Engine/Transmission (1994 - 1998) turbine housing

[Jdimig]

hey everyone im thinking about getting a new exhaust housing for a HX35 and i've seen lot of different housings that are made for the HX35 but im a little in the dark about which ones are better than others. also is it better to go to a non-wastgated housing vs. a housing that is? im also thinking about the future where i like to be over 350 hp, and should i be looking for a HX40 by then? if anyone knows some stuff on housings plase let me know! thanks ya all!

If I were you I would start out with a 16 cm2 non wastgateed housings. It is a good turbine housing to start out with. I know that the housing is beyond its effency range for me, but I still run one on my truck which dynoed at 420 RWHP There isn't any room in the budget for a larger turbo right now and the HX35/16 seems to be doing the job just fine right now.



Look in the TDR classifieds for a used housing. I have picked up a few for people I know and I paid anywhere from $50-75 for one. If you don't see one listed, post a wanted add, that is usually how I have gotten mine. There is no use paying $125 for a new one when the only difference is that it isn't rusted yet.

I agree with Stroker Smoker.

I have the 16cm non waste gated and am prolly close to 450hp now. It should be a HX40 but it works good as is and the budget doesnt allow a HX40, new exhaust system and new exhaust brake which is what would be required to change over.

The choice of housings and turbos depends on where you want you truck to end up and yes the money issue. For some reason the budget always comes into play whe new toys for the truck is addressed.

A couple of months ago I went from a #11 plate and stock gov. springs to a #10 plate and 3k gov. springs. I am running the stock 215 injectors which has 211k on them. When I changed the plate and springs... I loved the way the turbo spooled but I had an idea that the EGTs and a certain hill just outside of SLO Ca. would get warm with the 14cm non gated housing. And since I was installing a US Gear D-cellarator(sp?) I needed to cut the exhaust. . I decided to replace the 14 with a 16 housing. This housing worked great. . on the smaller hills and up to 4% grades.

But on the way home with out 10k 5er in tow. . it was time for the test. . This hill I am talking about is 6-7% for 2-3 miles. I found out real quick that I WAS NOT going to be able to use all the ponies sitting under the hood. The boost went to 30lbs and the throttle had to be played with to keep the EGT's @ 1250. I know that I had a huge amount of air under the pedal but the EGT's could not handle it. I still went over the top @ 55 which is very respectable.

If you dont pull heavy and thru the mountains. . the 16 cm housing will make a huge difference. I was able to watch the EGT's drop after the would spike with this housing. Some adjustments were made to the no boost screw to help tune out the lag on the bottom end...

All in all its not a bad combination... but I know that if I were to add injectors into the mix... things would get real hot real quick...

Anyway this is what I just found out this past weekend with my current setup...

You will find if you dont already know... the 16cm housing is shorter than the stock housing...

Shorter in which direction? from turbo to manifold? to the down pipe?

Also how much shorter? and does it make much difference?

Its the exhaust outlet thats actually a couple of inches shorter. And yes unfortunatly it does make a difference makes it a ***** to install. What we have found its normally just enough difference to make you have to unbolt the exhaust and knock it forward some. Hope this helps
