These ports are finished, but the manifold hasnt been cleaned yet. Ill have pics of the lower manifold in a few days when I finish it.







If anybody is wondering, my manifold is ported the same, and I was very impressed with the results.

OMG Node you're getting a T2? SWEET!

BTW my N/A 1st-gen eats T2s Well it did before it got so hungry it ate one of its apex seals Next one will be better, faster, stronger...

My friend had porting done exactly like that and we could barely feel a difference. I don't think it does much andis kinda a waste of time. the only thing that is realy worth it is matck the manifold to where it bolts to the engine and thats it other wise save money and eventualy tear it donw and do some realy porting. just my thought....

Suck turbo exhaust

mazdaspeed7

Your friend must have not done something right, because the 2 people I know with ported VDI manifolds here(me and PP13BNOS) both felt more of a gain from the ported manifold than from full exhaust. We both have true dual exhaust, too.

Node, by the time you start modding that car, I will have a ported engine.

Ok, how much to do this? I wnat to port my manifolds, but I am very leery about it cuz I have never done this sort of thing before! How much would you chare to do this for me?

von

Money....lolol.... If u dont have a dremel then 60 bucks will buy u one. or go rent one from home depot. The rest is free bro... Unless U plan on braking something like those plastic injector atomizer things on the VDI manifold.

I have a Wizard (different brand than a dremel, but essentially the same thing), I just don't want to screw something up! After my little accident w/ misgrounding the battery, and almost frying my ECU, I am a little more careful now!So I just port match the upper, middle and lower manifolds? How deep do I grind into the runners?

von

I think the pic explains it... U see how roughf it gets in the pics... I would say right thier. Like what was explained earlier, the runners are fine. Its the flanges that reduce in diameter that need to match the runners diameter. And the flange length isnt that long so A dremel or wizard is all u need. Yes do the whold thing and dont forget to port match the lower to the engine too. I would thnk u can just stick a wet rag in the engine hole and grind enoughf to match it up then get all the shavings out. Since your going to be down thier u should get the 6port racing sleeves dont ya think?

von

My ? is how would I know the sleeves are alined and what type of glue would work.???????????

von

DOnt forget too let us know the results AGENT.

That was my thought as well. I think I will surf on over to Pinapple right now, and do some research!

I am not porting manifolds for anybody else. I HATE doing that!!!!!!! Mine didnt seem so bad, but once I started doing his, I realized just how much porting sucks to do. Its not hard, just time consuming.

If anybody is planning on doing it, a picture is worth a thousand words. Look at your manifold, compare it to the pics, and youll know where and how much to port. Its that simple. Just keep an eye on the thickness of the alum, and you wont have anything to worry about.

Cool. I will try it next weekend. I will block off both days to rip into my engine! Thanks anyway, and for the info mazdaspeed, as always!

looks like pretty soon that vibrating head will take over his avatar. funny how quickly he turned into a turbo guy. no offense
