just a quick question, I have a TVS1900 off a 2011 sierra 5.3 flex fuel. What other LS engines will it fit? Came off my dads truck, and looking for LS engine for an older car, but want to narrow my options to a engine this blower will bolt onto.

thanks alot

 

It will fit anything with cathedral heads. Also it needs to have the truck spacing on the accessories. That means the newest generation camaro accessories will work too.

 

You've been a great help! I couldn't remember when I put it on what the head ports where...and being lazy, i figured id
just ask!

What engines have cathedrals?

 

All the 4.8's, 5.3's and 5.7's do. The Gen III 6.0 do as well. That means the LQ4, LQ9, and the first year of the LS2 was kind of a hybrid believe it or not... Either way the LS2 has cathedral heads. The 5.7 never came in a truck so you would need to change the balancer to a truck balancer to line up right.

You could really put cathedral heads on any LSx block you wanted. The 1900 seems to be really happy on a 5.3 or 5.7 though letting you make real boost when you spin it up high!

 

Thanks a lot for the help. Think i'l try and find a nice gto pull out with a t56 for this blower

 

Does the 6.2 l92 2009 escalade work with this? Does it have catherderal port heads?

 

Nope, square port heads
