A 2530 isnt all that different to the std turbo. (yes i know it will make a bit more power, and probably come on a little harder then std as well...but in the world of turbo upgrades it is pretty close to what the std turbo will do)

Thats not to say its a bad choice. Just that i would perhaps think twice about throwing $900 cams at en engine using a turbo as small as the 2530.

That said a friends R33 use to use a 2530, it had baby cams and a greddy manifold and it was still the best, and probably one of the quickest street cars i have been in...it was also damn quick as the track the couple fo times he was good enough to swap keys with me.

C'mon Troy!

A 2530 is heaps different to a standard turbo. Just cos you can find someone with a stock turbo making 200rwkw and someone else with a 2530 making 220rwkw doesn't mean that the second guy wont shit all over the first. We've all seen 2530 powered cars beating much higher peak powered cars.

Sorry, i didnt really make myself clear. What i was getting at was perhaps you should think twice about using cams with a 2530.

I would highly rate the 2530 on the RB25. Like i said a friends old engine ran that setup and it was a briliant street car and very quick on the track.

What i was alluding to with regards to the size of it and the size of the std turbo is...ppl have shown that cams on a std turbo engine doesnt really do much at all. So was just cautioning that with a little 320hp turbo slapped onto the side of the RB25, cams may not give you the result you hope for...

As for 2530 on RB25...just make sure you have good tyres and suspension because they come on hard, and do everything you can to open up the exhaust as they tend to dropa few psi up high in the rev range

Ahh, that's a fair enough comment and may be true. I don't know anyone with a 2530 and cams but perhaps the higher boost capabilities would make them worthwhile where they are not with a stock turbo due to the boost restrictions imposed by it's fragility.

If looking at highflows check out some of the threads on them where we discuss the R34 and VG30 exhaust housings and how they are bigger making a highflow one of those better than a highflowed R33 turbo.

But that requires new manifold, an external wastegate...a hell of a lot of attention and expense for insulation of it and protection of all the engine bay ancillaries. Not saying its a bad choise, but a bit overkill for the power he is after .

Are you talking about the KKK or Garrett, cause the GT3071R needs no mods like that.... compariable to the HKS GTRS

    • Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.
    • Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!
    • Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers  
    • This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?
