Pon Cams And Exhaust Cam Gear On Rb20Det

[Plan-FAILURE]

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???

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.

Ahhhhh I see. Might just opt for the pons then.

Will check out the dyno results.

Cheers bro.

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.

Cool.

What gains did you get with the pon cams on the 26?

[Deano 1]

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?

[R31Nismoid]

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
