And a DIY will follow.

I'll update when I get ready to install it, and it's back from the paint shop.

It's a better manifold, to replace my aging 92.

Picked up from Excess Horsepower for a decent deal delivered all the way to Abu Dhabi.

Almost done with paint. Waiting for another coat of antique silver and then clear.

The shop that did my original is closed, so it's going to be quite some time until I can add the stars and completely eliminate the fast logos.

I am satisfied with the results.

I'm running into serious fitment issues.

I am returning to a OEM style steam vent setup. Do no run one with an aftermarket -4 AN steam vent kit. You were warned.

Basically what I'm doing is capping the rear passenger side, capping the front driver's side, connecting the rear driver's side and front passenger side via rubber lines and a T to the reservoir.

Once my OEM LS2 steam lines arrive (coolant air bleed, whatever the proper term is) I'll again yank the manifold and install and hopefully live happy again.

2 ea -4 an caps installed on the driver's front and passenger rear.

Fits like it should now, super happy with the results.

So to highlight some of the fuel rail questions someone replicating my setup may have, I'll answer them with my solution for my setup, which maybe different than yours.

I'm running STS V injectors (50lb) which are a fantastic upgrade for not a lot of cash.

They are somewhat taller than the ls6 length injectors and much taller than the LS2 length injectors. I used the stock LS2 rails.

To for them properly so the retaining clips fit as they should, I had to use a spacer on each rail.

Luckily I had a full set of extra hardware from my previous fast 92, and the washers for the mounting bolts are exactly the right fitment when placed below the rail. It's about a 1/4" thick spacer.

You can mount them without the spacers, but I observed that as I tightened up the mount bolts, the upper shell would pop up a bit. I found that it put too much additional tension for my taste on the entire manifold as this could cause leaks later on down the line.

One can overcome this difficulty by installing and torquing the hardware prior to installation of the injectors and rails. But I am unsure of the injector safety clips would seat properly, and you may also observe upper shell deformation as I noted.

Just things to keep in mind if you are doing this particular combination.

I believe this sums up the non written knowledge that is not contained in the manual that comes with the manifold.

To update this and prepare anyone who does a 102 on an LS2 in the future, if you have a 4 port steam vent, uninstall it now unless you have several 45 deg elbows and lots of spare time. Just run the rear stock plugs.

Run the stock front cross pipe also.

Now back up and running and very very happy with the results.
