4.6l 4v cobra motor

I posted things relative to the topic, and when the topic progressed so did my posts.... thats what we call conversation.

and hows that 1986 240sx of yours holdin up, still imaginary as always?

This thread has entered into the class Ford vs Chevy rivalry

[dj56x]

it's supposed to say 89... i know its entered into that class and to me it doesnt really matter. i've had both, but my camaro had an lt1 and almost 180k miles which was really slow.

[urcaptnspeaking]

haha I figured. I was just busting your balls.

[urcaptnspeaking]

oh and lt's are torquey motors but run out of top end power, still a good base for a performance motor though.

My 4.6 cobra motor took the worst beating i will ever give a motor. The transmission sucked tho.

[Ls1pwr]

either way they still get the same kind of power, and sound cooler... besides this thread wasnt even about which is better.

sorry but this is not true at all. they do not make the same kind of power and cant even begin to compare to an ls1 without boost or nitrous. they may sound better but thats just a ricer comment and really is in the eye of the beholder.

so the 4.6 is heavier, bigger (dimensionally), sounds better, less horsepower and potential (Naturally Aspirated).

ALL BARK.

the ls1 is lighter, smaller, lower center of gravity, more horsepower everywhere and basically limitless potential.

ALL BITE.

I know this thread is old but today, I just got done installing a dynoing a dohc 4.6 ford supercharged motor and it made 800hp.

It's a 2003 cobra with a Lincoln Mark 8 aluminum block, bigger blower, cams, forged bottom end stuff and it makes good hp.

With bigger injectors and a stock computer with a tune, it runs fine.

Plenty of bite and it still has a pretty docile idle.

That said.....I never want to work on another one because of the complexity of it's accessories and it is just too damn wide.

I'm installing a 1800hp version in our shop ford GT twin turbo tomorrow and it is proving to be tons more of a pain the arse.

We'll see if it takes the standing mile record this november in florida.

The amazing thing is its cool to see this modular ford swap being done by one of our members. I don't know how the headers will fit yet, but man its tight.

After all this debate one was started..... gotta love determination.

[JSDEVILDOG29]

most older hot rods all use chevy 5.7 liters. Regardless of the bodys make it's hard to deny a ls. And most of them use the tuned port injection system out of the late 80s camaros firebirds and vettes. It is the most manufactured engine ever and I doubt any other motor can come close to the longevity of it. I'm not a ford hater I love fox body stangs but year after year the ls motors dominate fords v8s.

editman im not even going to get into this toilet of a thread lol

hhhhhheeeeyyyy That thing got a hemi???? Im staying out of this... ?? What about the lt1 motors from 95-99 tahoes would that fit in a 240? If so who wants to help me with the swap...

[killernoodle]

I'm not staying out of this, I'm going ALL IN

PS: I'm shooting for at least 600 whp. All bark what?

its a waste of time, and would ruin the way the car handles. adding 200+ lbs to the car is a big no no unless ur drag racing the car. plus there are bolt in kits for the ls1.

exactly and now wait a minute, check out December 2009's Import Tuner.They featured two Silvias, one built for drift the other for drag.

Blew my effing mind seeing both cars with the original engine and putting out numbers like.....The drag Silvia: 1,400hp at 11,000 RPM with 750 ft-lb of torque at 8,600 RPM.The drift Silvia: put out 568hp at 6,800 RPM with 420 ft-lb of torque at 6,200 RPM.

I don't see a point in putting a completely different engine in a car that you can make all sorts of power while keeping the car's foreign roots.

[OutToWinPAHC]

It makes it fun, and easier to get something most inline 4's struggle with.... Which is torque. If I made 750ft lbs of torque at 1400 horsepower I would never tell anyone I made 1400HP if I was only making almost half that number in torque, I would be embarrassed. Torque is what moves the car, horsepower is a calculation based off the torque. Although horsepower is a real unit of measurement, dyno's don't measure horsepower. The calculate that number in a reference form based on torque, time, rate, rpm, drum weight and speed.

Now to make a 750ft lbs from an inline 4 is huge, an awesome feat, and pretty bad a**. But it probably cost close to 100K to make that power when for 1/4 the cost from a V8 will make that or more. Even just on spray alone at that, no boost needed.

But at the end of the day it's all the owners decision to put whatever they want under the hood. But when going for huge numbers 500-1000ft lbs or just makes sense to use a L6 or V8.

Someone asked me a question at the meet this year, "why would you put a V8 into a 240 when you can make the same power from an SR" (275-300 RWHP stock form) And my answer was because after the swap is done I bolt on and tune for 600HP, where you will need to speed a lot more and engineer for that power. The he said "well I have seen SR's make 700HP" and I said "Yeah and I know people who make 1500-2000 from an LS series".

It's all about why, not the roots.

[Nissan409]

Yeah god GM sucks, i mean creating the 350 v8..... what a horrible motor! right? And who ever said the 4.6 DOHC isnt a power plant... are you f***ing retarded?

Lol 1400 hp from a SR? 11,000 rpms from an SR?

What are you smoking?

And a 600hp SR is not only not streetable, but not reliable. Hell, a 200hp SR is barely reliable

Quick question: how many motors can you name that can and have achieved 1000 hp ON STOCK INTERNALS?

I'm pretty sure you'll only find Modular Fords on that list (Terminators, Lightnings, GTs) and then the veyron lol.

He's smoking that TRUTH serum..... Google Mazworx drag Silvia.... I agree on the reliability point though. Dont forget the 2JZ on that list.... And tell me any of those Modular Fords that are reliable at that power on stock internals.... Nothing is!
