PON CAMS V CAMTECH 272

Hey guys,

Hoping someone can point me in the right direction with either or link or shedding some light on my next modification. I am looking at purchasing Cams for my R34 GTT already pushing 330RWKW, can any one let me know what the cons and pros are going with Tomei drop ins 260 as oppose to the Camtech 272. My 34 has the following modifications:

 1000cc Bosch Injectors

- Walbro 460 Fuel Pump

- Full Turbo Back Exhaust 3 inch

- Custom Dump pipe

- Garret 3076 Turbocharger

- Power FC ECU tuned on E85 ( UniGroup Tune)

- Greddy Electronic Boost Controller

- Tomei Head Gasket

- Screamer pipe

Would be good to get some ideas on what would be best for my setup and why as well as knowing which one would sound better on idle :P which is just a bonus.

 

Thanks peeps.

what are you trying to do for starters? 

do you want the torque to be more linear or do you want to stretch out the power band or you're chasing a few kW up top or you just want brappy cams fordaslarts? 

And I wonder how that timing map looks like :)

If you're after fappy brap brap noise, go the cheapest 272 cams you can find with or without VCT support. 

if you want something that works, without the brap and not losing down low get the Tomei Poncams with VCT support.

I'm looking for both benefits, performance and the Brap brap, tuner has advised 272 Camtech - what performance differences would i see with the 272 as opposed to poncams ? @Dose Pipe Sutututu

Edited by cesar34

you will make more power with the 272 however you'll notice your turbo will be much lazier coming on as you've shifted your motor's efficiency to the right..

depends how you drive it, and the car's intended usage.

Poncams will suit what you want performance wise then get your tuner to use rotational idle for lumpy lumpy sound

sounds nice ! but wouldn't that also be due to your side pipes that is quite loud ?  @bcozican

Sidepipe makes it louder and crisp but idle it idle if your going to run a muffler etc its always going to be toned down

 

Ive run 500-550 rwhp on rb25s with poncams both with and without springs. Mose well go springs if you can

what did you find the difference to be from stock cams to poncams ? and whats the most 'legal' looking way to get them to sound more aggressive, simply removing the muffler ? 

 

thanks heaps

to be honest Ive never had stock cams always had poncams straight off ...  but if you look at all the results poncams on average increase your torque a bit and mid / top power a bit and move the curve to the right just a bit

 

I say bit ... because every car engine is a little different

 

Sorry don't know how to best do it 'legally' as Ive always had straight through pipes but Id say taking your muffler off is one of the least legal ways. By my thinking maybe just rotational Idle ... but it will just be dampened a bit compared to not running a muffler. Still get lumpy etc but nothing is actually illegal especially if  you still come under the legal DB reading.

one of the end goals as well is trying to figure out ways these GTT skylines can beat your 280kw Evos, before i make a new thread any sort of suggestions ? i use to have an Evo and got the right offer for it so i chose to give a skyline a go but seems to struggle to beat 300kw Evos ?

 

thanks @bcozican

Beat them at what ?? street, track, drags ?

Not really comparing apples with apples but your GTT is more than capable or at least very close to it and it all depends on budget. I don't have no ever driven a 4wd / awd car but from reading bang for your buck they are hard to beat so hazard a guess you'll have to spend 'more' on the gtt to be the same to compensate for 1) new tech and 2) rwd vs awd

There are a number of threads in the motorsport section and projects and builds section where specifically gtt's but other rwd skylines have been developed to the point where they'd match evo's and the like so take what you can from those also.

You have enough power so it comes down to :

Driver skills / seat time

Brakes

Suspension

Tyres

Weight

Work out your budget and get the 'best' you can get of each of those as you go and it'll go a long way to where you want to be

awesome man, looking more in the roll racing rather then track, driving an Evo before i definitely know that around a track they have the upper hand ! but down the straights they are still quite competitive @bcozican

    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
