Parts here... Any helpful tips for the install?

whr2206 · 04-13-2005

Hey all...

My cobra intake manifold and the 75mm TB that came with it arrived today.

Now... I've never messed with the throttle body or the Intake manifold... So are there any helpful tips you guys could give to make the installation go smoother? Also, excuse my ignorance... but what is TPS?

Hopefully I can get it installed this weekend and get back to you guys on how it went.

I've got my gears here waiting... Im just going around town getting estimates on how much the install will be... Should I just wait for the LCA's and get them both installed at the same time? I just heard that in order to install LCA's... you've got to unbolt a lot of things....

thanks a lot

The throttle body is straigh forward installation, so is the intake really. Just make sure you dont crack any of your vaccume hoses as they are probably pretty old, and may be brittle. If you installing a lower intake, dont use the front and rear cork gaskets, just run a THICK bead of Black RV gasket (the cork gaskets go all over the place when you put the intake down.
TPS= Throttle Position Sensor, just tells the computer how hard your hitting the gas. Should read .99, with your voltmeter (see tech article on tuning your engine on how to adjust your TPS)
I took my whole axle out to get my gears put in, then i just put all the arms in at the same time. Its not the easiest task, you just have to get some of the mounting holes to align. But if your gonna get it done at a shop, have them do it all at the same time. Or you can save some $ and get your hands dirty! go for it man.

Alright thanks...

Yeah I may just read up a bunch and try to install the gears myself... MAYBE.... It just bugs me that installation is more than the gears cost... Plus how am I ever going to become experienced in auto mechanics if I don't do it myself? Reading articles is one thing... but nothing beats hands on experience....

the hardest part about gears is trying to get everything aligned in the back, are you using the stock diff with just a new crown and pinion? or are u replacing the entire thing? if u are replacing the entire thing just look @ what new parts u have try to assemble it as much as possible on the bench and then put it in place, with the crown gears, what i recommend doing would be to put a puddy on it so that you can see how the gears line up and see if you have to shim it, there will be a wear pattern on the assembly puddy, do this all with the inspection cover off,

the tps should be @ .98volts,

and the upper lower intakes are easy, the upper has 2 bolts under the 5.0 HO plate, use a torques bit to take the plate off, there should be 6 bolts on the upper and 10 on the lower i think, the upper is a 1 day job... i pulled it off pulled my fuel rail and all my injectors had a spray pattern test done and had it all together again that night,

and yeah, tb, easy, 4 bolts... tps is on the top of the tb

I also got 4 of these Ford Racing Upper to Lower Gasket M-9486-A50... Do I put all 4 of these on at the same time or what? One of them looks like it has a tiny crack in it.... will this matter??

Well, the person sent brand new FR gaskets (still sealed but somehow one has a small crack hmm?) ... How much does Black RV cost?

cmandockdunk · 04-13-2005

i get my RV gasket from Autozone, it comes in a cheesecan like thing. costs $12.99 i think. If the crack in the gasket is all the way through, then dont use it. I ran a bead of the RV AND my gaskets just to make sure. Only reason not to use the front and rear gaskets is because they move all over the place when you set the intake down. (saw that on Hot Rod TV!! lol)
When i was saying do it yourself, i was talkin about the U/L control arms. I had my gears done and i got ripped off, but i dont think i coulda done them myself, espcially as one of my first mods. get the gears done, do the rest yourself! the experience will DEFINATLY help you! good luck boss

btw, its RTV, not RV, anyways, you can do the gears yourself, but if your not very experienced on working on rearends then i wouldnt suggest it considering if you dont shim it correctly then it will howl its ass off and then wear out the gears real quick and then you gotta pay more money just to replace them. but the lower control arms you can do on your own no problem, just put jack stands under the axle tubes to make sure the housing doesnt shift on you while you take them loose.
with the intake manifold. make sure you mark the distributor and rotor positions so that you put them back in the same place. make sure you get all of your vacuum lines matched up and make sure not to overtighten any bolts so that they dont snap on you!! intake manifold may take you a little while but its not hard to do.

whr2206 · 04-14-2005

Yeah one of the Ford Racing gaskets is cracked all the way through.... SO should I just use the other 3... and apply the RTV gasket... or just the RTV? It said on the FR gaskets that they may not be street legal in some states... But how can ford racing gaskets not make your car pass emissions? I dont get that....

I took a look at the intake and it doesnt really look that much bigger than stock (height wise)... But I'll still have to replace the struct brace bar? Thats another hundred dollars I certainly dont have... haha......

Is the 75mm t/b to big for his setup ?? I was told by alot of people that 70mm is the limit for alot of cars.

89stanger · 04-14-2005

don't bother taking your distributer shaft out, leave it in place, take the cap off, that's easy, i think it's just 2 clips on the sides, take the rotor off, just pull up, take the lower half of the cap off, i think that's just 2 or 4 screws, and leave the shaft in there, i have taken my intake off a few times, it doesen't really get in the way, not on my 89 @ least, i have no upper strut brace thou... i would say take the upper off, then unbolt the lower and disconnect everything, see if you can pull the lower without taking the distributer shaft out, if u can it will make it easier...

the tb, from what i know, going with the 70 rather than the 75 won't make a difference with the stock lower intakeif the lower flows more than the 70 mm tb then u will notice an increase in power, but if it flows less there will be no difference, keep in mind the od of the tb will be bigger so u are going to need a cai probibly... or a bigger intake tube

Don't do the gears yourself. You will need to press bearings on that you need a press for, and need a mic gauge to check for play in the gears. Also the shimming issue. As the previous guy said, you'll be hearing a whining in the back and then be back here.

I don't mean to be negative, but trust me, pay for the gears, but do the arms and all that on your own. Good luck, and you will love your new gears

Regards

I was going to bring that up, I think a 75mm is rather large. If you have a near stock car, I would not go over a 65mm.

Thats what I asked in an earlier thread. Most people just said to try it out...
The 75mm is port matched to the intake... does that matter? Or is it still too big? I would trade for a 65mm Ford Racing throttle body.....

I didn't really have an option though... he was selling it for $400 all together....

So should I just hold off on the installation until I trade for a 65mm and when I get my MAF?? It might be easier that way...

89stanger · 04-15-2005

just install it and try it out, if it doesen't work, then worry about it, u can always put ur stock tb on the after market intake, it will probibly still make more power than your current setup...
