Big carl has the 6 blade GT30 not the 7 blade that you are running Mafia (from your other post about your probs).

Carl: are you still running the rb25 hot side? I have the same turbo (HP in a box) and got 248wrkw. I am about to put the vg30 hot side on so I dont have to run 19psi...

its definately 500hp turbo checked the id tag with whats on gcgs web site. i emailed gcg yesterday about changeing over the a/r .63 internal wastegate for an a/r .82 internal wastegated one and mark larden from gcg confirmed that they can do it for $450 exhange or $600 outright. also that i should pull 290 to 300rwkws but with an extra 500 to 700rpm in lag or spool up! stuff that i say! well at least i know now. think i will leave it as it is. thanks for your input guys.

So are you running the rb25 Exhaust housing mate? That's what I though they came with from HPInABox?

Anyway it seems to me like the 7 blade turbo with the .7 comp housing is no good with the VG30 zaust housing. I am going to go with the vg30 housing with my 6 blader GT30 and see what happens. Unique Auto Sports have been selling these for a couple of years and seem to be getting 250 - 260 rwkw at around 16 psi which I am aiming for considdering I am currently getting 248 rwkw with 19 psi using the rb25 zaust housing :)

the 7-blade wheel has never been a good match in them :D

its anciet.

Although some people around will tell you GT30's done come with a 7-blade wheel... but this is just another post to prove people are slightly mis-informed

rb25 exhaust housing = 281rwkws.

Not for me big fella. 6 blade GT30 like yours and rb25 exhaust housing = 248rwkw. However I have an OEM manifold and no cams etc... + only 19psi ;)

Edit: I am putting on a z32 zaust housing (well its actually a r34DET one which is the same). I am hoping to get 250-260 rwkw with 16-17psi...

yes ive got the six blader. i had 260rwkws original tune with this turbo but i wasnt running cams , just aftermarket manifold. awesome turbo, power comes on very hard at 3800rpm!. i drive on low boost most of the time but even with 14psi ive got almost 250rwkws. i get 10psi by 3000rpm on low and even earlier on high boost! cant wait to hit the strip with my nittos...

Big carl: are you still looking for a new manifold? Are you interested in selling your current one?

I think my smaller power level is due to me having to use 2 spacers on the Exhaust housing to fit the comp cover next to the manifold. These spacers are not exactly the same size and the one closest to the turbo has a smaller inside diameter and acts like a exhaust baffle...

When I get the r34 housing I will get 1 bigger spacer made up that is the right size.

Garrett should be selling their new T3 flanged integral wastegate GT30 turbine housings in 2 - 3 months , worth waiting for I reckon . Don't know exact time frame - maybe sooner if imported direct . HKS sell theirs as well for the GT3037 Pro S .

Cheers A .

SSSssshhhhhhhh, quiet about the whole vg30 zuast housing being the same as the r34 housings :)

UAS and other importers do not know that they are the same, if they find out the price of the r34 housing will go through the roof.

I talked to them about getting the z32 housing before I knew the r34 was the same and they said that they could not get it anymore, too hard to find...

      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!

      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.
