Hey all,

I'm debating what cam I want to put into my stock 02 ws6. I don't want to hassle with replacing the springs every 20K miles so I thought about going with a hotcam or Z06 cam. It seems these cams are worth 15-30hp or so. However, if the tr224 cam is going to get me a lot more power than 15-30hp, I would probably consider the extra hassle of replacing the springs every 20K miles.

Remember, this is a stock car. The only mods in the future will be lid/filter, and cat-back exhaust (possibly true duals).

Having said that, what kind of gains would the tr224 give to a stock car?

Thanks,

Russ

You will most certainly want to replace the stock springs if youre going with the TR224 cam. It has a lift of around .560 if I remember correctly and thats just way too much for the stock springs. If you went with a set of Comp 918s you shouldnt have problems with them breaking with that cam.

However, if you plan on sticking with the stock heads, the TR224 probably isnt the best choice. Dont get me wrong, it will work, but you wont be able to use that cam to its fullest extent. I would go for something more along the lines of the TR220 or MTI's B1.

I don't know about this cam being a great deal better than the Hotcam.
Not talking from experience here, but there are folks on LS1 sites posting that there was little to no gain in dyno HP going from HC to 224.
Not saying it is true, but I am checking it further due to these claims, you may too...
Just to keep you an informed consumer.
Good luck
Dave

That's why I was thinking the ls6 cam or hotcam, as they are less aggressive and should not have any problems with broken springs.

</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">I've been trying to read up and see what gains people have been getting from the 2 different cams. I've been seeing ~380-390rwhp with all the bolt-ons and hotcam, and 390-399rwhp with all the bolt-ons and the tr224. That doesn't seem like much of a difference.

The specs of the cams are:
hotcam 219/228 .525/.525 @112lsa
tr224 224/224 .561/.561 @112lSA
2002 Z06 204/218 .551/.541 @117.5lsa

It would seem that the .525/.525 of the hotcam would be easier on the springs than the tr224(closer to the Z06 specs) Whatcha think?

Yeah, the HC is definately easier on parts.
Aggresiveness is what gives the TR it's slight edge though... What is your priority? Get a single digit hp increase for extra dough and wear OR go conservative and easier on your engine.
Different strokes for different folks.

Well, I really don't want to have to worry about spring failure and a bent pushrod or worse. I'm really wanting an install and forget it cam. Hopefully that's what the hotcam would be.

It all depends on what your looking for.
You can buy the HotCam kit that comes with ZO6 springs and the cam and not worry about a thing afterwards.
Or you can get Comp 918 springs/hardened pushrods and the TR224 cam and make great power (friend dynoed 399rwhp w/ TR224+bolt ons)
Personally I'm going with a B1: Specs are
221/221 dur@.050
.558/.558 lift
114lsa
This cam does require 918 springs, different pushrods, and only slight (if any) tuning.
I was going to go with the hotcam, but people in my club kept telling me it didnt have enough lift. Sure, people Florida and Texas have GREAT results with the HotCam, but they're also a lot closer to sea level than I am, which is another thing to look at.

I came very close to buying the Hot Cam. Because, like you, I was worried about breaking springs. And, the Hot Cam works very well w/ stock heads. But I decided I wouldn't put a cam in until I get heads. And, since my heads will have double springs, I went ahead and got a cam bigger than the 224. But if I was in your shoes, I'd get the hot cam.

here is something else about the 2 cams

as far as CA is concerned the hot cam will have no chance of passing. On the other hand the TR 224 114 LSA will just barely pass CA emmissions and they are the most strict it will be more stealthy too compared to the hot cam. Its alla bout what you are into though...can't go wrong either way

Boo Yeah

Are there no springs out there that can be used with the tr224 cam that won't need to be replaced??? When i decide between SC and TT, if i go sc i will need a cam to tide me over.

Granted, it barely passed, but it did pass. However, he was not in CA. Texas uses the ODBII scan for emissions testing and from what I understand, the hotcam will not throw any codes.

That's why I want a cam that I can forget about for now. Something that will give me good gains on stock heads and not cause any valvetrain issues. I guess I should also ask around to see what issues there have been with the tr224 cam as far as maintenance, and the same for the hotcam.

Thanks for all of your opinions so far guys.

Manley springs might be an even better choice....IMO

The more I look, the more I'm leaning towards REV double springs on any cam I buy.
