Default does anyone know offhand the diameter of the 225 turbo charge side outlet? >

<center><img src="http://www.forgemotorsport.com/images/products/FM225TH.jpg"></center><p>
is it 2"OD (takes a 2" to 2-3/4" 90 deg hose), or is it larger, like 2-1/2" to 2-3/4"?

I need something like the hose in the pic but longer, and 2"D on the turbo side; depending on what I do, the 2-3/4" charge pipe side could work, or I could make a 2-1/4" happen too.

Help's appreciated - tia!

Default just looking at Hose Techniques available sizes, looks like I'm s.o.l. >

the 225 charge pipe is 2-3/4" inlet and my turbo is 2"; they don't offer one in those sizes so I guess the 225 is 2-1/4"...
Which means I need basically fab up a 225 charge pipe with a 2-1/4" or 2-1/2" inlet size OD. No big deal, just welding where there might have been none - was hoping I could end up just transitioning right to a 225 unmodified charge pipe.<ul><li><a href="http://www.hosetechniques.com/products/index.php?main_page=product_info&amp;cPath=204&amp ;products_id=2818">Hose Techniques</a></li></ul>

Default I got it worked out, thx though. >

got the 4.3" legs x 2" to 2-1/4" transition on the way; that'll work fine, standard 180 fitment.

Default well, my original question was, "was the 225 outlet D the same as the 180?"

not having the answer at the time I went on and ordered what I knew was correct, and I'll make adjustments elsewhere in the charge line.
