Pina Motorsports Evo3 Porting..

[Chicago1]

Well I got my Evo3 manifold from them a few days ago. It was 160 so I was like sweet. Well the guy on the phone asks if I wanted it ported I said sure. Well I got it 2 weeks later since the address was written down wrong and FedEx couldnt find my place. I called Pina and they where helpfull in tracking the manifold so that was cool. Well I get the manifold and man was I pretty dissapointed. Well only about 5 inches of the collector area was ported!!! I mean it doesnt look very good. I could of done that in 20 mins of my own time with a dremel. Well I call them and Will says that they thats how they do it around there and it optimizes flow and the runners arent necessary etc etc since it doesnt do anyything. I'm like hmm that doesnt sound right. So I go back look at it then get on slowboys site. Well I email Pina and they assure me they charge the same as slowboy and do what slowboy does. Well I told Will to take a look at slowboys site and how they open up theerunners, port the runners and the collector area. He basically said in a nice way, "Well to bad your screwed but if I needed anything in the future they would take care of me." WTF?!?!?!? Anywayz there the cheapeast I have seen Evo3 manifolds floating around (160) but DO NOT let them port it. Have it done else where. I mean even the colector where it connects isnt even round. I'm not pist at them but just dissapointed. Now I have to take it somewhere else and it's just gonna end up costing me the same then if I got it from Slowboy and had it ported.. Lesson learned

Any pics of the port work?

(stupid 10 character minimum on posts. :rolleyes: )

How do I post a pic here?

Why would you port the runners, you wouldn't be able to maintain a constant diameter all the way to the collector. You want it consistent. You would NOT see any increase in spool time by porting the runners on the evo manifold, it's not even equal length.

Slowboy is a reseller, and are laughed at by guys on NABR. They would be the last DSM shop I dealt with (aside from all the dormroom types).

generally the collector doesnt need to be ported much either, it's already 7cm. The step can be removed however.

[Towelie]

you want to make flow as uniform as possible, not do a little porting, here and there and disrupt it. the only thing I would do is take out the step at the collector to match the turbine inlet.

Stock, the pics have beem sent. My point being is when you see the pics anyone with a dremel and 15-25 mins could of done that. I could of saved 40 bucks.

Pina charges $65/hr for labor. You got a good deal.

[onegeeTSI]

Buying a dremel and my time = worth more than $40.

[slugsgomoo]

that looks right to me. I don't see how you could port the runners in the evo3 housing. Are the exhaust ports on your head ported? If they are not, I don't see why it matters, since the evo3 runners are already larger.

The fact of the matter is, it's not necessarily the size of the ports that makes the difference, or we'd all still believe that the 1g head flowed better (and it does until both are ported properly) however sometimes it's flow angles and the merges.

I would port the head side of the runners if the openings on the head had been enlarged past the size of the evo3 manifold. I would not do so otherwise.

[Gomer_GSX]

With such high nickel content in the new Evo3 pieces, that makes it hard as hell to port these pieces. As most of the guys above mentioned, half the porting you asked for was unnecessary and secondly with any sort of dremel the high nickel content is going to make it very tough to port it very much at all. Also, why did you need the porting in the first place? Your car appears to be stock so the ported pieces will not match up directly flow-wise to what you currently are running.

Well I'm starting to mod little by little so I figured I might as well get it ported so when I get the rest of my mods going everything would be good to go. if you guys are saying its ok then well it's ok...I have another q. how much larger are the runners supposed to be on an evo3 compared to a 1st gen? I measure them and the evo 3 is like 1mm bigger you cant tell the difference between the 1st gen and evo. Or am I just blind?

[MackZ24]

Looks like a fairly well done job to me. Very uniform, and as everyone else mentioned the rest of the porting is unnecessary, especially in your application.

I think my point is being missed here regardless of my application now where talking future plans, but I thank everyone for there input , I'm not trying to be an ass either. I am trying to learn here :) . You guys say thats a good job for 40 bucks then so be it. IMO and from what I have been hearing around other dsmers, Thats could be done my someone who has never even used a dremel and about 20 mins. Now do I have to order the gasket or can I get it locally at a dealer? Thanks again

Seriously, go get a dremmel ($60) and a carbide porting bit ($25) and then spend the next 10 hours getting about half that much done. No joke. High Nickle content Cast peices are HARD as hell. They eat through carbide bits. Even using a nice carbide bit on a die grinder, after 3-4 of those kind of port jobs the bit will be usless, and they are about $45 each; Id say your money was very well spent.

Try porting that manifold with a Dremel and you'll "learn" just how difficult it really is.

Your point? Let's see here, you get a ported manifold for, from what I can tell, is the best price around. Then you get a good deal on port work, and your ignorant ass starts bitching about it.
You obviously have never ported anything before, and from your incoherent babbling about porting the runners it is clear that your understanding of physics and flow rates is somewhat like your understanding of Chinese.

[kobykris]

I pee on little childred because of your comments.

Obviously you have no idea how a manifold is properly ported, let alone talking about the subject.

[SilverBullet2G]

You got a good deal, good luck trying to port that for less than $40...

Those are pics of my Evo III manifold (which I also purchased from Pina) while I was finishing up grinding the ring down. I ported the manifold myself with a Dremel, which took 2 days and a total of about 6-8 hours. After it was all said and done, I chewed up 2 carbide bits and a handfull of the grinding stone bits (which work better, IMO), which arent cheap. I'm somewhat meticulous with my work, and also decided to port the divider down and to a point for better "merging" of the exhaust gas from each cylinder. In the end, I paid a good penny more than what you did for your port work. All this has been meantioned, but I will meantion them again.

- You do not need to port the runners (especially at your power level). You also want a consistant passage through out each runner, no bottlenecking, which is already acheived during casting of the manifold. The collector area is the only place that could use attention. Grind the ring down and smooth, and opt the cut the divider down some like I did (not a necessity though).

- The cast that the newer Evo manifolds are made of have a very high nickel content, which makes them quite stubborn to port (especially brand new). I chewed through two carbide cutting bits, and probably about 5-6 grinding stones doing mine. If I could do it over again, I probably still would've done it because I like to do my own work. But I certainly would refer to other means of porting rather than a Dremel.

Just a piece of advise, don't go bashing a good and reputable shop all over the net, ESPECIALLY if you are new and don't know what is necessary. If you don't know, ask Will, Nick, Andre, or Justin at Pina. If you have a question about Pina and want some first hand customer experience, then PM or email one of us here in the state who are regular customers of Pina, and we will shoot you in the right direction about the shop. Pina stands behind their product, their work, and their customer service.

Good luck!

You don't need a gasket between the manifold and turbo. BELIEVE ME.. i've been running like this for about 3 years now, with NO EXH leaks (at least not in that area).

(correction.. if everything is right and straight and flat, you won't need a gasket... i've put old 14b's back on with no gasket and no leaks though)

Or you could spend a few bucks and do it the right way. Just becasue it works doesnt mean it is done right.
