Depends what you want to acheive and on what mods you have done already. If you want more power up the boost. Poncams are said to run nicely on the Rb25DET but I'd rather spend the money on a new turbo. If you don't go for the cams an adjustable exhaust cam gear will give a small midrange improvement.

on a different note, you say you can improve midrange by adjusting the cam gears on an rb25? would this stop R&R on a standard turbo setup? i have mega R&R in midrange on anything above 7psi, would altering the cam gears help this? or just make it more R&R?

The short answer is no.

Unless you have a fairly big turbo GT3076 and up they dont make much difference.

I remember a few years ago on here, a bloke put some Tomei poncams in his Stock turboed 34 GT-T and lost power everywhere in the rev range, even after It was tuned to within an inch of its life.

Roy also went backwards changing to Apexi cams in his angry RB20

Are you referring to Bass Junky? Pretty sure he had poncams and got good results but got nowhere with adjusting cam gears.

Hi But he`s has 33 head not a Neo ,so can`t compair them,

for me keep stock get adj cam gear,

then save if you want CAM UPGRADE,

learn to handle what you have & then think what`s next.

Cheer`s Chuckie.

It depends what you have done so far. If youve done pretty much all the bolt on stuff and are looking for the next engine mod than yes the poncams are a good option. Thats what I did got all bolt on stuff done now going for some poncams and exhuast cam gear. But yeah as others said if you havent done the stage 1 bolt ons I wouldn't think its a good idea to do them.

Considering that you can get a genuine 500rwhp with standard RB25 cams, I dont think it is worth it at all unless you want more than that.

As for the Neo vs R33 setup, the ports are the same, valve sizes are very similar if not the same, only advantage between say a 256deg 8.5mm lift cam for the Neo would be slightly more agressive ramp rates on the lobes, and thats if Tomei even bothered to do that.

It aint about peak horsepower though. It is about gaining more power in the midrange which is extremely hard to do on a setup allready pushed to its limit.

Yeah thats my main reason for opting for a set of cams Im not concerned about peak so much, so once again it depends what you want and are aiming for.

    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
    • Well the articals keep saying a Q50s (Skyline in Japan) with a new Manual gearbox. I like the talk about the new looks with the round tail lights. I hope they bring back the retro look like they did with the Z

    • Wanna rewrite all of that in, say, 2 or 3 separate sentences, so that we can read it?
