Why the need for a rewire?

Are you getting robbo to do the job again? He did that car not all that long ago.

He and Phil armour are the only two guys I know who have a good enough understanding of the motecs awd capabilities ( i know alot of people who hae tried and failed causing all sorts of damage) Have you considered talking to them about how the car was working before changing things or trying to improve on it ( knowing Phil and robbo I'd say that's not possible anyways)

If I was you I'd ask whoever is removing the loom to be careful and keep it complete, it would have been a tefzel/raychem loom that costs $1000's to have done. Robbo can be messy on some things but his quality of components is always top shelf.

Thanks for the advice... I agree with you 100% and am taking the car to Phil for this work, its already booked to go to him next month. I think he mentioned robbo as the guy who was going to help him do the work.

Reason for the rewire is that is has been a while (maybe 5+ years?)since the car wiring was done and there have been some adhoc additions

A complete rewire might not be required but we are seeing some intermittent problems with sensors and wiring hence I want to get it sorted properly. If Phil recommends a rewire then that's what it will get.

"Plan B" was to sell the old street registered car that was being setup as a track car and buy this one. The idea was to buy something that had all the goodies and a good setup and in the long term save some $$$... but as it turns out it wasn't so straight forward.

But eh, that's racing and cars!... its turning out to be a pretty major rebuild.

I'm hangin to get it out to the track but don't want to take short cuts !!

Good to see your using the right guys for the job.

A full rewire you'll be looking towards the 10-15k mark including engine loom and body loom but they will only use the highest quality tefzel wire, detusch connectors and raychem shrink tube.

Hopefully they can re use some of the detusch connectors you already have to keep the cost down.

We had a motec loom done in a GTR recently, wasn't cheap and the finished job was typical with some tidying up to be done but the quality gear was there.

Are you going to get Phil to tune it again? He always tuned that car when BSM were running it, between he, robbo and abe (the original engine builder) there is a wealth of knowledge about your car.

Armour runs a workshop that specialises in V8 supercars and the top end of the Motorsport market out towards Penrith.

Unless you have a high end GTR with motec gear and every component on the car is spot on your wasting his time trying to get a tune.

One of my customers who owns a very high end immaculate circuit GTR has his car tuned by Phil.

This BSM car was done by Phil back in its hay day. As was the sister car to it.

A lot of the Sydney based V8 DVS teams like sydney star racing, competitive production sports lotus' some Front running IPRA cars etc are done by Phil.

It's not a commercial workshop where you can show up and have a chat then get your car tuned.

Most people in the "domestic" market would never have heard of Phil armour. Most serious Motorsport competitors know who he is.

Yeah, I've met Phil a few times, he is a good bloke and although he is very busy still helped me out with a couple things. I did speak to him last week and he said that he will book me in early-mid January.

I think this was a good GTR in its day and this rebuild is heading in the right direction but I am not aiming to be competitive at Superlap and just want to get out there and have some fun then see what happens...

I have had some exposure to a couple race teams and have seen what is involved to get a car to the front of the field. I do not have the funding or the time to go all out with the car but I want things done properly... UAS have done a great job getting it where it is and will be doing all of the major mechanical work, suspension setup and aero..

As for tuning, Dave at UAS has done the initial tune on their 2WD dyno and the car sounds good on the dyno (a lot better when it has compression on all 6 cylinders). I'm looking to take the car to a mate of mine, Jim at Tunehouse, to double check the tune and maybe have a play with the cam timing to see if we can get it to come on a bit earlier ... he can also check the 4WD operation on his Dynopack dyno. I'll ask Phil to give me a rundown on the Motec 4WD control.

Did u end up comparing back to back results of the previous low mount system vs your new BW?

BW = Borg Warner??? No I've got a precision turbo...

I've got some old dynosheets from a dynapack dyno when the motor was good and I guess it would be a good comparison. I'll have to wait until I get it on the dynapack for a few runs then do the comparison.

great idea to get the tips from John Boston, he knows the car backwards as well.

Its going to be a different car once the suspension gets redone. The motor with a single will also give it a different feel but I agree johns input would be great...

Quick update... now much work has happened to the car. It is now at a Motec specialist getting completely re-wired. I just have to stay patient.

Still have a few minor issues to address as well as address any problems following the re-wiring and then get to the track for some practice to make sure thecar is ok before the Nissan Datsun Nationals...

Cant wait to get it out for a run ...

Sorry guys, I've been a bit slack, here is an update...

After spending 5 days rushing to get the wiring finished, get the boost controller and Knock box setup and then get it tuned and spanner checked I towed it to Phillip Island for the Nissan Datsun Nationals for its first outing.

First session out, practically the first corner, it spat the power steering belt and it knocked the dry sump belt off. The warning lights flashed and I switched it off. It had a wobble in the power steering pully and it did fall off a couple times during tuning but we tightened it up and it seamed ok... not!

We put a spare oil belt back on and I took the car out for the second session without any power steering... not much fun. Hitting the apexes was pretty difficult and having no feel in the steering wheel was not confidence building. I only got a couple laps in to get a feel for the car before the session was red flagged. At least I got a chance to bed the brakes in a bit.

Third session I warmed the tyres up and then decided to have a go... First real flying lap it broke 3rd gear !! Game over.

All in all I got about 5 laps none at any real pace but if you asked me whether it was worth it .. the answer is yes!!

The car felt great under power and flat changing up the gears (using the ignition cut on the gearknob) felt fantastic.

The car has been sitting in the trailer at home and I've been restricted to playstation by the missus for a few months.

I will hopefully get the box out next week and send it to a specialist to get sorted but the guys in the know are telling me to get a Holinger.

Yeah, that's racing... just need to sort it out. Dissapointing that the PPG gearset seems to have given up!?!

The engine felt strong and as long as you keep it above 5000 rpm it was very responsive. Actually it felt quite linear powerwise which was surprising. It did not come on like a light switch. It loves to rev...

Suspension wise it felt good...not hard and not soft. Can't wait to get it out to Eastern Creek.

    • Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.
    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.
