R33 Gtst S1

Results as per my signature... currently 226.5RWKW (will scan dyno sheets in tonight)

More goodies being installed currently with ECU to be installed next week:

555 Injectors

External fuel pump

FPR

ECU (Adaptronic)

Custom Plenum

Metal Headgasket

Cam Gear

Cam Shafts

New hoses throughout engine just incase lol...

GT3540 for when Stage 3 highflow is max'd out

And then..... wait for stock internals to crap themselves before installing a RB30 bottem end :) (Dad won't help me build the bottom end whilst there is a perfectly good one still working in the car :dry: )

Now sitting at 262.3 rwkw on 16psi.. We made 279rwkw on 18 psi but it the highflow was being maxed... dropped it back to 16psi to be a bit nicer the the turbo :banana:

Added the Adaptronic, injectors, fpr, plenum (although awaiting another :) ), cam gear + fuel pump!

Tuned to run really rich due to the plenum leaning out no3 with the airflow. New greddy plenum and Garrett to be installed in two weeks.. will update then when the afrs are a little more friendly to my fuel economy!

1995 R33 GTS-T

std internals

n1 water pump

HKS stage 1 inlet cam

HKS stage 2 exh cam

HKS adj cam gears

HKS timing belt

HKS air filter kit

nismo FPR

Plazmaman plenum

sard 550cc injectors

walbro fuel pump

custom GT3076 ext gate turbo with 0.63ar exh hsg (i would recommend 0.86 for RB25)

TiAL 38mm W/G

s/steel hi mt exh manifold (brand unknown)

GTR front mount custom piping

apexi AVCR (would use HKS controller if i was to choose again)

apexi PFC

It made 259.8rwkw at 7000rpm but has very stong midrange but lower tourque and power tapered off in the top. I will try and get a 0.86 hsg and re-dyno and see what the difference is. But as the package stands it is fun to drive and the boost is only set at 1 bar, so with bigger hsg and 1.1 maybe 1.2 bar it should make 270 kw with more tourque.

      r34's love to squeal

      By Nizzy_R34 · Posted

      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.

      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.
