Poo-Man's 1981 Mitsubishi Sigma Turbo


Recommended Posts

cheers, after googling the shit out of 'down sides of heat wrapping exhaust manifolds'.

it looks like i am not going to wrap the manifold.

i would be rather fucked of if the manifold cracked due to the pipes getting to hot and metal crystalizing and going brittle.

Yeah, I've still got the old airbox/airflow meter.

The old loom is still in the car. The car should be getting some work done on it in the next coming weeks. One decision we need to make is weather to use the old loom and splice into it or full rewire.

If the old loom isn't needed I'll get in touch.

the manager at HPC is a good friend of mine. I havent got the bill yet.

the price list is herehttp://www.hpcoatings.co.nz/PriceList/tabid/32273/Default.aspx

The quality of the coating is top notch. and i dont think my clutch and brake master cylinders would withstand the heat from the new exhaust and turbo, without the coating.

looking forward to firing the motor up!

I swung past TTT on the way home from work and put the reduction starter on.

And it burped into life for a couple of seconds!

Obviously the config in the ECU needs changing, as it won't idle or rev.

Dion from West Tech is going to help us on Saturday. Then road tune!

Soooooooo good to hear it run again (all be it for a short time).

Its reasonably quiet, which is good.

I can't wait for Saturday.

Just an observation but wouldn't there be a chance of the pickup getting pulses from the cam pulley itself? It's a bit hard to tell in the pic how close they are together. Can you configure the Link to work okay with the speed the cam pulley is turning?

For dyno tuning I had good results from Soichi at ST Hitec and mixed results from Auckland Performance Tuning in Papakura.

Yeah the link trigger wheel is close. But there is a small gap in between. And we can't use the cam pulley as a trigger for the link. It has to be a 24 tooth wheel with one tooth removed.

Thanks for the suggestions on dyno tuners. I will check them out.

Cheers ears.

yeah, i havent thought that far ahead.

so, maybe convert the front to 5stud.

or change the diff to 4stud.

I'll price it up and probably go with the cheaper option (4 at the front and 5 at the back.....hah haha haha)

cos my budget is well and truely blown out of the water. whoops.

Cheers for the link Phil. I'd been on that site ages ago. But forgot about it. It looks like I will run mis-matched rims for a while. Well, that's when I get my grubby little hands on it.

And now for some sad news........ With the purchase of the diff, I now don't have enough money or brownie points to go to the Nats. So have a drink for me, you crazy kids.

bugger! what did the diff/subframe setup end up costing you? I imagine much of that cost would be the cost of shipping with that weight!

yeah, it is a bit spendy. 45,000 yen was the buy now. about $680 NZD.

shipping will be in one of Ewans containers.

Yes it is expencive. but it was my birthday (yesterday) present to myself.
