explorer u/l intake swap

[91GMLS]

i was just wondering about how much extra hp will i gain with this swap. i can get them for about 150 or its not worth doing sorry im a noob when it comes to cars

The absolute first thing you need to do on any of these cars for power's sake is the exhaust. Dual H-or-X pipe gains you around 20 hp at the motor. They only had 150 hp from the factory.

Check the sticky at the top of this forum (HO conversion). It will guide you to gaining some hp for relatively little $$$.

It's not really as simple as just plopping it on...

But if you do? On a bone stock engine? Maybe 10 horsepower.. maybe.



In general, the intake is the third biggest restriction. Heads and exhaust (including the exhaust manifolds) should both really be upgraded before you see any worthwhile gains from an Explorer or Mustang intake.

On a stock lopo? Nothing. In fact, it will be a downgrade.


Stick to the HO upper, EGR spacer bored to 63mm, and HO throttle body.

so order like a mustang cat-less h pipe? if so where would a great place to order it from? how would a mustang short headers with the cat-less h pipe with flowmasters 40 series or glasspacks and a ho throttle body and egr spacers would that be an ok setup

Looks you havnt read the sticky yet ,but I would reccomend looking at a mustang board for your parts.
First two things exhuast and gears. To take advantage of the expo intake I reccomend gt40 expo heads or gt40p heads.
For headers bbk shorty 1515 headers they will fit expo heads .p version included.
Just a rec,comendation. Also 2.5 inch pipe works rather nicely.
Also any swap you do will require modding the throttlebody lever. The egr spacer can be bored,or an aftermarket one can be modded for fitment as well. The only other thing would be to find an elusive first gen lightning egr spacer.
Not to discurage but do read up a bit and ask lots of questions before attempting.

thanks alot i probably swap the motors since i found a cheap explore with motor for 250 and only 112,xxx miles it drives and shifts really good all i will need to do is change the lifters and get a mustang ecm with bbk 1515 shorty headers and mustang off road h or x pipe and i should be good to go i also have a question with the maf sensor if i do this mod will i need it just curious

a few guys have done the swap with an explorer cam in the mix and had their cars run... the rest needed MAF (matching computer as well... A9P/A9M/etc)

Shouldn't have to change lifters its a rollermotor as long as it hasn't been beat to hell and back you can use them just fine.
I would reccomend using an ho cam as the explorer seems finicky ,some swear by it and some like the ho I prefer the ho bumpstick myself.
You will need a mark vii ecm or a stang one. Once agin please read the sticky! There is also maf conversion on hbere too, although it is advised to get a maf wiring harness as it is more plug and play freindly. Oh if yhou ever plan on nitrous forged pistons are a must. Which is why I prefer a ho block.

Expo cam with stock gears, H.O. cam with deeper gears. IMHO

[91GMLS]

im thinking about 355 or 373 gears haven't decided yet. what would y'all recommend? will a explorer rear end bolt right up?

[86VickyLX]

No. Go find a box limo and steal the rear from that. It's most likely a 3.55 trac lok. Just rebuild it and install it.
As for the intake swap. On a lopo, I forsee an engine running ridiculously lean. Too much air.

[zoomie]

Fyi every limo axle I've seen has the k code 3.55 andthey are also rumored to be 31 spline axles as well. I wuldnt doubt it the things are stupid heavy.
You can nix an explorer or ranger gearset as long as its an 8.8 and pay attention to the spline count too! if you find a donor box limo yank the wbole rear as well as the springs.
Choices from the trucks are 3.55,3.73, nd 4.10 ratios

[86VickyLX]

they do have 31 spline axles. If you notice the axle tubes in a limo rear are a larger diameter than a civillian vic. Also, can't run disc brakes with a limo rear unless you do 98+ rear brakes. Due to diffferences in the backing plates. It is rumored that the Limo rears are truck rears with the panther hardware welded on (spring perches, control arm brackets etc.)
