1. Would it be better to port the stock manifold or go with an aftermarket exhaust manifold?
2. Is it true that if you get an aftermarket manifold that you have to upgrade you injectors?

 

What you should be trying to figure out is how to use the search feature.....


But just out of the kindness of my heart, porting is the cheapest and best way to go at the moment. The only mani that made more power when Buschur did testing was the full race manifold when talking about stock turbo mani's. Buy the Megan if you want it to crack and "spit hot fiya" all over your engine compartment.

 

Porting is cheaper, about $200 but you have to provide Buschur with the mani if not then he'll add $300 until you ship one back. Cheap mani like the one on Ebay will crack, but you're looking at $800-$1400 for a mani from Tomei, JIC, Jun or HKS. If you want a mani that still retain some what of a stock look so you won't get harassed by the cops then the Tomei look some what stock with the heat shield on. Check out www.bulletproofautomotive.com they have it and someone on this forum has that set up as well.

 

Am planing to get megan manifold they say's that it been dynoed with 15hp

but i dont know anything elas and i guess its has a good price its only 200$

 

Either get the coated/ported stocker from PPI or get the Full-Race...

 

+1 on the PPI! Wayne is the man!

 

These r some great responses. 20psi Im tryin to get my post up so I can buy from the for sale ads.

 

i purchased a stock exhuast manifold for $48/shipped. Just back from vacation today and had it sitting on my door step. Planning on sending it out to PPI when I get some time. No down time or core charge.

anybody know how the invidia manifold is?

 

Naw haven't heard anything bout them.

 

Has been edited, check out this post again.

 

I had a DNP manifold and it worked flawlessly... No cacking, and provided a couple ponies for what i paid.

 

Really though I was told if you coat the flanges it will decrease the risk of cracking by a ton!

 

Ported and coated stocker...nice SOTP gain.

 

Stocker....cheaper Aftermarket...looks good but a lil pricey. Also I have the exh temp in my manifold. If i get an aftermaket one, i would have to get a bung welded in
