manifold swap, 2g on a 1g Options

[treydawgs4g63T]

I have a 2g intake manifold that Im going to port the hell out of and put on the awd. Not sure what all I have to do to make it work though, does it just bolt right on or do i have to switch out some things? Any help will greatly be appreciated.

Thanks

you need to do some more research, but the short answer on this is that you're not going to gain much with this 'mod'.

the 2g intake manifolds were designed with port velocity in mind, which is why 2g heads and intakes had smaller cross-sectional area than 1g's. Most guys go with 1g heads and 1g intake manifolds on their 2g's for a performance upgrade though the benefits of this on a relatively mildly modified 4g63 is still questionable.

Basically, it's not nearly so simple as hogging the thing out with a grinder and more than likely you'll end up hurting performance. There's a reason why porting is considered by many to be a black art and to do this properly you'd need a lot more information, skill, and access to tools like a flow bench.
