R34 Trust Extension Dump Pipes On R32gtr?

[gtr fan]

Hi all

Can I use r34 trust extension dump pipes on r32gtr? Is it just a matter of using r33 oxygen sensors?

only diff is the 02 bungs. (from memory it comes with adapters anyhoo)

I think you will find even if you use the bungs that the R32 o2 sensors wont work as they will be two short to actually end up in the exhaust flow

So use r33 sensors?

But then these have to be bent to clear some other pipework or cabling don't they?

Maybe I should just go the Tomei's. I already have a good aftermarket front pipe but I don't the its as wide as the tomei outlet.

Go tomei, the trust ones are a pita, i swapped mine out about a year or so ago..

my new front pipe wasnt quiet as big as the tomei outlet either but a die grinder made it a little better for flow.

Make sure you got the gtr one and not the vspec ones. They should all fit perfectly (maybe o2 will need some work) across all 3 models but the 34vspec has extra o2. No biggy, just need to find a bolt or bung to seal it up.

Why bother with the O2 sensor?

The RB26 is not a fuel efficient engine and having the O2 won't help much.

I changed my Mines dump and front pipe, which is similar to the Tomei dump, to the Greddy and gained a few hundreds rpm of boost response.

BTW does your Greddy front pipe have a flex pipe? If it doesn't, it would be best to get one installed.

ORIGINAL Trust pipes come with adaptors, so it doesnt matter what O2.

be careful of copies though. There are a solid number of cheap knockoff's floating around for a while whose flanges etc were all uneven, different sizes etc.

Thanks everyone, I have spotted a genuine set. Just know there are mixed opinions about these pipes.

The only reason I am considering is because the price is not much more than tomei dumps.

I think they are fine.

Only reason i took mine off was ride height issues.

RB26's sit heaps lower in a HR31 shell, so i was about 80mm with them on. Otherwise they'd still be on there

they are the best flowing kit on the market.

I actually think there was a set going cheap at autobarn narre warren when i was down there last, nearly bought it as a spare.

Just be mindful about the O2 sensor types, R32 GTRs use a Titania based sensor, while 33's and 34s use a Zirconia based sensor, you can't use a Zirconia based sensor on the R32 GTR ecu (well you can, but it won't work as well).

+1 for the trust pipes...

I have them, I love them... fitt perfectly.
