ive been looking at turbos alot lately and just had a few questions.. speed daddy has a complete gt45 kit but obviously requires more fuel to the motor.. im just wondering if a can just get bigger injecters or do i have to replace the fuel pump.. or both? also, any concerns or other parts i may want to change/install along with the turbo? thanks, Brandon

 

A turbo setup requires more than just new injectors. You need new injectors, intake manifold, turbo headers, induction system, tuning, new fuel pump, tuning, etc. Theres a lot involved with going with a turbo. youd probably be better of just staying N/A with TBI. You can still make a lot of power w/o the turbo. With a turbo, an L03 would still probably be slower than a built 350.

 

i already have all that.. and i kno i needed more fuel.. just wondered if i could get the right amount without changing the fuel pump..

 

so would i be ok with getting an 80gph fuel pumpwith 24lbs/hr injectors? and where would be a good place to buy one? im leaning towards an external..

 

The stock TBI injectors are 55pph injectors IIRC. You'd need a 255lph in tank pump, alot of work on the TBI, and the EBL from Dynamic EFL to get that turbo setup properly.

 

80gph is 302lph.. so i shuld be good there..

and i can keep my ecm with the ebl if i read correctly?

and one more.. wat all do u mean by work on the tbi? new throttle body?

 

EBL needs to be installed in the ecm, a vacuum referenced fuel pressure regulator is a must, you also need a 2 or 3 bar map sensor not sure anymore wich one of the 2.
There is probably all the information you need here http://dynamicefi.com/

Since you are goin forced induction, the stock TB should be ok.

 

everybody on here says to get the dynamic ebl so i will for sure be getting that..

wuld it be easier/better to do a carb swap?

 

doesnt it have a maf not a map sensor?

 

RBobs EBL still uses MAP.

 

I doubt carb will be better, basicaly EBL, 2 or 3 bar MAP sensor, VAFPR, dctrumpet's 30psi FPR spring and a highflow fuel pump, should be all turbo-TBI specific parts you need for now.

EBL has every features needed to tune and control forced induction.

Boost release valve, TBI/carb bonnet+ducting+filter, turbo headers/manifold, coustom y pipe/exhaust, WB 02 sensor, ... are not TBI related.

 

If your new to tuning your own engine? Yes....

 

the local mechanic sed tht the tpi fuel pump wuld work?
