im looking to get a different intake on my 98 lsc. i know alot of people put the cobra intake on our cars with good gains in performance, but i also red that the gen one intake has better flow and performance than the cobra and wanted to know if its possible to put a gen 1 intake on a gen two motor, and if it is which would be a better intake the cobra or gen 1 in terms of performance.
 
somebody asked the same question a few weeks back, i'm pretty sure the answer was yes you can but, it is not worth the trouble.

I would think the cobra one is better. Otherwise Gen II owners would not be dumping $300 or more for a Cobra intake when a Gen I intake can be had for less than $100.

Other than the intake, there is not much cost really. If you cap of the EGR I read you can use the stock rails of the Mark. The harness should not be a prob. Overall its a 1 hour job. Quite a few have done it. There is a thread on another forum. Two guys are about to do this it looks, they both have the intake. PM me if you want the link, lots of very helpful info!
 
i would like to take a look at that link because doing an intake swap is something i plan on doing in the near future and need all the info i can get :cool:

I couldn't tell you which one is better, but I do know you can put a Gen 1 intake on a Gen 2 engine. The major problem will be all the electronics that will be moving to a different location.

I swapped a Gen2 engine into my Gen 1 and was able to use all my stock parts, but its gonna be different when you want to swap intakes.
 
i suppose ill just be going with the cobra intake then being as there is so much more information on it and so many people have done it it seems like the much easier route of the two.
 
I'll put my Gen1 intake against a stock Cobra intake as far as flow, especially with headers. But having said that, moving the throttle body to the Gen1 position on a Gen2 would be a hassle for various reasons.
 
Unported vs. unported, the Gen. 1 intake manifold will keep up and possibly outflow the Cobra manifold, if only due to the increased runner volume. Bear in mind that flow is flow, and does not take into account how well the intake is tuned for your specific setup. Take the Cobra manifold to be ported and have the runners shortened, and you have a real high-RPM screamer that outflows all but the dedicated racing manifolds (which are 3x the price).

One thing to note about leaving the stock Mark fuel rails on there: you will not have access to the schrader valve on the fuel rails, meaning you cannot check your fuel pressure, ever. The valve gets hidden underneath the "ear" at the front driver side of the manifold where the IAC valve mounts up.

What if you ported and polished a gen 1 intake? Would it flow as well or better than the ported Cobra intake? Is porting and polishing the Gen 1 intake worth the time and money?
 
Port and polishing an intake is like getting headers. On a stock setup adding these has PROVEN to gain next to nothing. But if it makes you feel good, you can do it.

That makes no sense, the IAC is on the passenger side by the TB, no?
 
Ok... lets talk basics... WTF is the point in putting in 5 hours of labor and 500-700 to "swap" intakes? The cobra one gets you 10 maybe 20hp at the most... a gen 1- gen2 swap? No documented #s for that.

A chip would be a better investment when it comes to both money and time and would probably provide same results at the track. Combine that with a better flowing exhaust and you're ahead of the game and you have a better sounding/shifting/accelerating car. For a similar amount of money.

Doesn't Geno still sell those? The cobra around the Lincoln ... hot stuff back in the day lol.

I wish we had some dyno numbers, but I *thought* the Cobra intake resulted in better torque at the low end of the RPM.

I think Dave (sleeper) had some #s on the cobra intake b4 and after. The gains were slight. I am sure there were a few others... (Jeremi for ex, but I haven't seen #s posted) but this isn't a very simple change the air filter type job. That intake doesn't quite fit the mark VIII right and it doesn't clear a Gen 1 hood. and requires some modifications of the throttle cable and other things on the gen 2....

Also it is illegal for SMOG in cali... as well as pretty much anything else you can do your car :p
 
Not a good comparison, but I picked up some hp and some much needed tq going from my stock gen 2 intake to a 96-98 cobra intake. But like I say, not a take one intake off, and put on another - dyno comparison. I have a laundry list of things that were changed between the two dyno pulls.

My research convinced me that from the guys that did what I did and switched from the gen 2 intake to the cobra intake, not a single person went backwards in hp and tq - either na or boosted, doing this mod. 100% positive results that I found, as small as they may seem. :)
 
Yep no one denying the fact that it adds power... how much is the real question... where it is a good first mod is an even better question... I would think that for later supercharged apps this would help out a bit more so than on a N/A mark. Then again Burbank is still running the Gen 2 intake and he is well into the 11s.

Sleeper (Dave) has the following mods on his car
the cobra intake, long tube headers, custom mandrel bent exhaust with magnaflow mufflers, 3200 RPM stall torque converter, 4.10 gears, SCT chip
He put down 250RWHP. I don't remember his baseline.... If we assume 220hp which is pretty good for a gen 2 he picked up 30RWHP with that combination of mods...
