Nah pretty sure that had slightly touched sticks.

But yeah 400rwkw on stock cams can be done, I've made 370 and I've seen others make 390-400 as well with -5s so they are working pretty hard. With a turbo that big it'll be easy.

Exactly....it makes 10+psi @ 2500, hence the big torque early.

Some more details:

Crank is a custom billet 12 counterbalance job. Don't try to rev those RB30 cranks too high!

Rods are SR20. Don't sweat the R/S ratio. 1.5-1.65 has proven to be ideal/desirable for a 4 valver in the 1-9000rpm range.

Modern materials and rod/piston designs mean longevity is not an issue, and shorter rod is a stronger,lighter rod.

Pistons are custom.

Camshafts are Nissan OEM.

Turbos are currently Garrett -5's, (about to make way for a very slightly bigger set).

We have now have it tuned at 24lb and it makes 468kw with plenty more through the mid-range.

I'll post a new dynograph when I get a chance.

Lots of sneaky tricks in this one. I probably shouldn't have sold it after all..... sad.gif

cheers,

I'd guess stock cams but could be wrong

I dunno I've heard guys making good power w stock cams.but really they are designed to maximise a 2.6 ltr. 3l need to breath.

I didn't make much power w stock cams. Maybe it's my setup I dunno.but I Don't care about power figures.as long as car rips I'm happy.

Btw I gained 50kw just w cams.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Any number of different ways. Have the coils draw sufficient current to provide contact wetting. Use different contacts in the switch, either by material or design, better suited to the low current drawn by a relay coil. Etc.

      Hmm, how does the R34 manage to have headlight relays then without getting excessive carbon buildup on the headlight switch contacts?

      Not R7R. Meant to type R&R, obviously enough.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.

      R33 headlight relay conversion?

      I was poking through the R34 wiring diagrams vs R33 and noticed that the R34 has proper headlight relays while the R33 is like the R32 and sends full headlight power through the headlight switch. I'm not afraid of wiring but I really would like to do this in a way that looks OEM (clipping into open positions on the OEM relay box) and also unlike the factory wiring which interlocks the high beam and low beam on the halogen series 1 GTR headlights I want to make it such that turning on the high beams keeps the low beams on as well. Any advice on how to locate the specific connectors + crimp terminals + relays I need? I was thinking one NO relay for low beams and another for combined high + low running off the factory high beam headlight connector. I don't really want to splice into a crusty old probably discontinued factory harness so fully reversible is my goal here.
