TR227/224, TR224, or TR230/224 Well, Christmas is coming and I'm looking for a nice cam for my car 
.
I want some power, but I want to keep good driveability and be able to pass NJ emissions easily.
Originally I was looking at the TR224, but when I was on TR's site, the reverse split cams drew my attention. The TR230/224 makes nice power, I was thinking this might be good for me on a 114 lsa. The TR227/224 is already on the 114 lsa and should make some pretty nice power. I'll admit, I don't know much about cams (trying to read up about them, my head's been spinning trying to take it all in
). I'd love to hear some experiences with any of these cams.

seriously look at MTI's X1..it's 230/227 .591/.571 112 or 114...the car pulls hard all over the place and w/the XE-R it makes great power all over.
i have the 112LS in my A4 and with a bit of tuning from Jayson and some piddling with my TB hole it idles like a dream...cold start/hot start...ac on or off...doesn't matter.
TR's cams are badass too...but I am just throwing another peice of madness ur way.

I think getting thru emissions easily will also depend on the type of test.
~230 ish on a 114 to 115 LSA with "emissions" program & cats can probably be sweaked by the sniffer test.
If it's an OBD-II scan the the 230 will be about as easy as a 224, IF the LS1 edit stuff is done correctly and rear O2 are left ON and sim'd.
Of course if they see LT's they can fail you anyway regardless of the rest of the stuff passing if they want too.
I have no idea about roller testing.

The three are actually quite similar. From what I've seen (I'm not claiming to have first hand experience), the differences between the TR227 and TR224 are, on a stock headed car, negligable. The TR230 may make 10-15 more RWHP than the 227 or 224, but that extra power is made above 6,000 RPM. Furthermore, the torque curve is identical for all three cams, so it's HIGHLY unlikely you'll "feel" any difference between them.
I was in the same situation as you and have decided on the TR224. It's easier on springs, will be easier to get through emissions, will be more driveable before the tune, and makes almost as much power as the bigger TR230. As I said, I don't think one would feel any difference between the three.
In the end, you can't go wrong no matter which one you choose.

I have had all three of those cams with stock heads. They all have their pros/cons, just like anything else.
For what you are trying to do with the car, the TR224/114 would be my choice. It is Thunder's best all around cam in my opinion for a street driven car. My car went 11.50@118 (1.7 60') with stock heads, 4:30s, and this cam.
The TR227/224 is also an excellent cam. The car did feel slighltly faster with it over the TR224 and the idle quality was about the same. I never did get a chance to run my car with this cam, as we wanted to experiment more with the reverse splits. About 3 weeks later, I swapped to the TR230.
The TR230 showed the best results at the track (as expected). My car was setup to run this cam though, with the longtube headers, 4:30/4.56 gears, etc. The idle was quite a bit more choppy than the TR224 and the TR227. The really liked this cam and I used it for the longest time out of the three (a little over a year). With the 4.56s and stock heads, the car went 11.25@121, 1.55 60'. After I went through the shortblock with new rings/bearings (still stock pistons/rods), I added GTP stage 2 5.3l heads. This allowed me to run 10.88@125.5 (1.50 60').
Here is a graph of all three cams in my car with stock heads. Nothing was changed other than the cam (same tuning,etc):

. come smog time im thinking about swapping out my 230 for a 224 on the 112. i dont think my 230 will pass, im gonna try it though. if it doesnt they the 224 112 or 114 will go in, plus it looks like the power loss will be minimal

I'm very happy with my 224/581/112. After I get it tuned and dynoed on 11/14, I will post here.
This is the best "all around" cam if there is one...

My goal is with et streets and short belt to go under 11.5 with just the cam on a great track day and to run consistent high 11's.
