What is the difference between these two Turbos? I know that the hx35 has been in like 95+ models. What is the benefit of upgrding my stock 1992. 5 to a HX35? I plan on changing the fuel pump and timing, possibly injectors too. Getting a used hx35 and 12cm2 wastgated turbo seems like it might be a good modest upgrade... .



I have been getting mixed advice about what housing to use... a friend says to just get a wastegated 12cm2, others say a 16cm. If the 12cm2 works for the newer cummins engines which have more horsepower, why not for the older ones?



My friend also talked about ordering the injectors for a stock 89-91 motor non-intercooled andusing them as a moderate upgrade. I know they are 9mm and mine are 7mm, but he says he can use the old sleeve or something.





This is my first diesel and I really like it.
 
sorry, gotta update my sig...



1992. 5 4x4 with 75k miles, auto, pull loads of less than 7,000lbs and do about 90% of the time unloaded.

The non intercooled trucks(89-91) have 9mm injectors, the 91+'s have the 7mm, so there's no way to use the old injectors in a newer truck unless you switch the cylinder head...
