Engine Combination idea [/align]
[hr]


I've been throwing in my head the idea of a particular engine. But I don't know what kind of prices I'd face or who to buy from or whether to buy in parts in long block or custom crate motor form.

Here is the combo
5.0 big bore block (aluminum of course) with slightly better then factory internals (nothing fancy it would stay NA) and have a 10.3:1 compression or so
FRPP Heads that fit the 96-98 GT because i've read over and over how they are better then PI With a cam thats better then the 99+ PI cam. Possible a comp or something that will deliver power across the ENTIRE band.

Finished with the FRPP intake or the FRPP intake Blower.

This would be fore street use of course.

My guess is the bb block would be around 4,000
Heads 1,700
Intake 2,2000 or blower 3,000
fuel injectors 800
cam 600
Total $ 9,100 to 9,900 bucks for the complete block.

All this for well NA
70 hp for head and intake (Ford advertised)
25 hp cam (streetable and power across the rpms)
50 hp big bore (From what i've read 50 hp is obtained from a car with lots of bolt on's)
215 factory hp
30 hp in bolt on's already
415 possible flywheel hp with no porting Maybe a bit higher with proper tune and compression bump up.

This sound about right to you guys and who would even build it? Sounds a bit to expensive for a fun weekend car.


My car already has
FRPP shorty headers
o/r x pipe with mils
SLP loud mouth cat back
K/N FIPK
Underdrive pullies
as far as the motor is concerned and I drained the memory on my cars computer to try and get it to relearn the new parts.[/align][/align][/align]So what do you guys think? Price about accurate?[/align]

I think all the old heads do is raise compression. Seems stupid to do all that work and have ****ty flowing heads. The PI swap gains like 40hp and its pretty much a hci swap. Heads being a big part of it. I would suggest going pi. And you cant believe any numbers that companies say.

Wait so you're saying that Ford is lying about 35 hp gain from head alone and 35 from intake alone? That alone is more then a PI swap. Anyone with knowlegde on 2v'sknows that the FRPP heads smoke the PI heads in performance.

pi heads are better. it sounds like your confusing some stuff. if you put pi heads on a stock 96-98 shortblock it will make a lil more power than a stock 99-04 pi motor because the 96-98 pistons have less dome thus raising the static compression when adding pi heads. and by the way i would suggest maybe a 9.5 compression piston if you decide to go with the blower.

Basically what your talking about doing is a forged shortblock with heads/cams/intake.

Your looking at somewhere around 320 to 340 WHP with a fully forged shortblock, higher compression, aftermarket cams(like a stage 2 or 3) and a aftermarket intake manifold. Thats around 391 flywheel horsepower, with a 15 percent drivetrain loss.

Which FRPP intake are you talking about? The only ones I am aware of for a 2v are the PI intakes? If so, your going to be closer to 320 WHP if your just running a PI setup.

By adding PI heads to a stock short block will result in 10.3:1 compression on a 96-98 GT.

Helpful links for you guys behind on SOHC heads.

Its not the heads on the 99-04 that make them better its the PI cam and intake. The heads just add compression.

Steeds sells the FRPP heads I'm talking about The heads alone keeping the stock npi cam are 35 hp more then on a stock 96-98. Add the FRPP intake which the Bullit intake in modeled after and you get another 35 hp. For a total of 70 hp.

PI heads for sale, notice they don't brag about a power increase. Because like the above article stated its the PI CAM and PI Intake that are the power difference for 96-98 GT to 99+.
http://www.steeda.com/products/ford_...inder_head.php

Notice at Livernois they sell the PI intake shaved with an adapter so the ports on the 98 tear drop match the 99+ square port design. And they promise 35rwhp. So lets see 35rwhp is like 42 fwhp. 42 + 225 = 267 hp. Which goes to show the 96-98 heads are not crap.

So lets get this straight, PI heads can only had 10 hp by compression alone; however, FRPP heads can add 35 hp. So with that being said FRPP > PI heads. And if flat top pistons went in a new short block then FRPP 35 hp + 10 hp to a 45 hp gain.

Factory FRPP heads flow at the intake around 205 cfm too which is a PI head with a stage 1 port and polish from most places so it takes a minor port job on PI heads to even match FRPP heads.

Why would I want to hold my self back with PI, when with FRPP Heads, Intake, and a street cam I can net 100 hp while keeping the factory compression and with no port work. I could get a short block with flat top pistons and gain 10 hp that I would have gotten from the PI swap for a total of 110 hp. Port and polish the FRPP for maybe another 50 hp making it 160 gain, and get a big bore short block for another 50 hp. 210 hp gain over my 215 not including my bolt on's. I'm not intirely sure the max hp you can gain from ported and polished FRPP heads but i'm sure its much nicer then ported and polished PI heads. But will leave it at 50 hp.
215 hp 96 GT
210 hp block (big bore, flat top pistons, FRPP heads ported way past 240 cfm's, FRPP intake, nice street cam)
35 hp in the mods I already have
460 hp 1996 Mustang GT, with a 15 loss to the wheels 391 rwhp.

So please don't toss PI is better at me. I'm not new in the Ford World, no offence.

I think he's talking about the ford racing svo heads for the 96-98, they flow better than stock pi heads and the svo intake has a roots blower setup. That would be the way to go I guess but I wouldnt get that much compression if you're planning on not forging the bottomend or boosting to much psi.

jpmustanggt

If you do it then you definetly need to go with a forged bottom end. If you don't you will regret it.

Right, the FRPP (used to be called svo parts) Intake is the intake the Bullit intake is based on. The intake is good for another 35 hp. Their is also a 96-98 GT intake blower at a min of 55 hp on a stock setup. I don't really like hte intake blower but love the intake. Its just a matter of saving money. Because is a $11 to 13k.

I've been debating a complete car upgrade.
11-13k motor na
3k in suspenion work
4k or less in body and paint work (needs new body panels)
2k wheels and tires
2.5k news transmission
Expensive project on a 96 GT but it could turn out great
$24,500 bucks
It would be like owning a supped up 96 GT that can run with say brand new tuner stangs for half the price. Most of those cars are 40k.

If you want High compression dude get a set of Patrioit stage II heads and those are PI heads with valve job and ported and polished. Those will out flow any garbage designed for the 96-98.
