60mm Throttle Body on HO Factory Intakes? July 12, 2006, 10:31:03 AM Looks like I'll be going to the parts yard. The Mustangs are few but I know they have several HO intakes on some other Fords (most intaking on the drivers side). If I am looking for a 60mm intake/EGR spacer, what vehicles (other than 'stangs) do I need to be looking for? I mean, if I find an HO in a Lincoln would it be an acceptable 60mm? Forgive my ignorance but this stuff is a lot different than the old FE motors:shakehead ! Quote Selected
60mm Throttle Body on HO Factory Intakes? Reply #1 – July 12, 2006, 11:32:31 AM Only HOs are in the LSC Lincolns and Mutangs. None of the full size had a factory HO, so if if it has the driver side T/B its gonna be the small 50mm... The '91-'93 Birds/Cougs have HOs but used a different configuration... Quote Selected

Id like to see someone make use of it cause its going to the dump here soon.It could be adapted to a 5.0,,3.8,, or your automatic cat food despenser is you so choose:D .here is the wild a@@ looking intake you can spot a mile away, only engine i know of with this intake.speaking of adaptablity, the heads on the 4.2 bolt on the 3.8L and all ports match up. So.....that means all this junk from heads/upper,lower intake/ect ect bolt right on. THe valves in these heads are really larger than what i expected. They mic around 1.45/1.68 Quote Selected

I can see where it would cause limits the other way around. If it isn't an issue I'll be pretty much set - otherwise I need to find a 65mm EGR w/spacer to match the TB. Quote Selected

60mm Throttle Body on HO Factory Intakes? Reply #9 – July 13, 2006, 07:31:00 AM Yea Scott a couple mm lip ain't much, but subtract that from the diameter and all of a sudden that 64mm TB just became a 60... Being basically lazy, I sure wouldn't try to adapt some oddball configuration when Stang and LSC units are easy to find... Quote Selected

If it isn't an issue I'll be pretty much set - otherwise I need to find a 65mm EGR w/spacer to match the TB.On a stockish SO 5.0 a 65mm is a total waste... But to answer your question, no it won't make any difference(again on a stockish 5.0). On a high RPM engine it could create turbulence that may restrict total flow... While I'm at it.... A HO intake ain't going to make a tenth the difference that the 60mm TB/EGR spacer will make(which won't be much either)... A SO intake has approx a 58mm opening anyway(yes I've measured them). IF you matched the intake opening to the 60mm spacer/TB you'd have at least 95% of the improvement of the HO and 60 mm... The intake mods arn't going to do much without a set of headers and free flowing exaust system... Quote Selected
60mm Throttle Body on HO Factory Intakes? Reply #11 – July 13, 2006, 08:53:04 AM Thanks. All I need to get then is the 60mm or 65 mm TB. The HO intake will be here next week. I have already installed true duals, h-pipe, no cat, flowmasters - and removed the airbox. I'm putting in stock Mustang headers after the intake is done. Just looking for a little better performance and for the motor to breathe better. Quote Selected
60mm Throttle Body on HO Factory Intakes? Reply #12 – December 26, 2006, 03:14:24 AM what if your running the 65mm right now but your upper intake can do 70mm would it be worth going to a 70mm i have the HO heads and im running duals all the way so im pretty sure its breathing good. Quote Selected
