EFI surge tank under car
EFI surge tank under car
I'm at the stage where I need to start looking at routing my fuel and brake lines and planning my fuel system.
I'm running a L20B with ITB's. I'd like to mount the surge tank and the lift and EFI pumps all underneath the car.
It seems that space in the rear is quite limited, does anyone have any pictures of a completely underneath the car setup like what I'm describing? I still have the spare wheel well in place also.

Re: EFI surge tank under car
Any reason to not run an in-tank pump?
Alternatively, there is room to mount a tank and pump on the front side of the rear crossmember and under the rear seat bottom bump.

Re: EFI surge tank under car
I have an intake pump out of an S13 and I even welded in the cup thing, it sucks big time at the track, if I get below 5/8's of a tank it fuel starves. So lame!

Re: EFI surge tank under car
Yeah icehouse a friend has a 610 with an in-tank pump and he has the same problem.
I did look at that region you mentioned okayfine, I just can't visualize in my head how I would lay out 2 pumps and a tank + filter in that space.
Alternatively those new Aeromotive Phantom kits look quite nice but spendy and I would be super disappointed if I shelled out for one and it still starved around corners.

Re: EFI surge tank under car
I'm running a Walbro 190lpm external pump in the trunk with a large diameter (I think for a 300zx) fuel filter and have zero issues with starvation. I'm not running a Turbo SR, just a NA S14 with a few mods but zero zero starving issues below 1/4 tank.

Re: EFI surge tank under car
As Julian noted above, there is definitely space under the car in front of the crossmember. Check out the photos in my Bronze build thread;
http://www.the510realm.com/viewtopic.ph ... &start=165
When I assembled the the car, it was carburated and the fuel pressure regulator shown was in use. With the EFI conversion, that was regulator was scrapped giving more space. I'm also using a Nissan 200SX rubber isolated pump mount and Nissan pump at this point, both of which are much more bulky than the pump you mentioned. The next mod is to put a 1.5L (1.5 quart) capacity "surge" tank on the driveshaft side of this photo in the same area. It would be custom, but there is certainly room.
Right now, at 1/4 tank of Fuel and without a surge tank, it starves on RH corners and it is a PITA! I even upgraded the feed line in the tank down to the pump to 1/2", and it still starves. So the surge tank is necessary. One test I do need to complete is to confirm that the capacity of the surge tank will feed the pump for 7-10 second range, as I think this would get me through any cloverleaf hard on the throttle, which I think is the worse case situation.

Re: EFI surge tank under car
We hung a surge tank under James' green car. There is a Carter hi volume lo pressure pump feeding the surge tank, and then the typical and ubiquitous Walbro GSL392 feeding the high pressure side out of the surge tank into a filter of some sort.

Maybe James can post a picture of it where it was mounted, under the car, between the little frame rail bit and the wheel well.
The volume of that tank has proven to be adequate.

Re: EFI surge tank under car
Here's an inline pump and filter mounted to the vertical surface of rear passenger seat floor. Plenty of room for all that and a surge tank. It was only after getting all this done that icehouse suggested mounting the pump to the crossmember, since the crossmember had rubber bushings to the body already.

Re: EFI surge tank under car
Hmmm... only pic I could find. Gotta crawl underneath and get a few shots.
Here is the topside. Low pressure Carter pump feeding the mini surge tank - you can see Rob's handiwork poking through the trunk floor. This system is basically bullet proof with the only issue being one of the wires to the Carter pump vibrated off during a club run. Never have I had any lean conditions in corners with low fuel either.
The AN line that runs up is the return line and is plumbed into the filler neck with a steel fitting welded on a 45 degree angle aiming toward the tank. With the car running, you can pop off the fuel cap, look down the filler neck and see the fuel shooting back into the tank.

That is one of those simple, yet ingenious ideas that make things easier.

Yep I think I'm going to do this too - I figure if I can hear the sound of fuel dribbling into the tank then it should be extra reassurance that I have enough fuel supply.McShagger510 wrote:

The IDx 10 concept is based on the 510 in the same way that the urinating I was doing last night was based on a 30 yr old single-malt scotch.

Re: EFI surge tank under car
I ended up making a tank, as there was nothing on the market that would fit in the space I had available. Dimensions are 100 high, 190 wide and 65 deep (in mm, because I'm not a savage).
I think I'll probably weld a Bosch pump bracket to the surge tank, and have a Carter lift pump somewhere nearby underneath the car too.
Here's a pic, in case anyone is thinking about doing something similar.
