Dumb Question Thread!

Mint. Saves trying to find a v7 one.

Righto chaps and chappettes, I have searched but cannot find the thread or post about de-catting Rev-C GTB Legacy's, I know its on here somewhere!!

Anyway, while I have the exhaust in bits, I was thinking of removing one or both cats.

Just can't remember if it causes any issues with over-boosting or under fueling or if it needs a tune or boost controller etc etc.

What say you savages?

I have been "told" that you shouldn't decat the primary, something about free boosting?? Don't quote me though amigo, it's not something I've done to mine and I'm wanting aftermarket downpipes anyway

note: centre cat was removed when I bought car but thinking I want 3in straight through anyway

Just need an aftermarket boost controller. Or port the primary wastegate and play around with different sized restrictor pills in the OEM boost lines.

[B4 I was 250T]

If you port the primary waste gate do you wanna do mine too?

[Rosssub]

Yeah man, send a spare exhaust housing over.

[B4 I was 250T]

Lol I was meaning for Percy if he does his but if you wanna do it Ross then let me know a price

I could do!

My cunning plan was to get a newer/ rebuilt primary and port that, would save time over taking my old 230+k turbo out, porting it, then having it lunch itself because of too much lolzy boostage, then having to find another turbo etc etc.

So me needs to acquire a boost controller or pills before de-catting the primary, but the second cat can go to the great cat heaven/ scrap metal no worries!

They do apparently - I haven't tested to check, but been told by (Subirex) that they do - he's got brembo's on his bp too

I'd be surprised if they actually don't - 315mm stock set-up is not tiny at all. Should try to be 100% sure though, don'r want to stuck in the middle of nowhere one day

Had a similar issue with a spare not fitting over 4 pots. Had to swap a tyre off the rear to the front, then spare went on the rear.

Its the width of caliper not size of rotor thats the issue isnt it? My setup fits under a 16" sti rim. 315x30mm rotor sumi 4 pot.

I have restrictor pills sitting around I believe. I think they're 0.8mm

Coolies, cheers dude.

Also thanks Ross, I thought what you said was the case, just wanted to make sure before doing something silly and causing explosions!

Yep that's the plan.

It's a bit about concavity too isn't it? The larger the rotor the more the caliper pushed towards the concave part of the rim. Don't think rear Brembo is that much larger/wider than front BLE stock (or your 4pots), same size rotor.

Width of caliper/concavity same effect.

Spare should always go on the rear regardless.

+1 especially if it is a "spacesaver"

[patrickc22]

My applied model code is bh5c5ct so this makes my bh5 a rev c?

That's an excellent point (and obvious now I think about it).

Because this thread says the mine is a bh5c5ct ワゴン GT-B E-tune http://clubsub.org.nz/forum/showthread.php?1975-JDM-Legacy-applied-model-codes

but mine was inported into nz new in 2000

so I'm a bit confused

What are you confused about?

[wrx_lou]

I'm thinking the fact that its a My01.

Would be produced at the end of 2000.

Its like how you can have a 1998 or 1999 V5 and a 1999 or 2000 V6.

Or a 2000 V7 etc.

Subaru MY starts in May isn't it? Rev.D started in May 2001.

Its definitely around the middle of the year, when I google my chassis code it came up as June 1998, and mine is a Rev A BH9.
