I saw them on ebay for the first time today also but i would rather the adz ubend.
I think they cost a bit more but they are 85mm and you can port them out a bit more

Yeah, the Adz unit is nice but means I would need to upgrade to an LS TB, I really wanna keep cruise control too.

I'm not interested running much more than 10-12psi with possibly a cam or rockers, blower spacer and regular bolt on mods. Not intending to run tiny pulleys with IC systems etc. This is my missus daily driver and reliability is paramount with fun factor coming a close 2nd :) If I stick with he 69mm TB the larger Adz elbow is probably a waste?

You can keep cruise control with the ls throttle body, im running a 75mm stock ls1 throttle body with cruise control.

Yeah if you are not planing on lots of mods it likely not worth getting the adz one but inless you want to port the blower you will not use this one to the full potential either.

You might be better off porting the stock ubend to accept an ls1 throttle body.

Will definitely port the blower at some time.

Planning on taking it to work one day and milling out the bottom. What I actually need is some pics of a M90 with the intake side ported.

edit: stock elbow really is a poor shape.

I think OZ38 has some good pictures.

Would still recommend a ls1 throttle if younare going to be porting the blower.

My mate fitted one up this week and is happy with the improvements, been in a VS the firewall did need some massaging to make it fit.

Planning on doing some before/after runs with my data-logger and try to put some numbers on it.

I have some pics on how to gain 200cfm of inlet flow but it requires cutting and welding of the case :-P
