ok..sooooo. cooler weather is coming and i want to build my engine again..rite now check my signature for current mods..what im asking and trying to figure out is, whats the best way to setup my intake system and what tuner should i get.? heres my plans, i currently have a 80mm proflow tuned mafs and 24lb injectors. i wanna install those with a 75mm plenum and Tbody and then get a tuner and have a tune made for my car..i looked at blueoval and they look to have exactly what i need but 500 seems alot, id need the tunes and tuner plus the 75mm intake parts..what im asking is, should i run thr 24's with the stock mafs when i get it tuned or the 80mm proflow or get a lightnine or should i just dithc the proflow and 24's and stick with my 19's and get say a 80mm lightnine mafs? should i get 75mm or 78mm BBK 2in1 ? and when it comes to setting up an intake system wouldnt i want it to be largest at its end and gradually get smaller as it gets to the intake ports, becuase if it were sized wrong wouldnt the airflow be decreased by changes in volume of space going from large small large small( for example, nice big cone filter to a 68mm mafs to a 75mm plenum to a 75mmish manifold oninto small npi heads? like say a 80mm mafs to a 80mm tube to a 75 or 78mm Tbody and plenum on into my ported and polished typhoon manifold on into my bullshit npi heads where it will get restricted untill i do ported PI heads or just 32V swap...lets chit chat and figure out the best setup so i dont waste time and money, again..plus then i will be selling my old dowman Pi manifold, my 5.4Tbody anb new style plenum and im hoping to sell my current superchips tuner to start the fund for the cause..

[OptionalStang]

someone has to have some input here...i just took off my plenum spacer, 5.4 Tbody and plenum and put back on the stockers and i will be returning my tune back to stock also ..and lol i can feel the slowerness of it, exp in the 45mph+ range..but i took it off as part of a package ive put together to sell..

[sharkbait]

All of those intake parts are a waste.

Your heads dont flow shit and your cams dont flow shit.
Your not going to get any power from your different throttle body setups lol

Its a waste of money to dump anything into a npi setup

also you only need 19 # injectors. Until your pushing over 300rwhp na you wont have an issue. At this point i dont think your near 200hp na yet

[OptionalStang]

my car is rated 205 at the wheels stock i thought..i have PI cams,ported typhoon mani,exhaust..it ran faster with my 70mm setup and stuff that it does now with the stock Tbody and stuff..and also i gained a 0-60 when i ran my 24lb's and 80mm..but id rather just sell them and build my intake and fuel sytem to spec, plus then i can have it all tuned in..how come i see alot of stang owners run 78mm Tbody's and stuff on stock pi heads and cams...i know my npi dont flow as well as PI but with all thats built around them im shur i can get some good results out of them..dont get me wrong,id love a PI head swap but i dont have the know hows,place or tools..plus if i were to do PI heads id rather just sell everything i have and do a 32V swap..my goal is do everything around these npi heads and maby someday do ported Pi heads or sell off this engine and 32V swap..ut your thinking i wont get any gains doing a 75mm Tbody,plenum and a 80mm mafs even running on my 19's? i dont see how my stock could be better than that, even now it seems thats my inatke system isnt breating as much as it would like to..

and the onlything PI are my heads..my manifold is better than the PI and i have PI cams, are PI cams shit ?

[sharkbait]

they run a bbk 78mm throttle body and plenum combo. Its a single piece and works great.

Also your car is rated 205 at the motor from the factory.

Heres the deal. Lets say you have a pipe that is 20mm
it flows 300cfm

Now lets say we take a 80mm pipe and stick it onfront of the 20 and stick a 80mm pipe behind the 20mm.

It may be 80mm at the front now but its still only going to flow what the narrowest point flows (your heads).

You keep talking about buildin your fuel system. You dont need to. Put a 255 in the tank and call it a day for now.

If i were you i would do this. Get a BBK 78mm throttle body. Leave your stock maf and injectors in. Leave the pi intake and cams on it. Then just hit it with some nitrous or just boost it. There is no power to be had with a na npi headed car.

Also pi cams are just a stock cam from a newer model car. So its really not that amazing. If i were you i would throw a set of stage 2 cams in it. Something a little more aggressive. You may have to change out the springs but atleast you'll have something sort of fast.

Also your manifold. As i said. Your heads are the bottle neck right now. You may have a "better then pi" intake but if your heads flow stock pi flow then whats the good?

Yea heads may be a good investment for you aswell man. A set of MHS heads would make that thing rip.

Hell with a set of MHS heads + cams (2400 ish) BBK throttle body, your manifold, your 24s and your 80mm maf. You could pull off a 300rwhp combo easy. Maybe 320rwhp.

id love todo something like that but you gotta consider my spending limit..im hoping to have 500 or so from some sales and maby drop another 2-300 cash tops..theres not alot i can do with under 1k..i wish i could boost it for that..but its not possible.if i had 2k id just go get the npi svo sc kit, one on Clist brand new rote now it has even the belts injectors and all, even the tuner..but thats still 1000 over my budget even tho its a great deal..and why not build around these npi with what i have and then port them? would that be a good idea?

