I'm sure there are others, like myself, who are up in the air whether to go NA or SC. Since there was a thread started to list parts/costs for members SC setups I thought doing the same thing for those members that went the NA path to list the same type of information. Would provide a good cross reference from a $$ perspective for those of us standing at the cross roads!!!

The maximum horsepower you can attain by rebuilding the short-block with high compression pistons, adding $3000 trick flow head and cams, etc. is around 330-350 rwhp.

A simple non-intercooled supercharger costing $2500-$3500 will get you there. People build na motor because it is their dream, not because it is cost effective.

[number1gt]

If you want serious NA power you'll want a stroker in my opinion with good heads and cams, I like the idea of a stroker 5.0

[number1gt]

There is a guy on here with a 5.0 stoker making 398

Go Turbo

Wanna get more power

[DickH]

I am probably going to have ~12-15k invested into an NA mod motor to likely end up somewhere at the bottom end of 500-600hp. You could easily do a turbo/supercharged setup to make that kind of power or more for half the price. If I were you I wouldn't even try to compare the two with a price, the price to do it NA is just an obstacle for the foolish who are too stubborn to go with boost.

On3's new FF Turbo Kit list $2100-2200 I believe, for $3000-3200 you can get everything you need. Their test car was bone-stock except for Flowmasters and made 441 whp through a 5-speed @ 10 psi. Great starter setup.

[DickH]

+1 to the forward facing turbo idea, good start that gives you plenty of room to grow. Just throw in a decent bottom end and make enough power for 2 cars.

At least you are str8 out and honest about that instead of candy coating or downplaying it!

[99GT35thLE]

I'm one of those stubborn guys that refuses to go with boost, I prefer my nitrous when I want more power.

I currently have spent about $10,000 on my new NA engine that will be spinning to 7500 RPM and it's not even complete yet. But that is buying every part, bolts, and sensors new. I have done a good amount of shopping around for the best price and finding some deals on new parts that were purchased but never installed.

If you go on Corral.net, you can find some good deals on the Trick Flow heads and used or new superchargers and turbo kits.

I just started on my na build. My heads are warped and there is like a two inch chunk missing on the block underneath the intake manifold from the cheap previous owner. More than likely I'll get the 4.75 MMR Shortblock and slap the Trick Flow Stage Two Top End Kit on it. I have a good bit of na parts sitting in my room too, and yes I will be spending too much for the HP gains, but its something different.
I have had a supercharged and turbo car, so now I want a built motor and may spray. Like mentioned, you can easily spend less and make more power if you go other ways, but its up to you and your budget.

[saxmanJJ]

N/A will cost more no doubt for the same amt of hp.

Advantages to N/A is it is alot simpler and lighter, and you don't have to worry as much about blowing up the motor (vs. boosted).

Those Boss 5.0 modular based 4v motors with a stroker crank (5.3 liters) and trickflow heads make north of 400rwhp.

On another note, it is easier to stay emissions compliant with a supercharger than trying to make big power N/A.

Could you give some information on your build. The absolute most I've seen posted on a 4.6 2v is low 400s (I think it was 428). If I remember correctly the motor had 13.8 compression ratio, trick flow heads, a carburator running E85 fuel and it spun up to 8000 rpms. I'd like to see what you are doing differently.

A supercharger running 10 psi with cams will get you 428 rwhp on an otherwise stock motor. A lot of people are buying used kits then add cams and they might have $5,000 at most in their motors.

[StangGT99]

I definitely want new cams. I'll be honest, I really enjoy that idle rumble. So if I want somewhere around 350 rwhp going SC is still the most cost effective route? Though I guess what I'm reading here is that for the same $$$ amount, to get to that rwhp, a SC will provide even more hp.

So if I went SC and added new cams that's all I would need to do to the stock engine? Thought I would also need new plenum, TB, and CAI.?

[86er]

its gonna cost, but If you want a real good base for a n/a engine you will need to big bore the block and stroke it, which takes it to the 5.3 range. You will want 11:1 compression might be able to get away with a little more, but depends on the gas in your area. You will want, no you will NEED a custom set of cams, an Edlebrock intake, and all the other bolt ons. You will need to spin it to make the power. 2v or 4v will determine what your final hp numbers are. But be prepared to spend 15k easily to do what I said above

Info. I have found and am upgrading to ford GT style heads, also have an FR500C intake on its way. Setback of the year is that I now intend on putting Darton MID sleeves in my 5.4 block (or dry a sleeved aluminum 5.4 for not much more) With a 3.71 piston and 4.165 stoke ill have an even 5.9L big bore. With something around 12:1ish compression, and aggressive cams for a 7-7.5k redline I better clear 500.

you going to have a fast or bs3 to rev it that high without spark blowout? and some big ass cams to keep making power that high

[slow02gt]

if you go just a 20 over motor, light h beam rods, good pistons,stock crank prepped, trickflow heads, mhs stage 3 tf na cams, a decent intake with the compression around 11:7 its an easy combo for 350+

[moneygreenstang]

400HP has been made on a raised compression (pump gas) 5.4 4v with Navigator Heads, Custom Cams, and the aussie boss intake
