1g exhaust manifold

[1fast97gsx]

I've never seen a 1g manifold in person .... but how much porting can be done to these? I would like to have a 2g mani, but they are really hard to find. How much can I port a 1g manifold in relationship to a 2g? And what parts of the 1g mani are most restrictive compared to the 2g?? Thanks.

Don't waste you time, most of the used 1G exhaust manifolds are cracked in one or more places. If they aren't it's just a matter of time. Get either a 2G or a EVO III exhaust manifold and go from there. Both are less than $200 new.

MD 308197 - List @ $232.78 - What about the EVO manifold from our Vendor? I'm wondering if I shoulda got that instead of the 2G?

Now I don't know about Evo Exh Manifold clearances - Fitment - etc - The 2G is strictly bolt-up - I have one.

well my car had the 2g mani stock .. I made the mistake of selling mine during my downtime because I had a custom mani in the works .. now I just want to go back to the stocker. Damn it sure sucks selling parts and then needing them later :thumbdown

I have a EVO III on my 91.

It should be a direct swap for a 2G, I had to grind the one corner just like you would with a 2G manifold. I also forgot that using a 1G on a 2G would require you to drill out the two outer most holes on the manifold to clear the two 10mm studs on the head.

ok cool. Right now all I want is a junkyard manifold to get the car running with and then I want to just order a brand new evo or 2g mani. I'm probably just gonna use a 1g for a week or 2 unless a local junkyard has a 2g there.
