Talked to brian @ TEA today, And he talked me into S1.5's. They come with 2.02 intake valves, 1.57 exhaust valves, double valve springs, CNC'ed etc.... Any of you out there heard any good about them, have them yourself? I need to learn more about them, because come monday, my heads, and a money will be placed. Good HP/TQ gains. This Heads package will be mated with the TR230 cam, and/ or one of TEA's custom grinds.
Please people give me some input here. I want a lopey, awesome car when im done Thanks everyone..
Also, if you were to guess, what would be my HP/TQ after this combo?

I have a set of the Stage 1.5 / 5.3L TEA heads. The 2.02" intake valves are Ferrea. The 1.55" exhaust valves are stock GM. You will be getting brand new heads. The chambers have some material removed to unshroud the valves. After all is said and done, this gives a 63cc chamber. They will mill the heads .003" (3 thousands) just to insure straightness. This will get you between 10.7 - 10.8 to 1 compression ratio. Using pump gas, I don't think you need anymore CR. Of course, they can be milled to achieve better than 11.0 to 1 CR, but I wouldn't go that high.

Mine have Comp Cams 918 springs and stock GM retainers. The springs are set at a 1.77" installed height which will give a 135-140 LB. valve seat pressure.

Below are the flow numbers from the "Flow Pro":
Take good look at the exhaust flow:

@ .200” lift 138 / 121

@ .300” lift 201 / 160

@ .400” lift 251 / 230

@ .500” lift 284 / 260

@ .550” lift 295 / 265

@ .600” lift 300 / 270

The car runs very strong, but has not been on the dyno yet. Cam is a fairly mild TR220.

BTW, I have ZERO oil consuption since installing the cam, heads, headers and intake. (34,000 mile 98 A4)

Brian @ TEA said, since im running nitrous, that my S1.5's will have 1.57 exhaust valves. Will this benifit anything?

Tin Indian

Maybe I'm missing something here. Are you getting 5.7L or 5.3L heads? My above post is strickly about Stage 1.5 TEA 5.3L heads.

2.02" / 1.57" valves are normally associated with Stage 2 heads.

Personally, this whole "Stage" deal is all BS. There is no standardization between suppliers as far as Stage this or Stage that. Like I said... Stage is all Mumbo Jumbo!

Ron,

I'm talking about 5.3 heads. Since Im running nitrous, he'll install 1.57 valves, and still go for 1470+core.

AMS had tried to get there LS1Edit hooked up to it but failed to connect. They did one short run on the rollers, but terminated when it was evident that they could not tune the car. It did 375 rwhp (unlocked converter) at that time. Your right..

Since then, the PCM was re-flashed at a local dealership. Then it was mailed to Thunder for tuning. Geoff was able to access the PCM. It now needs to go on the dyno to get the numbers. Just have not had time, however, there is a dyno down in Birmingham that I will be going to soon. The car is running much stronger now that Thunder did some magic to the PCM. Hope to dyno in the 390-395 range with a locked converter. That would be pretty good with a 220 cam and headers with cats (no cutout)

BTW, I had a friend ATAP the car, but he thinks its too lean at WOT (averages .880 O2 sensor voltage and about 3 degree knock retard) Still the timing is showing 26 degrees throughout the run. ATAP says its shifting at 6,000. That needs to be increased to 6,200. I am going to send Geoff the ATAP data files and see what he thinks. The computer may need to go back to him for more tweeking. I may hold out on dynoing it till everything is right in the PCM.

Well, I went out to Steel dragstrip today.

As I said, the car shifts at 6,000 revs (too low)

Ran a 12.30 ET with cats through the muff.

It was a hot day in the southland. The [corrected] was 12.14 @ 113.22

MPH is low, but the car is an A4 and shifting at 6,000. The PCM is going back to Thunder to have the shifts raised to 6,200 or 6,300. That should get me about another tenth and a half. Maybe the car will run in the very high 11s. Remember, it's got a nice mannerly TR220 cam with cats. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Nice runs today Ron! Look for that spreadsheet with your atap numbers in the morning. Back to the guys original question. You will see some serious HP from the TR230 cam and the TEA heads, the steetablity of it may leave something to be desired though. I think that Ron and I both are happy members of the "baby cam" club.

gomer...

Well, your car ran very very well considering you have stock heads. Wait till you put on some good heads. That car is going to be a rocket.

Lots of fun down at the Steele track considering how hot is was yesterday.

I just got my rig on the road a couple of weeks ago.5.3s with a 224/.581 cam.
It runs REAL good <img border="0" alt="[evil]" title="" src="graemlins/gr_devil.gif" /> <img border="0" alt="[burn out]" title="" src="graemlins/gr_burnout.gif" />

It's not tuned yet - showing NO knock retard on Mobil 93, Ave. LTFTs around 4.0, 800 rpm idle with nice little lope - IAC counts are still a little high; however, I havn't drilled the TB yet.
I've had a couple of idle relearn issues - but it's only stalled once when hot on a rapid decel <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" /> .

The real test is today when my wife drives it as a commuter car.

Go with TEA, they stand behind their work with honor. <img border="0" alt="[USA]" title="" src="graemlins/patriot.gif" />
