noob explorer GT40 intake question

[roadwarriorP72]

I have a spare explorer Intake lying around that I have thinking about using on my vic and i was wondering if I can use the stock Egr spacer milled out or do I have to get a lightning one? somewhere I dont recall if it was here or CVN.net they said the CV egr spacer wont seal or something. also has anybody ever tried the Explorer injectors in a stock vic or do you have to change to a different ECU or convert to MAF? possibly later when Im done with the new motor and EFI conversion on my 72 mustang I might look into this for my vic too.

Im looking at doing the HO mod and just got the new intake from a mustang, and the guy gave me an EGR spacer, not sure if its lightning or not, but as far as im aware you dont need to go to MAF because I had a question about that too, and was told it was not necessary but left you more room for later aftermarket stuff, at least that is my understanding.

If the explorer TB is much bigger than the HO one I bet you need the lighning spacer.
Pretty sure I read on here that the LOPO spacer can't be bored (and seal) anything bigger than an HO TB.

[91grandmarquis]

Yeah I remember one of them couldn't be bored, mine matches the HO upper is all I know.

a bored out panther egr spacer wont seal, that has been confirmed
need a lightning egr spacer, or modify a mustang 65mm egr spacer so that you can bolt up the throttle/tv linkage bracket

Accufab makes a blank EGR spacer in almost any size for Fox Mustangs. It's $95, which I believe includes gaskets. Get that, then drill and tap it to have studs on the back that will hold a stock CV cable bracket. Again, it's blank (solid) so as you go bigger you can just bore it out as needed.

Can't change the injectors unless you change the cam and ECM as well. Installing bigger injectors will dump way too much fuel into the engine with an ECM that expects a 14# unit. You'd be over-fueling by about 35% across the board.

Explorer intake may be a bit much for a stock motor. Probably won't hurt, but for all the trouble of swapping it, you're halfway to switching the cam out. Doing both at once will make a difference, even if you leave the stock heads on.

thanks guys for the help

I think for the time being im gonna leave my vic alone til i finish my mustang. but now that I know whats involved as far as parts needed to do a HO conversion maybe later on I might.

Thats what I said.... But Ive already got half the parts and Im ordering heads friday. I got the mercury blues.

haha good to hear thats great

could you bore out the lopo to match the explorer tab and intake, than tig weld the seam from the inside on the coolent end of it to the TB and grind off the little extra weld? she would certainly seal that way than i would expect the exhaust side would seal fine?

[gadget73]

The groove isn't really the problem. Its the flat mating surface where the throttle bore actually is. Bore out the lopo spacer too much and that mating surface is just too narrow to get a good seal.

[merc91]

if you skip the gasket on the coolent mating surface and join the TB and EGR spacer by welding the seam from the inside that would work wouldn't it? if you took your time and kept things cool to prevent distortion and setup the welding rig for 1/8 penetration or so would it work? than you would just have to rely on a gasket for the exhaust side mating surfaces.

[pantera77]

I think I'd just modify a generic 65mm spacer before trying to weld to chunks of aluminum together.

[gadget73]

if you're really good and can weld aluminum without messing it up, and without distorting or cracking anything, yes it would work. You'd have to be very sure not to distort the throttle body though or the throttle blade won't operate properly, then you'd be left with having it lathe turned to true it back up, and hope that it doesn't remove too much material for the blade to effectively seal at idle.

For all that bother, you can just fabricate a bracket to bolt to bolt your stock throttle cable bracket to a Mustang style spacer and simply bolt the parts together like it should go.
