Re: a pic & some ideas, (LONG)
g`day,
in theory it is as easy as that, theres a few little bits n pieces that you have to do aswell, like tap in a oil feed for the turbo(from the pressure sender), run water hoses if the turbo is watercooled, put an oil return in the sump, setup a cable for the throttle, install a boost guage, but thats all minor stuff that you should have no trouble with if you got time and tools.
the cost to convert to efi is quite high thats why i went with the carby, looking at around $1000au for a cheap programable computer(why use factory if you want power?), around $50each for 2nd hand injectors, then theres about $500 to rig up a decent efi fuel system(efi hoses, return line, low pressure pump, anti surge tank, high pressure pump, regulator etc.), and then theres all the sensors and tuning which all adds upto a lot.
for less than the cost of setting the car up for efi you can have a turbo up and running with a carby, plus if you ever want to go to efi later the amount you spent on the carby setup isnt going to be a big loss, its just a few bits of pipe really hey.
A single 2" SU would probably be good enough for about 160-180hp at the wheels, a 600holley should be good for around 250+hp if you built the motor up to handle/make that much.
you can make some good power with this type of setup still, i know a guy over here thats running a similar setup to mine but he use`s 2 cd175 stromberg carbs and hes making 230hp at the wheels from a L20b(2L 4cyl), he runs about 15-20psi with water injection and his setup was pretty cheap too. he`s planning on going efi later on and hopefully getting around 300hp, not bad for a 25yr old sohc 4banger eh.
im actually quite surprised that theres noone else on here running a carby turbo setup.
later
