As some of you may or not know my t/a motor went BOOM and the block and all is busted. So with that being said a complete rebuild is needed and i'm gonna be doing a heads and cam while its out of the car.

I really like the 228R cam from TSP 228/228 .588/.588
their site doesnt say anything about needing a bigger stall other than custom tuning for A4 cars
*Does that mean I in fact DONT need a stall?

Next up,

Im looking for heads, but the entire heads and cam package needs to be no more than $2,000 minus gaskets. I'm thinking some ported LS6 heads would be nice, but do I need a double roller timing chain as well as double springs or will singles work along with a single roller timing chain?

My goal for this car is about 425ish rwhp and must pass NC emissions so no radical cams that wont idle and will flunk me for sure! Also driveability is a factor, this car needs to reamain as streetable as possible which means stock sized stall converter only!

Thanks for the help guys!

Have you looked at TSP's head/cam package, I think it under 2k

yea it is for the stage 1. I need some advice on if I need the dual springs or not though. My dad suggests I get the double roller timing chain with it, and im getting the ls6 ported oil pump for safety and peace of mind.

how much power do you think a set of ported LS6 headers and the 228R would make on an A4 car with almsot all bolt ons?

The CNC LS6 heads are a good option that won't break the bank. You can also add the competition valve job and dual springs if need be. Probably won't need the duals unless you decide to go over .600" lift though.

I used those heads with the 233/239 in my sig and made the numbers below. Had full bolt-ons too...

As far as chain, I used the LS2 chain. Plenty strong and works well.

Power estimate....eh, 410-425rwhp...just a guesstimate...

I dont plan on anything vboer the 228R's .588 lift so im guessing the comp single springs will do just fine.

410ish doesnt sound bad at all, hopefully a new block with diamond racing pistons I can hit the 425 and if not I'll jsut get those mahle 9cc dished pistons

Sounds like a good plan man. Good luck on getting that thing back together and on the road again!

oo **** almsot forgot, what about lifters?
does the cam package come with LS6 lifters or what?

marv

iTrader: (40)

Typically they don't come with lifters. But depending on mileage and the damage to the motor, I'd probably consider changing them.

Comp makes a nice OEM replacement (the 850s) and then there are the Morels (more $$$) and the Caddy racing lifters.

I run the Comp and have been happy with them, but a lot of folks seem to like the Caddy lifters as well.

Hope this helps.

will the replacements hold up ok with my heads/cam set up?

marv

iTrader: (40)

That's what I'm running with mine now (Comp 850s)...so far so good.

I've been happy with them, and I'd bet they'd work good for you also.

oh oh ok sorry misread it. mmk comp 850's it is then

maybe I can find a set of aftermarket rockers for cheap or just have nasty performance rebuild them

I don't know what NC emissions testing is like, but if that is a primary requirement, you're probably pushing it with 228/228, even on a 114.

Generally, you need -5 degrees overlap at .050 to pass. A 224/224 114 squeaks under that at -4 degrees
(224+224)/2 - (114*2) = 224 - 228 = -4

Conversely, the 228R on 114 is
(228+228)/2 - (114*2) = 228 - 228 = 0

and on 112
(228+228)/2 - (112*2) = 228 - 224 = 4

if not I'll slip a friend of mine a few bills and he will say he never heard a lope

With a smaller cam like the 228R, I would consider looking into the TSP stage 2.5 5.3L heads with 2.02 intake valves. They have a smaller runner that is more suited for smaller cubic inch motors. Have you considered any custom grinds. A lot of guys are running a 228/232 .588 .592 on a 110+2. This is what I am throwing in this spring. Custom grinds from TSP are the same price as the off the shelf cams. There are a couple of those setups in the dyno section running around 430 RWHP.

Jordan was saying the 5.3L heads will raise my compression, id like to keep it close to stock

Btw...man, I'd search on Comp 850s real quick and see if you can find a FS thread I saw a while back.

I think a guy was selling a set of Comps for ~$120. I think he only had 15 of them though, so you'd have to buy one to make a complete set. I think he said you could get them from Summitt or Comp for $20-30.

Either way it'd be a good deal and an easy way to get into a new set of lifters.

marv

Well, once again, this is what I'm running. Just bolted them to the car about 2 weeks ago.

Btw, the stock 5.3s from TSP unmilled will net you a 10.75 CR on a stock bottom end. They cleared my 233/239 fine btw so P to V shouldn't be a problem with the cam you're looking at.

im def gonna keep a look out in the for sale section for some things.

Concerning the 5.3L heads, how much higher of a compression would these give me over the ported ls6 heads, to be sure the 5.3 heads will give me some more power!

with that cam you are going to have a hard time getting the car to idle in gear with the stock stall. just my .02. i know money is a factor, but if you are like me i like to do it right the first time and not cut corners.
