Ok guys I've done a bit of searching around and haven't really been able to find anything that relates directly to these mods on an Rb20DET.

I've got 230 kW on 16 psi and running the following mods.

Full RB20DET rebuild with upgraded rods and bearings

FMIC

Full turbo back exhaust with performance cat

Greddy Dump Pipe

z32 AFM

Cold air intake

Splitfire coilpacks

550cc injectors

Nistune Chip (on stock ecu)

Garrett GT28R Turbo

Bosch 044

Exedy Super HD Clutch

Would Pon Cams and an exhaust cam gear be beneficial???

James

Not sure about Pon Cams as I've never used them on a RB20DET, but an exhaust cam gear would be beneficial if you're chasing more low down power, just retard the exhaust 2~4 degrees to your desired levels.

Have a search on the dyno results, might give you more insight.

I'm guessing pon cams would further enhance the gains of an exhaust cam gear. Cheers bro

TBH, when I had pon cams on my car, I didn't bother with cam gears.. many have said Pon Cams are perfected, no need to dial them in. One or the other, not both... *waits for flaming*

Better just browing the dyno results to give you a better idea, remember top numbers mean sht when you've got a total lag monster.

with my Pon cams, in my 26, we left the exhaust cam set on 0. and did some miror adjustment to the intake side, as it gave me more response, playing with the exhaust side just made it real bogy down low.

gained mid range, and topend... did lose low end response, like under 4k it dosnet really see any positive pressure. it was only on 18psi, could have made abit more power but i was out of injectors.... we prob could have wipd it with more timing but i wanted it safe for trackdays/drags...

IMO it's a lot of money for not a lot of gain.

The only real place to spend money is on a bigger turbo and chase more power.

"Roy (troy)" put in some cams into his TD06/RB20 set up, and lost response, which i guess is the issue with most RB20's.

He went back to factory cams.

Alternatively man, if I didn't want to chase power and was after drive and feel, would it still be a bad move?

Well define drive and feel?

If you want the RB20 to have anything before it gets up onto peak boost, then IMO its a bad choice.

How often do you drive around foot to the floor? No often.

Yeah I adopt the give it a squirt every now and then. Most of the time cruising off boost with regular rolling boosts to the speed limit.

Drive & Feel: Responsive, direct, least lag possible, nice spread of power....and I will add...that pleasing lumpy nature of the engine note with aftermarket cams.

Please advise if I'm being a tosser lol

    • Well, my new WMI system took much longer to finalize. I actually missed my dyno appointment last Friday and lost my 150$ deposit. I'll be going back in the next week or two.  To sum it up. I only kept the AEM tank from my old setup. I replaced the AEM pump with a higher flow/pressure ProMeth 30GPH pump. I also swapped over to a 6AN low pressure feed line to the pump from the tank. There's also a pressure switch you cannot see on the pump high pressure line.    This is feeding 6x 200CC direct port nozzles and 1x 500CC Pre Throttle body nozzle. All fittings are Swagelok, because well why not. I also have a 300PSI pressure sensor up front.    I now have my Haltech ECU controlling everything. I start my pump with a basic relay at 5PSI and deadhead it. I then PWM a 3000CC methanol Injector to control flow starting around 10psi. The pressure switch in the trunk, along with my tank level are safeties before I ever get to 10PSI, and then I use my pressure sensor upfront as a secondary safety to cut the WMI and corrections in case the injector blocks or a line ruptures.  Wish me luck on the dyno!    
    • So, I'm back with bad news. There's no jack long enough on this planet that will reach the front subframe. If by some chance there is, it would weigh 200lb's.  I purchased a long reach jack... The damn thing weighted 120lb's and was massive. Didn't even come close, was still short at least a foot. It was a pain, but I brought it back. Next I decided HA! No problem, I'll get an Extra long reach jack. Well, I couldn't lift the box... It must have weighed 160LB's and luckily there was an open box in store. I took measurement and was still nowhere close.  Sadly I've lost hope and have accepted defeat. 
    • Thanks for that tip, niZmO_Man. I think the battery is OK. It's quite a new one, but I'll check. Last time I needed a new battery, everything electronic was fine, except that there wasn't enough current to turn over the starter. I decided to order one of the partial AV system translation CDs from Car Audio Workshop in NZ. That might have some effect, or help me diagnose the date problem. 🤞
    • I suppose it was relatively stock too, the JZ motor handle most mods thrown at them without even breaking a sweat 
    • I saw your intro update, are you sure you've actually had a starter motor failure? You mention it could be the alarm causing it. I'm assuming you've got a no start issue, but what are the exact symptoms, as there could be a few reasons it has stopped wanting to start.
