I have a stock 1993 with pump mods and 366 spring. Will I be able to spin a hx40 with 4inch exhaust with my stock injectors. I want something i can grow into. I use the truck to daily drive and tow my 1983 dodge offroad rig total weight 15500 lbs

the turbo specs are
16cm3 housing
wastegated

Compressor wheel: 60mm in. x 85mm ex.
7 Blades

4 inch compressor inlet
3 inch compressor outlet

t3 flange
4 inch vband exhaust outlet

There are HX40's with T3 flanges that are not knockoffs.

I picked up mine for a lot less because it had an HX50 flange - between a T3 and T4.
Mine's 7 blade compressor and 60/62/17.

BUT I've got 6x.016 sticks. It lit pretty good w/stock sticks but really likes the new ones.

mine is a true holset and it is a t3 flange.

as for your engine spinning hx40, id think an hx35 would be better unless you plan on upgrading soon. these turbos are pretty big and take a decent amount to spool

You didn't look at my sig...

The 6x.016's provide plentyof fuel to spin the '40, and with the slip in the TC the engine revs nicely.
And the 5" exhaust gets rid of the back pressure also.

Anyone who is thinking about buying a turbo off ebay that isnt a real holset needs to watch this vid. Not knocking them but I dont wanna see anyone get hurt or hurt their truck. Watch the knock off go at 3:20..
