just a quick question. does the 2nd gen exhaust manifold just bolt right on to the 1gen? or is there some modifications to make it fit properly? which would be a better way to go... a ported 1st gen manifold, or a 2nd gen manifold?

thanks

I think you'll want to do just a touch of grinding on the lower right hand corner if you're looking from the front of the car where it bolts to the engine. Otherwise, I think it's a bitch to get in. This is all coming from memory, although I do know that my EVO manifold had the corner ground down so it would fit mine. I'm looking at it right now, it's sitting on my desk

People contend that the EVO is the same as the 2G, so I would guess you may want to.

Here is a link with the info on the 2G manifold, along with the small modification that must be done to it so that it fits...

BTW, go with a ported 2G maniofold, which is 100 times better than a 1G one. Better yet, go with an EVOIII one, it has a bigger collector than the 2G one.

Get the EVOIII Manifold as Blackboost said. It has a higher nickle content than the 1 or 2g. Might as well port out the collector area while your at it. The corner will have to be trimmed but it's easy with a cutoff tool or dremel with a cutoff wheel. Took me 2 minutes to make it work.

what type of gains are realized by going with the 2G mainfold? Is it really worth doing with the stock 14B? I am planning to upgrade my turbo when the stocker dies, and was going to look into it then. However, if it is a good mod, I might go at it when I install my exhaust.

It is worth doing on a stock 1g.. mainly because 100% of 1g DSMs I've seen has had a cracked manifold (stock 1g mani). Every single one!

Plus the stock 2G manifold flows a lot more than a 1G one given it's design: http://www.vfaq.com/FAQlocator-index.html.

would it be ok to pick up an exhaust manifold off an eclipse in a junk yard? or is there something i should look out for? or is there somewhere else i can get one? i read that page and understand what i need to grind off so the corner clears teh engine mount... how much does a stock exh manifold cost? how much do you think some place would charge me to port it? or how hard is it to do it myself? i have the tools, and plenty of time to do it in. or is this something i should have somebody else do...

thanks

Okay, visit the porting section at by yourself. You can do it, if you ...rry the exhasut manifolds that the guys were talking about in here (2G, EVOIII)
