I need your opinion...

Megan racing manifold (for stock turbo)

or

OEM ported and coat manifold (for stock engine)
(by Buschur racing)

Thanks

 

I have no doubt that the ported and coated stocker will be much more durable and reliable over time than the Megan...and on the stock motor/turbo I am willing to bet the performance gains will be similar.

Good luck.

 

Stock ported works great. Megan will without any doubt crack.

 

did someone bump this thread from like 7 years ago ? There are so many threads on this damn board concerning the megan O2 and manifold and stock ported coated....

Summing it up...
Megan O2 is great and works, the mani's are ify...

Hope this helps.

 

I had the megan runners until i swapped to a 3076 no problems on mine.

 

i think you have them confused with the megan mani. thats booty. but i have had their O2 housing for over 4years in LV, NV, three different turbos and i havent had any issues with it. im sure it cost less and weighs less than a stock ported. but the stock allows you to put on the heat shield if you want. and support brakets for the turbo.

 

Stocky ported works wonders

 

avoid megan manifold serious waste of money if you want one you can buy my cracked one for the price of shipping and just weild it LOL

 

Are you serious?? That is hilarious that you bought a manifold, and removed the runners for new ones Should have just bought a flange a good collector and done it from scratch to begin with!

BTW, it's been proven time and time again, not much beats the stock, ported, coated manifold.

 

Alot of people don't think their manifold is cracked.
Whenever we ceramic coat them, because of the prep required, we've seen alot of manifolds that "look" fine on the outside. Smaller cracks are covered by carbon buildup and sometimes are hard to spot.

On the other hand, we've NEVER seen any cracks on a stock manifold or a good quality tubular manifold (shearer, punishment, full-race, etc).

 

I picked up 6whp/12 fpt on a dynojet with these so it didn't help that much

i have a totally different turbo now so i have a divorced setup with a dump and equal length runners

 

my megan manifold has also cracked. I vote for stock ported.

 

I thought we are talking about the exhaust manifold

Megan o2 housing is a whole different story. I run one without issues.... well sort of, I think mine has a crack but that probably because I ported it too much.
