Ive also considered this upgrade but unsure if the benefits are worth it? currently 340kw at wheels thru a gt35r.

house mate went 272 camtechs with precision 6765 and makes over 500 atw but the idle is just so angry its unreal.

256 tomei seem so popular?

There popular because there direct bolt in, retain vct and are big enough for most setups without having to have big compromises when compared to stock cams so good alround performance gain.

Hey guys, I'm in the same position as the op and thought I'd join this thread instead of starting a new one.

It's an rb25 in a 31 making 300kw @ 18psi.

Would a set of 264's be a good choice? This is what I've been leaning towards.

It's a daily but mostly just for fun (don't mind losing a bit of response and torque for some good 4000rpm+ gains).

Obviously I'd get cam gears and valve springs to suit, what company would you go with?

Cheers in advance.

As above - go the Poncams, keep the VCT, forget the cam gears or get an exhaust only.

dont know what turbo you have but a smaller rear housing and upgrade to e flex would be alot more beneficial than cams i think,

Im still not sure if the cams are a good thing for upto 300kw, could possibly create a bit of lag.. no arguments after 4000rpm though, on the streets where revs are usually below 4000rpm the cams might not be such a great thing

The Tomei Poncams are great value for money..... Mine and Ian's setups are near identical yet i have cams and his are stock (This is NEO so still relevant as a comparison i guess), he makes peak power of 345kw i make peak power of 360kw and the boost curve looks very very similar however i think mine has a touch more midrange. My car idles like its dead stock as the idle is set at 900rpm and there is no lumpiness or anger to be heard. YES i have a HKS exhaust cam gear too.

has anyone done before and after runs with/without cams?

im interested to see the actual difference they make, just upgrading cams

Thats what i was getting at above man, our setups are nearly identical.... The only difference is the cams (actually i have a full exhaust which may hold mine back a little) but it shows the power does increase with no loss of response as far as i can see.

ahh cool! so what about below 4k? before/after?

Mines not that exciting below 4k, yours will react different I reckon BUT I reckon it'll be an awesome addition to your setup :yes:

I run a ported 25, with t04z and 1.05 rear, I dont get my boost on hard till 4800 rpm, im hoping cams, and a .83 rear will bring it hard from 4k. which is what i want. Im not interested in twisting the earth at 3000 revs...

Why do you have a TO4Z and your only making 338rwkW?

Well I bought the whole top end second hand, and I plan to get it on e85 in the next year or 2 when its available and do few more supporting bits for around 380-400. I love the oversize turbo, I get killer economy, its safe in the wet, and i get great top end. When it was bought 1.05 rears were only available. It'll be a bit snappier with a small housing.

    • To expand on this to help understanding... The bigger/longer the block is, the more it's going to work to sit on your far away high areas, and not touch the low stuff in the middle. When you throw the guide coat, and give it a quick go with a big block, guide coat will disappear in the high spots. If those high spots are in the correct position where the panel should be, stop sanding, and fill the low spots. However, using a small block, you "fall off" one of the high spots, and now your sanding the "side of the hill". Your little block would have been great for the stone chips, where you only use a very small amount of filler, so you're sanding and area let's say the size of a 5/10cent piece, with something that is 75*150. For the big panel, go bigger!   And now I'll go back to my "body work sucks, it takes too much patience, and I don't have it" PS, I thought your picture with coloured circles was an ultra sound... That's after my brain thought you were trying to make a dick and balls drawing...
    • Oh I probably didn't speak enough about the small sanding block for blocking large areas.  In the video about 3 minutes in, he talks about creating valleys in the panel. This is the issue with using a small sanding block for a large area, it's way too easy to create the valleys he is talking about. With a large block its much easier to create a nice flat surface.  Hard to explain but in practice you'll notice the difference straight away using the large block. 
    • Yep I guessed as much. You'll find life much easier with a large block something like this -  https://wholesalepaint.com.au/products/dura-block-long-hook-loop-sanding-block-100-eva-rubber-af4437 This is a good demo video of something like this in use -    You have turned your small rock chip holes into large low spots. You'll need to fill and block these low spots.  It's always a little hard not seeing it in person, but yes I would go ahead and lay filler over the whole area. Have a good look at the video I linked, it's a very good example of all the things you're doing. They went to bare metal, they are using guide coat, they are doing a skim coat with the filler and blocking it back. If what you're doing doesn't look like what they are doing, that's a big hint for you  
    • The odometer does go up when driving.  Does this tell it is an issue with the speedometer itself?    Where can I look for replacement cluster? Or speedo? I can likely do the repair.. Will ER34 cluster work on HR34? Or do I need a HR34 20GT S2 specifically lol   
    • Mine's a bit bigger at 70x150mm roughly. The spots are flat, just can feel the edges if I dig my nail into it. I did fix some other other ones by both using my finger to sand that small spot (I'm a bit wary of doing this and creating hot spots and a bigger mess) and I also did sand over it flat and others, but this also worried me a bit because if I create an overall low spot on the panel on paint that is good.  Correct me if I'm wrong but as long as it's flat even if I can feel the edges, I can put filler because it will all be level once I sand it? I can see myself going in a circle after sanding guidecoat with 320 grit if for example the panel is flat with my hand but because I sanded the guidecoat I could have created a low spot again somewhere. Unless where I'm going wrong is what I mentioned previously where I didn't go low enough on the grits. It's 1 step forward and 2 step backwards here haha. I'll probably need to experiment with it more. Last time I go back to bare metal lol.
