I am new at mustangs i currently have a 1998 4.6L v8 mustang gt and i was wondering if this items are good to start my mustang experience with? and can you please give me a Yes or no and if no please explain!

-Pypes 409 Stainless Steel Violator Catback
-BBK Shorty Headers
-Steeda Cold Air Intake Kit
-Accufab 4.6L 2v 70mm Throttle Body & Plenum Combo

And i might get a SCT SF3 Power Flash Mustang Strategy Tuner

 

Forget about shorties and CAIs. You waste money for no power and in the case of shorties, you waste time for no power. Remove the CAI on your airbox and drop in a K&N and you have a $40 CAI. For headers, long tubes or don't bother.

 

Your car has the worst heads,intake setup they ever put on the 4.6L motor. So adding things to help it breather better will help a bit but really you need to either go with a power adder to make it faster or swap the heads and intake manifold with the parts from a 99-04 GT. But if you want to start out with some mods then a catback is always nice as while it doesn't add much you do get to hear your car which is very nice.

 

ok so is this better? and i have a question why is it a waste for CAI? is it the same thing as just changing the Air Filter?

-K&N Mustang Drop-In Replacement Air Filter
-BBK Ceramic Long Tube Headers
-Pypes 409 Stainless Steel Violator Catback
-Accufab 4.6L 2v 70mm Throttle Body & Plenum Combo

 

dude, what do you want out of the car??


if i were you, i'd start by swapping your non-PI heads and your intake with some less restrictive stuff.

with long tube headers, you'll need to replace the mid-pipe. to avoid any problems with fitmet, i'd stick with the same brands. you can get what ever cat-back you want. an exhaust system is mostly done for sound, however if you do it from the headers and back, you can see some gains, maybe about 30HP???

if you want to do something now, i recommend gears and a tuner. and then save for a blower.

as far as a CAI, just replace the filter.

 

I am tryng to go fast more hp/acceleration and im tryng to find out what parts do i need to get so i can do that.. u say getting long tube i will have to change the mid pipe can you please give me the name of this pipe?

 

its actually called a Midpipe.

lol

Im throwing my vote towards a PI setup. might be cheaper just to buy a lightly used 4.6lV8 out of a 99-04

Also, depending on yer budget, a supercharger is always great

another popular mod is swapping out the rear end gears with 4:10's.

 

a midpipe is the pipe that contains the catalytic converters. when you get longtube headers, you have to replace it. with shorties, you don't have to, but its pointless since the stock cats are pretty restrictive. midpipes come in either an h- or x-pipe formation for the V8 mustang. its how the flow is equallized, and each sounds different. best thing to do is go on to youtube to search for the different sounds for different set ups until you find one you are happy with.

like jack said, i'd go with a PI set up, or gears and a tuner.

 

A CAI is a waste of money since you spend $150 for the same gains that you would get by spending $40 on a K&N drop-in filter and removing the silencer. Also, the PI upgrade is advisable, and depending on the factors, can be cheaper than long tubes and is one of the best upgrades.

 

ok i see.. but what exactly is PI full word please i am new to this .. and i am not trying to buy another engine jack.. i just want to mod the one i already have on my mustang so you guys say i should go with the k&n drop in air filter the PI setup which i need more explanation on also a SCT tuner and how about the throttle bodys and Plenums? should i even look into buying them?

 

well, PI is for Performance Improvement (accurate name, but apretty dumb one imo)

basically the stock heads on the earlier 4.6l V8's did not allow as much air to flow through. The PI heads alone bolstered the HP up to 260 and around 200ftlbs of torque.

As for buying another engine, ive seen 99-04 4.6l V8,s with under 50k miles going for as low $1500

PI heads on the other hand, are about 900 for the set, then you need the Intake which is another 200 bucks.

This will give you about 35-40 hp gain, and it will also mean any future mods will alsop give you more bang for the buck.

However, this is something that you WILL need a mechanic to do, and from what i understand it is about 20 hours worth of work, even if the mechanic is quick, expect to end up coughing up about 15 hours of work, which will run another 800-1500 or even more depending on the shop pricing.

By the time it is all said and done you might be able to afford a supercharger instead and actually see gains worth it, upwards of 100hp gain

I dunno, i would look at supercharging instead of a PI install, or maybe even swap the engine out for a lower mile engine with PI heads. You can find 4.6l V8's on Ebay for about 1,500 with around 50k miles.

