Does anybody have any experience using a 14cm non wastegated housing on an HX35? I'm considering going this route because it is way cheaper than a wastegated housing and I really would like to drop my egt's while towing on big hills. I have the edge boost fooler elbow on my turbo right now and that pretty much blocks off the wastegate but I don't know if going with a housing that doesn't have a wastegate at all will be a mistake. Also, I don't really want to go to a different turbo because of my exhaust brake. Please comment if you have experience with this. Thanks, Eric

 

I tried a non wastegated 14 on my 12 valve and ended up going to a wastegated one.
Boost went way higher than the 35 psi I desired, was afraid I was going to toast the turbo.
My opinion is that you need at least a 16 cm before you can skip the wastegate but then you suffer slow spool up.

 

I'm with Bill on this one. But by the time you get the 14 cm WG housing, you are nearly halfway to a better turbo. PDR sells a B-1 type turbo with an HX-35 outlet, you might condsider that instead.

 

Either leave the stock 12cm housing, or get a better turbo. I went down that road, and that is my .02

I am looking for one.. I already have a wastegate..

 

I am really satisfied with the performance of the 16cm non waste I have on mine, As far as slow spool up I noticed a slight difference but after the 4in exhaust install it helped put the spooling back almost to the 12, where it shines is pulling our trailers as egt's are a concern. I use my trucks for pulling trailers and such not romping them around so that is where the 16 non will help allot. Goodluck,,Rick

 

For a 5spd, the 16cm housing is probably a little better. Its just hard taking off with a load with a tight converter, and the bigger housing. Once it spools, its fine; but it can take a minute to spool depending on your converter.

The problem with high EGTs isn't *just* the tight housing.


It's the fact that the turbine side itself is pretty restrictive.

Better to look at a larger turbo than just a 14 ng housing.

12wg is a better option than 14ng IMO for EGT control AND spoolup....
