Tech Spam thread - because 1/4" BSP gets 5 hand spans to the jiggawatt

Very little redeeming features then.

Slow, thirsty, and no fruit?

Yep, all of the gas hogging and no overdrive on the auto. It wasn't terrible as a family wagon though.

Anyone know if these dots speak tensile?

(From my split rims).

I can only find refs like these

Thanks brains

J160 gearbox tutuing 

Has anyone done the mod with the remote shifter to move it forward a bit?

@Roman? 

[HighLUX]

And is the gearbox output spline the same as a W series gearbag?

[Roman]

Yep same as w box.

There are two positions on the factory box for the shifter, easy to flip it to use the front set of holes.

Otherwise sq engineering etc sell kits tbat move it way forward.

@kpr and @_Matt projec threads have them doing this mod

Just got the gearbox and being a 1G box it already has the shifter in the forward position 

Guess I just offer it up to the tunnel now and see how far back it is compared to the hole for the gear stick

I hear the sq one doesn't feel amazing. as it turns it into a short shifter as well.

I found if you run slightly too much ignition advance it makes the engine carbon up a bit , knock back the timing and it burns really clean.

Anyone got experience in building engines and balancing rod weights?

Due to production changes the new rod for the Alto started at 9g heavier than the old ones. Using my balance jig I have removed about 4g off the big end which is within about 1.2g of the lightest rod, the problem is now that I need to take another 5g off the little end of the rod. 

There's no material to remove there, but one of the production changes was to add raised bosses in the middle of the rod with the text on it instead of being flat. 

Is it safe for me to take a die grinder to that raised area in the middle and try to shave it down flat (or as close as needed to get the weight within spec)?

I want the rods within a gram or two of each other since the engine will regularly see about 9000rpm. 

[kpr]

yep, thats where i would be taking it off

I suppose the other question is, is it worth pissing around or should i just send it as it is now? The difference is something like 1.2% of the total weight of a rod...

I think it is worth the pissing around

Yeah 5g is worth a zing.    if spinning it up to 9k

I did it, took all the casting lines off the edges and zipped down the text a bit. Its now the same as rod 2, and 1.74g heavier than rod 1. Good enough.
