whats used to make the hole for the bung

 

Mine has no bung on it at all. I just used a 1/2'' drill bit, tapped it, then used a good sealer.

 

I've done probably 30 of them like that and none leaked...

If you know what you are doing, it works. I wouldn't advise the average person to go out and stick a 23/32nds drill through thier enplate and tap it, it is easy to crack the cast aluminum and it is thin. If you do it right though, it's much simpler than welding.

 

nah im gunna stay away from tapping im just wondering what schamsy used to drill the hole the backside of the bung is 1" where do you get a bit that big, hole saw?

 

1" is gonna be the full width of the endplate in the middle...

Your hose is only 3/4" inside, I wouldn't see a reason to go bigger than that on the drilling, unless you are tapping it.

A hole saw might work, but it just seems like a bad idea to me. I use a regular drill bit with a 1/2" shank, in whatever size I need. I think the actual size for 1/2 NPT is 37/64th's, or possibly 35/64th's, not sure. Thats for threading though. It doesn't leave you a whole lot of room, you have to position it correctly to make it work without drilling into the side walls.

 

I might add to make sure that you blue loctite the bolts. I went to re-do mine after 2 years because I did not swap the tubes while I was doing my clutch, one of the end plate bolts had fallen out. Good thing it was still wedged between the manifold and the endplate. No leaks luckily but I had inched the gasket

Also make sure that you remobe the alternator bracket as the manifold will not come off unless you remove this bracket.

 

subed for later

 

do u have to swap the cores

 

yes, that's the most important part

 

i dont know **** about the dual pass im having a shop do it when they install my head just want to get my **** straight so i can explain to them wish me luck

 

Where are you getting your endplate from?

 

OTTP...Unless you have one for sale?

 

subd

 

Sub'd

 

did you need to replace the seal for the endplate? i'm getting a dual pass soon..

 

pretty sure theres a diff thread for how to install

 

No u dont need to replace the gasket, unless u rip it.

 

alright kool, cuz zach said i should, but i don't see the need in one either..

 

They are 100% reusable.

 

since you gotta take off the intake mani shall i consider changing that gasket?

 

Yes, you have an 05, you should change it anyways. Get the update one so ur dipstick doesnt pop out.

 

so since i have an 07 i should be fine with the intake manifold gasket as far as the updated one? and is that one reuseable as well?

 

Yes, the intake manifold gasket is metal and re-usable. If you've had it off many times, i'd say replace it anyway, but i've never had a sealing problem re-using one even after many times on and off.

If you need a dual-pass endplate, contact me.

 

i may be purchasing the one from sunburst lol....isn't that one you made? i want to do this but i'm afraid if i **** something up im screwed and my warranty will be gone.... i want to do this tho so my temps are cooler and im also going to be doing a h/e soon and figured just do both at the same time

 

Yep, sure is

It's not that hard to do, if you take your time and follow the instruction (there are ton's of how-to threads on here), you really can't mess anything up. Just plan on spending a day doing the work, it's not a 15min swap, but it's not that difficult.
