thanks fellas, the 22psi run didnt get much more power than the 18psi (another 40hp or so) so it looks like its running out of puff on the old t04z, it is a conservative dyno compared to some other ones in perth so it should crack 600 on other dynos if im lucky. looks like its turbo upgrade time to something huge that will make full use of the stroker kit in the near future and keep the Z for road use :huh:

the sound of it at 8500rpm is pure car porn :angry:

  • 4 weeks later...

I said it before, and I'll say it again...

Holy Snapping Ducksh!t Batman!!!!

Gonna hit the strip anytime soon? Let us all know when so we can come down and watch!

new dyno tune, results are 585rwhp on 19psi and 605rwhp on 22psi (didnt rev to rpm limit due to problems so still abit more in it)

ill post graph tommorow

Brad?

Is this for a Stagea or R33 GTST, because your user details list a R33?

Paul im running the 0.81, maybe there is a difference in hks vs garrett versions for power ;)

the dyno i used is very convservative too

lets just say the car is currently engineless and im planning on building a different setup and this engine go into a rwd track car. Not by choice that the motors out soo quick but some problems happened on the dyno and now the motor is stripped with pistons and rods etc all out.

oh i just love cars :(

Brad, That's a real shame ;) I'd love to do back to back comparison's of HKS versus Garrett, but I'm guessing your on a T3 hourins, not T4 ?

hey thanks guys for the support, that engine will possibly be back in the stagea but not for a while, ill be running another engine combo for the time being.

Paul my turbo is a t4 flange (my manifold is from Trust and suited for a t78/88).

well, $800 later. was going to be a grand but they did me a good deal. can recommend Boostworx for sure.

exhaust manifold was snapped clean in half, replaced with same, busted radiator when I stopped the car in front of the workshop, replaced with slightly thicker GTst unit, new exhaust studs, redid all the intercooler pipes (lol they asked who fitted it hahaha - me ! dodgy home job) for me, all's running well, bar the RESTRICTIVE rear muffler.

Knew I should have changed it back over xmas. Will get an oval 3inch straight thru muffler, have the adjustable exhaust cam wheel fitted, and retune to 16psi.

exhaust manifold was snapped clean in half

You are kidding! Mine did the same, it started to make exhaust leak noises a couple of weeks ago, which gradually got worse. So yesterday I thought I would tighten up the manifold nuts, they are the usual culprit. Been puting it off as the heat shielding is always a bitch to get off. With the heat shielding (finally) off I was amazed to see a cracked exhaust manifold, all the way around the log between #3 primary pipe and the turbine flange. I have never seen that happen before, and now I read the above.

I will post up some pictures tonight.

>_< cheers :)

    • 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?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
