has anybody looked into any holset turbo such as the hx35 to run?, Just curious i have a kb manifold tial wastegate and bov and think im gonna finish it out and buy the rest just wanna do it on a budget.
Any info would be appriciated

thanks!!

 

i have found the specs for a turbo made by holset off of i believe an 04.5 and above common rail that i feel i can get for a good price.

A/R- 0.65
Compressor inducer- 60mm
Compressor exducer- 84.582mm
Compressor trim- 54
Turbine inducer- 65mm
Turbine exducer- 58mm
Turbine trim- 80

the a/r is alittle small i feel but i plan on just running a mild set of injectors and a tune with it, any opinions?

thanks!

 

anybody?

 

People ask about holeset's every once in awhile, and never seem to end up running them. I dont know of anyone here running one. Most are sized for diesels and wont work too well on a gas truck setup. Just do yourself a favor and pick up a magnum or master power. The mp's are fairly plentiful used over on ls1tech.

 

as to what im finding your probably right, just thought i might get lucky, guess ill hunt for a different turbo

thanks!

 

I can tell you the Holsets especialy the HX/HY35s are becoming very popular for sportcompacts lately. They are cheap and large enough to make serious power on smaller motors. Upwards of 500 HP on a motor with good heads.

They do very well at what gasoline guys consider high boost, ie 20-25 +psi while having spool times that beat out other garrett based turbos of smaller sizes. They are also very tough units and cheap/easy to rebuild.

I still regret not grabbing one from work a while ago for my 2.5 mazda.


However for typical truck V8s it might not look as promising. The larger V8s if worked can knock out 500 HP N/A and the mid sized motors can probably do 350-400 relatively easily so the 35 series would probably become a restriction at the top end.

Also with the holset really shining in the high boost area typical domestic truck motors are not suited to run them with their less than ideal combustion chambers.

Even the newer LS hemi and 2 or 3 valve fords are more prone to certain issues than basic 4 valve motors from the same eras.

For the sub 5L motors though they might make a good affordable option. The 4.8 seems to take heavy boost relatively well but from what I have seen still not quite in the range of the holsets sweet spot.

There are larger holsets better suited to 5.0L+ V8s but without the abilty to work under high psi you would probably be disapointed in the performance at 10-15 psi compared to the more expensive units.