... so in my view, with the cost involved, you can pay for PI heads and install for 2,500 - 3000, or you can swap out with a lower mileage 4.6l engine that already has it done for what will probably be quite a bit less money in the end.

 

For performance i just reccommend a Tuner and 4:10 gearing.... best bang for the buck with exception of nitrous, which i wouldnt do unless i DID have an extra engine laying around

 

ok i did some research and i will do the PI swap but where do i get PI parts? what parts need PI?

 

The PI parts are the updated cylinder heads and intake manifold from 99-04 mustang GT's. They will bolt up in place of your stock heads and intake and give a great power boost.

 

contact my good friend, Joe Charles at Gene Evans Ford in Georgia and tell him you want the "PI head swap kit" and tell Joe, I sent 'ya

 

Will this fit my 98 mustang gt v8? u guys said 99-04 and these are 99+ parts so i am guessing they do?

-Professional Products Polished Typhoon Intake Manifold (99-04 4.6L 2V)
-Patriot Performance 4.6L/5.4L SOHC 2V Stage II Cylinder Heads (01-04 GT)
-Comp Cams Stage II Xtreme Energy XE270AH Camshafts (99-04 4.6L 2V)

 

Do not bother with the Typhoon intake its a piece of garbage. Stick with stock unless you wanna dump alot of money for a manifold like the Bullitt setup or Reihcard Racing or the P51 all of which are not worth the cost to install on a street car. A stock late 01-04 GT intake manifold will do you good.

Also those cars are a great N/A street strip cams.

 

Ditch the Patriot junk too. Go to an actual, reputable head porter, like Total Engine Airflow, Steen Racing, Fox Lake Racing, etc.

 

zman, is there a mustang specialty shop nearby where you live?? you can talk to them... i'm sure they've done a swap like this before.

 

I am not sure if mustang specialty but i am sure they have done work on them... i will ask them but do you have any idea how much would it run me for a PI swap?

also i installed the K&N air filter and took off the silencer and for some reason i do feel an increase in acceleration not sure about hp.

 

I would have a hard time believing it would be less than 800-1000, but i dunno.

 

I was in your boat with my '97 and it just made more sense to me to go straight to a 5.4 It all bolts in the same except the intake and the mid-pipe needs some tweaking. In the long run it'll cost more than just the PI swap but 49 more inches makes up for it IMHO. There's a sticky on the swap.

Yea! LOL! I love my 5.4l swap!

When I first drove my '96 I thought, this is a good running car...............,but man....is it a turd!!!

I built the 5.4l before I got the car and it was one month after purchase, the 5.4l was in

 

So you guys think i should do a 5.4L swap on my 4.6L? how does this work is it a whole another engine or just some parts of a 5.4L? and when this is done will my car be able to go faster and others mods should work better with it?

 

Since you asked this question, a 5.4 engine swap may be out of your league in terms of skill, unless you have cash to pay someone to do it for you. Not dissing you or anything but engine swaps are involved and you need to know your stuff if you are going to attempt it.

 

I'm thinking about doing the 5.4L DOHC Navi swap and while I'd vastly prefer to do the work myself, what do you think it would cost to have a professional get it in there? Sadly I'm stuck at the university possibly without access to a proper garage for a few more years so it may come down to that.

 

OK i see what you are saying... will this 5.4L swap run me more then 3k$? having someone to install it for me + the swap it self? if yes do u know a estimate of how much?

 

That I would not know. Figure at least 1-3 days of labor so it won't be cheap. For you, the best route is probably a PI head swap since it's cheap, boosts power a good bit (especially w/ ported PI heads), and is fairly easy to do.

 

It all depends on how far you go and how much you can find a motor for. I'd say you could probably do it for around 3k with a stock 5.4 and the HPS intake.. The hard part will be looking for a low miles 2V 5.4 that's not too expensive, you'll be better off with a '99-'01 since they have PI heads and the timing cover has the correct power steering bolt holes. The install is hard to judge too, if you pay a shop to do it, they might stick you for $1000-$1500. Its good to have friends that know how to turn a wrench.

 

Why go for the 2V when a 4V navigator engine isn't that much more expensive? Well, at least for the engine. I have not idea what the costs would be to have a shop drop it in. I don't suppose any of you who have done it can estimate what a shop would charge? Is $2500 a fair estimate?
