Walbro 450

[gerryeddie]

Anyone installed a Walbro 450 in a GSR? How hard is it to fit in the cradle compared to a 400?
Currently have a 400 but it's not E85 approved so looking to upgrade to be on the safe side.
Also, looking to hardwire at the same time as the unwired 400 is running out of pump up top on E85, but has anyone seen issues of too much fuel pressure with the bigger intank pumps once rewired? Fuel return oriface always need to be drilled out or usually no issues?

Depends on your ecu, you may be able to run dual pump speeds, and leave your orifice alone.

Are you referring to a 416?

 

[gerryeddie]

416/450 the same I believe - so yes guess I am referring to a 416 also. Car is running Evo 6 ECU.

 

[evo-gsr]

I have same setup in mine. Rewired. Evo 6 ecu also.
No issues whatsoever.
its a straight fit into evo / gsr cradle no fitment issues here.
if anything I have upped the base fuel pressure to give the injectors a bit more headroom.
Whos tuning the car?

Thanks mate. Burnzy will be touching up the tune.
So do you have an aftermarket FPR fitted though? Was that necessary or just a precaution?

2 mods to the cradle to install fit without any mods the the tank.

 

[gerryeddie]

Thanks for the pics mate. GSR/Early evo? What mods were required to the cradle?

Evooox has it all in this awesome thread. Details and pics as well.

 

[gerryeddie]

My bad...only looked at it quickly before. Thanks all.

 

[khubner1]

in mine only a simple wiring mod and cutting of part of the fuel feed (will be obvious when you try to install)

 

[evo-gsr]

Neither of which would really be classed as modifying the cradle in my eyes.

 

[EVOCPE]

It's not modifying, it's a part of fitting, modifying involved cutting, welding, bleeding, swearing and sometimes even going back out looking for the same part to try it again

I cut stuff and swore so it counts

 

[EVOCPE]

You only cut the inlet pipe, so doesn't count...

 

[evo-gsr]

My thoughts exactly ^

I just reading on dsm tuners that these 450 walbro are running out of puff at 28psi boost level. Something to keep your eyes on.
