I might just look to relocate the battery to the boot then mount my surge tank setup where the battery use to be. Should be plenty of room there to install it. Whats the go with moving battery to boot, do you need to run 2 cables from the boot to the engine bay for both +/-, or can you simply earth the factory -ve battery connection onto the chasis and then connect a new -ve connection onto the chasis in boot? Cheers

just a pic of the surge tank setup would be a great start!

Second that!

is there any issues with having a storage of fuel within the engine bay so close to a heat source, i.e. engine?

Lol, saves having to fabricate a new firewall

I thought the blue flexi hose was not to meant to leak vapor?

If i had a setup within the spare wheel well, and then had a piece of sheet metal covering the entire area, would this be acceptable? Cheers

does it need to be any specific capacity, i.e. 2L, 2.5L, etc? Was size line do most people use, -6, -8? Is there any laws or motorsport regulations regarding mounting location, installation of a firewall, etc? Cheers

Oh ok, does it pay to have a tank that has two ports on the top, i.e. one port for return line from engine, and the second for return to the main tank? I've seen a lot of designs where they have one port directly on top, two ports on the side just down from the top, and then one or two ports near the bottom to feed fuel pump(s), have been told the very top was the return from the engine, the two on the side near the top were in/out from main tank, and bottom as mentioned. You saying the port on top should go directly back to the main tank, the two on the side near the top are for main tank in, and return from engine, bottom as mentioned? Does surge tank design make any difference, i.e. cylinder vs cube, etc? Thanks

Sweet cheers for that!

I believe Koom was making up some internal fuel filter sock shrouds to help with fuel surge? Is this still the case? If so, how much? Would this be a better option than spending a ton of money on an external surge tank setup? Cheers

Hey guys, I've had a look through previous threads regarding surge tank setups, however there really hasn't been write ups regarding what goes where. At the moment I believe the following is how things should be setup; 1. Surge tank, bottom outlet(s), plumbed into the external fuel pump(s). Does it make any difference whether the inline fuel filter is pre or post external fuel pump? From there, can either use existing fuel line to engine bay or route teflon braided hose or flexi hose, as these types of hose do not leak vapour? 2. Return line from pressure regulator can be plumbed into the top of the surge tank? 3. two ports near the top of the surge tank; one for fuel in from main tank, and one for return to main tank? Does this sound about right, or is there another setup method I should be looking at? Has anyone used any other pumps besides the Bosch 044? I hear they are rather noisey. Fuel filters, any particular type, micron rating, etc that should be used? Cheers.

what about a .82 on the gtx3076, how would that go? If this would work well and have marginally better spool over my existing 3082 i'd be happy with that.

I'm happy to travel for tuning, I'd rather have someone who know's subaru's well and can tune them to their full potential.

What trade offs are we looking at? I'm assuming going GTX3071 with a .63 will have very good response over my current GT3082 with similar power? Going GTX3076 with a .82 will have slightly better spool/response than the 3082 but more potential for bigger top end? Am I on the right track?

not sure yet, i've heard some good things about the place in tauranga or possibly STM in welly's?

I've got the spec 'B' kelford cam's, 268/264 combo. A GTX3076 with a .82 housing, how would this compare to my current GT3082 with a .63 housing in relation to spool/response and top end power? So what I'm getting from this, either a GTX3071 with a .63 housing or a GTX3076 with a .82 housing?

when you say the 3082 with a .63 is going to limit things, are you meaning it needs a bigger exhaust housing to really get decent power out of it?

those power figures you've mentioned, is that on pump gas? Definitely more than my 3082 is putting out an its a bigger frame in comparison to the 71 and 76. the 3082 isnt too bad, yes its a little laggy and older technology compared to the newer gtx series, but it does the job. the only reason i'd look to replace the 82 with the 71 or 76 would be because of response. However, the price of replacing a comp wheel compared to a new core and cover is somewhat quite different. My intent, when completed is to use it as a daily driver aswell as some track events here an there, e.g road and track series, nz superlap, motorsport club meets, etc. I'm not after huge power figures, more so reliability. If I can 400hp streeter thats reliable then I'd be a happy man.

yeah was looking at that as an option, or the 3071. Some prefer the 3071 over the 3076 for some reason. with a .82 housing what would it be maxing out at?

yep

Apologies didnt sound right, yes different tuners.

Apart from Steve Murch, does anyone know any good turbo repairers in the manawatu / palmerston north area?

good point, no different.

I still think cam's aren't completely right. They were dialed in to what kelford had recommended however others have said it might need changing.
