old topic i know
but just thought id add in that yes, EFI 18RG parts are hard to come by.
Just bought a EFI manifold, EFI thermostat housing, stock ECU and the injector wiring loom, and it cost a pretty penny. also got a 18RG turbo manifold and a T25 on it. this celica is gunna get up and go
Btw, a 18RG on twins is quicker, and the induction noise is awesome
The 18RG i got has flat top pistons with a lower compression, going to run it on solex twins to iron out the bugs, then slap EFI and turbo on, and boost the biatch!!!
