Its on my X-trail, getting tuned as i speak.

running 7psi hoping for about 260awhp.

QR25DE+T (2.5L 4cyl)

And yeh that's the manifold im using. I took those photos myself, when i was helping my mate make that manifold.

Just trying to find some more specs on it, cos all i was told is its off a Z31 300zx single turbo...

Its bin rebuilt since then, and i didnt get around to asking the guys at turbo tech if they knew.

I have a hi flowed one of those on my 33, if its the normal vg30det turbo then it will have a .6 rear housing, they had ceramic rear wheels standard but that should have been changed when it was rebuilt, if not they can handle 15psi becuase they have a thicker shaft than r33 turbo's, no idea on front wheel and housing sizes as mine uses a standard 33 comp cover that has been machined out to fit the to4 comp wheel.

what are your thoughts about one of your new wastegate actuators (the upgraded beefy ones you'll run on the .82 rears) on OP6 G3 i have?

Its a CAT machinery actuator. by spec its rated to a bout 26psi. I bench tested it, it started to open at 18psi. I got skyline with 5 broken pistons at moment. So waiting for engine overhaul at this stage.

I'm currently under going some creative modifications to stock R33 2IU turbine housing aim is to push out 270rwkws out of this and possible 290rwkws out of the OP6 rear housings. Well only if current meth works.

Thanks for the support guys, I will let you know if I need your car to do trail runs.

268rwkws @16psi out of a Powered up R33 turbo high flow.

Any one's running 300zx here?

320rwkws out of twin ATR25s on a stock VG30dett Z32 with 750cc injectors, SMIC, and flash tune.

how did you go with the "creative mod"?

The creative mod has been sold to kwrickr33 for evaluation so PM him for results.

Water fittings is M18x1.5 same as your stock fittings. PM me if you need the high pressure CAT actuator when ready for tune.

Its $180. Tested it today. It did hold it pretty fine and blewn up my engine again at 21psi. lol Not sure what the $&%^ happened. Engine's comming out again.

Well. It isn't that bad. because the actuator did hold 21psi. So this actuator can hold boost.

It seems to be the EBC's solenoid failed for some reasons. It was holding 9psi, 12 psi, then the last run was on 15psi. It was all smooth then felt just like the boost line to actuator popped off. Boost went sky rocket. and Boom. Actuator is fine.

Just quick note:

Our last day this year is Tuesday 22nd of Dec and will come back on 15th of Jan 2010. I will get all of yours orders made and sent before we finishing off.

It has been an amazing year, I like to thank you all for your support in 2009.

Merry Xmas + Happy new year to you all.

Bugger..... was it forged or stock? 21psi is getting a bit excessive on an old engine too.. you can see why i dont like anything over 19psi unless i know the car intimately.

The engine originally had 5 cracked pistons through the ring lane area. So I replaced those pistons with a set of brand new OEM pistons and rings. I got them for $500 off some one who bought them and ended up forgies. The engine noise you heard earlier was gone straight after rebuild.

My boost gauge has scale for of 20psi so I guess the tuner wasn't be able to read it if its above. So he said 21psi as the niddel stops there. It was running a ATR43G4 which is identical to a GT3582R in .82 rear.

Well its worth spending $3500 to find out the actuator that works. All for science and my customers.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
