Low end increases? Keep your stock cams then.

For mid-range increases, then 264 degree cams are the go.

The reason people talk about TOMEI poncams is because they are a direct fit (~9.1mm lift).

The HKS cams which are a direct fit are only 8.4mm lift, so most people just go for the TOMEI cams.

If you want to focus on low-mid range power i would try the new Tomei "Type R" poncams for GTR. I think they are around 252 duration, and very effective for low-mid range. Cam gears will also help bring boost/powerband earlier. I wouldnt do cams without out the wheels. I have Tomei type B poncams in mine.

The HKS cams dont have enough lift in my opinion. You would get better results with the Tomei's. Better to spend the money right the first time. I think its been proven many times that Tomei Poncams are the best cam solution for GTR. They run the most lift of all the "drop-in" type cams which i think is important when choosing cams. More lift equals more air to breathe.

If you just wanna shift your powerband earlier, get a set of cam wheels fitted and dialled in. This will bring power on earlier, but at the expense of top end power dropping off earlier.

so keep the standered cams and get some cam wheels?

but surely HKS is still better than standered?

Cos i doubt ill ever spend 1000 on poncams

Yeah, HKS would be better than standard of course. But the Tomei's even better :D ..Tomei's would give a greater peak power/torque throughout the rev-range compared to a similar duration HKS cam i think. (Which is the reason most do a cam upgrade)

What are the specs of the HKS cams you were looking at? Durations/lift specs?

Think about what your end result/goal of your car is, and whats gonna work better for you in the long run. If your on a tight budget, then there may be other areas of your car you can upgrade and get better value for $$$ per KW

Someone on the forum may have used the same HKS cams in their car, hopefully they will find this post and give an opinion from experience

its just i can get a set of HKS cheap lik 499 new

Brand new Intake & Exhaust side HKS cams for $499? I don't think so.

For your application the Tomei Type B Poncams are the best choice.

The Tomei Type B package that includes Tomei Duralumin cam gears is a very good option

We don't run any cams in RB26's without valve spring upgrades. The standard valve seat pressure is abismal, so the rule of thumb steps we use are;

Up to 9 mm lift = shim the standard valve springs

9 mm to 10 mm = Performance Springs, best value for money and shimmable to achieve the seat pressure desired

Over 10 mm = Jun valve springs, simply the best. Keep in mind the MINOR releaving of the head to clear the cam lobes (not a biggy, but necessary)

All of the above can be accomplished without removing the cylinder head ie; done it situ in the engine bay.

You want more low down performance, TURN UP THE BOOST, nothing else works as well and is that simple.

Happy New Year

Gary

Dont Forget the new GREDDY easy cams, direct fit, supplied as a matched pair with all the centreline checked so that they (in most cases dont need dialing in) , cheap and all have new profiles ground off a brand new machine. 256 9.1mm lift or 264 9.1mm lift available.

my cars stockish.. has a trust intercooler, n1 turbos and triple plate clutch...

Buying

Turbo back exhaust (unsure what diamater yet or twin/single. ideas?)

Power FC and controller

Boost controller (the add on one to the power fc)

Apexi intake...

then i have around 500 left and thats what ive talked my mate down to wid the cams..... 500 better spent any where else then??

^^^ good call, with your setup ADz you should see reasonable power as it is with a decent tune.

oh hey ive budgeted for a tune, sorry didnt put that.. still have around 500 left over... cam gears worth it on standered cams?

what kws est would u think that set up could make>?

Hi there, just a dumb question if it hasn't already been asked, $499 quoted is for HKS cams or HKS cam gears only?

Cheers GW

    • Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
    • And now the bloody flapper is jammed slightly open. Lazy as all f**k in 3rd-5th (very hard to convince it to make much boost before you run out of revs), but will make 12 psi in 1st, which shouldb't be possible with a 5 psi spring and controller set to <10 psi. Methinks I'm lucky it jammed where it did, rather than fully closed. It's actually a well weird situation. Careful examination of what's happening in the back of that housing when the gearbox comes out and all the other stuff (injectors, AFM retune) is supposed to be done, next week.
    • The powder coating came in at $250 EACH. The TRX rims got a coat of clearcoat on the outside only.    
    • Bit wet, but YUMMY
    • Keeping in mind that I am currently getting flat 10 L/100km on my RB25DET, which means >>500km/tank. I would test this car for vacuum leaks, check codes and AFM signal with NissDataScan as D says, check plugs, do a compression check while they are out.
