Its a Copy of a Holset HX40w.... its about 1/4 the money of a new Holset....Hard to tell what you will get for your money. I just kept looking at used Turbo's on Ebay until I found a True Holset HX40w for 150.00 and I got a rebuild kit for 35.00 and rebuilt it myself. Still cost me less than a Copy...

 

i know it is a copy, but the question is...will it be a good uprade to the ats093

 

Think of it this way... your 093 was designed to be fit on an engine pushing 444 cubic inches of exhaust and demanding the same amount of supply for intake. The Holset is designed to go on an engine topping out at 360 cubic inches. Therefore, the 093 is a better turbo for your engine because it will spool and supply your engine better.

If you want more power, go get a Powerstroke. Otherwise, be happy with a turbo on your IDI. There's really not much more you can do to it other than major surgery and insane amounts of money for a 20% power gain.

 

The short answer is no. The copy turbos are junk and do not perform like the real thing. Those who have tried them have been disappointed with the result. I think your OEM Garrett will out perform those Holset knock-offs.

 

thanks for the input, i actually considered long and hard about a psd conversion and hit alot of the forums digging up info, this is what i have found, cost of psd with electronic crap to go with it 2k, injector upgrade with tuning ( just to get to 300rwhp 3k, so we are looking at around 5k minimum for a 300hp psd with well over 100k miles, now for my idiT, i own it so there is no cost, 450 to rering it, head studs,ip upgrade,cam and sticks 1500, if i wanna upgrade the turbo exhaust looking at about 200 bucks, and this will get me real close to 300 rwhp, with a much lower maint cost, in asking about the turbos i posted above, i was merely trying to figure out the best bang for my buck, while i have the idiT apart i will port and polish the heads, and put in a set of comp 910s,some new lifters and pushrods, and a new oil pump, all in all i will have no more than 3k in idi, and i believe it will be more reliable, more powerful, and cheaper to maintain than any of the powerstrokes

 

To actually reach 300 at the wheels you are going to need at least a 110cc injection pump, a larger and highly efficient turbo and an intercooler. 2.7 whp per cc of fuel is a decent guideline if you have efficient intercooled boost to burn the fuel. That said, IDI torque numbers are high for the hp and come on low in rpm's so the truck may feel more potent than the hp numbers would suggest.

 

The HX40w pushes a lot more air than the 093... It also needs more to spool it than the 093... The problem putting a Holset where the 093 sits is that the physical size difference makes it not hook up to the y pipe or the exhaust pipe.. or any of the Intake air pipes... If you are ready to do modifications to make it fit and fit under the hood it will perform very well if you have a 16cm2 t3 housing for the Hot side... Mine is a 18cm2 and with 90cc I spool pretty good. I think a 16cm2 would be better in a Truck application with the smaller exhaust pipe you will have to run just to fit under the hood. Mine is in a MH and I have wrapped up pipes and a blanket on my hot side with a 4" exhaust with no muffler and a 4" line to a 7" monster filter fed from a roof mounted air intake. 18PSI Boost after the Intercooler and I Have never gone over 1000EGTs WOT up hill for 5 Miles.. I think that is Dam good in My book...

 

Sounds great racer, and i am gonna be running the R&D 90 pump, looks like it throws 100cc till 2200 rpm if i am correct and i am going to use his hotside upgrade downpipe, i found an intercooler that i am thinking of using it is 3" in and out, core size is 24" x 12" x3", as long as it isnt restrictive i think it will work, since there never was an intercooled option something would be better than nothing, i realize im going to have a little more turbo lag using an intercooler hopefully i wont get hurt to bad

 

You wont feel any lag...The improved throttle response from the new Engine and more fuel will make you Happy and the Intercooler will Help control the EGT's Just make sure to seal the Intercooler to the front of the Rad to make the air pull through it...Also make air control panels to make all air forced through the grill to be forced to go through the rad Not around it... Adding a intercooler can reduce air flow through your rad so make sure to seal all around the shroud with rubber seal also to maximize its cooling... With extra fuel comes extra Heat...

 

I plan on doing some ducting to the front. I dont use the engine fan,and sometimes ideling for. Long time with the ac on she gets a little warm

 

Would a 7.3 power stroke inter cooler with R&D's 90cc pump, and his stage 2 turbo be "highly efficient" in your opinion?

 

Yes. That is a very good combination and is exactly what I bought for my build except I went with the 110cc pump. I recently talked with Justin and he said the 190cc pump, Stage 3 (S366) turbo on his stage 3 intercooled turbo kit was producing mid 30's psi of boost and the drive pressure was still less than the boost pressure, so it had not even reached the 1:1 pressure ratio at which point efficiency really starts to suffer. The S360/ stage 2 is plenty of turbo for 90cc's and should be very responsive. It is badically the same as when Justin had the A3000 on his truck with the 90cc... He said it was nicely optimized combo and a very potent truck which says a lot coming from someone who just downgraded from a DB4.

 

I Posted 300 Crank HP with 90cc is easy to get with some mods and a Good Turbo and Intercooler at 3000rpm. This Engine makes around 2.6 or 2.7 Wheel HP per cc of fuel using Data from several dyno runs across several different Trucks as Ford F834 has posted... I keep Forgetting you Guys are All Wheel HP Guys and I am A Crank HP Guy... To Get Crank HP you can multiply the wheel HP by 1.2 to 1.3 depending on the Running gear of the Truck... So I figure a Well tuned Truck running just 90 cc will produce between 234 or 243 Wheel HP or 280 to 315 Crank HP as an Estimate. Using this info again we can Estimate 343 to 386 Crank HP from 110cc based on as much info we can get from the guys that have had there trucks on Rollers. I wish I had Access to a Engine Dyno For my Next build It sure would be Cool to see the Numbers from the crank on a sweet Built IDI...
