Dumb Question Thread!

Is there much performance gain to be had by welding the majority or intercooler pipes together vs heaps of silicone joiners? Obviously the chance of a leak will be much higher and probably the joiners and clamps will add up to more than the welding cost, but surely the size change from the alloy pipe to the silicone is negligible to the flow of it?

Anything that disrupts flow is bad. Would you notice it doubtful. I would weld looks a ****load nicer and hey gains a gain.

Can any one confirm the size of the STi rear swaybar?

Don't wanna get the wrong bushings, are they the same size across the board?

Do you need to deck both sides of head or just the block side?

What do you mean by both sides?

Is he not asking whether to get the head and block skimmed/decked for flatness or just one of them.

Very vague wording.

Or maybe whether to do the block side and the rocker cover side, to which the answer would surely be not to do the rocker cover side. The nature of the rubber seal on the rocker cover eliminates the need for it to be absolutly flat

That's just an excuse to finally buy a set of verniers...

Pfft, don't go getting too fancy on us. Thats my version of a vernier, precision measurements to the nearest 2-3mm

Yeah I should have just said rocker cover side...... Thanks for your answer Andy

Surely you have some in your govt supplied tool kit?

Or not yet?

Half my tools still have my serial no on them haha, constant reminder of a previous life

Which rear rotors should I go for? I hear slotted chew through pads? used for daily driving and weekend hooning. Any opinions appreciated.

De glazing bores. How can you tell they need de glazing? Should this just be done no matter what? Block has done 150,000kms

Will removing the cat or removing the insides cause any CEL's? or any other issues?

Edit - Forgot to say its a 2.5 n/a

For rear I would stick with a stock rotor, especially for road use. Slotted I can't tell the difference (on the front) other than that they chew up pads quicker? (My record is a set of pads in 2 days on a rally).

Ok, yesterday I got my steering boots replaced at the mechanics (girlfriend took it in for me). Was driving to work and noticed the speedo wasn't working. Got to work and had a look and while it was running the needle was on the wrong side of the stop, and when I turned it off it dropped to the middle of the clock in the speedo gauge. I am taking it back at lunch time, but what could have caused this? I am thinking they may have disconnected the cable and reattached it wrong. Can this happen? Just wanting some info so I don't get fobbed off by them saying its nothing they did if it was.

[Marky]

Wut

They shouldn't have been anywhere near the speedo workings to do steering rack boots, that's highly confusing

Re the cat question - no, you'll be fine on your car

[SpeedySub]

I thought maybe the cable was somewhere in the region and they might have knocked it or taken it out to get better access. Would it make a difference that its an auto? It looks like its still working as it goes up to the stop when the car is turned on.

Legacy BP5, how many ft-lb should the drivers seat rail bolts be torqued too?

They're big-ass bolts. Just do them up heaps tight but not too much tight, I don't think a precise torque figure matters on them.

[SpeedySub]

Good thing I posted in the Dumb question section!!! I just realized I said speedo is not working properly. I meant to say rev counter. face Palm!

[SpeedySub]

Just got back from the mechanic. They have no idea and think its just a coincidence. The day before it went in I did notice the trip meter had reset itself back to 0 when I started it, but can't for the life of me remeber if the rev counter was working. Could it be related? or faulty sensor?

[SpeedySub]

Problem fixed. OK so after a little googling I found something similar with another make. They said to rev to about 6k and it should jump around and then go back to normal. Tried it and it worked.
