my understanding is that the 1.5 does not have the later model rb25... not sure how you'd find out! Maybe post it somewhere?!

i bought a rb25 heat with vct how can i tell what series it is ? all i got was the head and cams no covers or manifolds

no idea dude! maybe post it in the forced induction section?!

So not to waste time for you moanie pie,

People these cams can only be fitted to a RB25 built from sept 97, i have a 97 S2 aswell but was built in march and these don't fit, already did the research. Ohh and if your wondering what the diff is, its something to do with the crank angle senor or something like that. Other wise i would've snapped these up myself.

Would fit mine then, but i dont know enough about them to consider them as a worthwhile investment.

Phil, great upgrade if you ask me. Do yourself a favor and talk to craved about these, he'll be able to tell you anything you wanna know.

So if you have an S2 R33 pre 97 you would need to change the crank angle sensor, correct?

The nengun website says these will suit an S2 dosen't mention the year...

It does say on the Nengun wesite:

ECR33: 1st;1993.8 - 2nd;1997.9 - (changed crank angle sensor)

And a description on the cams:

Generally, engine tuning is to modify the torque characteristic of engine by changing cam duration timing and height of the cam lift, so as to gaining maximum torque and horse power. However, when tuning the engine strictly, it should be carried out with the idea of securing effective area of the valve not only by duration timing and height of the cam lift, but also by through improvement of its intake efficiency. High valve lift allows huge amount of air to flow in, yet it mechanically damages the system and gains friction loss. Also, wide cam duration will deriver great power at high RPM, but it gives rough engine character at low RPM too. Tomei have worked to get an ideal well-balanced profile of camshaft and succeeded to give it 1.3 to 1.5 times more effective area than regular camshafts

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
