2000 302 performace parts

[dubbedexpo]

i need/want a few performance parts for my expo..
1. underdrive pulleys
2. bigger throttly body
3. throttle body spacer
4. bigger MAS
i already have chip, intake,and exhaust.. i just want some more power... does anyone know where i can get these parts for a 2000 explorer 5.0 302???? thank you very much

 

[jimbo74]

try www.summitracing.com www.jegs.com www.truckperformance.com www.explorerexpress.com
if i recall correctly, the throttle body spacer doesnt really do much in means of horsepower.... the other stuff is more worthwhile

1-underdrive pulleys. no one makes any, and none will adapt. sorry.

2-bigger throttle body- no one makes one, but 88-93 stang throttle body can be adapted easily. your Explorer throttle body is a 65mm, and will be all you ever need unless you plan on seeing over 375hp N/A. dont waste your $$$ here.

3-throttle body spacer-dont do anything. if you have to have some kind of spacer, get a 3/8" phenolic spacer to go between the upper and lower intake. it will work alot better than the throttle body spacer

4-bigger MAS- go ProM 80mm all the way. try www.speedfreak.cc he is a sponsor here, and will be glad to hook you up.

 

[RealXP8]

yup, you don't need the throttle body, 70mm is worthless without lots of hp. Underdrive pullies would be a waste even if they had em. The 5-8 hp they give on a mustang causes more trouble than good. I tried the phenolic on my 5.0 mustang, to me it's another worthless mod. I like the mass air idea, they are commonly worth about .2 in the quarter. The 80mm is alot of money, so you might want to check out the 75mm it cost's half the amount but definetely stay with pro m, all the others are junk.

James, what's the actual size on the explorer mass air meter , 55mm?

 

[tmsoko]

The explorer MAF is 70mm - should be sufficient for N/A explorer engine with stock heads and hot end exhaust. If you really want to go to a larger one, you can get a 80mm Cobra MAF for cheat, as most Cobra mustang guys are buying the 90mm Lightning MAF. With these components, it is hard to beat the quality of the OEM parts. I have seen the 80mm as low as $50!

 

[james t]

tmsoko is right- its 70mm. but, it's still a bit restrictive. definatly something i would throw in the trash.

BTW- dubbedexpo- if you have friends who know how, your biggest N/A power adder right now would be a cam. the stock explorer cam is very "Briggs and Stratton" like, and even the stock 5 liter Mustang cam is bigger than the explo's. an E303 is a fairly small cam, but will dominate over the stocker. definatly worth the $$$.

 

[RealXP8]

James,
How bout just changing the rockers to 1.72's the cam is alot of work. I have the e cam in my stang and that was alot of work with the motor out.

i really can't see the benefit in an 80mm mass air though, at least in his case, 70 is a fair size, 4 bills for a pro m is alot. 5.0 mustangs with much more power rarely exceed 77mm for street use.

I haven't heard of the 80mm cobra switch though, Do either of you guys really believe it works?

 

[james t]

dont know about the switch, but i suggested the 80mm just so he wouldnt have to buy one again just in case. who knows, one day he may wanna blower. buy it once, i always say.

yes, you could put 1.7s on the stock cam, but ever hear that saying "you cant polish a turd"? it may help a bit, but nowere near as much as a cam swap.

look at it this way, expo5.0 has the same year truck as me, with the same mods as me. with intake, exhaust, fixed throttle cable, and a 75 shot of nitrous, i ran a best of 15.25. him- with intake, exhaust, fixed throttle cable, and an E cam instead of nitrous he ran a best of 15.3-something. that really says alot about the stock X cam. i realize there are alot of variables that could have affected both our runs, but im fairly certain with an E cam and no nitrous we would be about dead even.

 

[RealXP8]

James, i do like the cam swap, but as i said, it's a ton of work. might as well port and polish the heads while your at it. He also might have a hot motor. Cam alone isn't worth much. Maybe 10-15 hp. certainly not enough to equal 75. 5.0's are incredibly inconsistant. His x was probably fast to begin with, did he have any baseline runs? 20-30 hp differences are common.

 

[dubbedexpo]

well i only want the throttly body spacer so i can tap my nitrous in it...

also do they make headers for a 2000??? i need that also...

 

[RealXP8]

I don't think you need the spacer for the nitrous, but don't quote me on that. They definitely make the headers because i have them, i just don't know where to get them now.

 

[dubbedexpo]

well i have the mac air intake and i don't want to tap into the tube so i thought if i got an throttle body spacer i could tap into that and not the tube.. what do yall think??? oh and if u could try to remember where u got your headers i would appricate it....

ive been told that I have a hot motor. alot of guys here dont believe that i did my avatar pic without the nitrous. also, i ran a 15.9 with exhaust/intake, and i think expo ran about the same before his cam.

i gotta disagree with you on the 10-15 hp difference a cam makes. i have seen dyno runs to prove otherwise, and this was going from the slightly better stock 'stang cam. remember, FoMoCo tried to put an RV cam in a Cobra motor (the Explorer) and it really didnt work all that well. the stock xplo cam flat out sucks. although i havent ever done a cam swap on an explorer, i would imagine it wouldnt be much different than on a stang. not really that hard. proly take about a day to do.

dubbed- i hate to tell ya, but you're gonna have an impossible time finding headers. the only ones available were the FordRacing ones for a 96, and you could use those IF you have an EGR bung welded on them. however, they were discontinued a while back and no one has them anymore. no one else makes any, and none will even come close to adapting. either get really lucky and find someone with the FMS headers, or spend big $$$ having some custom made.

