Ecotec needs more HP

[Pooh Man]

I f anyone catching this is knowledgeable, please throw it out there. Does anyone know the flow rate of our stock fuel pump?? I ve seen OEM replacements quoted at 40-50GPH ( 1 G is 3.78 L), which would adequately supply my expected HP goal, but will probably go with a 190LPH universal Walboro. As for injectors, I am shopping for 320cc- just about what the VXR runs stock, but does any one know what style I need for direct replacement( EV1/EV6). I have never shopped injectors that weren't an OEM/JDM upgrade so I am stumped...help.

Shaved 3 lbs....not much but something is better than nothing. I fell short of my original goal but I didn't want to keep hacki g this thing to the point of sacrificing the structural strength

As long as I am talking to myself I'll continue. I FAILED on the header install. As I thought , the bolt pattern was a match, but the bottom of the runners hit the hard line that runs across the front of the head, literally, this attempt failed by about a quarter inch- Im pissed off, this would have been a nice turbo piece-there is a good amount of room for the T25 I was planning on running. Oh well, back to brainstorming, a quarter inch set me back months.....F..............

What hard line are you talking about? Pics?

I believe this runs off the cooling system? This is the only thing preventing my plans at the moment . As stated above, the runners out of 1 n 4 hit the silver hard pipe n keep the flange about a quarter inch off from sealing on the cylinder head

It looks like it should be possible to chop a section out of it and run a rubber line. Perhaps with a heat shield of some sort over it to protect from heat.

Or, chop a section out, drop it down with rubber line, but use the cutout section where it gets close to the manifold.

Pooh, just thinking out loud (from years of fabrication in the past) could you not use an AN-10 braided line with a foil/nomex heat sleeve to help insulate? You would need to fabricate an AN10 flange for the pump, (or mod a universal flange) then a fitting to the block (or wherever this line feeds to). Although braided line is not as flexible as a rubber line, it should be more reliable in such a high heat area, and let you bend it out of the way of the manifold. Aside from that, you could fabricate a new line out of stainless, but I have never worked with tubing that small, usually just use high pressure braided line on custom apps.

Clutch .masters FX300 finally arrived

First pic didn't go thru

i'm 90% sure just by looking that that line keeping that manifold from fitting is only a coolant bypass. I would totally reroute that.