You cant port the heads without taking them off. If your taking them off theres no point to not just upgrade to pi.

Its all about savings. I dont make that much either man and iv been there. You just save your pennys and eventually you'll be able to afford it. If you really want it fast right now. Just throw some spray on it.

but dont ported npi heads outflow both pi and ported pi..? plus then it wouldnt cost anything other than time and me gaining experiance.I wouldnt do it alone believe that! so your saying i leave my intake and fuel system as it is and do what with sayyy 600$? keep in mind i dont have a garage anymore, not alot of tools and noone around by me with the know hows or who know anything about 4.6's noneless fords..i want my car to be fast but at the sametime a DD, and i want it consistantly fast..nitrous will come someday down the road maby,i looked into it for while and its not what i wanna do rite now with my car..

[sharkbait]

No ported pi head vastly outflow PI and ported non pi heads.

NPI is really a waste of time. Period.

Buy a nitrous kit with the money. If you dead set on not saving up then thats the way to go. Also your not "building" your intake and fuel system. Its were it needs to be right now. You dont need any fuel system work because you dont make any power.

Alot porting heads isnt something thats just free and takes time. IF you dont know exactly what your doing you can serioulsy destroy the heads. Its not like you just grind away and make it bigger.

[MustGT98allday]

yes. if you want more power now then grab some used pi heads, clean em up, get some nice stage 2 cams with springs and drop it all in with your current intake and maf and injectors just like shark said. youll be alot faster and it shouldnt cost that much. heads can be has for around 250. then cams and springs another 800 ish. you can find all sorts of deals out there so it could be cheaper. but thats a good way to go

[sharkbait]

my buddy is selling hi tech stage 2s for 400

[OptionalStang]

hmmm.....thats an idea but ille have to find soemone who can help befor id commit to that but i like that idea..

[MustGT98allday]

its really not that hard. just research and read and read the procedures and follow the steps. doing engine work always scares people but trust me once you do it and fire it up youll sit there and say wow. that wasnt bad. Unless of course you are careless and dont be careful and take your time.

[drakkhen20]

man, i would agree though about npi heads. i bought a Shaun Hyland book on how to rebuild a 4.6-5.4l mod motors and how to tune ECU books. Read a crap load and researched a many years. Mr. Hyland is the freakin king of mod motors and he has benchflowed and dynoed the diffrence with npi and pi heads. the whole reason why ford came out with the PI heads is because they researched it and developed a newer higher flowing head that they could mass produce. hyland found in his test that npi heads exaust flow stalls at .300 of lift. the intake runners are designed too small and the shape was all wrong. he goes into explaining in an anology that npi heads are like giving a athlete a straw and telling him he must breathe through this while running a marathon. hands down npi are crap no matter how you want to modified them or what kinda cams and air products. npi heads have a limit period on hp gains. PI heads gives you some room for expanding, but they suffer the same. they have limits also. aftermarket heads already are modded to a point to the limits that thier designed. the cold hard truth about it is you wanna go faster, your going to pay. all this part swapping your doing is a waste of time for yourself with npi heads. 32v motors are popular for their easy power gains because of their design being that they have better flow by default because of four vavles. you can find a lincon mk8 with a 32v in it but those suffer too from poorly designed heads because they designed those heads to be less aggresive for the type of car they were put in and the intake is designed to be more effecient with an automatic, so to go down that route youd still have to buy new heads for that aggressive hp gain. so really youd best listen to some of these guys as to saving your money and buy what you want and be happy instead of playing with what little money you have and feel like you gained nothing. buy a pi or do the pi swap and boost it how ever you can if your looking for constant power. 4.6ls love to be boosted man. even if you had a npi motor you could still buy a Kenne belle and gain 150-250 hp gain.

[OptionalStang]

i do have an automatic.thats why the 32V swap has been on my mind..im going to take your guys advice and get some Pi heads and go from there..then i can be PI heads,typhoon mani, and Pi cams..aka 2002 status.theres some ported gasket matched PI heads forsale by me with manifolds, vavlve covers and all for under 200$ ima talk to the guy to see if the valves are in them and all that..is there anything i should be weary of or look for? im unfamiliar with Pi heads noneless ported PI..

[Tang Stang]

I feel like we've discussed this multiple times already.

If you're looking for the best "bang for the buck", quit messing around with the intake/injectors/MAF. Gears, a TC with a higher stall, and a good tune will make a BIG change in your car.

[OptionalStang]

i see you have 373's is ur stang an auto? ive been considering 3;73's when i do do my gears..

[Tang Stang]

Yes, my '04 GT is an auto. It has 3.73's from the previous owner, which works well for my daily commute (84 miles each day, mostly 70MPH speed limits, and I typically run at least 10MPH over). I had 3.73's in my XR7 for a few months before switching to 4.10's, which made a big improvement in ET's and still is completely tolerable on the highway. Just going from 3.73's and 275-wide street tires to 4.10's and 255-wide DR's knocked a full second off my ET's back when it was NA.
