Hmmm...

Your question thoroughly confuses me. Do you know, or do you not?

well i think i do know it will fit. just need to be 100% sure won't mess up anything

what would the gains be??

alsey_seven · Post by **alsey_seven** » Thu Jan 29, 2009 1:53 am

what i've been seeing and reading is a few horse power

cuz i am intersted in doing this....

The cam will 100% work, but I highly recommend using mag valve springs and retainers with the larger cam. A mag head swap would be more effective performance wise, due to larger exhaust ports that could make use of the more aggressive cam profile. The cam itself with no tuning is probably good for < 5hp/tq, if any at all.

dont you have to run also the safc thing since the car will not idle correctly?

Not with the R/T cam. Just the crane 14/more agressive valve overlap cams. The only SOHC cam that has overlap from the factory is the '95, and it is only 1/2 º.
With out any other mods, you will feel very little gain.
Remember the Magnum engines are only 18 more hp with all the supporting hardware, coupled with about 10% better gearing for motivation. (Factory stock)
So even with the supprting mods, without the 3.94 MTX, you will still be down roughly 10% at the wheels. Prolly not exact, but you get the idea.
Edit: with an ATX prolly more of a loss to the wheels.

I did it... thought it would be a great idea to just swap the cam. nothing... I feel that it was actually a little worse off than the stock cam. If you want the gains... you'll need to drop some serious $$$ on either head porting or the R/T head new header, intake porting and even then you're at a disadvantage due to the lower gear ratio's in the R/Ts and ACR's. Doing all that work DOES make a pretty significant increase over stock but lets face it, neon was not meant to be a strait line car.

what if you do magnum intake manifold , magnum header, and of course the magnum cams . would the cams be a gain then? cause i am wanting to do all of these so just wanna know also will have CAI, 60m tb, and UDP . sorry for the threadjack just figured its related

Basically, best case scenario you could gain 18hp if you swapped everything. Complete head, intake mani, exhaust mani, and PCM. And don't forget pistons; compression is a half point lower on your engine as well. The head is probably the most influential piece of hardware on the power gains. So if you only do part of that list, expect part of those gains. Without the head, PCM, and compression you might see a few hp/tq, but then again since you wont have timing or fuel settings tuned for the different cam, you may actually loose power and/or shift your powerband to an undesirable part of the rev range.

I've learned that the 2.0L engine, both standard and high output, is best left virtually stock. Mild/mid-grade mods are a waste of money per hp/tq gained. A wild build is a different story, but for anything short of that, spend your money elsewhere. If you want a faster car, try to reduce losses by adding a lighter crank pulley, high flow exhaust, high flow air filter/intake, lighter weight oil, low impedence ignition components, and last but not least, overall weight reduction.

First it is cam.

with the 60mm/Mag IM you should have a noticeable gain. Prolly not earthshattering but noticable. It will be a little more fun to drive.

That's how my cam swap was at first also. ('02 Mag) but it took almost 700 miles before something clicked, and then it started making a little more power. I even cleaned the horrendous casting flash from the exhaust ports, and opened them up a little under the valves (nothing major). But it took almost two tanks of gas for the PCM to do what ever it took/needed to do. Which cam did you use?

Redline5th · Post by **Redline5th** » Fri Jan 30, 2009 9:41 am

Mine came out of an 01/02(can't remember) ACR. I debated on going to the Mag IM but was advised against it as the Mag IM has the second stage butterfly and was told that I wouldn't be able to get it to work on my non RT. I didn't research it too much so I built around what I had.

I left that cam in there for about 3000 miles, swapped it in with an oil change, swapped it out with the next... and it never seemed to "wake up". Maybe I expected more or something.

I ended up with porting, headers and a cam that's s'posed to be just a little bit more mild than the RT's. I ended up spending more $$ getting the suspension where I wanted it... it'll never tear up the drags, but Auto X maybe

i have a r/t cam, i did notice some gains in acceleration. but if u do swap da cam i highly recommend the valves springs and retainers.

You don't need the mag retainers, just use your stockers. Titanium retainers are a waste of ALOT of $. Get mag or crane springs.

The retainers come with the Magnum springs if you are buying them new. They are dirt cheap compared to the crane springs. About $85 for a complete set MSRP. The Crane basic springs (158830-16) $148.99 Crane titanium retaners/springs(CRN-903-2003) $315.95 Summit Racing

so what will the results be with a 01 mag cam, obx r header , mpx 60mm tb, aem cai, and udp, with a 3spd atx

hybrid-Srt2001 · Post by **hybrid-Srt2001** » Wed Mar 25, 2009 2:45 pm

ditch the atx if you want any gain

Post by **occasional demons** » Wed Mar 25, 2009 5:29 pm

Or if you keep the ATX, there is always a higher stall converter, and RMVB

But you have to weight the cost of ATX upgrade against the cost of swapping an MTX. The parts for a 2000 mtx may be difficult to find depending on what's in your local JY. It might be easier to go with an '01-'05 MTX hydraulic clutch set up.
There are a few threads on this issue if you search.

hybrid-Srt2001 · Post by **hybrid-Srt2001** » Wed Mar 25, 2009 7:55 pm

for what it costs to upgrade an atx you could mtx swap. For a 2000 with the cable trans you can use a 1gn trans etc

The fun part is finding the '00 pedal assy.

Exactly. The other half is installing it. Who needs to drive the damn thing when you can put it together.
