[Monster stang 97]

Hello everyone my name is Paul and I just bought a 97 black GT 5-speed and its all stock execpt for Short throw(very short throw), K&N drop in and steeda pedels(adds 25hp.....j/k lol) I'm adding Flow 40's and orh, 96-98 cobra wheels, K&N CAI and 4.10 gears for bolt-ons. ok my real queastion is for BIG power I was thinkin either doing a P.I. head swap with maybe VT stage 1 cams and bullitt intake or Allen supercharger(or KB if i can afford it) and run between 6-9psi(more like 9 psi) and call it a day with the charger. so which route would u guys go and why? which will provide more power and be better for a street only car? btw ,my car has 108,700 miles on her. help me out guys! thanx!

Personally I would say build a whole new motor and then swap them in! You have high milage and that is the reason I say that! Personally I would start from sratch and work your way to the Blower! Everything sounds good and if you stay with your stock bottom end I would say go closer to 6 bcause of the mileage. Personally I like centri blowers better, so I would go with an S trim vortec instead but what ever floats your boat! And hell while your doing your head swap put in some different valve springs and then use stage 2 blower cams!

[Monster stang 97]

i would do the whole "i'm building my motor up" but i'll only enough to do a head and intake swap for sure OR a supercharger with a lil more money. I like roots and twin screws the best....love that whine and instant power on tap....don't wanna rev the piss outta her to make good power. but like my ?'s asks which route would u guys go? H/C/I or just roots blower?(street car only!)

[Casper98GT]

Ok heres the deal. Great thinking in my own opinion. But youre NPI motor will be pushing 10.5:1 compression ratio after the PI swap. I would yank youre NPI heads and work them. They respond well to that. The PI swap also involves replacing the intake...youre roots style will replace the intake anyways. So heres what im thinking.

PI head swap..nope.

Work youre NPI heads. Get them to flow better.

Then put a set of either stage one NPI cams, for blower applications. OR THrow in some cheap 75 dollar PI cams. Not knowing what youre money situation im sure you have some if youre thinking about all of this.

Next you can do a KB but like you said its expensive. Go with the Allen i like this s/c as well. So now you have cams, good flowing heads, and a allen s/.c. Throw on some other bolt ons and youre all set.

108k miles.... if its maint. well....then you can get 200 easy out of it. But keep the boost to 8 or so.

Hope it helps.

96-98 cobra wheels

Almost forgot... 96 and 97 have the same wheels. 98 have diferent spoked wheels.

[Monster stang 97]

ok thats good advice but i was gonna do one or the other not both.....just too much money with doing head work then cams then a $3400 supercharger. I'm gonna have bout $3500-$3700 to work with. don't want ungodly power just either a nice H/C/I street stang or a nice allen supercharged street stang with bout 8 psi and maaayyybbbeee p.i. cams. ...i'm on a budget as well and just looking for a nice set-up for the streets(i know it won't be the fastest but it will suprise people) i also wanna know what will make more power outta my 97? Allen at 8psi(with all the bolt-ons) or p.i heads VT stage 1 cams and bullitt intake(again with all the bolt-ons) JUST BETWEEN THESE TWO SET-UPS PLEASE

[Casper98GT]

S/C will gain more. That s/c will get rid of youre crappy intake too. Just get that S/c and then some cheap PI cams. And you'll be happy.

[Monster stang 97]

sweet thanx man! so p.i. cams and allen supercharger at 8...mmmaaayyyybe 9psi. hmmm i better do a compression test be4 any kind of boost. where do i go to get one done at? and will my 4.10s be ok for taht or am i gonna have to step down to 3.73's or something like that?


btw the motor is in really good shape from what I and my best friend(who knows a great deal on 5.0's and mod motors) it has had up to date maintance all its life. at least from what the records say

[Monster stang 97]

Ok i think since my car has alot of miles I'll do the Allen 6psi kit with P.I. cams . I'm hopeing to hit 275ish rwhp. would that be possible with all the bolt-ons and what not? also i'm doing a 4.10 gear should be a fun street car but mght be too much gear...what do u guys think?

[Monster stang 97]

????? anyone ?????

[tlr96]

i wouldnt see why you couldnt 275rwhp. with the 4:10's probably be a pretty fun street car.

[MustangMatt96GT]

4.10s are what I am going to put in mine! The 275 will take some head work with different cams and a PI intake and then all the bolt ons you can think of, but without swapping heads it is possible!

And Casper I dont know who told me that, but it makes since and I should have chaught it because of how a Compression Ratio works, and thanks for setting me straight!

I have a 96gt 5 speed with 108K also. I was thinking of the same thing and talking to the guys at my local Mustang shop. The guy told me, in his exp. with non pi cars the 1st thing he would do is get rid of the non p.i. heads as a starting point. That is with my situation and the condition of my car. I got lucky and bought it from a woman that baby'd it all of it's life and had every piece of paper in regards to the maintinence on it, so we know my engine is perfect (just a little carbon build up on the back sides of the valves).
After the p.i. heads and intake is on then we can later look at more power mods as far as superchargers. The non p.i. heads just don't flow enough air.

[Monster stang 97]

hmmmm i also took into consideration of droping a 96-01 cobra motor in and build from there. it might be cheaper in the long run and it'll be a high to mid 13sec car to start with. just a thought....sound good???

[MustangMatt96GT]

4V>2V and the 4V will benefit you much more and probably be cheaper if you want a 10 second car, but I want the challenge of getting large numbers from a 2V so thats why my plans are to stay with a 2V.

Again , someone gave you bad information. The heads flow nearly the same, P.I flow a little more in the low to mid lift areas and the npi flow better from .450-.540" (max lift the npi can run without some work). I won't get started about heads again, SORRY...LOL

[Richs96]

SO what is the big deal with the heads then? Is it because there are no intakes available for the non PI heads so everyone thinks there is a huge difference in air flow. I know the casting for the intake ports are different, but that is nothing a little silicone won't take care of.

[Monster stang 97]

I think i might just go P.I. swap with bullet intake and stage 1 cams and call it aday. i'll still make as much power as a stock 99-01 cobra so i'll be pretty happy. i think it will cost less in the end and be more reliable then being blown at 110k miles ya heard

[ujslost]

since when did 108k miles become high milage? Not since the 70s!

[TOWNCAR92]

yea
