Stock Manifold or SSAC? [Archive]

I have a stock sr20ve exhaust manifold with about 2 feet of the secondary attached. I had a recommendation to simply use the stock manifold on my VE and to weld that secondary on to the rest of the exhaust instead of using a 2.5" SSAC. I'm searching for a comparison of the two options but so far I can only find threads from 2005 or so that indicate the stock manifold is quite restrictive. Is that correct? Should I just port match the SSAC like most others and call it a day?

In the same boat as you my bro. Lots of peeps port match but I would like someone to post some hard facts/figures/gains.

Are you saying that the stock header can be used with a little bigger secondary?

Peace

Nice to know I'm not the only one! I'm not saying anything at all. I'm just wondering if the stock header can be used without choking the VE more then the 2.5" SSAC. :) I even have a good section of the stock secondary that I could use though it does look a bit smallish in diameter. I guess my inclination right now is that the stocker is just too small and even if it fed into a 3" secondary and catback it would still be too restrictive. However, I'm a novice so it's nice to hear from guys who have some real experience.

Go with the SSAC. It's not worth the time to finish the secondary and if you have to pay someone to do it for you, you are already at the cost of the SSAC. You will make more power with the SSAC also.

I had the stock VE manifold on the car and then switched to the SSauto. I gained like 5 or 6hp from the swap. Can't rem if I lost any TQ or gained any. You can do 170whp with the stock manifold.

I made over 200 std whp with the ssac and so have others.

Have not heard or seen others making over 200 whp with the stock headers.

I'm convinced. SSAC it is. Thanks for your replies.

Well good questions should always get replies. When is the swap going to happen?

ps: pm me a link to the header you buy. I need one too. :)

not only on this forum but others have verifid that the ssac header is way better than the stock. one reason for the no issue is that with the tune as in what ur done to ur car u will see bigger gains......

Benito,
The old motor is out as of this evening. We have the VE mostly prepped for install. It should actually go in tomorrow given we can resolve a couple of issues (trashed engine mounts and stuck tranny bolts). Feel free to stop by anytime this weekend as I'm sure we'll be working through Sunday. PM sent as well.

How much better will the OEM VE manifold and downpipe be than a port-matched stock DE manifold and downpipe? If I have the opportunity to buy the downpipe for, say, $30 or $40, would it be worth it? Otherwise I'd wait a while to get the SSAC...

For that matter, will the OEM VE downpipe fit without modification? (I have a highport P10, in case it matters...)

Ur trying to bolt up a VE 2ndary to a DE primary? I don't think they will fit.

No, I'm looking at two different options:

1. Use VE primary that comes free with the VE I buy; buy VE secondary for a bit more and use that.
2. Take off VE primary, port-match DE primary and plug EGR hole, use DE primary and DE secondary.

I will admit that I am a cheap-ass who doesn't want to get the SSAC right now. It will probably come eventually, but if the VE header is a 6whp improvement over the DE header, and the SSAC is another 6whp over that, it makes sense in my mind to get the VE downpipe.

ohh ok. Well if u can get the VE 2ndary I would run it and save a lil money. I would never ever use that DE manifold it would kill HP big time on the VE. Stock VE manifold or SSauto or balling 4-1 header!.

I bought a SSAC header and made a few physical comparisons:

Primaries on SSAC are larger:

Secondary ports on SSAC are smaller than stock! Wnoder why it's desined that way?

Also, noticed that I wont need to do any porting as the VVL gasket matched perfectly with the SSAC header. If anything, I may have to cut some sections on the stock gasket, since the ports of the header are larger. (prefer to use the stock one over the SSAC gasket)

Well I guess the proof of the pudding is in the eating.

Peace

I have a question that hasn't been quite cleared up...ve primaries to de secondaries? Will these even bolt up?? Despite the obvious restrictions and associated losses. Thanks.

Nope, and even if they did, the VE primary is too long, so the secondary would be scraping the ground.

BTW, I ended up getting the SSAC anyway, because according to people I've talked to, I'll be able to reuse my current clutch, so I had some extra money in the budget.
