I will when i pull the motor to paint it. This swap will be much cleaner then my suburbans swap. I hope it runs better too. I should have all the vss crap worked out by then.

[68GMCCustom]

oh ...your just mocking things up right now?

[85burb]

Yes. Cause i was not really sure where to put the turbo stuff. Yall like the crazy scrathes in the fire wall. I bet the chain broke or something when the po put the motor in. Cause the ac box was also crushed in.

The only thing i dont know what to do with is the exhaust. I really dont want to spend 600 bucks on doug thorlys again to put a trubo on it later possibly.

Plus the coating at 250 or so. I found some shortys for camaros that are 199 and they are stainless I am trying to make up my mind about.

I wouldn't worry with coating them. But that's just me. Would offer better performance than shorties, too.

There is no way I am putting painted headers on. One trip around the block and they will be bare. And I may be putting a turbo on it still. Not looking to spend lots of money on something I am just gonna take off.

my LY6 manifolds are just sitting in the storage building. a bit heavy to ship tho. I'd take a lil' trip in the old truck for fun if I had the vibration fixed (for which I have a plan)..... if you weren't so dang far.

to give you an idea of how they fit:

[85burb]

Got some done today. Got my tps, iac, and fuel rail fittings in the mail today. Removed water pump and installed the ls1 intake.

I ordered some more parts to night. Ordered a throttle cable and bracket and bolts. Also ordered a throttle bracket to my suburban. Nally buick online parts is a amazing web site. Great drawings of the parts and good break downs. Also got a seat belt bracket for the wifes new gmc.

[85burb]

I was looking at the vette fuel filters and i was thinking about the way i need to run the fuel lines. One from tank to pump to filter. one from filter to tank. The one from filter to rails and a tee on the passenger side rail that a short hose goes to driver side rail. Will that work?

If you're going with a turbo setup, I'd strongly consider putting together a return style system with a regulator up near/on the fuel rails. Much better setup for a turbo with the boost referenced regulator.

[85burb]

Yes if I do put a turbo on it will for sure get a return system. But I can't find a decent priced fuel pressure regulator. The lowest I found was over 100 bucks. If I can find one around 50 that is what I will use now instead of the vette fitter.

The stock truck setup works great. It's not as pretty since you need to use the truck intake instead of the LS1, but it's VERY cheap, and good for around 500-550 rwhp.

[85burb]

The harness I have has car set up with wire routing and injector plugs.

So what pressure does the regulator need to be for. Will a 30-65 psi work? Many them things are expensive.

[Wasted Income]

Your fuel pressure should rise at a 1:1 ratio with boost.

Example: If your base fuel pressure is 58 psi, at 1 psi of boost, it should be 59 psi and at 10 psi boost, it should be 68 psi.

Doing it this way makes it easier to tune, since your injector flow should remain constant.

[85burb]

Ok i will order that fuel pressre reg that i seen cause it will have no boost for a while.

On a side note i got in the cold air intake kit today. Looks like a nice kit.

[85burb]

Test fitted the intake today. Also installed the egr plug. Not sure on where the intake pipe will end up after the water pump and hose is installed but this is where i want it to be so far. Need to order the rubber clamp that the maf goes in to mount the air filter. Got the part number already just have to call the local gm dealer.

[85burb]

I got the gen 4 water pump in the mail this weekend. Test fitted it and it is like it was made for the swap. Fits like a glove. Also figured out what i am going to do with the intake pipes. I put the belt on just to make sure the intake pipe will fit around everything. All i need now to test run is the fuel system.

[85burb]

I got the throttle cable and brackets i ordered the other day finally.

[79shortbed]

Love the progress man! I am doing basically what you are. I may go turbo in the future, or 383 with H/C/I. What is the part number for the water pump you used? I'm going to use an LS6 intake on my 5.3 if I can get one reasonable.

[85burb]

On idea on the part number. It is a 08 gmc water pump. Got it off eBay.

Part number on that pump should be 19208815
