extrude honed

[XdsmdemonXRS]

Ok i did a search and most of the topics were about the Turbo Inatke Manifolds being done. So, my engine builder told me about extrudehone.com to have my intake manifold done . I contacted them and they came back with a quote of 495 dollars plus an additional 80 dollars to gasket match the ports( oh and plus shipping ). So, first of all, is this worth it instead of either buying an OBX manifold ( 200 bucks) or is there a better solution for a better intake manifold over stock?

This is for a 96' Eclipse RS 420a with N/A built Motor.... Thanks Guys!

i say go with the obx manifold and your bored out throttle body

or venom like dsm-zero his looks sick

Go with either OBX or a Venom. They are both cheaper than what you got priced.

I would recommend a CNC port job on your stock intake manifold.

Nemo down at Rage-Tek is the man when it comes to 420A motors. Call him at 954-915-0016

Unfortunately there currently aren't any good alternatives to the stock intake manifold.

If I were going to go all out and spare no expense with the stocker, I'd get everything ported, then extrude honed. As you know, that's quite a bit of money -- something to really only think about when your HP numbers get up there.

Please don't get an OBX or a Venom manifold. You would be better off keeping it stock before waisting cash on those. Either port it, gasket match it, and extrude hone it or just leave it. Thats my .02. Don't waste money.

While I like the idea of extrude honed, I don't think that's gonna help you all that much for your $600. In checking your profile (if it's up to date) I would highly recommend that you stick with stock with maybe a dremel/diegrinder polish. Match port where necessary (remember to leave your intake manifold match just a tiny bit smaller than your intake ports). Your mechanic probably recommended it because it is a good idea to help flow, but unless you plan on a really heavy build, I can't see the use in it.

First of all, thanks for the reply and i just did update my profile, been meaning to do that , sorry it took so long, and thanks for the advice, I think ill save my money and go your way , makes the most sense....i am rebuilding my motor currently ( as you can see by my profile) , but only looking for somewhere over 200hp to the crank....thanks for the help!

Just to let you know bullettdsm is the fastest no turbo, no nitrous 2gnt. He's only making 176 hp to the wheels, so good luck with you build of over 200 to the crank...

I am very aware of this , thats why i take his advice over most . I just set the 200hp mark as a goal. My main Goal with the entire car was to make it better all the way around , not just HP. Plus, I like the idea of beating up on Hondas with an N/A built motor so they cant cry "turbo" or "nitrious"!!....just my .02

EH the stock I have an OBX which I am going to use for a month or two till mines comes back from the shop, the OBX has to be drilled and tapped as well as a few more bugs to be worked out.

The OBX is not CARB legal either.

I look inside the OBX and IMO it looks like a monkey did the work hehehehe!!!! The runners are not flushed, the holes in the back look like crap too both on the back! and no place for the air sensor to be installed on the end.

You buy it You like to work...Badddd!!!!

I'm pretty sure the OP had already made his decision, but thanks for the info

To Fullmoon WHat did you have to have done to the obx to make it work cause I was at this local exhaust shop trying to get them to help me get my old exhaust off to get my xtune cat back on and a guy was like I have a obx i'll see it for $20(That is not a missprint that is twenty dollars) So now I'm trying to find out exactly what you have to do to get it to work.


By the way to everyone on here you guys should go to the 4g63 section and do a search on intake manifold test and look at the results. You guys say there are no good intake manfolds for our cars and that the obx and venom are bad(which they aren't great that's for dam sure) but you need to understand that aftemrarket manifolds only really shine is the upper rpm range or when your outflowing your stocker. If you look at the test I'm talking about you'll see the stock 4g63 manifold not ported or anything outperformed even the magnus(for those who don'pt know thought to be one of the best smim's out for the 4g63) untill about 6k then the magnus started flowing more so I think you guys just have to understand the purpose of a aftermarket manifold not that some of you don't like SHIT paul builds stuff like that. Point of my ranting is if your not boosting and running your car to high rpms your probably not gonna see any gain from any of these manifolds.

Before you go any further, please remember and realize this is not the 4g63. These are not the same cars. The products for the 4g63 are NOT available for the 420as. Comparing these two is not relevant enough for debate. The 4g63 manifold was designed with forced induction already in mind. This is not the case for the 420a. Also, we have different flow characteristics and set-ups. You run on MAF and we run on MAP. These two are different also.

There are only TWO intake manifolds available for the 420a. One is crap, the other is OK, but the stocker ported and polished performs better then both by far. As most of us know.

I still don't understand what you think we don't understand. I guess I'm suppose to understand other manifold's flow better then stock? Or not? I don't understand when to purchase a new manifold because the stock has been outflowed? It's not like we don't understand this shit dude, we have nothing to apply it to. We can't take a line-up of manifold and see which performs better because there are only a few available. Again, this is generally speaking from the 420a standpoint, seems like you are representing the 4g63 standpoint.

Why do dead threads have to be resurrected? Could you not have just pm'd him about the exhaust if you really wanna get that $20 sweet deal?

If you did any research you would see, that some of the main complaints about the intake manifolds in our market are as follows: not that they don't flow better than stock or what not really, but the simple fact that they aren't even worth the trouble it takes to even get bolted on in the first place. etc etc blah blah blah

Again I did not say that no one understood the point of a smim but it's obvious when you see guys with I/H/E and a obx thinking the obx is gonna give them 30whp and when it gives them 4 they say its' a POS. I'm talking boosted 420a's period. My point of view is not from any impiticular engine but forced induction concepts. I'll put it to you like this if the stocker ported and honed was the BEST for our cars no matter what compared to the venom and obx why do guys like DSM-ZERO with shit loads of money and custom parts descided to run one instead of the stock unit?

I already have the manifold I wasn't asking if I should take the sweat deal I took it. I just wanted someone to post what exactlyhad to be done so one I could do it and two so someone could see the work involved and then descide for themselfs if it's worth it to them for their setup.


By the way I did search and I'm quite aware of the fittment issues.

Why do dead threads have to be resurrected?

So your cheery and helpful Moderators don't have to MERGE 30 threads about engine shipping, 20 about car shipping, and 16 about transmission shipping.

And so I don't have to, either.
