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.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
