August 4, 200520 yr hmm maybe i will try myx's flowed injector rating on my rx's fuel table and see how well it likes it .. i have mine set for 80 cc a min on my megasquirt setup and it seems to run pretty good for a tired old motor edit: my one key is borked .. so make that one eighty cc's
August 5, 200520 yr some guy in new zealand fitted 1983 jaguar xj6 injectors into his rx.they fit straight in with a change of o-ring.possum Borne used these in his rx rally car in the day.
August 30, 200520 yr Just got mine back from RC. Injectors from an 88 RX. #1 and #3 might be switched, but #2 and #4 are the correct cylinders.
August 31, 200520 yr btw according to a fuel psi conversion utiliity for one of my megasquirt tuneing programs 240 cc/min at 43psi converts to 219 cc/min at 36 stock suby psi now i assume the 36 psi we are supposed to get is only at idle ect or is that the max full boost fuel psi the regulator provides? since that might be useful to know

The regulator is setup to deliver a steady 36(point something) PSI above manifold pressure. ergo, at 10 psi of boost, you should be seeing 46psi at the injectors
August 31, 200520 yr The Subaru regulators should be 36psi at atmospheric. Under vacuum the pressure should drop, and conversely rise under boost. I still have my megasquirt set to 185, although 219 would be the proper number given the test results as Clayton said. A regulator from a 42psi car would be an upgrade in addition to fuel management, giving you the maximum from the stock injectors.
August 31, 200520 yr wel if i tell ms my injectors are much bigger than 200 cc then it starts to bog down even at idle and this is with stock xt spider non turbo injectors on a turbo rx.. so go figure

September 8, 200520 yr Author Just got mine back from RC. Injectors from an 88 RX. #1 and #3 might be switched, but #2 and #4 are the correct cylinders. Off of what car, year, model are these injector flow rates in reference too?
October 20, 200520 yr So I got my RX injectors back from RC engineering. The results were good. Interesting to look at the before and after picture you can see the cleaned on the right. The gap is wider, and they all came back a different color? wierd off my donor engine never actually ran in my rx: before/ after 221--Dripping/ 238 exc 230--good /240-exc 235--good /242-exc 1 with electrical damage replaced with injector from car 220--good /240-exc Interesting how the one that was actually on my car, had a good spray pattern but, the worst cc/min
