When you modified (welded) your stock VLOM, did you have to remove all of the rubber stuff on the underside? If so, how did you go about removing it?
The solenoid tray has like 10 or 11 torx head bolts. Remove them and take the solenoids out then remove the solenoid retainer plate and the gasket will come off. Pay careful attention as you disassemble the tray.

Good to know everything works with the ls4 fuel rail. Got the spacers in and everything fits wonderful. My only concern is the entry of the spacer, its centered and the ls4 rail comes in at a offset angle so I will drill out the inlet to mimic the factory fuel injector inlet. to make sure there will be no issues. using a step drill is ideal for this but you could always use a drill bit.







Using a spacer for the rails isnt neccesary however if you wanted you will need a approximatley 12mm spacer.

Yea I ordered the fast ones to however they fit on the bottom of the injector which is retarded. So I looked on ebay . I'll post the link when I get home.

EDTI: heres the link

fieroguru already laid out what injector spacers and fuel rail spacers are "needed."

I'd get them versus having those bolts sitting like that and having the fuel rail floating like that. They're very cheap too.

Theres more ways to achieve the same thing. Think about something why would my rails be floating around the bolts hold the rail down on the injector spacers and fuel injectors. There's compressed like they need to be in the intake manifold. There's nothing floating around. And if you read thoroughly through my previous post you'd see where I mention spacers and the size if you need them.I'm smart enough to know that my fuel rails shouldn't float. Try for youreself.

I'm just pointing out that fieroguru already explained what would be needed.

It also makes good practice to have spacers so as to not over torque those bolts. Without the spacers, the rail "floats" due to the tension of the rail.

These work great to mount the LS4 fuel rail to the LS2 intake and cost $2.30 each or less than $10 + shipping. Then you can either run the LS4 injectors with the injector spacers or the longer LS2 injectors w/o spacers.

Once you ditch DoD, the LS2 intake/TB/MAF swap is pretty much a bolt together upgrade. Sure the LS6 intake is better, but simple and lower cost have their merits too.

Yea but theres a multitude of spacers to choose from on ebay, i just posted the correct ones used after making the mistake of ordering the p.o.s F.A.S.T ones. as for the spacers yea, thats why i mentioned them in my post. The FAST ones go on the bottom of the injector. Not even sure why they sell ones like that. and as for the proper ones i still think there is work to be done on those which is why i made the note to bore out the openings to match the fuel injector openings. There are also other issues i posted about in previous pages..

Awesome, I just bought that same valley cover the other day for my ported LS2 swap. Also paid $42-43 shipped for it. Cut off the OPSU bung, tapped the hole, and plugged it with a 3/8 NPT plug.

I'm going to be feeding my OPSU with a 4AN line from the little oil bypass cover on the oil pan by the filter. Just need to pull that and drill/tap it.

Going to use the stock LS4 fuel rails and injectors with the FAST injector spacers. They look to be exactly the right height.

I'm too cheap to pick up an LS2 TB for now though so I picked up some 5/8" aluminum to make an adapter out of.. I just need to find the time to do it and then swap everything on.

Hm, while I also dislike the idea of the FAST spacers going on the bottom of the injector, it doesn't seem like many people had problems using them, and I figure I'm just using stock injectors and not expecting to make any sort of big power.

I'm curious to know what you're saying about them not fitting though. They looked to be the exact right height to me.

The link I posted a couple posts above. The reasons the fast ones suck is because they can potentially alter fuel spray pattern And spaces the nozzle farther away from the intake valve. Those parameters are calculated for in the pcm. Long story short just buy the spacers that go on top

Btw the oil bypass can be ordered at improved racing.com

I dont like NOT having the keepers on the injectors. I made my own adaptors to incororate the keepers.
The reason FAST designed there adaptors to be under the injector is for satefty and liability. there is a vacuume on the underside of the injector and 60psi of pressure on top of the injector. FAST did not want the blame for a leaky injector adaptor spraying fuel over the top of the engine.

I'm not talking about the fuel injector spacers.

You cannot use a non DOD valley tray with DOD lifters.
Search... Search....Search....

Just a friendly hint. I learned the hard way

So I started to tear the car apart yesterday figuring I had 4 day weekend and word be a good time to do the swap. Well I gathered the parts and started into it. Then realized I didn't grab my OPSU. Which lead to search and turned up nothing. I have no idea where its at, so I need one. If anyone has a spare let me know.

Edit: I meant DOD sensor, nor OPSU
