Do you still have Hicas?? If not, the two hardlines that run under the car are perfect for weld on fittings and some dash 8 hose, in my application we use 2 044 pumps via a 4l surge tank to a twin entry fuel rail, sard fuel reg and 1 std line for return.

i have the hicas lock kit on my garage floor but what would i need weld on fittings for?? i thought it was just a surgey and two pumps in the boot running lines under the car to the twin entry rail.

Yes that works, mines like that.

If you do a search on this topic youll see threads with all kinds of into and pics etc

best thing to do for that number IMO is to have 2 x 044 s running from a surge tank with stock pump as a feed. Do a new return line to the surge tank, twin entry rail, easy as

Yes...mines also like that....good for 1000hp at the flywheel.

I use the stock feed and return as feeds and a -6 braided line as a return. 3 Bosch motorsport pumps (one gauze bottomed swimmer pump in tank and two 044's off the surge tank), 1000cc Blitz injectors, GReddy twin entry fuel rail and a Sard regulator.

Works well :P

i didn't use the hicas lines for fuel lines instead

2 stainless lines feed and 1 return from gas tank all the way to the front

3 HKS 280L fuel pumps (intank)

2 inside the SARD 1L fuel tank and 1 in OEM fuel tank

aeromotive FRP

Tomei fuel rail

1000CC injectors

that is a flash setup, very nice with the gold fittings, gives it that japanese feel about it - nice gtr btw :P

yeah the sard surge tanks are good. they are basically like a mini fuel tank with inspection port on the top and you can mount your 'external' pumps inside it which does quieten them down a little and keeps them relatively cool too as they are sitting in fuel. it's a good way to go.

On the topic of fuel pumps, whats the max an 044 can handle?

I've set up my 044 intank pickup on my BNR34, looking to push around 380-400awkw on 2530s.

DiRTgarage, from memory you're making around 402awkw on 98 with 2530?

Any suggestions? Wasn't a lot of details on the article from HPi the GT-R special... haha!

a single 044 can handle the above quoted power BUT you need to take into consideration the integrity of that setup i.e. what if u get fuel surge which u are gauranteed with that sort of power & assoc. g-force?

what if that pumps fails for any unknown reason, the only warning you might get is 'pop'

also, running 400awkw the engine becomes much more reliant on fuel delivery

in other words, i think u would be mad to run a single fuel pump as many others would agree - walking on egg shells

With regards to fuel surge, i always keep the tank pretty full. Usually pour when there is about a 1/4 of a tank left. However, i guess i could always keep it above half in worse case scenerio?

If the pump fails, wouldnt the engine just turn off? I recall driving and the hose to my surge tank came lose, i couldnt accelerate no more and the car just gradually turned off? So what kind of pop are you talking about?

I've got 800cc sard injectors, sard fuel rail and sard FPR and its dual entry so i suppose i have done the fuel system oks, however, i used to have a sard surge tank though i had petrol smell in my car, is that common when using surge tanks? I found it quite wierd and couldnt take the air pollution inside the cabin!!!

i thought u would respond with "i'll keep the tank full" as i has similaar thoughts but then bit the bullet & ran a proper system

more than likely engine will just turn off but if you're pushing that much power you dont want to run lean at all - pop as in engine failure

i know what u mean about petrol smell in the car - ive had that before & apparently it boils down to the type of fuel hose as some are porous? correct me if im wrong but this is what i was told

      Anti Squat Kit

      By robbo_rb180 · Posted

      What are you doing with the car? street car or race car? People get hung up on the squat of the s/r chassis rears. There is positives to the squat if a car is setup and driven correctly for it (correct ride height, spring rate, alignment, damper valving). Generally just lengthen the rear traction arm by 5-10mm and that will help the squat and bump steer too. You are also correct with the roll centre too. This too also needs to be adjustable if you start messing with suspension geometry.   Having done quiet a bit of testing on race cars this year in regards to rear squat, I've seen some big positives from it in regards to drive off corners and traction.

      I find I am using the MX5 for everything except long overnight cruises with Jackie, or, if picking up the kids to go somewhere, the SS has so much more room inside, and is much more comfortable if your going to be doing Hwy driving for 6-8 hours And the MX5 isn't bad in stop go traffic for a manual transmission car, whilst the clutch kit has been upgraded from stock, it is still light, and also not having a stupidly light flywheel in it helps as well, I've spent alot of time sitting on the M5, M4 and M7 stuck in traffic when plodding around the Greater Sydney Region in it Another benefit is MX5's are not really a car that gets stolen, you can pretty much park it anywhere, and it will still be there when you return

      I can totally get why you like it for that sort of commute. I was thinking BoganDore because it's such a lazy drive, for things like stop start traffic.   I used to do over an hour in stop start shit from one side of Bris to the next, twice a day. My choice of car was larger displacement, with an auto. Basically for torque in low rpm/very low speed, and no clutch pedal. But loved a fun manual for the weekends, which the partner has (plus had the LandCruiser too for other fun drives). I now have an EV as a work car, and I tell ya what, ultimate daily driver, especially if youre out of energy, like I often am after work. I don't even need to touch the brake pedal   That said, I'm presently rebuilding the Liberty GTB to get it setup for weekend drives and track abuse! So small high revving turbo engine with 6 speed cog swapper!   But for your style of commute, I'd probably take the MX5 too!   For those choices, I'm ignoring fuel economy. Because I know how atrocious V8 daily life is for fuel from when I used to daily a manual SS, ha ha. Hence why I know I love the daily rumble of a V8

      People just don't understand how good MX5's actually are and how fun they are to drive, park, manuever. You feel like you have got some fun cheat code, while everyone else is sitting in their luxobargeSUV like normies who missed the point of living. It really is that noticable. As long as you/your stuff fit, and you're comfortable (they are), a MX5 is the best car on earth to daily around.
