Stanton you can get a early inlet converted , they blank off the oe throttle body side , fit the throttle body the other side and do the same with the icv .
You do have to relocate the alternator and extend a few wires ect as well , but it can be up n running for under £500 [emoji6]
The phase 1 inlet set up has a snorkel on the turbo (hence why early tdo's have to be converted to front entry) so the intake pipe doesn't have to run under the manifold
Thats a pic of my brvs v1 sti when he first got it I'll try to find a better pic
