when i originally planned out the mod list for my mr2 it was nice and simple. a ct-27, intercooler, fcd, exhaust, possible intake, boost controller, and violla ive got a reliable set up for 250 whp. some how now ive got 10 different mods pulling me 20 different ways. so now to be relable i need 550cc injectors, a fuel pump, and a rom tune. thats a lot more money for 250whp and a lot more work than i had thought. i for one do not even have a clue how to replace a fuel pump, but from what i hear, its a pain in the ass. then when it comes to the rom tune i am completely confused. i mean im reading all this stuff about alternate timing maps and cold weather timing change lockouts. it seems like this rom tune is gonna hurt my car rather than help me get the performance i need. i would think that locking out the computers timing maps for low octane or cold weather would be a problem, becuase what if the car starts pinging, wont the computer not be able to change the timing? and 91 is the highest octane i can get here in cali, and i have no clue what so ever how to make race gas. seems like the fuel cut can only be set at 27psi or 17 psi, i was thinking i would like it around 20, because i may want to set my boost to 17 or 18 once, but i sure dont want the fuel cut set to 27. also it almost scares me to be messing around with my engine management what if something goes wrong and my engine fries? also i have no clue about injectors. do these 550cc's bolt right onto the fuel rail or do i need to to more modification for that. and do they just plug right in. at the moment i am totally confused and i do not want to spend an upwards of 1000 for mods that i dont even need to have for my desired whp. please help!!
