sorry i have been away i was river rafting the grand canyon<colorado river>..and spent some time in vegas...had a blast...im running RC engineering 440cc injectors with a VPC GCC set up and it handles 440 rear wheel perfectly with a supra tt pump....the stock tt injectors wont work on the 2jzge due to impedence and type of injector..i looked into that route also...if you want more than 440 rear wheel then add a couple more injectors on top of the 440cc injectors...toyomoto in miami can do anything you want for a sc300 or is300...let me know what more you need help on....
