I have an 18rgeu and am in the middle of planing the build. So far here is what Have planned.
stock efi intake/injectors
SDS management-EM-5 E/MSD
Questions on some Ideas I have...
supra throttle body
which toyota injectors?
Air to air front mount or air to water intercooler?
I am thinking that I will have a friend water jet the exhaust flange using a TRD header for measurements then buying one of the turbo manifold kits available off the shelf. Im also wondering which motor; 4ag, 3sge etc has the most similar distance between the exhaust ports so I can put the turbo manifold kit on the jetted flange for the 18rg.
