, read up on minimum quench and make your choice, it's your build. People run the .040 gaskets and don't have issues but that puts you at .030-.033 depending on how high your pistons are out of the block. The rule of thumb is to go for .040 quench on a street car but LS motors have been running .040 gaskets for a long time and getting away with it. I don't know if everyone does, but it seems a lot of people do. Another thing to consider is the price of the stock gaskets vs .040 aftermarket gaskets. There are also .045 gaskets which is a nice in between, but those are also aftermarket and higher priced than OEM.

What heads? Is it an aftermarket casting or a cnc program?

Mast heads require offset rockers. With everything you need you will be looking at $2,800.

Add cubes or boost it. With above bolting on gains over your current config will be costly per hp

Preciate the link.

In regards to recommending them for the OP... kinda sucks they're bare heads, with everything needed they'd still be about $2500.
