Now i know that the center locks arent, but would the double wishbone setup be "street legal" in a sense if you could get it engineered?

Yeah 100% it an be engineered. Suspension modifications can be engineered as long as they are designed and fabricated to a standard the engineer is happy with.

I've only done 1 GTR that's been engineered we made some minor changes to satisfy the engineer.

Troy I do still do those hicas rear ends, the design has changed slightly to make them easier to fabricate but essentially the same components.

Its been a while as weve been flooded with work before the Wakefield 300 and the begining of the motorsport year begins.

Last weekend we competed in the Wakefield 300 endurance race along side PIstore in an S15 that we built and prepared for production car racing.

The event went well before the poor little factory SR20 threw a rocker arm and ran on 3 cylinders 94 laps into the race.

Great event we will certainly return next year for another crack at it.

The way I rather do them is from the lower rear seat belt mounts

It's a case of remove the rear seat, bolt the harness bar down and do the track day.

Remove harness bar seat back in and back to normal.

Problem is those upper seat belt mounted ones create a dangerous lever when you pull on the belts.

They swing downwards in an arc allowing the belts to loosen.

The idea of those bars going down is to try and prevent that rotation. They just bend.

I don't have any photos of mine but they pull directly against the bolt holes with no rotating forces

I can see where you are coming from with that. How much would it be for the harness bar with both the back seat and top bolt mounts.

I like things to be secured properly when they are in so the more points I can mount it to the better.

I wouldnt mount a harness bar from the rear seat and upper front bolts, its way to over engineered for how simple a harness bar can be.

For an R33 a harness bar done from 4130 chromolly tube ready for you to remove the back seat and bolt in they are sold for $330inc gst.

Always up for some alloy engine bay work and subframe mods.

We are expecting our 1st baby to arrive early April so I haven't booked much in for next month which has made it easy to be picky with work.

Let me know when you want to get it done and ill accommodate it.

    • After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive 
    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
    • No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.
    • Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
