Bad tuner. Needs more timing when cold and more fuel. Also you'll need more duty on the idle control valve. You will need more cranking fuel and a bit of post start fuel. What ECU? Send me your map.

detonation issues standard RB25DET
Dose Pipe Sutututu replied to mikel's topic in Engines & Forced Induction
swap entire plenum from R33 onto the NEO.. then swap pins on the CAS In terms of coils, you could use the R33 harness on the NEO head but the wiring will be messy using the NEO coils.. however if you use the NEO coil packs and NEO coil pack harness it plugs straight intot eh R33 loom NEO coils and NEO harness are essentially and schematically the same shit.. just the mounting tabs are different and the NEO are all aligned in 1x direction where as the R33 RB25 is all over the shop like a hooker on meth, thus the coil pack harness/loom (whatever you call it) have different length leads. -
R33 gtst missfiring problem?
Dose Pipe Sutututu replied to Mitch r33's topic in R Series (R30, R31, R32, R33, R34)
How about hose from fmic to your turbo with no controller? Start there then work from there. -
R33 gtst missfiring problem?
Dose Pipe Sutututu replied to Mitch r33's topic in R Series (R30, R31, R32, R33, R34)
Problem(s) could be from either the Superspark coils (which are rubbish, sorry to be blunt) or faulty OEM ones. Best to get Splitfire ones or go Yaris conversion or LS conversion coils. -
See if your voltage drops as RPM increases, just log it in the halal-tech. Add more dwell man, less will misfire, I have 3.5ms in the midrange for mine. I'll screen grab my table for reference when I'm home.

Run more dwell till they melt LOL. Mine is at 3.5ms in the midrange tapering down to about 2.2ms up top No misfires these days

Nistune is the best, especially with the feature pack and a R35 AFM

detonation issues standard RB25DET
Dose Pipe Sutututu replied to mikel's topic in Engines & Forced Induction
I can only assume you upped the compression with the NEO head and kept the same tune for the original head/motor combo. NEO heads have much smaller combustion chamber volume and when used with stock R33 pistons you've efficiently upped the compression. Throw in a stock motor, cheapest option for you since you're after such little power. -
OEM coil pack harness no longer for sale. Turns out the R34 NEO and R33 will work however the plug lengths are incorrect as the coil orientation is different. Schematically the harnesses are identical. Now for sale is my Wiring Specialties R33 RB25DET S2 coil pack harness. This is about 1.5 - 2 years old or so. $100

New clutch for my R33 Gtst
Dose Pipe Sutututu replied to HCD_Velcra's topic in Suspension, braking, tyres and drivetrain
For anyone reading and thinking of getting a competition clutch, go Google Competition Clutch Explode, Competition Clutch Problems, issues etc. If you're on a budget and poor like most of us, get a NPC 10" Carbotic clutch. Pedal effort is softer than a stock clutch and there's about 1.7 to 1.8 tonnes of clamping force. Yes they may be Exedy parts in those clutches but they're completely different to your standard Exedy Sports range clutches. If you have coin go Nismo Twin -
Braking upgrade
Dose Pipe Sutututu replied to Adz2332's topic in Suspension, braking, tyres and drivetrain
US edition of anything isn't a good thing lol. Just remember you'll need the bolts from a R34 GT-t when you install them. The caliper bolts from a 350Z is too long. I think for you Trump lovers FRsport or Z1Motorsport have the correct bolts for sale. -
You would think so but Australia being Australia it's state based. Same reason why each state's registration and licensing system/process is different. TBH it's bs, but it is what it is and I can't change anything lol.

Light throttle jerking issues
Dose Pipe Sutututu replied to AngryRB's topic in R Series (R30, R31, R32, R33, R34)
It's called "ACCELER." and the screen looks like this.. unfortunately it's upside down (got it off Google). You will need a wideband and see what the AFR is like when you jab the throttle vs. RPM. Of course too rich will stumble, too lean will stumble. Column 1 = RPM Column 2 = how much fuel in ms Column 3 = how long in ms Because you're running larger injectors than stock, I would say reduce the amount in column 2 by the percentage of your injector size increase. So OEM is 370cc right? now you have 1000cc or so.. that means you would only need 37% of the original throttle pump values. Play around with it, however you will need a wideband. -

Garret gt35 fully stock RB25 neo??
Dose Pipe Sutututu replied to 26DETT's topic in Engines & Forced Induction
Yep, you'll reduce exhaust back pressure, make more power, less things glowing on the hot side. I did that only mod and with the same timing map, same boost, same turbo (except it was a BB centre this time round, same comp/turbine wheel) and made extra 20kW off the bat.
