Ls1 in cobra

[Quadcammer]

are those motors emissions legal over here?

Im not sure what the aussie requirements are.

I know birdman has the aussie intake and is happy with it, but im not sure about the cams.

Mr. XJR fella, there is no point in arguing further. You think the Ford 4.6 Dohc is a better engine than an LS1. I disagree for several reasons which I've made abundantly clear.

You will never change my mind, and I won't change yours. All the other bullshit is useless.

Continue to think that you "won" our little argument. I will do the same.

Cheers.

Quadcammer ftw! on this one....

For the record I also think the LT5 is a better engine than the LSX series. :fart:

The Boss 315 is Euro V compliant which is the most current Euro emissions standard, but that standard seems to be a little more lax than Tier II Bin 5.

I have the Aussie stuff here.

You don't know how many times I've considered scoring a dirt-cheap '96 GT and buying your 5.4 kit.

Wow what happened in here?

Quadcammer and I became good friends. :lol:

The 2v motor has potential, the 4v has even more, albeit it's not a '03/'04 Cobra motor, it's still a great motor!

 

[birdman941]

The Aussies love their Boss motors, for sure.
Basically the Boss motors are 5.4 short block with 03-04
Cobra/Mach/Marauder heads, Aussie intake, single blade
75mm TB (Except the 315 which is dual blade),
fly by wire, shorty/mid length headers.
The FPV site states they have "R" heads, but it is NOT true.
The 290/302/315 have higher compression (domed pistons),
more cam and a different calibration than the Boss 260.
The closest comparison to anything we have stateside is the 260.
Basically that is a Navi short block with 03-04 heads.
The few aside from myself who have driven mine (Stock Navi long block)
with Boss intake, LT's and dualblade TB,
are stunned by the response and torque it has.
You gotta drive it to believe it.
Once I get the motor from Al, it will obviously be a lot stronger.
Even in stock configuration, it will slaughter my Mach 1.
Here is a side by side comnparison of the 2000 "R" lower
and the Aussie Boss 290 lower: (Aussie on the left)

wow this got messy, my last post was yesterday like in page 2 lol, to Quadcammer... isn't the LS6 just a H/I on the LS1???
to the OP is good you'll keep your car with the FORD engine, i was against this cause is a COBRA if it was a regular GT or a 6ser go ahead,


LS1-4.6DOHC great engines

o and for the great defenders of the 4.6 can you give me a response to my mechanics question??? (i hate when he does it!!)

WHY DO COMPANIES DO A KMEMBER TO FORD APPLICATIONS WITH LS1 SWAP AND NOT A CHEVY KMEMBER FOR ANY FORD ENGINE?????

lmao

Nearly everything is different between them, rotating assembly, block, cam, heads, etc...

Because people have been swapping "cheap" Chevy small blocks into Fords for about 50 years now.

I for one do not think the Chevy 350 is a better engine than the 351W at all, but that doesn't stop people from plopping the 350 into fox bodies.

 

[Zep]

Put a GM POS in a Cobra?&*@!#$%! That's heresy!

Agreed. I'd take a 351 over a sbc anyday. Hec look how nasty a lil 347 can be.

 

[Quadcammer]

whether or not you like the idea of the swap, to call an LSX a pos is simply ignorant.

 

[cobravenom99]

ok, how about can someone just answer some of my questions i posted bac on like pg. 6 or 7.

you say you want to build an engine from the ground, why not bolt on your current one? Full Exhaust, Pulleys, CAI, SRA & GEARS and a dyno tune mid to low 12s thats a very respectable N/A time anywhere

more like high 11's...my last 01, which still did not have ported intake, headers, pullies, or any weight reduction just ran 12.49 @ 111 with a shitty 1.85 60'...you go full bolt on and tune and drag wheels and you're looking at 11.7-11.8...

 

[cobraracer46]

If he wants to state that the 00 Cobra R makes 375rwhp, then Im fine with that. In fact, I'll concede that point. The 00 R makes 375rwhp on average.

Its still a rare engine with heads and especially an intake that are nearly unobtainium, and given that this kids budget doesn't allow for anything this fancy, its sort of a moot point.

Well, the Cobra R intake might be difficult to get, but the latest update on the 2000 Cobra R cylinder heads: the Ford GT units are readily available as fully loaded heads right from Ford Racing performance parts dealers. The Ford GT 5.4 aluminum block is also easy to score and I would assume that getting your hands on one of the Aussie intakes so you can build a replica 2000 R engine would not be too difficult.

:nonono:

Yea id have to agree, looking at buying a new edge cobra and have owned a ls1 but I wouldnt swap one for a 4 valve....for a number of reasons

The Aussie intake fits ""C" or 03-04 heads.
It will bolt to Navi heads, but the ports do not match.
It will NOT fit FGT/Shelby/00"R' heads.
FPV says that the heads are "R" heads, but they are not.
I have several Aussie intakes here as part of the Mustang install kit.


Also, just so you are all aware,
Kar Kraft is selling a "Boss 290" engine according to them.
It is not even close to a Boss 290 spec, more like a Boss 260.
Wrong compression, wrong cams, etc.
Don't be fooled or burned.
