If you share that 3.5" exhaust between the 2 GTX63s it is only 1.75" diameter exhaust for each 440hp turbo!

That's a huge ask from 1.75"

That Z32 shows its doable just open up the inlet and exhaust more and if it doesn't work then I'll right them off.

But for now there my 600 wheel horsepower turbo of choice

Front housing machining has been done on my GTX2860's, picked them up from MTQ this morning.

I'm about to do a multi week roadtrip down to Victoria, so they won't be going in for a little while. I'm hoping maybe January. I need to sort out a few things first, like fuel system and exhaust.No point putting them in if something else is holding them back.

Gorgeous wheels pete, how much power are you aiming for?

E85?

Just spin them as hard as you can too..

I've been held up by my machinist he hasn't given me my head back yet so I'm able to delay my turbo choice.

As above, they're -5 housings so .64 ar I believe.

And yes, e85 of course!

Power wise, that's to be determined by my work outlook. Worst case I suppose would be standard engine with arp headstuds. Id still throw a heap of boost in but may be limited

Nothing wrong with the standard bottom end, as you said just wack a set of ARP2000 studs and also maybe some drop in cams and away you go!

One for you pete, GTX2860's custom high mounts on a std 2.6L pulled 373 rwkw on only 17psi using stock ported comp covers and says .73 turbine housings??

Definitely different

Does any body know if a -9 rear housing will work with the gtx cartridge? Wheels are the same diameter just a different trim, 76 vs 62. As i have -9's now was wondering if i just got the machining done and swaped out the cartridges.

edit: Looks like the -9 rear exducer is 34mm while the -5 is 41mm so I'm guessing no, only other question is will a gtx2860 front compressor fit on a 2859r cartridge?

    • 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.
