*PUTS ON THE BRAKES TO A SNOW BALL THREAD*
In general, a turbo is a turbo is a turbo. There aren't only two major differences between why a diesel turbo can't be used on a gas setup.
Carbon seal VS dynamic seal.
All of the large garrett, holset, kkk, borg warner etc use diesel technology.
The GT42, GT45, GT40 turbos? Started out life as a diesel application.
57 trim Garrett wheel? You guessed it. Diesel application.
A carbon seal turbo has to be used on a blow through or draw (suck) through gas application.
A dynamic seal turbo can be used on any thing fuel injected.
Most turbos on the road today, performance or OEM are dynamic seal turbos.
Now that we have that out of the way -
-The power stroke turbos are a no no. They either have the wrong (backwards) housings on them or have too large of exhaust housings. The new ones are also variable vein. These are also a no no.
-Duramax turbos. Again, a no no due to variable vein.
-Isuzu NPR, or NP series turbos are hit & miss. Some of them are small, some are large. Most are non ball bearing GT series
-Volvo. Again, hit or miss. Some are holset, some are GT35's.
-Diesel turbos in general are hit and miss. Most have GIANT rear housings on them. If you can find the old TA45/51, GT40 series, or the TV81 series and have a custom rear housing installed on the exhaust side, you're golden.
-The IHI Gm8 turbos are a decent upgrade for our stock 7m's. The problem lies in the fact that cost of fabricating one to a manifold VS 57 trim upgrade or bolt on is about the same
-The Holset hx35, hx40 and hy35 are awesome turbos for our cars when used with the 9cm or 12cm rear housings. The problem with these turbos is wastegate controll. The internal gates are WAY WAY too small for how fast these turbos spool and react. The only way to go is to port the wastegate hole out or run external. The little hy35 is good to 450/475 hp. They can be found on alot of the dodge ram pickup trucks.
Any more questions, you can direct them my way.
