I am anout to put a cam in my 98 A4 ta. I am going to keep the stock stall and I am going to change to 3.42 gears. Here are my requirements:
1.I want to know that I have a cam. I want there to be a lope.
2.The car must remain a daily driver(I drive it every day)
With the cam that you suggest tell me if I will need to replace springs and if it will need tuning. Thanks for all the help guys.

 

it depends...do u wanna past smog...if u don't care a nice cam is the 231/237 598/595 cam from tsp..or if thats to big and u wanna go smaller for smog reasons....tr224 will be a nice choice...it depends on if u wanna pass smog or not..they are both daily drivers...i have the 231/237...its a great cam...with that cam u need crane dual springs...great setup...tps is having a special on cams right now..u should take a look...to pass smog don't go over 224...o and with your a4...u need tuning with either one...both cams will give u a great lopey sound...the 231/237 give it a bit more lope...sounds great...good luck

 

why wont the 231/237 pass smog tests? Yes I have to pass tx smog.

 

231/237 won't even come close to passing smog. Too much duration. It will be misfiring or "loping" at idle far too much to pass smog.

BTW, ditch the descreened and ported MAF if you're going to do this. All you've done is screw up a calibrated sensor.

As far as big/small cam goes, I'm not getting into the argument. Most know my opinion.

 

are you sure the tr224 will pass smog? and what lsa? 112 or 114

 

tr224 might pass smog. You'll need to be on a 114, maybe 115 or so to pass. Biggest thing is excellent tuning.

 

i agree with denzss...a big part is tuning...224 with a 114 and good tuning will pass...with cats of course...but to be safer go with a 115 lsa...not as much power...but don't think it will hurt...also not to much of a lopey sound

 

115 vs 114 is basically irrelevant in the power department. As long as you're a 114+, it should pass with GOOD tuning. Keep in mind that most people and shops are not good tuners. Satisfactory, but not what I would call good. Tuning for power and emissions is a specialized field.

 

where would i get good tuning?

 

Man if I were you I'd ditch the factory converter and get a stall converter. Gonna be more noticeable than a cam. I'd say go with a 220 cam if your gonna keep the factory converter. Maybe even a LS6 cam setup.

 

Hey I had a lunati cam in mind. Let me know what yall think about this. 55003LUN. Go to www.lunaticams.com and look that up. Now that I think about it, when I get my car inspected they don't put anything in my tailpipes. All they do is plug something into the plug under the steering wheel. Is that still the smog test? The main thing I want in this cam besides power is a lope at idle. Thanks for all the help.

 

anymore help guys? I could really use the help.

 

I wouldn't go any bigger than 224/224 on a 114 LSA if you need
to pass the sniffer. This with tuning will easily pass. You'll
definately wanna upgrade to a bigger converter as well. For a
daily driver, I'd say 3200-3800 tops. There are people driving on
4200+, but I personally wouldn't.

 

With that cam will there be a good lope at idle?

 

Look into TSP's new 225 cam as well.

 

wouldnt a MTI b1 cam be perfect 4 him ??

 

what are the specs of the b1 cam? I can't find it on their website

 

spend the extra few hundred dollars and get a converter otherwise you'll likely be slower than stock with most of the cams I've seen recommended...honestly with 2.73 gears it would take you forever to get into a 231/237's powerband 4000rpms+...even the smaller 224 cams dont make peak tq till 4500-5000rpms so in my personal opinion get the vert & the cam at the same time otherwise you'll be looking at the same timeslips as you did before if not worse depending on how big you actually go. If you just want the lope pull one of your plug wires

 

I passed emissions testing last time with a TR224 114 cam and burned out cats! I did the tune myself with LS1edit.

 

I think they discontiued the b1; this was one of the older cams. Just order a C1 cam on 114 if you want somthing like that. The B1 was a 221/221 on 114 LSA. Lift was .558/.558.
