Glad your ok Al. The Buschur solution is at the top of my shopping list. Now, if I can just get 2/3 of my income back, all will be good.

I keep preaching about parts for daily drivers vs race cars... reflashes, fuel pumps, larger injectors, exhaust manifolds... a quality cast piece will always out last a quality tubular piece in the long day in and day out haul.

PS for the guy who thinks the rest of the country is as jacked up as CA... you need to get out and explore the rest of the world. Most of the rest of the country can still enjoy our cars legally.

Last I checked, the HKS kit has no turbo support bracket that bears the weight of the turbo. Instead, it relies on a combination of the manifold and the downpipe to hold it in place. Gravity being the b#$tch it is, the manifold will take most of the beating. Add to the fact that there probably wasn't a flex joint in the downpipe and that the HKS manifold is made of very thin guage material and a stress-induced crack is bound to occur. Cracking is not an inevitable outcome with a properly constructive tubular manifold. It's just that most people doing want to pay what it takes to make a proper manifold. Look in the profressional racing (no, not 1/4 mile straight-line stuff) world for hints on how to build a proper and durable tubular turbo manifold.

Just my 2c,
Shiv

Actually Shiv - I had Pruven install a flex section in the down pipe as I saw that this manifold had a lot of weight on it

Also - it does have a little stay bracket



Team Pruven is on the job as I type making up some stay brackets and putting some pacthes over the crackes areas to get it rolling till the Buschur kit comes out

SFP - thanks for the kind offer - but I think I will just sell the set up and go with the Buschur set up - it will make more hp and will be stronger and cheaper

ya know what? you should start to mod yourself!
install a carbon monoxide detector in similar fashion to a pace-maker or something.

Ok that was silly. Bottom line is glad your ok AL.
Is there any treatment for this kinda exposure?
Like some kinda detox session?

First off you can run tubular manifolds very successfully on daily drivers. They must be built correctly in order to last. There are a lot of tricks of the trade that we use to build our manifolds. Like I have said before we have been building them for a long and time and have never had one come back.



We use cast runners for ultimate strength. The runners are 1/8 thick. This is real thick 8 gauge and will not crack.



Also if some small pieces of metal falls through your turbo it isn't going to break anything.


We tap EGT ports all the time on the car with it running, without any problems.



You would have to have a big piece of metal go through there to be a problem. If there is that mush slag on the inside then they shouldn't be building manifolds anyway.

Al does the HKS turbo kit come with a down pipe? I thought it did.

I do not think that I want any metal flakes going through my engine no matter how small. If those pieces of metal make way to the cumbustion chamber I would think that the high heat could cause some fusing togather problems couldn't it?

They wouldn't enter the combustion chamber...thats the other side of the turbo. On the otherhand...It seems no matter how much anyone argues... David Buschur called it. He stated these manifolds would fail...and they did.

I also believed the HKS manifolds would fail. You can't use thin gauge material to build a turbo manifold. You must use thick gauge if you want it to last.



We have enver had one of our manifolds come back for a repair. We know how to build them right and they don't crack.


It's all about who builds the manifold. The design, material and welding techniques play a huge role.


We beleive we have pretty mush mastered the skill of build a tubular manifold that will last. One of the key features is our cast runners.

I presume you mean that BR's kit will make more HP than the GT3037 kit. I'm not sure how you mean it would be cheaper though. Or were you refering to his kit being cheaper and making more power than ours? It just struck me odd that he hasn't released a kit yet.

Thanks to Patrick at HKS USA! The situation is resolved to my satisfaction. Which I greatly appreciate. I will report more early next week as nothing is going to happen till next week due to the holiday.

I haven't released the kit yet because the first two manifolds from the casting plant came in a week or so ago. They are now being CNC machined to make sure they fit up correctly.

Al was saying he is going to wait for our kit because it will make more power than the HKS 3037 kit. It is also going to be half the price of the HKS kit. Our kit looks like it is going to come in at under $2500. The kit will include the turbo, manifold, tubular 02 housing, oil feed, oil return and any needed bolts.

I have nothing else to say about tubular manifolds. I guess all the retarded people that I have met over the last 15 years just couldn't get it right.

wow, under $2500 sounds awesome.... look forward to seeing more on this....

I have no itnention to sue anyone. These things happen from time time - especially under hard use.

My main concern was having this happen so qucikly on a piece that is so darn costly.

I think I may have jumped the gun a bit assuming a nightmarish ordeal trying to get warranty support from HKS USA.

I was pleasantly suprized - and while I am still feeling sick, had to rent a car for a few days and obviously had to do some work on the car to take this unit out - - I AM SATISFIED with the solution offered by HKS USA and I am going to work with them to get his resolved

I have had good experience with the HKS 3037s turbo set up untill this point and I hope it was just an isolated failure

I am going to get the carbon monixide detector in my car and give it another shot with a new manifold
