Like many of you I've got all the bells and whistles but I fear now that the Cosmo

intank pump may come up short. New Ito motor soon. I have to install the 1600 secondaries and the cartech boost assisted /fuel regulator.

So what are the short commings of this. I have had Bosch pumps before on my Haltech and I can do with out the BUZZZZZZZ of the pump.

 

The supra TT pump flows better.

 

Is this a straight up change or some mod work needed? I may want to go there like yesterday.

 

The supra pump is the exact dimensions of an FC/FD pump. It will bolt it no problems.

 

what about the Z32 pump?

 

The High flow Walbro flows more than a Supra pump when under 12V. The Supra pump will however flow more than the Walbro if you hot wire it to get 14V BUT I hear that people are starting to say its killing the pump early. Hot wiring the Supra pump used to be the thing to do but now people are saying thier pumps have died in as little at 10K miles after they hotwired it for more voltage.



Makes sence, the pump wasnt designed for that. I'd have more faith in 2 Walbro pumps at 12V.



Depending on how much boost your going to run though you might need something BIG.
