Exactly what I was thinking, keep the original connections on the injecter carriers and cut either side
Here's some low spec ghetto drawings
Cut on dotted lines
Here's what you left with
Get some alloy/steel tubing snug enough to fit over original fuel rail tube
Place everything lose into inlet Mani and adjust for fitment
Tack into place and voila!!
Leave fpr connection where it is as you can use the adapter either way as sr20 and cg have same spacing and size
One rail with correct spacing
Then use either cg or sr fuel in tube and weld to fit
Cut mounts of and weld into position
I could cut everything in around 30 mins at guess with say a dremel
Cut tube to size slot over ends and weld into place,
To actually tack into position I can't see being to hard
It's just time consuming bro
Hope your well matey
