that fact came from a person with little to no experiences with any turbos. im accually LOL from that comment.

as for the question, from my gatherings, many people are using holsets on gas engines and having absoutly nothing but positive feedback from them. I havent heard much negative info from them. Check out my holset thread.

This is also why I usually stick to the Tech section.

Honestly I don't have to answer the same questions over and over again, maybe because I give in-depth help and information instead of snide comments. People and forums in general seem to respond more to a helpful atmosphere than a condescending one. Consider this...you were a noob once too, and I'm sure you used to ask some pretty idiotic questions. Hell, you still use afc's and btm's...time to catch up a little, bro. But if knowledge scares you, stick with what you know.

As for diesel turbo's, I've used the KKK models from mercedes turbo-diesels, as well as VW ones as well. They seem to work ok, although suffering from smaller exhaust a/r's for quick boost response on diesel setups that usually never make it above 4500 rpm.

Yeah. Problem with diesel turbo - their small turbines. Just find out big enough diesel turbo and it will work just fine.

Some of the old GMR alloy turbines won't hold up on a modern turbo charged gas engine thats pushed to the limits. GMR alloys have a thermal limit thats about 150 degrees less than Inconel. If you aren't too aggressive It will hold hold up. You really want a Inconel or titanium alluminide alloy or a silicon nitride turbine.

Most turbo makers switched to Inconel for a majority of the turbine wheels they made but they still used the GMR alloy on some diesel turbochargers for a while to keep cost down.

Well, it'S certainly not garrett'S case. on their diesel turbos, they use the same exact alloys as on performance turbos. And they're the same trim wheels and part numbers too. For example, since the mid 60's until now, you see on trucks, tractors, generators, compressors and farm equipment the same exact T4 O, N and P trim turbine wheels as seen on their performance turbos. internals are also the same. ACtually BETTER than for most gas automotive turbos because all diesel turbos have dynamic seal system while cars like the nissan 60 trim Z31 have static seal which is inferior.

Once, i used a Holset 3Ld from a industrial snowblower, on a H22.
It was brand new and it blew in 4 days.
FLakes were coming off the turbine housing. at first sight it may look like weak alloys and overall quality of the turbo but i know it wasn'T the case. THe real reason for such failure was that the 3Ld was too small for a h22. spooling super fast, choking the engine up top and Causing enough restriction to make manif and turbine become glowing red while it was overspinning, which abuse would have destroyed any turbo of course.

i think thats why my car smokes after boosting. i have a really small turbo. as long as it stays in vaccume the car doesnt smoke, but after a run with boost it smokes for a min. or two. hopefully with this t3 i have all of that will be gone

wow what did you think was going to happen?? thats like putting a 14b on a 5.0 and being supprised that it blows, and calling it a crappy turbo,

i dont care what all of these ------- noobs are say'n i have seen tons of diesel turbo's on hondas and nissan's and ran absolutely fine, anyone who differs is a horse's *** !
