Is this manifold okay to use?

[KCz Eclipse]

Alright, i have a previous post about the little cracks in the manifold. I was told no cracks are good so i contacted the guy i bought the manifold from and he sent me another one. After receiving the 2nd mani, it had the same cracks of course, but looked different. After conparing the 1st and 2nd manis, i beleive the first was ported. I hva e no knowledge about porting and didnt notice it until i saw an unported manifold. So i think i am going to go ahead and use the first manifold but not sure if i am able to. I noticed two of the bolt holes have broken off bolts in them, you can see them in the picture. Not sure how important they are. Let me know what you guys think about the manifolds.

Thanks

Oh, i forgot, what is the hole in the bottom manifold that the top doesnt have?

I would use the ported one. The bolts that are broken off are for the manifold heat shield.

Okay, if those broken off bolts are in the holes for the shield, what can i do to make the manifold look better. Im not worried about the heat, just the look. Im trying to clean up the engine bay. What can i do to it to make it look better?

You should be worried about the heat. Having the heat shield is a real good idea to keep engine bay temp's lower. I would just drill out the bolts, and re-tap the holes. As far as cleaning the manifold, a wire wheel on a drill will clean it right up.

i personaly have had luck with ebay manifolds in the past on other vehicles. but that is a risk to take bcuz it might crack. mine didnt and i noticed a nice hp gain and a higher rev limiter. i also know that the 2g manifold is better then the 1g. but for less then $100 the ebay one is a risk i would take again

you can toss that thing in the trash and go tubular. FP has a sale on their cast race manifold looks better then stock also.

That is awful advise. Tubular headers on anything daily driven is a bad idea. The heat produced by them is ridiculous. Plus they are more likely to crack, have warped flanges, they usually change the placement of the turbo so the drain line is at a different angle.

i run tubular on my daily driver at 400hp no problems. if you don't get ebay crap he will be fine. DNP is a very good brand. its not awful advise at all. i haven't had any of the issues you describe what so ever with any reputable brand tubular manifold nor have i seen any issues...or hears about issues related to what you are talking about from any high quality manifold companies. If you get an ebay manifold on the other hand bryan.. Yes that is very likely you get what you pay for, and i paid for a good one. so should OP if he wants something that looks tits and will last!

The good quality manifolds will have support brackets and are much much less likely to crack. As for the heat issue. i ran stock rad hoses next to it about 2 inches away and i got no cracking or anything. im on samco silicone hoses now and still don't expect any issues being 2 inches away from the #4 runner. plus if hes worried about heat he can always wrap the manifold. looks like ass if you do it wrong so im not really suggesting it cause he wants aesthetics. i say go polished shiny DNP tubular and daily drive the shit out of it! You get gains and looks cant be beaten.

The FP race manifold is not tubular, so I'm not sure what you are saying there.

If OP is running a Mitsu-flanged turbo, there is no reason to take a chance on a tubular manifold unless he is planning on putting down some crazy power and wants to lay out the cash for a proven one.

For most any Mitsu-flanged turbo, the cast FP race manifold is more than adequate, cheaper, and much less risky.

plus if hes worried about heat he can always wrap the manifold.

Wrapping a manifold (especially a tubular), increases the risk of cracks due to trapped moisture. Ceramic coating would be a "safer" option, although not quite as effective.

i know the FP manifold isn't tubular. that's why it was a separate sentence, more of an after thought after i typed "go tubular"

whats wrong with running a mitsu flange tubular???? im doing it! i do have large goals in mind but its still a daily driver! And it looks tits! You guys know where my vote is. i've had no problems in the 5500 miles so far of hard abuse. he said He wasn't worried about the heat

+1 to you sir exactally why i dont wrap mine, but was just an idea, like i said and he said, hes not worried about the heat, just wants it to look good. I still say toss the stocker. Go FP or tubular.

There is nothing "wrong" with it. What I said was:

...the cast FP race manifold is more than adequate, cheaper, and much less risky.

What's wrong with running a stock ported 2g or evoIII manifold? People have made more power than what your car is and will make on a ported 2g manifold. Why spend 500+ dollars on something that is in no way needed when the cast will do a better job, be more reliable, and keep engine bay temp's. You can't tell me that there are negative effects from running a tubular header on a daily driver. I've seen melted fans, melted radiator tanks, paint burnt off hoods and valve covers. You are also heating up the coolant and causing the cooling system to be less efficient.

i have no AC so no AC fan. i have no ill effects from running tubular daily at all... ill tell you it day and night man. havent had any such issues because my crap is built right i have never had cooling issues once. temps stay 195-200 no matter how hard i floor it. valve cover is ceramic coated, no peeling. radiator is aluminium, no issues, didnt have issues on the stocker also. nothing melted

bryan, have you even ever had a tubular manifold on a car that didnt have other issues so that you can even prove your statements? how do you know your temps didnt rise cause of a crappy rad core? or other things? cause mine is perfect and can verify that just having a tubular changed from a cast.. havent had any differences at all for me personally.


the whats wrong with the 2g and evo 3 manifolds is that the OP wants it to NOT LOOK LIKE ASS.. your getting off topic.

 

[KCz Eclipse]

Okay, so what about the little cracks? How bad are they? Can i still run the manifold with them?

Ditch it and pick up a 2G and port it, an Evo III (better), or an FP race (best).

Bolt it up, call it a day, and get on down the road.

+1 on this though if hes keeping the 2g manifold


FP manifold Forced Performance Turbochargers: FP DSM Race Manifold

sadly sale is over, so for like 200 bucks more he can get a DNP and it wont look bad or rust. unless you are an idiot like me and scotch brighted the burnt on finterprints

 

[KCz Eclipse]

But the manifold you guys are looking at is a 2g and is already ported.

 

[bryanwheat]

Those little cracks in the collector won't hurt anything. I would bolt it on and run it.

 

[Calan]

If it's cracked, then find another one that isn't, or get one of the other two I mentioned. If it's just small surface cracks, you can get away with it for a while...but it will get worse.

The problem with cracks is that you don't know how deep they go, how much they are opening as the mani heats and expands, or if there are more on the inside.

calan is a wiseman for a reason......

 

[Calan]

Pfff... that is common sense. Doesn't take a "wiseass" to know that.

 

[bradselph]

I would double check the crack on the top one were the 4 turbo bolts are on the top right and bottom right,

its good info, thats all im sayin, i wouldent have thought about that off the top of my head. im still 100% for a DNP i think everyone should have one. DSM flange or not they are good manifolds. my next one ill be attempting myself we will see how that turns out probably devided T3 for the hx40 top mount? perhapse! need to get ahold of SS donuts!

 

[KCz Eclipse]

Well what do you guys think about the cracks in the picture. im sure the location of those cracks is pretty common. Do you have any prior experiences with similar cracks?

The cracks are on the thin metal peice

you can always run it and if it gets worse replace it then. or replace it now. if it was me.. id replace it sooner then later. you never know when one of those cracks can open right up and shoot out 1200 degree gasses all about your bay making everything black.. (thats a little over dramatic but you get my point)

i wouldent recommend it as a long term thing. unless you like doing turbo/manifold installs
