can anyone tell me if 550 injectors will fit straight into my vr4. will i need to get a bigger fuel pump (mine's standard)
 
Fuel pumps mandatory when going bigger injectors.

The walbro in tank replacement fits well with the appropriate fitting kit. not a hard job at all.
'runuts' had them for sale on here or at least he can tell you the right fitting kit, i bought mine off him.

Also watch out as there heaps of fakes on ebay ect so buy form a reputable source.

Read up on here under the fuel section on how to do it. heed their warning on the fuel line nut being tight.

What are you doing to tune for the bigger injectors? or you'll be extremely rich if you just throw them in.
 
trying to keep up with the evo's on the track. they are just too bloody quick. am also looking at a larger turbo
 
Depending on the injector, you may have to bypass your resistor pack.

RX7 injectors are a straight fit also.
 
i'm running late model evo 560cc injectors (evo 8 i think) on my vr4 motor.. straight fit..
but yes i'm running a bigger fuel pump and microtech..
these injectors go for cheap on evooz..
