Does your car run out of puff at 7g because of the Standard cams? Or are the -5's big enoug to give you power all the way to 8g.

No, it still pulls but I just dont seem to need to go much more before changing gears, with the -10s and cams it was ideal to gear down to 2nd gear at 100kph (has PPG gear set) and take it to around 8500rpm before hitting 3rd.

Now at 100kph it feels better to gear down to 3rd gear were it pulls hard and smooth, less work on engine.

^ missed earlier post... Stock cams, -5s... I went to 8,500rpm day in, day out too. Didn't nose over heavily.

My dyno reading only showed up to 7200rpm , I noticed a slight drop just after 7150rpm.

Got 8500rpm no problem, just pulls nice changing from 7

but was it still making power......more rev's don't show power. The only time you should need an over rev is if your gear ratio's are set up wrong for the track.

But you already knew that because your no simpleton aye!!!

anyone know what max lift is on stock 26 head?

With a reduced base circle, I had jun 264 9.7mm, fit in the stock head. This would be close to the maximum lift before relieving was required.

Anyone know of larger lift cams to fit stock head?

Sorry to hijack this thread.

I am in a similar situation with TS, and I was recommended the Type A cams instead of the Type R cams.

Anyone has any experience with the Type A cams.

I'll be running on 87mm custom pistons and conrod with HKS GTss turbos.

I am also looking for low-mid range performance as it is more suitable for my usage.

Thanks.

I've seen on my 34 the difference from going to type Rs from type Bs and it was a fair bit, same peak power but every thing happened 800 rpm sooner give or take

Type A's have a 256 degree exhaust IIRC.

Want low end? Type R's.

Make sure you post a graph !

I'll try to remember!!

I was looking at rhdjapan and I saw that they have a package for the poncams with adjustable cam pulleys.

funny thing is, the so-called special package is more expensive if I were to buy the cams and cams puley seperately. wonder why they calling it a special package ....

I am now using the oem cam pulleys. so should i be getting the adjustable cam pulleys too? what's the benefit other than the ease to adjust and the lighter weight?

Thanks

Sorry to hijack your thread, but I am in a very similar situation.

Has anyone had any experience or know of anyone who has used adjustable cam gears on aftermarket cams?

I am also looking at a cam change on my car but am in two minds about whether to have a shot at dialing in the existing Tomei cams (Type B) or just ditching them and going back to stock and dial those in instead.

The challenge I have is that the HKS2530's I am running are a bit laggy and, short of going -5's, I need to do something to bring my torque back down the rev range and bring boost on a little earlier.

I can see three options for me...

1) Keep Type B cams but install adjustable cam gears

2) Go Type R cams and adjustable cam gears

3) Go stock cams and adjustable cam gears

Thoughts?

I will post up a dyno graph of my existing set up tomorrow.

    • GTSBoy on your suggestion on another thread I had a look at those injectors and ended up getting them because of the quality.  Got the expensive ones.  
    • Hey guys been looking everywhere to try and find the correct gtr hood latch support part number but only found the first half and when I search with that number it sends me to an r34. The first part I found was 62515. If anyone could help me with the rest then I’d really appreciate it. Or if there’s some alternative hood latch support that would work even better cause I can’t find any for sale. (Searched on upgarage, partsouq,buyee,rhdjapan) 
    • If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
    • I have a heap that i have collected if you want some authentic ones still. Pm me if your interested!
