15 lbs at the moment cuz my wastegate spring is to small my controller is maxed out, and i have a mani gasket leak the size of mars so my afr's were pretty off.. i was running really rich

 

^^ too rich afrs can cause high egts too! residual fuel not burnt in the cylinders will continue to burn up to your exhaust manifold but thats when its too rich rich rich

 

i agree with rythm.. i opened this expecting to see a blown motor/trans.. axels gone.. and in the process of that you crashed it into a tree...

CRACKED MANIFOLD???????????

dude, seriously.. everyone who builds their motors goes through a few of these...

no biggie.. swap it out and youll be fine.

 

:D brandon ya but the thing is i cant keep running these log manifolds.. they just keep cracking lol, so i need a diff manifold and have to fab everything up to fit it..

 

I would agree if this was a Tubular manifold but log manifolds made from Sch 40 304 SS are damn near bomb proof.......however. If you do not use the supplied spring bolts that are supplied with the kit you then remove the area that is supposed to pivot. Without this pivot point you have an exhaust that now acts like a giant pry bar.

Without the springs in there to allow flex, you now have a full exhaust hard bolted with no flex point. Over time the movement and vibration will crack any weld.

You need a flex point. Whether it's a ball and socket using springs or an exhaust flex joint.

As you all can see here by the pictures that SoFloTC sent us of his setup there are no spring bolts used.

The stock header to S-pipe come with spring bolts, we supply spring bolts for the new s-pipe and downpipe. If they are not used you remove the flex out of the system, if you remove the flex out of ANY car with a turbo on it you are guaranteed to crack a manifold. In the final picture you can see that the flange is bending as well. It should not bend, because there should be a spring bolt assembly used there. There isn't even a donut gasket in there. WTF????:/

So with that said.............how is this Dezods fault?

We spend alot of time, effort and MONEY to make sure our products are as user friendly and dependable as possible. We do our best to take care of any customer complaints or questions. We must draw the line of where we take fault for something, especially when this is clearly not a manufacturer defect but more a user install error.

We provide clear instructions on our website about installing the kit. If you do not feel confident with those instructions to install the turbo kit then I would recommend taking it to a performance shop that is experienced. If someone else installed this then you should be seeking compensation from them.

We offered you a manifold at cost the first time not even knowing the circumstances. Now knowing the circumstances of how this failed we are expected to offer you a free manifold. I'm sorry but I just don't see how this is our fault.

I'm really sorry you have had this problem. If this was our fault I'm sure we could do something to take care of you but in all the kits we have produced and installed we have not seen this kind of failure. We have customers that still have their kits and have put over 60k on them. No problems.

We also have sold more kits than anyone out there so to compare Turbo Toyotas or any other kit to ours is like comparing apples to oranges, not to mention that with more kits out there pure math states your odds are higher for complaints. Which I might add, we have had very little and when and if there are problems we address them.

It's a log manifold, it's supposed to be simple to avoid these problems. It's a fairly simple kit that is meant to be reliable and supply decent power. There is very little to go wrong on the kit. I hate to say it but 9 times out of 10 if there is a problem it's usually a user error. Those of you that think that a tubular weld elbow manifold is stronger are completely wrong. Properly designed tubular manifolds have the capability to make more power on higher boost levels but they are heavier and much more prone to cracking. For proof of this do a search on Honda-Tech. That community has been turboing cars longer than any other sport compact. Big names like full race, AFI, Omni fab etc. All of them fail and they all have problems over time. It's the nature of the beast sometimes. While log manifolds may not make the most power they are hands down the most reliable due to their simple construction next to a cast manifold.

Everyone is right though, this is not a career ending failure. Fix it and keep trucking.

 

Yeah, that's the thing, I'm really hoping to build up my own kit, starting with a turbo and el mani, but my tC is my DD and I would be able to have that down time for fabrication. Good luck man!

 

would be nice if i had gotten those spring bolts

 

and the funny thing is u said the vibration over time.. ive had my car for 2 weeks lol...

 

looking at log style manifold they look compact and strong, its funny though i see log manifolds any brands failing.. i have yet to see a tc tubular manifold to crack.. maybe coz there isnt as many out their yet. But I didnt have a flex joint on my tubular manifold until 9 months being boosted and only 15K on the turbo kit but didnt have that problem, we'll i hope i wont have at that problem at all

 

The only log style I have ever seen fail is the cheap chinese knock offs. Those things are made from steel that is too thin to be used in that application and not welded properly. These manifolds are Sch 40 304 SS, back purged when welded. The only thing that will make them fail is lack of flex or extremely high EGTs but that is even rare.

 

All kits come with all the hardware needed. You ordered your kit about a year and a half ago at that time the spring bolts would have come in the box with the down pipe. Do you still have this box? The spring bolts would have been in a plastic bag with the donut gasket. We pack all the kits here and have a checklist that gets signed off on by the packer each time.

 

well i had it for 2 weeks, witha great DD tune.. i couldnt beat on the car at all because of the giant leak.. the turbo wouldnt even spool til 5k lol.. clearly something else is wrong... with the manifold..

 

Don do you have a link for those spring bolts ?

Even still just normal driving with bumps, pot holes, engine movement from being on and off throttle ALL cause vibrations, which can lead to failure with improper hardware installed.

Edit: Should be just like OEM w/ donut gasket and spring loaded bolts

 

Clearly something was wrong wit h the installs. Your pictures prove that. There are many members on here that have had their Dezod kits for a long time with no cracked manifold. My guess would be that they installed the spring bolts and donut gasket. I'm not sure how you had a good tune either or how your tuner didn't catch the fact that there was no gasket in the downpipe. That would affect your AFRs big time.

50 bucks for 2 bolts and a gasket? dayum

 

Comes with the rear gasket to!!!
