Brandon's post with all the turbo info in it should be sticked ... if we could couple the info he's got with the following:

1. Exhaust housing info (volumetric size)
2. Exhaust housing clamping style (v-band vs. etc)
3. Pipe size (3" or 4")
4. intake wheel diameter

etc ...

great post - btw

 

he351 has a 9 cm housing.

 

Did you make or buy the 4" DP?

This could help some. Courtesy of: http://dodgeram.org/tech/dsl/FAQ/turbo_faq.htm. There's a lot of other good info there too. Even more info here: http://dodgeram.org/tech/dsl/Facts/01ISBspecs.html

All of the above turbos have a 3" outlet from the turbine housing. 3rd gens started the 4" outlets.

I didn't see a chart with any similar info for the 3rd gens, '03 and up. Yet, I'm sure it could be found easily.

 

Come on, you ought to know better than that.

They probably meant factory max boost?

 

What are you talkin' about?! I don't see anything in my post . I think you added that!

Not sure they would've meant max factory boost since the max boost range is the first on the list. Who knows. Can't believe everything you read on internet, right? I proved that already

 

I thought 93 5 spds had 21cm exhaust housings??? Im not sure tho.

 

Nope, 18.5

 

Nope. '93s, regardless of transmission, reverted back to the 18.5cm housing. Same with early to mid-'92s, regardless of transmission, they got the 21cm housing.

Edit: I was too slow!

 

If I have a 18, Id hate to see a 21.....UUUGGGHHH!!!
I really thought I had a 21.... thanks for even more knowledge!!!

 

Exactly why they were appropriately named "The Lagmaster"

 

Yea I got the lagmaster lol I would love to even have an 18 just that little bit would be enough to make me happy.... for awhile

 

FWIW my 91.5 had a 18.5 housing and it lagged way too much for me.

 

My 91.5 has the 18 also.
