There was a recent thread here concerning exactly what it takes to bypass the FD, why you would want to do it, some install tips, and sources for parts to build such a part yourself. Chances are you will see ZERO HP gain from this unless you're car is starving for fuel now. A fuel pressure gauge wold tell you that...
I have been having alot of problem with fuel starvation.....replaced almost everything only to find that my fuel pressure wasnt set correctly.
anyway, I also installed the fuel damper bypass but havint had the chance to test my car yet. car does idle a bit rough and noisy, you can hear the injector pulsating a bit more announced.
while I was installing the bypass line, I realized how complicated and restrictive (seems like) fuel damper unit was. the bypass line decrese the fuel travel distance by half and basically simplified the whole fuel system.
I will let you guys know if I gain any fuel from this mode, although I do not expect any power gain from it at all, just did it for safety reason.
your car idled louder after installing the bypass/ new fuel line? or it was loud and thats why you had to change eveything to find out your pressure wasnt right. Thanks. im about to the mod on the n/a forum theres all the info on what you need to do it for like 50ish
We just had a thread about this. The adapter to the stock fuel rail and to a stock fuel filter is M12 x 1.25mm. If you don't use a stock fuel rail or filter then it's up to your set-up. I ordered 2 fittings from Summit Racing, M12 x1.25mm - 6AN adapter.
I already had a hose with 2 -6AN adapters, one has a 90 degree fitting and the one going to the fuel filter is a 45 degree. I think a straight fitting will work just fine for the fuel filter side. My hose was only about 28 inches long. Just buy a 3 foot hose and cut to size.
After I have installed all the new seals, BCsprings, retainers, locks and buckets,
with T-belt off, put crank at -10 btdc so all pistons are slightly down, install new BC 272 cams, install cam gears, torque cams as per manual. Then turn CAMS clockwise to tdc notches, and than turn CRANK to tdc...
Recently acquired a rhd supra and slowly starting the process of swapping things over. Got myself some glass headlights and wanted to swap bulbs while I’m at it. Been told jdm lights differ from usdm. Hard finding more info on this. Thoughts? Trying to find a quality hid system, seems LED isn’t...
Just installed a pair of S2 taillights on my 93 Supra RZ. I would like to convert to LED. I would like to purchase from here as the prices seem very good.
According to my search in the Forums, looks like I need 2 x 7440 and 2 x 7443 bulbs Just not...
I had a boost leak on my 94 BPU for years and didnt notice it because I still got good boost. So I finally fixed it but forgot to turn my boost controller down. I hit 25 psi 2 or 3 pulls without realizing it. Since then it wont go much over 14 psi anymore.
I did a boost leak test for...
