So since this thread is dead...can we take it in a slightly different direction. Copy, complete and paste the following info into your post :ninja:

Cam Brand -

Specs - (I:Duration/lift , E:Duration/lift)

Turbo -

ECU -

Before, Power - @ psi

After, Power - @ psi

Dyno sheet

It seems so far a few ppl seem to have tried Poncams and HKS Step 1. I shoudl have some results up in a few weeks.

Cam Brand - Tomei Poncams

Specs - (I:256/8.5 , E:256/8.5)

Turbo - gt2876r .64 housing

ECU - haltech e11v2

Before, Power - ? @ psi - didnt get a power reading before doing all the work to the engine

After, Power - [email protected] psi

Dyno sheet - dont have a scanner

quincy777- mate ill tell you this. i have had an RB20DET in my GTRST b4 and the mods i had was:

Custom Zorst Manifold

GT3040R with .63 housing

Sard 550cc

EMS stinger

bosch 910 fuel pump

forrged pistons (Arias)

Custom FMIC

Now, i was running 1.5 bar of boost and she made 230rwkw. I ordered Tomei 256 with 9.5 lift cams that was for an RB25DET engine and my mechanic fitted them. then car was tuned at 1.2 bar boost and made a 261rwkw.

The point is that i invested $1500 that was NOT a waste.

Cheers

Babak

230rwkw on 1.5bar wtf that sounds like a fair average figure for that setup...

Who tuned the car? Have they any experience with cars with the same setup as you less the cams?

I have searched high and low and im not able to find a single definitive example where a setup had been run for a period of time, then had cams thrown at it and tuned by the same guy on the same dyno and actually made more power.

LOL...it doesnt appear as though such an example exists :)

If you were after an rb25 example i meet all those criteria. 30rwkw gain with no other changes.

it was tuned by richard at allstar performance systems here in qld, your best bet would be to email dan from elite racing at [email protected] and ask him about his personal rb20, i know he did see results from changing to poncams.

I have Cams in my RB20, with GT3040, 25psi, boost came on hard and all the way to 8.7k, made close to 290rwkw untill it received some forged piston melting conditions. lol.

a better tune and more fuel with new engine should see it hit over 300rwkw.

i know this is all about cams but im not for giving out my specs, but yes they sure make it alot better. more power and response and yes the cam gears were adjusted.

have some faith troy.....my car is in the shed with its cams out, ready for the new ones (256/8.5)....just waitin on the water pump, belts, tensioners

should be fairly soonish

LOL...fair enough. But there is enough 'trust me..wink, wink" stuff going on. Im looking for hard tangible results :)

Can you at least post a dyno sheet?

Look forward to seeing your results as your turbo is a bit smaller then what im running.

Honestly. Based on my experiences with my setup...i agree. Its all in the tune and being willing to run the 18psi with a decent turbo.

What are std Rb20 cams and std RB26 cams. Sure the lift is a little different but the durations isnt overly different. So perhaps the std Rb20 cams are decent enough. I know my power whilst trailing off up top didnt exactly fall over

so true, if anything the rev limit needed to be raised

would obviously differ between setups, but goes to show its possible

anyway, graphs have been pissing me off as of late, going to WSID on the 25th.

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
