Hey.

So ive got a r33,rb25det..

Just installed bigger turbo,the closest i can compare to would be garret 3071r.

Power fc

external 38mm turbosmart ultragate

Z32 afm and 580cc injectors...

After a huge f**k around with getting it tuned,when i was assured i would have it back same day,it finally got done.

Got 326.6hp at wheels..boost is spiking at 18,and droping back to 15 by redline..

Quote for tune was $500,ended up costing $750.

Now after driving the car around for a few weeks,im noticing it kind of hesitates sometime when light on the throttle,seems to cold start fine,but then other random times it cranking over for 10sec or more and just coughing to life..hot or cold..

Also had to wind the boost down the other day as engine light had been flashing on,and was advised it was detonating..

I know the car's not perfect,but think it mite be worth my while getting the tune looked at by someone else..

Im living near newcastle..so anywhere around here or sydney..

Also any advise is also welcome

cheers

What turbo precisely? It seems like there is more to the story.

I would spend more time talking to your tuner before getting too far ahead. Ask more questions about why the car seems to be pinging, why it is hard to start etc.

If you have done this then what was their response?

yes common sense prevails here please

far too often we see people go get a tune, and any tiny isssue is a mega 6 page thread about the workshop being crap and a rip off before the guy spends 5 minutes talking to the workshop / tuner. please discuss with the workshop and let them address the issues. if you dont want to go back to them, goto another workshop for a 2nd opinion

have a look on your powerfc at the knock/detonation. mine never goes above 20 on 98 oct but when i have only been able to get 95 oct it has gone up to 60-80ish. think the light comes on at 100 or more from memory. make sure you have low numbers

turbo is a billet...i rang mr turbo on the goldcoast to try and track down the exact specs of the turbo,he said it would have similar spec wheels as a garrett 3071r... with .63 rear housing

I cant check knock as i dont have a hand controller for the computer,which was a problem in its self as tuner said his software wouldnt recognize my computer,saying it must be too old,so i borrowed a hand controller so he could tune it,which he did through the controller..

Boost is spiking because of crap bleed valve..two ways of fixing that is:1. another spring in the wastegate to run 18psi,or 2 get an electronic boost controller...?

Im not naming the tuner as i dont know for sure it's a tune problem....

Cheers

my GTR has to be tuned with the hand controller too, trust me my tuner HATES doing it with the hand controller but the datalogit doesnt connect with all POWER FC's. mine is an older model FC i think.

nothing wrong with tuning with the hand controller its just more time consuming and more fiddly going in and out of menu's

hand controller tuning is fine and has been the std for god knows how long?

its only in the last few years workshops have got onto datalogit as mainstream

datalogit makes it quicker and easier (less cost) and lets you be a bit more picky

but there would be hundreds of well setup quick cars with hand controller tunes

go back to the place who tuned it

    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
    • It's TWO steering wheels actually. 😛 one for each hand They are wheels, and they steer!
