Just wondering what my options are here. I have a 2000 ls1 whith a stock intake 243 heads and a cam, i will be installing my fast 92mm intake and tb soon. i would like to keep all 4 steam vents functional. What are my options?
I have used the stock LS1 steam tubes, I removed from the vehicle and lightly tapped them down until they where oval against a anvil/vise. Check before you torque down to make sure they clear. I have done this twice without problems.
I also had to bend the driverside front stream tube so it didn't contact the front edge of the intake.
I have heard of people cutting the tubes and running rubber hoses around the intake to the front.
instead of doing a y connection like others have done, I machined up a distribution block today so that I can keep the hoses right next to each other to keep everything routed nicely. I am thinking about doing it differently though. I made this one on the lathe, but when it gets warm this spring, I can make a nicer one on the mill.
Run a truck crossover in the rear (they point up and away from the firewall) , ls6 crossover up front and "T" together under the TB
$50 for everything, less if you have some parts already
$20 used front ls6 crossover
$20 used truck cross over
Pack of worm clamps $3 Home Depot
Coolant hose autozone $1/ft
Brass T Home Depot $2
Dorman coolant crossover gasket set of (4) $4
The hose runs from the rear crossover where the factory pcv hose ran near the intake base and curvs around the intake and under the TB and meets the hose from the front crossover
Nitrous outlet and the Kurt Urban setups are both nice.... I partial to the KUP setup (obviously ) because I think it looks better (I have the optional bracket, looks ****). One thing to note, though- The KUP setup does NOT come with a return line, so how the steam return is handled is up to you- which I prefer. I made my own line and used a jagsthatrun piece for the return, and added a bleeder valve at the same time. I'm pretty sure you have to tap the water pump for the Nitrous Outlet kit.
you can push it down depending on the valley cover that you have.
5 axis lathe sounds pretty damn nice. I just have an oldschool southbend heavy 10 toolroom lathe from the '70s.
I will either mill some flats in it for a wrench, or make a nicer one on a mill. But I made this one with very little time, and used fittings that I had laying around. I will replace all the fittings with nice ones later on. Only cost me around $1 to make. It'll do the job
That looks really nice, i want to try to keep it small, i will prolly use stainless and get a real nice finish out of it
I agree that its pretty big. I already purchased different fittings and may be able to get it half this size. I made the body out of 2024 aluminum, want to keep it as small and light as possible while still keeping the same amount of flow.
Stainless will look really nice. Be able to buff that out like a jewel
