I'm rebuilding my head using Supertech valves, hydraulic spring kit, seals, valve guides. I'm also rebuilding the bottom end with supertech pistons and eagle rods N1 oil and water pumps.

I'm running Nistune with an Rb20 ECU, so I don't have VCT, I want to buy uprated cams, should I buy the Tomei pon cams or the Greddy easy cams for the VCT or use a different profile cams and remove the VCT?

If which would be the best and reliable set up for a 500 to 600 BHP car, daily driver a lot of autobahn and some track.

You have to buy a seperate controller or alternatively swap your ecu for a Z32 one I believe and stick your nistune chip in that. There are a few tricks to it which i don't know (try searching). Better still would be a Link ecu which will also control the VCT :

A cam gear on the exhaust cam is not an alternative to VCT - ideally you would do both.

advance up the intake cam with cam gears if not running vct it will help alot.

I got good results with 256 degrre 8.5mm lift, i think i ended up around 8 degrees advanced on the intake..

here is the thread http://www.skylinesaustralia.com/forums/Rb...ft-t308743.html

using this diagram, I beleive I have to connect it to pin #113

Also, which Tomei cams would be better? Is it only one type for the RB25 with VCT and Hydraulic lifters?

Or what about the Greddy easy cams?

Pon cam for vct and hydraulic lifters. Two types for series one and two.

Trent did you try variations on total increase in overlap? Eg IN+4, EX-4? Still gives you 8 degrees but I'm interested to know how it affects the torque curve.

Using a Tighe grind on my 30/25 and it seems that there is a point where the mid range is noticeably fatter but torque at the top end falls away and you end up short shifting a bit. Note this is a bit of subjective feel, trying a few settings on the road before slipping it onto the dyno.

    • @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man
    • Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?
    • Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
    • Assuming your brake pads are not worn right down, I'd add a little brake fluid. Is there any sign of a brake fluid leak?
    • Hello all,  I need of some help. On my drive home my handbrake light lit up and started flashing. When I got home I checked my handbrake sensor under the centre console and nothing seemed out of the ordinary. I have scanned my car via the consult port, no codes shown. Checked my brake fluid as well which is half full. Tried unplugging the brake master but it didn't change anything. Thoughts on what it could be? The master float doesn't seem to be stuck. My car is an 1998 ER34 sedan GT. No hicas but has ABS Photos below 👇🏾
