Ok guys and girls, i have a few questions.... i recently dropped in an RB30ET into my skyline 1. is there a difference between the regulators? 2. i'm using an auto turbo computer to run my 5 spd, will this cause any problems?? 3. it started fine after first dropping it in and ran fine around town, but when i got it on the freeway, the temp crept up, and i think that i've either down a head gasket or head. what do u think would've caused this?? tested thermostat and works fine. I'm thinking possibly the waterpump??? 4. i've got a recoed head to put on anyway, ported and polished with AVO stage 3 cam. What sort of difference will this make with the turbo? 5. how hard is it to replace the rubber hoses connecting the injectors to the fuel rail? 6. with the turbo, doesn't seem to pull over 4-4500 revs. does this seem right? thought that it could have something to do with lack of fuel??? Auto comp?? Fuel reg??? Sorry about all the questions, but your help will be greatly appreciated. Benji
