Walbro external 255 lph works, Aeromotive 1000 for overkill.

Depending on your power goals the Supra pump will work, the skyline pump will work, the TII pump will work, and the FD pump works.

Aeromotive Tsunami .... can never have enough fuel pressure on a boosted rotary.

Bosch in-tank pump, and stock regulator. If you are in the build phase, you may want to consider going the in-tank route. Details are here:

Unless one is starting with an SE base to build from, too large of a pump will require replacing all of the fuel lines with larger ones. Which isn't a bad idea anyway during the build.

When I installed a Mallory Comp 140 pump, I had to upgrade to 3/8" supply and return lines due to pump flow volume.

The SEs have the largest supply line of ANY 7 built and the SE pump outputs more fuel than a stock TII pump. When going FI or using an FI rated pump, one must change all rubber fuel lines over to FI rated hose AND clamps.

alright i know about replacing the lines. so the SE puts out more than the TII pump? so could i use this pump if im not goin for more than 8lbs? and what would be the max boost lvl for the se pump. I do have an SE by the way.

o yeah and $50 Walbro 255 fuel pump?? thats w/o shipping.

With the SE pump and stock fuel system you should be good, but I'm not sure if I would trust an older pump. Are you turboing your SE or a TII swap?

I'm turbo. If you're sheap the MSD pump is good to 400whp and a walbro is good to 500whp.

turboing SE....

steve84GS TII

SupraTT pump in the tank
Stock TII sized fuel lines (5/16)
Stock TII filter
Stock TII rails with stock regulator and PD
Stock pump relay/resistor pack retained
550's and 800's

Keeps up with 14psi of boost on my S5 setup, with no issues in the last 5 years.

2 stock 680cc SE injectors
2 1600cc secondary injectors
255lph walbro
aeromotive FPR

works pretty good for me.

josh...just josh

how do you run the secondaries? do you have a turbo center iron or are you running them into the intake manifold? or do you have just a tII swap and I missed it?

rolfs_7

im using the TII UIM and LIM and the TII TB and will be using an after market ECU. the 2 other injectors are in the LIM.

josh...just josh

is that how they are on a stock TII? or is that something that you did, with the injectors in the LIM

rolfs_7

thats how they are in all rx7 that are FI after 85 i believe. TII or not they had 4 injectors after 85. 2 in the block and 2 in the LIM.

Tsi_Xtreme

ditto... except I'm using a N/A S5 intake

I have the overkill one... A1000....

Bosch 044 pumps are nice, but you would do just fine with a walbro, they are easy to find and are affordable, they are 100 bucks shipped on ebay all day
