extrude honing stock intake manifold

[Constant_Project21]

Didn't know where exactly to post this, but I am wondering if anyone has any input on doing an extrude hone on a stock 1g intake manifold. I know those crazy 16g guys at english racing, DONT use a SMIM, they did extrude hone on a stock manifold (it seems to be doing pretty well on their car).

I guess what I'm asking, is it it worth it? Planning on doing a mild port on my head, and depending on what I find, maybe some oversized valves.
My setup SHOULD be like this-
2g piston/1g rod combo 2.0l
evo3 16g, ported, prob around 26-28psi
e85 (1450-1600cc injectors)
link
272 cams of some sort (prob hks)
light port work on the head, oversized valves, aftermarket springs and retainers
external wastegate
Fmic of some sort
N/A tb
2g manifold heavily ported (possibly an fp race manifold, again, its dependent on what I find)
4 inch exhaust (I realize its overkill, but dont care, going for sound on that one)

That's the jist of it, I obviously didnt cover the entire mod list. Also, if you know of a place that can do extrude honing, that would be helpful :)

Thanks in advance,
Dan.

I remember reading about it on another forum about it being very expensive and not getting much gain from it. Also you can get away with much smaller injectors. I maxed out my 16g (30+psi) with fic 950's at like 45% duty cycle.

100% not worth it.

I'm getting big injectors, so I never have to upgrade. Eventually would like to run a borg warner s259 or a fp3065, so planning ahead.

That's a little disheartening about the gains not being good, I'd only do it if I can find somewhere cheap to do it.

i would say its not worth the money at all, x2 on injectors not needing to be that big, but if you plan on going bigger eventually then thats cool. i would get a 2g head and an fp mani also.

Waste of money. My buddy had it done to his supercharged SVT contour, and barely saw any gains. For the money, just find a used Magnus or another aftermarket IM.

It works well on other applications, just not ours.

^truth.

Umm, the CSVT all ready came from the factor with an exude honed intake manifold, this was one of the many differences between it and a standard 2.5 Contour. Correct me if I am wrong, but once the manifold was allready honed, there would be little to no gains by repeating the process?

^^I would imagine.
SO, I'll prob stray away from this. I wasn't looking to buy a SMIM, just cause it seems overkill for a 16g, but if the right deal comes along, I'll prob end up with one.

Thanks for all the input guys!
