I put an sh***y ebay manifold on my car and go figure it has now obtained a few cracks on the welds. i bought a used DC Sport manifold from a goo friend with approx. 2k-3k miles on it. so what im trying to figure out and get some good suggestions as to whether i should go with changing to the DC sport tubular, or get my stock one port and polished so i can piece of mind knowing i will nott have to change it again. at least until i do a turbo kit upgrade. im also looking into a water/meth kit so idk how much or if that would change any of the answers?? thanks for the info fellas

 

If you plan to keep a stock frame turbo or something of the like, stock ported and coated will be your most reliable manifold for the price.

 

DC is crap just like the ebay one. Get yourself a good stocker and have Map port it, coat it and your worrys go away.

 

i figured it was garbage as well since i got it for dirt cheap with only that many miles on it and definetely appreciate the second input i took the stocker off when it had about 35 k on it and its been just sitting since then. will that have any effect of the performance?? or will the port and coat take care of any BS i could encounter?

 

and not to get off the actual subject but i also have a completely stock VIII turbo w the same amount of miles as the dc manifold. think it would be of any help to switch it out w my old one since it may be easier to take the whole turbo system out anyway to put in the manifold? figured it couldnt hurt to put a newer turbo in if im not mistaken??

 

I've always been skeptical of the DC unit...looks like a copy-paste design of every other cheap tubular manifold found on the market..

How would a MAP ported stock manifold compare to their short runner manifold in terms of spool-up & power gains? A ported/coated stock manifold is in the neighborhood of what the short runner manifold costs...anybody with experience with both?

 

i really dont have much experience besides dont buy a cheap manifold of your f#$@ed!! lol im just looking to get the stock ported/coated because im in need of a solid manifold that i can rely on w out having to replace until perhaps a turbo upgrade. in which case it would come w a fresh one. And thats a great question because i would also like to know what the difference between the 2 are as far as power and price.

 

Take the # in this graph for ported mani.

Compair it to the short runner in this graph.
