ms3 on 243 heads ported + ls6 intake Hi, Im from Mexico and now Im upgrading my camaro...
I recently bought a L33 heads (243 casting) and im gonna ported here in mexico with Chester (monterrey) and put a ls6 intake.
But I was thinking to change my 222/224 cam for a MS3.. what would you do? keep my old cam or improve with ms3cam.. also a friend sell here a mexico a Trex 110lsa but i think its huge for an A4 and city ?
any help wanted?
thanks...
can I buy here a MS3 cam and send to mexico or its impossible? just asking..)

You could possibly run into clearance issues with an MS3, especially if they don't have stock chambers. You could call Texas Speed and ask, maybe to no avail. You could order it and risk having to flycut. You could keep the same cam (kinda small). Or you could go in-between. Call them with all your build info, they're great guys and will help you as much as they can.
The set up will work fine as long as you keep 64CC chambers and mill the heads ever so slightly no more than .005.
Secondly PTV still needs to be checked no matter what any one says.
I have a costume grind that is closer to the MS4 in my C5 A4, I will say this you need to have a very good tuner tie the whole package together. If you are doing a budget build the LS6 intake is great if you can afford it I would do the FAST 90, along with a 90MM throttle body. The more air you get into that N/A build the better it's going to run.
Do not be disappointed when you dyno your car and it gives you horrible numbers the A4 is known for drive train parasitism but it will perform on the track like no other.

My opinion.. You have no where near enough converter, you need a minimum of 4000+. You don't have enough gear, you need a 4.10. You don't have a good enough intake, ms3 is a top end screamer and your ls6 won't breath enough to take full advantage of it. Tune is up in the air for now I guess.
If I were you I would take out your cam and move up to a 230/232ish 112LSA .600 or something around that size. You could move up to a 3600-4000 converter which would match perfectly.. You could keep your gears along with your intake still being able to somewhat keep up. The heads should be fine.
Ms3/Ms4 cams are max effort cams. Meaning you have to be able to buy the biggest/highest flowing parts to take advantage of them. If you can't, you can make a car just as fast as one of them with a MUCH smaller cam. I have proved this over and over to some of my Ms4 car buddies. I use to own a ms4 car, now I own a 226 cam car.

I have pissed off 3 MS4 cam owners with my current car.. My ms4 car would have **** on their cars but it was set up properly..
A properly set up car is much better than a donkey dick improperly set up car, don't forget that OP. Cam is NOT the main ingredient in making a car quick.

The car I'm racing mods are...
ls6 block
PRC stg 1 ls6 heads
YANK 3600
373s
Ms4
full exhaust
my mods (pewter trans am)
hand ported/milled 317s
PTC 4000
373s
226
full exhaust
In the other race we did I pulled around 3 on him.. I was still pulling when we let out.. I cut 1.47-1.50 short times so I'm sure it would be worse from a dig.

Ahhh, they are getting the job done for now I guess.. Running 7.40@ 92mph in a 2500 DA right now w/ a 1.50 short time.. I'm expecting some 7.1s@ 94mph or so with a 1.47-8 short time next weekend.. Tweaked a bit more here and there and got skinnies for front (was full weight before).
I would most definitely see a gain with some AFRs or the like but I don't see something such as a PRC stg 1 head doing much better at all.. Who knows though?

I am actually very surprised they have let me run the times that I have. They paid for their self. I am curious to what they flow though. I would assume in the 200 range.

thanks.. alot...
The 230/232 was the duration @.050 he was mentioning, not a brand/manufacturer.
Without changing the stall, I would say a 228 duration camshaft MAXIMUM, and use the LS6 intake with it.
PTV is piston to valve clearance, meaning when the valve is at full lift... how much clearance there is between the valve and piston.

I already understand about that.. so ms3 has low PTV and with my 243 ported i will have issues....
so maybe look for a 228R or 233/239 right instead MS3 and change my 222/224 actually?
thanks...
If the 243's are milled at all the MS3 probably wont clear and a smaller camshaft will require less work and will run better for a daily driver. Porting the intake ports wont change PTV clearance at all, just milling does.
Yes to the 228 sized cam, a 233/239 will want more converter than a 3000 stall, IMO.
