Explorer Intake/Heads?

I have the Explorer intake & TB, it is an excellent choice. The heads are good too for a budget upgrade.

For a killer street combo, have Tmoss port the lower manifold and Thumper460 do the heads. You could see an easy 45-65 or more HP increase with both ported & installed

I don't know about the long tubes, but the GT40P's have some problems with spark plug wires clearance in the header area.

here are some other budget upgrades from the junkyard...

Gears - 87-88 T-Bird Turbo Coupe rear axle - disc brakes and 3.55 or 3.73 gears in one package for $125-$300. Add another $100-$200 or so to complete the brake upgrade.

94-95 Mustang GT MAF - $40-$100. It is 70 MM instead of the stock 55 MM on regular stangs built prior to 94. It uses a slip on duct on the side that goes to the throttle body and a 4 bolt flange on the other. You need a $25-$35 flange adapter from Pro-M to fit the stock slip on air ducting that goes to the air box. Wiring plugs right in with no changes. *1

95-97 Ford Explorer intake manifold & throttle body $150-$300. The intake manifold flows 220 CFM +, much better than stock. Throttle body is 65 MM, bigger than the 60 MM on stock stangs. I got a 96 with EGR passages that match the stock setup, so my smog gear works just like factory. You’ll need a 65 MM EGR spacer & new gaskets for $65-$90 so you have a place to mount the EGR & throttle linkage.

3G alternator from 94-95 Mustangs or other Ford. $20-$120. A must have to make the electrical system work like it should. You’ll need a 4 gauge power wire and a 125-135 amp fuse to go with it about $15- $30.

Lincoln MK VIII electric fan -$40-$160. Free up some HP by not having to drive the stock fan. The 3G alternator upgrade is a must have prerequisite before you do the MK VIII fan. You won’t have enough electrical power if you don’t do the 3G upgrade.



*1.) Pro-M has revised their website lately, but here's what I found for the MAF adapter flange.

I got a metal one from Powered by Ford for $35 and tax. That was about a year ago.

The heads and intake are definitely a good upgrade over stock. Talk to tmoss about it. He has something like 250-260hp still using the stock cam, along with a large amount of torque. I will most likely be getting an explorer intake soon for my setup.

jrichker: would you happen to have a link to the site that gave all the mass air sizes for the different ford vehicles and what curves they have?

I was thinking about going the explorer intake/heads route, you dont have to do anything special to them do you? just bolt them on?
