few people have done the conversions on R's & sr20's over the years.
if you have to buy the turbo & sort manifold then it quite expensive way to go when plenty of good easier options exist.
twin scroll is good for reduced lag & allows for good maifold design aiding good pressure distribution & scavenging effect..
I have a roller bearing titanium spec'd hta from an evo 5 that a spare feebie, to fit I want make a twinscroll runner paired manifold from scratch.
Was a company in canada & poland that done manifolds for the R for these turbos .