 

[expo5.0]

i might have a hot motor, but the cam also made an incredible difference to me. keep in mind that the stock explorer cam pretty much gives up at 4,000 rpms and i am now revving the e cam up to 5,200 or so. i don't have directly before and directly after quarter mile times, but if a stock awd runs 16.4 it must have made a pretty good difference for me (thats the normally thrown around number--- as suggested i could have been a little hotter factory) i believe the e-cam is a 30-35 hp increase over the stock cam.

if i were going to mod a 00 5.0 i would go this route---

throttle cable mod (lol)
exhaust
intake
baumann
mas
cam
port and polish
high flow cats and headers
charger
nox

and of course attempt to keep the computer tuning as up to date with the mods as possible, just order a chip when you feel like you are done modding for a while.

If it were me I would make a phone call to Keith Craft, or Bennett Racing, or DSS. I have had great results in having them build and tune and answer many questions. I always thought that FRPP was good stuff, and for the most part some(very little) is. If you think about it there is so many aftermarket parts out there and companies that spend more money than you can think of on parts for the 5.0 ,4.6, 5.4, powerstroke, V10. I would not waste my money $169.00 on a cam, $280 on rockers, that are off the shelf crap that is over priced just because it has FORD written on it. You can make your 5.0 what ever you want it to be, it has been around longer than most of us and people who say you cannot mod you motor have little or no idea how. Most companies if you call them and talk to them hte will make what you want and like in my case it only cost me a little more $ not hundreds more.

Just my .02

Cams give well over 10-15hp, I've seen 5.0 Mustangs recieve 30rwhp or more on the dyno with just a cam swap, Ford stock cams pretty much suck, Explorers take the cake for crappy cams.

The e303 cam alone will drop an Explorers 1/4 mile time by almost a second alone, 10-15hp is not going to do that which translates into what, 3rwhp . I met a kid last year who had a 5.0 Mounty with bolt-on's, chip, shift-kit ect ect., he swapped to the e303 cam and that dropped his 1/4 mile time down to about 14.7, I think he only had a few more mods then expo5.0 but I still thought expo5.0 should have ran a little faster. I made a post somewhere (I think in the speed section on a Cobra thread) about going for a ride in the Mounty and couldn't believe how fast the cam made it.

Ford's cams that are in the sohc and dohc modular engines however are pretty damn good, thats why you'll see almost everyone leave the stock cam alone. However, obviously theres always better like SHM cams

My friends n/a 01' Cobra has bolt on's along with an SHM (Sean Hyland Motorsports) cams. The SHM cams with the grind they made him for the dohc engine are amazing, it'll pull quite a bit past redline very fast and strongly. SHM is expensive, but worth it, I bet they could grind some awsome cams for Explorers.

You can get the headers at summitracing.com I just got some last month. You will have to get the egr fitting welded on and a hole drilled (i got mine done at local exhaust shop). The other thing you could do is use the headers and get a performance chip w/ egr delete.

The cam swap is one of the best things to do. It really makes a big difference, alot more then 10-15hp. The swap is the same as it would be on a stang, but you will probably need the motor pulled (well worth it).

In the long run a cam swap would be most benifical as it would respond alot better to other performance mods you make. The stock pos will hold your motor back.

no need to pull the motor. just the radiator, grill, and a few accessories.

 

[RealXP8]

First off, i checked about the cobra meter swap, my sources say that it shouldn't be done, the sensor is calibrated for the meter size as well as the injectors.

Guys, the cam is not real beneficial without heads. It is a proven fact in 5.0's. Read any mustang magazine or call any ford speed shop. If what your suggesting is true of the performance gains, every mustang with an e cam is a 12 second car. I'm not saying it doesn't work, it just doesn't do that much without good heads. The e cam is not a great cam, if your going to pull the cam it you should put some better in. And i speak as someone with an e cam in my car. The only reasons i didn't use a different one, where: 1: i had the cam already 2: you can't go bigger if you have 1.72 rockers because of clearance issues. 3:I needed to get the car done immediately.

 

[SaleenEXP]

I was talking about the e303 cam in an Explorer b/c it's the most popular and good all-around, their are better cams (even better if you have a custom ground cam) that will make more power, but the e303 cam provides power throughout the whole rpm range in an Explorer (especially down low) where as others start making more power in the mid-range and up.

I think jamest has a Comp cam lying around, just begging to be installed thats a little more radical then the e303.

The kid I met last year had a shift-kit, exhaust, intake, and chip and maybe some other things and was running mid to high 15's with those mods in his 2wd Mounty.

With only swapping in the e-303 cam, he dropped his 1/4 mile time down to 14.7, thats basically a full second just by switching the cam. 10-15hp is not going to do that, 10-15rwhp won't even do that espeically in an SUV. He's also 19yrs old and installed it himself by going through the front end as jamest said, he's actually rebuilding an 89' fox body thats gonna be sick, very skilled for his age.
