From what I've heard the gslse fuel system was barely capable of producing enough fuel for the car itself. So a dry system may not be the way to go without swapping in a fpr and walbro. I used to run a 50 shot on the 12a and it took it quite nicely. i sprayed into the top of the carb and it actually woke the car up a lot. All I can say is make sure you are able to produce enough fuel!

Kool man cuz thats what i thought it waz happenin with my pump, wen im cruzing its fine but if im cruzing and i punch it oround 6 gran the car cuts out like it looses all power but if i keep my foot on the gas ill hit back up once it has time to buil up pressure but it nice to know they can take gas with the right mods!

FYI. The stock GSL-Se fuel pump has more output than any stock RX-7 FI fuel system including the FD's. I don't know where you get your info but you might want to do more homework.


Chava,
If you are experiencing this problem it may be 6 port actuator related also. There are other factors that may be causing your upper RPM bog..

ok, yea i thought it might have to do with something else like the fuel pressure damper because its craked or something like that, because i got all the intake manifold striped of the 6 port actuators and plugged everything up but what had me worried was the fact that ther is not alot of people with knoledge about rotaries so when i asked people about spray i got mixed answers that it would take it very well and others that i should not do it cause they dont take it very good..
but thanks for the info doc.

I found this in the chronicles of a turbo 2 swap thread. I am guessing this is what I read. Take it for what it's worth.








Oh yea, forgot to mention the fuel pump. Spent alot of time researching the fuel pump issue. Basically here's the scoop--somebody pipe in if you think I am wrong.

I have seem some threads on the 1st gen forum suggest that the GSL-SE fuel pump will be sufficient for use with a TII engine. And to that I have to say--I dont' think so. The pump is lacking in both pressure and flow. A quick look at the specs will show that:

TII pump = 71-92 psi and 132-198 lph
GSL-SE pump = 50-71 psi and 102 lph (min)

I know gslse's had some highpowered injectors, but I always thought the pumps were no good. Anyone else wanna chime in? I'm curious now. I HATE giving out wrong info. I've been looking for some good info, and found a few things against using the gslse pump but nothing concrete.
