wondering if anybody as ran into issues while putting a HX35W on a first gen. The wastegate housing is hitting the coolant line coming from the oil cooler. I know I will have to get a different oil supply line for the turbo, one with 2 90's in it.

What year HX35? Is it the one with the wastegate actuator mounted on the compressor?
Also what year truck? Mine is a 1990 and I can't think of a coolant line from the oil cooler. I don't know about the later trucks though.
If you could post a picture I would help.

the year I have no idea on the turbo. It does have the wastegate on the side on the compressor. It's a 1992 dodge W250 with an auto. I'm thinking of just running a heater hose and taking off the hard pipe that's on it from the oil cooler to the water pump. Just wanted to see if that's smart or not so much

As long as the hose is a good heavy duty hose I don't see any problem.

This is kinda hard to read but may help ID your turbo.

The guy I got it from, who's the boss of the bosses, said this was on a 800 hp cummins for less than 2000 miles but it wasn't pushing hard enough for him so he changed turbos. Got it for free.....well I have to wire his barn but that's a good trade off lol. It's got the 14cm turbine housing on it. Don't know how much boost it'll push but I'll have to keep it under 35 lbs

Thanks for your advice mark. I appreciate it greatly

If it has a 14cm housing, it's probably not an HX35W. It could have been changed, yes, but that, coupled with the fact that it is interfering with your cooler, makes me think it isn't an HX35W.

I have never heard of ANY interference problems with stock parts when installing an HX35W on a 1st gen.

Post some pics of your turbo so we can see what you have.

Also, there was no way an HX35 would be on an 800 HP engine unless it was in a set of compounds. Even then, it would be a BIG stretch.

Their are numerous variations of the HX35W turbo. I have not ran into an interference issue with any of them I have installed. The oil cooler you are referring to is the transmission heat exchanger. It's used in the exact same position on the 2nd gen trucks that came factory equipped with the HX35W.

You can buy a different exhaust housing that would move the wastegate to a different position that would not interfere with your heat exchanger.

Well that's what the tag on the face of the compressor says. HX35W. It could be a 40 turbo with a 35 compressor housing on it...maybe.

I thought the tranny cooled was located in front of the air to air, on top of the a/c condenser.

It's not interfering with the cooler itself, just the hard pipe that goes from the WP to the cooler.

Red, how much boost does a HX35W put out?

Their is more than one transmission cooler on the truck, so yes their also is one up front. The one at the side of the block also assists in heating the trans oil in the winter or cold weather to speed up the warming process.

A turbo by itself doesn't have a specific boost output. Their are numerous variables that determine what a turbocharger produces. I would suggest reading up here on this site on the basics as to how a turbocharger works, it may help you in keeping your engine from doing something you don't want it to do.

What is your elevation?

Cactus92

Oh I know what a turbo does and how it works but I'll still check it out. Went to college for diesel mechanics but only worked on trucks and put factory parts back on. Never modded

Cactus92

Ohh we are right around 2030 in elevation

Fuel plays a big part in how a turbo acts. My baby H1c will hit 30 PSI but everything has to be just right and you really have to be watching the gauge to catch it. It would only hit maybe 15-18 PSI before I turned up the injection pump a bit.

Cactus92

Oh that it surely does. I've got it turned up a 1/4 of a turn on everything. 75-100 hp injectors BHAF 3200 spring and fuel pin. 4" turbo back exhaust. I'm thinking I've got the engine breathing awfully good
