uh skyline engine. hmm dont think that will fit but you never know people do crazy things.
from what i have seen from previous people wanting to do a turbo charged setup with an NA it sounds like to much work and more money than nessisarry so ill tell you what everyone else will tell you , GET THE 7MGTE or if you have the money 1jz or if you really dont mind spending about 3k 2jz.
but swaping out a 7MGT with the 7MGTE will save you a bunch off the line, plus you will then get the turbo. and spend about 1k to get a motor with probably less mileage than what you have right now on your non tubo engine.
if you want you can twin turbo the GTE motor but requires a little more work. and as you brang it up about bigger injectors then you probably heard of fuel cut. you need to go either MAP sensor, Standalone, Engine management, or a lexus MAF. then get the bigger injectors. then fuel pump to accomidate all that air being forced into the engine. and to keep a good steady A/f ratio.
red led lights for the dash. well thats simple goto like a auto place and buy some new push bulbs
they are like 1$ a piece and just get the red ones. or from what i have heard just take off the little green covers and use a red marker on the bulbs or even touch up paint.
and also how much money are your planning on spending?
