I think the compressor to turbine sizing on these (69/73) is a better match for the power I'm trying to make compared to the old Turbonetics (7268) and the wheel design is some of the latest out there. Quite a bit of size increase in both housings as well. Hope to make around 200 more whp.

Finally, someone getting the SXE369's that we will see some results from! I have seen a lot of talk and posts of people buying them, but no results. After I max out my cast 366's I wanted to upgrade to those as well eventually.

You have had some great info in this thread and it was an amazing build. Thank you for sharing.

You need to change the title of the thread from "The Quest for 7's" to "Been there, done that!"

The radiator hose is a used Nascar piece purchased from Ebay for $30.
Is the LJMS cam still for sale?

How did you make out with swapping to the Borg 69's?

They are working well. Feels stronger. I have been traveling south and racing some no time events and really enjoying it. They kinda frown on posting et's so for now I am not.

Great. Good luck with the racing. I guess we will just have to wait until winter to hear the outcome.

Can you take a pic of this. I would like to see how they are set up if possible. Thanks.

did you stay with the ls front disk brakes with the new front sub or did you change those also? If ls brakes still whats the spec on your front wheel to clear them? Thanks

Love the combo....really thought through

Can you give me an idea what the timing curve looks like ?

From peak tq up through 7500+rpm (9# launch to 36#)

I understand all combos will want their own "sweet spot"...just interested in the dynamics of what makes your combo pump out great power and durability.

Thanks for the great build.

Whatever it was I'm sure there will be some refinements made after this past weekend! Video looked hairy for sure but at least he kept it off the wall.

New turbos are here! Borg S369 SX-E's. Took them to the bandsaw right away and vbanded the turbine housings. So much easier to work with. Thanks to TurboSource out of Andover MN for the hookup on these.
