now the CKO-40..... the purchaser must be aware that this turbo is not a direct fit-bolt on and requires mods as well to work..and that there is no support available to do so..
1# down-pipe: a person must source out the pieces to build the adapter(90* elbow,2 v-clamp flanges, and one v-clamp, welder) to attach the turbo to a gm down pipe(buddy has already built one and if he chooses may post the pics here)
2# oil supply: the boss on the turbo either needs to have an adapter sourced, or be re-threaded, to accept the gm-x adapter.
3# intake: i am not sure if there is modify/trimming involved, all we can say is that to use the H1C non-gated turbo on our build, there was a fair bit of trimming grinding needed to the cool-side outlet to slip a coupler over it as it was set-up for a holset elbow to go to an intercooler....
4# oil drain: i am not sure if the oil drain needs to be modified in any way to mount the CKO, although with our H1C we had to cut it and use a coupler for it to work... and i do not find any info with RZ's install in that department...5# flange to flange mounting: the CKO( depending on where/who it is sourced through) is a t-3 flange, but i have seen them with the t-4 as well...
These are my posts from the turbo upgrade thread on The diesel Place which starts on page three:
These are pics of the turbo mocked up on the manifold.
To install this turbo you will need to trim 1/2'' off the turbo and 1/4'' off the GM upper intake. I know in the pics it's close but what you see in the pics are not the measurements above. There will be enough room for expansion if you follow those measurements.
You will also have to make a 1/2'' spacer to put between the upper and lower manifold. Unless you would prefer to cut the upper futher back and use silicone hose to make up the height difference.
The oil feed line will need to be tapped for the GM oil feed line fitting, and the oil return requires no mods at all, it's a direct bolt up.
And continues on for a few more pages. Also the vids start on page 13 from the stock chip all the way up to tune 5 on the six banger chip.
after watching videos of the 2 different turbos, i can say that I do not see much difference in the over-all performance of the 2, although i will say that the CKO-40 is not recommended by me for a motor that is not built to handle 18-30psi boost, and is a waste of time to use below 15psi. the ATT is offered for both modified and stock motors, and boosts according to the amount of fuel available and thats it. in our opinion, we are more likely to stick with the non-gated turbos as we have enjoyed great results with our H1C(very comparable to a ATT i would guess) anyways we are not trying to start an emotional debate here, just stating what we have seen/heard to help keep everyone better informed... thanks, jeff&jim
Now you have your right to your opinions, as do I and will set the record straight.
1) What vids were you watching? Are you blind or just biased? The ATT is a chinese made knock off, the same as the one I run.
2) When did the ATT start being offered in two different configurations that makes it a dual purpose turbo? Modified and stock motors?? HUH???
3) The turbo I'm running
will work on both stock and modified motors and builds boost at a lower RPM then the ATT. And the hx40 will, like any turbo, only boost according to the amount of fuel available.
4) Why would the HX 40 be a waste of time below 15lbs.??? That is were it performs better than an ATT and spools faster than the ATT. It also spools as fast as a GM8 turbo. The vids don't lie and I think you watched them.
I even posted the use of the HX40 with the stock programming and it pulls to 3,500 rpm before the defuel cuts in. That my friend is proof enough that this turbo is better than any GMX turbo up top and stills spools the same as a gmx down low, and I won't get into the comparisons of any others to avoid a petty squabble.
As far as you not liking knock off turbos, that's your opinion and right. The ATT is from the same communist country as the HX40 is. Anyone, including you should have an open mind and if you don't like knock offs that's cool, but someone who see's the vids and reads the install posts and wants the same turbo but hates K/Os can get a name brand turbo in the same configuration or find one that is close to those specs.
If you want to continue bashing the clones that's fine,do you hate all chinese clones or just the one I use? The real reason I bought that turbo was that it is a less expensive alternative than paying full price for a name brand turbo, or paying the mark up of the ATT which isn't what I wanted in the first place, as it didn't fit the needs of my usage and I was buying a turbo for testing purposes to prove that there are alternatives that can work on the 6.5 other than the non-wastegated turbos out there.
Wastegated turbos spool faster down low and have less recovery time between shifts on a standard trans and that's a fact
and one of the reasons I went the route I did.
As far as you saying that I wired my wastegate shut and saying why bother running a gated turbo, the only reason I unhooked the hose to the W/G [I never ran it wired shut] was to see why I wasn't boosting as high as I had it set for and thought the intercooler was to big or there was a leak somewhere. After finding that there was no leak and that the wastegate spring had relaxed, I readjusted it and have had no furthers issues.
ALL THIS IS IN THE TURBO UPGRADE THREAD and was posted. You either didn't read it or chose to not read it all. In the future please get your facts straight, or don't quote what you haven't read or don't remember.
I would be happy to help you by listing any posts I have made and which page and post they are in the future so as not to put out any misinformation.
After all isn't sharing and getting the truth out while helping others what this is all about??
Just let me have the same oppertunities as others to share what I have done so others can make up their own minds without bias or personal attacks on said modifications.
We all have different wants and needs out of our trucks and NO ONE TURBO CAN MEET ALL NEEDS OF ALL TRUCKS OR INTENDED USES.
we are not trying to start an emotional debate here, just stating what we have seen/heard to help keep everyone better informed... thanks, jeff&jim
That's all I'm doing also.
Please don't take this post out of context as I'm not looking for any trouble with anyone. PERIOD.
I've stayed off this site for awhile. I'm just pointing out some facts and some opinions as others have, please lets keep it civil with no name calling or other inuendos.:thumbsup:
