Does the T4 have more efficient flow than the standard uppipe setup for the 99.5-03 trucks?
I am counting the benefits, ebpv delete, turbo options and uppipes on my stock 02. Thanks in advance.

 

 

The style of mount doesn't mean as much as what's inside, 94.5-97/e99 trucks came with a T4 turbo. Turbine size and blade profile make the difference in flow. A drop in KC SXE turbine wheel in a stock SD turbo will do the most for flow in a stock turbo. True aftermarket T4 mount turbos (not stock T4) flow so much more than stock based on their LARGE turbine/compressor wheels.

The up pipes on the CSD T4 mount are so nearly the same as the OEM, that I think it would be hard to quantify the difference in flow.

 

The uppies in the T4 are just basically better design in that they are leak free for the most part.

John, LOL....good one. Just where is that lazy bazztard today anyways?

 

Lol..that fart smeller still wet'n his pants over the job well done

 

yall are brutal!

 

The T4 does NOT flow much more efficiently than the OEM, more on this later in the reply...

Yes, it is a great setup. Only slept until 10 this morning... So, well before afternoon.

This...

And this...

This too and I have started installing solar on the 5th wheel, which is a lot of effort, so I need my beauty sleep...

Fart smeller, here we go with that again... Don't you have a customer waiting for you right now?

Yes, yes they are... We have to keep them around though otherwise they would get bored and spend more money on their truck.

As for the T4, it does NOT flow a good deal more than the OEM up-pipes. It might flow a little better, but not by much. As for the tubes and pipes, where you make the difference is with new clamps, boots, fasteners and seals. Your older system has some leaks in it, no matter how small or insignificant one can be by itself, they add up.

The T4 up-pipes (from CSD anyway, I cannot speak for the Irate kit) are well made and welded well.

Brokestroke has the idea down. The biggest benefit of the T4 mount is that you can swap out the turbo for a far superior product that costs 50% less than what a drop in turbo performs or costs. The SXE is 20 years newer technology that has gone into the design of the turbo. That is the easiest way I can put it.

Not sure if you have seen the video on my install of the CSD T4 kit and the Borg Warner SXE turbo, so I will link it below.

 

Thanks, all.
Sous, I watched the vid and thats the problem! SXE sounds awesome but would love to keep the truck as stock as possible to piece it together slowly. KC's wheels sound like a good alternative to start with. Maybe he will have a 364.5 copy soon.Trying to get smart before dropping money.

Here is another problem for you. If you are limited to stock look because of state regulations concerning smog testing and what not, you have no options other than modifying the OEM turbo with a billet wheel, high flow outlet, etc... You can try and squeeze a Garrett GTP38R by the inspector, but you may be shooting yourself in the foot.

If you want to keep the truck as stock as possible, then you should NOT change anything and just drive it.

The products from KC turbo had a lot of hope and vision from the 7.3 community, but that has not panned out. If you are looking to upgrade your stock turbo with a KC exhaust wheel and KC billet wheel, then do that. I for one would NOT put a KC turbo in my truck due to hearing about high EGT's and mechanical failures from more than one person. I am not going to say any names, but they no longer install KC turbos due to the turbo failing.

Look at the SXE and T4 kit as a whole. It is nothing more than tubes, pipes and a turbo... That is it... So, if you are looking to get bellowed up-pipes, modify the stock turbo, do a pedestal delete, a performance wastegate, an intake, etc, then you should really consider a T4/SXE.

Why would you buy a copy or a product trying to imitate the real thing when you can just get the real thing and know that it will perform up to your expectations.

Trust me friend, I went through all of this over the course of many months and talking to many people. I talked to mechanics, tuners, customers, engineers, etc and I came to the conclusion I did because of their insight. I am not let down by my decision, but you have to make your own decisions. We would be interested to hear about your decision whichever way you go.

Ask questions, read, ask questions, read and keep doing what you are doing. The right choice for you will come to you. Maybe the OEM turbo is right for you, for me it was not.

 

Thanks to Sous, I am now wanting a T4/SXE for myself. I may have a bellowed uppipe/GTP38R with RR billet wheel setup for sale. Interested? (Mods, if this constitutes a forsale post please delete and accept my humble apologies.)

 

 

You did see the part of my sig that says "Bad case of PMS", didn't you?

 

 

Sounds like a set of dorman up pipes and save for the sxe! Picture from

when I dropped it off in storage.
