On a 2.6 you definitely need the right setup/method to be responsive :)

Daz has the right ingredients and method heheh!

By the way Daz I wasn't trying to be a smart arse :) I had good results from GTX2860's with a stroker setup, stock cams and BP98, but went shit when I put in cams and got another tuner to tune the setup when I headed north...

love to see the dyno plot as there's nobody who has shown one yet for these turbos.

Why so many questions on my set up RP are the sickest bro :)

I understand you made shit numbers and I'm guessing that's why you won't disclose your numbers?

We're all here to elevate performance of our cars in a collaborative n helpful way.

At least I thought that's what it was all about.

2 z32's been on the dyno in the last week. 1 with gtx2863's made 565.7rwkw @ 30psi (450+kw by 4500rpm). It actually mades 565kw at 5800rpm.

The other has gtx2867's. It made 770rwhp @ 32psi. Laggier tho as it had no vtc.

that's mega, I noticed Z32s respond well to the gtx 63s. thanks for sharing too

The VG30+GTX2863 combo is purely mental. I imagine however that most people would have a mental breakdown or two getting everything right with the build to get those great numbers though. Was the GTX2863 car yours mike?

Why not share your results?

he made over 400wkw on a built 2.6L on 2863's, prolly won't share because he blew his engine up.

I just wanted to know how it ramped up compared to Simon's 2.8L with same 2863's.

I'll soon find out tho :)

Nah not mine Pete, one in Syd and one in Perth. The one in Syd has had a few hicups such as 2 snapped cams.

I am still on 98 but that will change soon. inb4e85cheat

I'm sure it varies, the tighter the tolerance the better it will work, but too tight and it may rub once the bearing tolerance gets loose.

I would say .4mm would be ballpark. Hopefully someone with BB turbo machining experience pops up as I suspect you can go with less clearance with a BB core.

    • Also, the cause of fuel spills and smells from the top of the tank is almost always the rubber hoses that are up there, not the tank seal.
    • 1. No, as you say you can remove the connectors and fuel lines. Before you do make sure you remove fuel pump fuse and crank the starter a few times to release pressure, and also loosen the fuel cap (just in case the tank is slightly pressurised) as it will pump out the lines otherwise 2. Not necessary but you are right, if it is the factory pump it is at risk of failing after 25 years....Changing it is not hard but potentially not trivial as you have to make sure you have the right pickup/sock for the pump to suit the tank, need to make wiring connections (crimped butt connectors would be fine) and have to mount/adapt the new pump in the right place in the cradle. Not impossible but don't start the job if you aren't confident. Also, the plastic nut that holds that seal in place can be really hard to remove. If you don't have a fuel nut removal tool it generally requires a big screwdriver or similar to bash the ring around a few times before you can get it by hand. Also the fuel lines can be very sticky on the tank lid fittings, hose removal pliers can help or if not twist the hose on the fitting (eg with linesperson's pliers) to break the seal before you try and remove it. Finally, mark the feed and return hoses so you don't put them on backwards and seal them with an m8 bolt to stop crap getting into the lines while working. Add a little grease in the threads of the plastic lid when you go to do it back up as a gift to your future self, and make sure you put it on evenly/not cross threaded.  Having said all that, most likely the lid just needs to be either tightened or removed and put back on without being cross threaded...the seal itself is usually pretty good.
    • Another weekend and another project I have questions about.... I bought a fuel tank sender O ring to install on the car because I'm quite sus on what I've got now.  1. No "whooosh" sound when opening fuel cap 2. If I fill up full tank, there will be a small leak under the car and it comes from the top of the fuel tank, dripping along the side. Stops after a short while 3. Hot days = 50/50 chance to get high as a kite inside the cabin if the car was in the sun for too long This is what I bought: https://www.amayama.com/en/part/nissan/1734279900 My plan was to just replace the O ring but I've got some questions: 1. Does the whole fuel pump assembly need to come out for me to replace the O ring?         Or, could I unplug all the connectors and fuel lines at the top, take off the twisty part (17343) and put in the O ring from the top?  2. Is it a very common thing for everyone to just change the pump whenever doing this?        I see the Walbro 255 gets thrown in a lot but I've got no issues with my pump so far. When I did the tune, I asked the guy to check my fuel pressure and he said there were no issues too. But is it just a good idea to change to the 255 anyway as the old unit may have been in there for so long? The 255 seems to be a direct fit for GTT (I got no soldering iron)  
    • Normal speedtek issues, bin it and go cdoo# or 8hp. So many issues with these gearsets, a mate went through 3 rebuilds and multiple parts with heat, bearing and vibration issues.  
    • I wouldn't go near them, they are rubber seals for a reason. Just chuck new cam cover seals, half moons and the spacers for the screws every decade or two. I add a really thin layer of silicone too and it seems to hold together OK
