I was wondering if anyone has used a comp or crane cams turbo regrind with stock valvetrain. Im looking into buying one because my power drops off at like 5000. And i want the extra power. 2200 engine. and i searched

1) They don't make specified-app grinds.
2) There's no reason you can't use an aftermarket grind on the stock valvetrain, just keep the lift down.



fortune cookie say: better a delay than a disaster

does any one know the maximum lift that can be used with the stock valvetrain. valvetrain also has about 10,000 miles on it

It's about .480". It's posted in a bunch of threads. When I get to my computer I'll see if I still have the measurement file.

Im pretty sure you are right with the .480", but that is including the rocker arm's lift ratio. That would be a lobe lift of around .320" on the 95-97 2.2, or .311" on the 98+ 2200.

So notec what spec cam would u suggest for my setup. in my reg. im looking for power from at least 3000 to about 6300

put a 2.2 OHV cam in it.

I'll try to post more when I have a little free time tomorrow.

The timing notches are different.

Wait... You mean to tell me that the notches on the cam found in the '98+ LN2 are synched differently too? I thought it was just the crank synchs for the '97-later LN2s that were different.

Go beyond the "bolt-on".

The only cam swap you can do, I *think* is a 2200 in a 95 2.2 OHV, because there is no cam sensor in the 95? Something to that effect? But whats the point of it? The 2.2 OHV has a better cam.

No, IIRC there's a thread here that says not to.

Correct. Since it is not sequential injection, it does not need a timing notch. But like you said, the '95 cam is more aggressive in the first place.

Yes, but isn't the '96-up cam the same profile? With the notches for SMP/EFI? I'm pretty sure it is according to the history article I've read on the LN2. BTW, I still didn't get clarity on of the syncs are clocked differently compared to the '98-up cam. I no the profile is, but what about the notches already?!


Go beyond the "bolt-on".

The '92-'97 Hydraulic roller cams all ahd the same profile, but the '96 & '97 cams have an injector/pcm timing notch for the SFI as mentioned above. The timing notch as well as the profile were changed on the '98+ cams. The notch location change had something to do with the PCM & and crankshaft timing. Needless to say the prior people who first tried this change (I believe Event should know who they were), the car ran horrible. Besides, the diference between the cams is miniscule, I doubt anyone would see any noticible difference.

I have a 97 2.2 and a 2200 cam here. I am going to jerk the 2.2 cam out tomarrow and compare them and take pics and finally put this to rest. I have herd both ways but I am not sure myself but as of tomarrow we will know for sure.

You can test the location with the cam in the block, just pull the cam sensor and use a degree wheel and something to check the notch location (dial indicator on a magnetic base) and read the location of the notch on the degree wheel.

so the 95 cam will work on the 2200 or wont?

The PCM would go into batchfire mode (which it does on cold start-ups) and throw a CEL for no cam signal.

Okay, thanks Jack! I had suspicions about the cam synch timing being related to the crankshaft re-synch that occured in the later ('97-up) years.


Go beyond the "bolt-on".

So does a 2200 cam exist in the aftermarket for stock valve train? Another question is what about changing rocker arm ratio? I have an all motor 2001 and i just want to make it better. I have most bolt-ons already and i just want more power.

What is the stock rocker arm ratio?

1.5 from the information that i have

So i could just swap out for some higher ratio rockers and be ok. If not what do i need to do as far as machining.

I thought the 2200 was 1.54 and the 2.2 was 1.6?

I am looking for a cam profile I will be turbo and I want to rev to around 7000. Also would the stock springs be able to rev that high.

well if the higher the revs the more possibility for valve float so i would say no, currently though there are no springs that will fit without machining the spring seat some but we are waiting for Scarab to cut up the LN2 head and confirm we can. Secondly the rocker ratio is 1.54 from the specs that i have.

here is the link to the rocker that you can run on the LN2, using 1.6 rocker will give you a little more valve lift and more power:
