automatic turbo upgrade (fuel delivery questions)

[interrupt13]

ok guys i have an automatic 1991 GSX.. i didn't realize that it comes with smaller injectors until AFTER i bought my BIG 16g

i am wondering what do i need to do to keep the fuel delivery up ... i wont be turning up the boost just yet.. i just need to run the motor stock and stuff.. the automatics have 350 cc injectors... manual transmission cars have 450cc... do i need to get a set of 450's because my big 16G is like for a manual transmission car (i think?because, i mean.. the automatics have smaller turbos too and all my lines were smaller.. coolant feed line.. oil feed line.. everything had to be made bigger to accomadate the big 16g because my car was an automatic) so i am guessing 350 cc injectors that were used to match the smaller AUTOMATIC turbo is not gonna cut it with my big 16 G... so do i need 450's or what? and what about a higher flow/pressure fuel pump.. fill me in guys please thanks. i'm not gonna be turning up the boost yet... but i might soon... so is 450's enough for now.. or is my 350's enough or what? hope i confused you guys :laugh:

I would definetly not get 450's IMO! Particulary(?) if you are going to be turning up the boost, you should consider at leist 550cc injectors. I got a big16g w/650cc in case I turn it up a bunch or ever upgrade. Those 350's are not enough, nor is the stock fuel pump. You would probably be ok on 450cc and upgraded fuel pump if boost didn't go above like 12psi. What are you doing with a big16g installed without any of these upgrades prior?
