I am no expert, but yes, Relays do deal with high voltages. if there was a short in the relay, it might melt the relay, melt the relay holder, melt things around it, but it wouldn't be enough to melt things on the other side of the engine bay. The only way to get that kind of heat and fire damage to...

If it was a fuel leak which was ignited by an electrical fault, it is still his fault since he would have done the fuel lines. I am not 100% sure, but I don't think a faulty relay would do that much damage. But yeah, legal way is the best way. Even though it wouldn't be as satisfying, it'll still be...

Simmons B45s I think. Good luck with what ever you decide to do though.

The IRS should mount to the Aus-Spec Sigma. You might need to weld in rear strut towers for the rear shockers. But, wrecking the car isn't the answer. Flav fixing it is. If you were wrecking it, I'd like the wheels, but you can't wreck it! It is such an awesome car!

He was the last one that was working on it before it caught fire, and if you did no work to it yourself, or had anyone else touch the engine bay, then it obviously is something he did. It's not like your car was on fire, or caught fire, before Flav worked on it. I can see now that even before you ge...

First line on the left is the surge line, when boost starts. Middle Line is max boost. and right most line is the choke line IIRC. The calculations I use were based on what was said at the Garrett website. After seeing the quad turbo thread, I was thinking that the turbo charger I have lying around ...

OUCH! I would be completely devastated if it happened to me. Hopefully it is repairable and you get compensation for it.

This is the maps again, with my data plotted on them:

As a base to work out flow rates etc. to match my engine to a turbo charger, I went with ~8 PSI (apparently for ~160kW), 12:1 air/fuel, and of course a 2.6L engine. Numbers I got were 1.63 Pressure Ratio, 13.95 lb/min (201.88 cfm) @ 2000 rpm and 23.65 lb/min (342.25 cfm) @6000 rpm. I think the SOHC ...

Thanks for all the info. I am going to have to cut out the remaining 3 screws as I have stripped them. But I will get one of those impact screwdrivers for next time.

At the moment I am having trouble with the throttle body I picked up from U-Pull-It. I have been trying to remove the fast idle air valve assembly from the rest of the throttle body so I can give the rest of it a good clean, and get a closer look to how it all works. The trouble I have been having i...

Selleys No More Gaps? That wont work! You need duct tape, it'll fix anything on a car.

My plans for my EFI conversion on my GN Sigma is I am using the 2.6L block it came with, putting on a Magna head, and keeping all of the emission control devices. I am going to be using an aftermarket ECU, but it is still possible to do it. The conversion I am doing is based on a TR/TS Magna, but th...

I think the serial number on the block says what year it was made.

Do you mean a 1983 Sigma, or a 1993 Magna or a 1993 US Sigma (which is a Magna anyway)?

i would be careful of the chinese ebay units, i have heard some of them come with free compressor wheel blades for ya intercooler :shock: Better the Intercooler than your worked engine. Even if you ran a small cheapy intercooler between the cheap or expensive turbo and the intercooler, safe guard a...

The TD05 look like a good option. It also looks to be cheaper than a disco potato. This would be good since I am on a shoe string budget. I also have some time to make a final decision since I am still in the middle of converting my Sigma to EFI.

That does look familiar. I picked up the car from just off Kilkenny Road IIRC. Since it had a tighter accelerator cable than my Sigma, I accidentally spun the wheels in the drive way.

I can't remember, I think it might have. I thought I had an engine bay pic of that car, but I can't seem to find it. I do remember it had a ram-flow air filter though. It also had power windows and central locking.

My past rides : 1968 Ford Cortina MKII http://users.adam.com.au/cottees/sigma/PIC_0011.jpg I was given this car for free since someone I knew wanted to built it as a rally car, but didn't have the time. I ended up not having the time or money to be able to fix it, so I ended up selling it. late 1970...

I did a heap of math using the guides and formulas on Garrett's website, and it looks like the Disco Potato would be the perfect match for the 2.6L. Now that I have decided on a turbo, I just have to try and afford it. I have plenty of other things I have to do first on my Sigma, so it isn't too muc...

I can't see why not. If you have a donor car, it would be much easier to take all the running gear from the Magna, and drop it into your Galant. I would recommend getting a Service and Repair manual for a Magna TR/TS. I would give it a try, and if it doesn't work right, you should be able to take it...

I have done even more reading over at www.megamanual.com and it shows that MegaSquirt II has 7 pins spare to use at outputs that can be activated or deactivated depending on what the other sensors are reading. This would be handy to keep the purge valve working, as well as using one to activate the ...

I have been doing some more reading, and it looks like that the stock ISC/IAC valve on the Magna TR/TS throttle body could be used. The GM IAC valve I think everyone has been using is a 4 pin bi-polar motor where as the one on the Magna is a 6 pin uni-polar motor. From what I can see, the uni-polar ...

I was just googling for Digital Dashes and came across a thread from the old site : http://www.sigma-galant.com/archive/modules.php?name=Forums&file=viewtopic&t=4783&view=previous Answered 2 questions I had. Looks like that the Magna speed sensor will bolt straight to the jap 5 spd. it a...

Yeah, gotta see pics. Especially the IRS.

I was thinking about making fibre glass panels for my Sigma GN. Because of fibre glass panels being dangerous in an accident, I thought about that you could integrate weak spots into the panel so it'll crumple rather than splinter. As for the doors, I would take out anything that is not needed that ...

I have a stock TR engine loom at the moment, but I am yet to do anything with it. If I am going to go straight to a Megasquirt, when I modify the loom, I'll do so with Megasquirt in mind, instead of trying to get it to connect to a stock ECU. I probably wont be ready for the ECU for 2 months+ anyway.

OK, sorry, but I usually don't have time to look at a shift light anyway, I just change gears when it feels right !! :) you dont need a shift light I agree. If you know how to drive, and know your engine, you don't need some light to tell you when to shift. Get to know your car and save $270. The d...

Doing a bit of research about the Megasquirt and the 4G54 stock sensors from the TR/TS Magna. Distributor - I think you can use the Magna one as a crank angle sensor. Air Flow Sensor - You can get Air Temp and MAF readings from it. MS can do MAP or MAF, just have to change the settings. Throttle Pos...
