R32 Dump Pipe Upgrade

[R32GTS4NZ]

Well i have a r32 gtr engine which was having boost issues, so I pulled the turbos off and there are cracks in the wastegate housing.

While they are off I have come across r34 dump pipes for sale and after reading a few other posts some seem to say they are better than r32 ones.

Are these worthwhile getting? How much better flowing are they than the earlier models? Also do they bolt straight up to everything else?

Advice is greaty appreciated. cheers

If are ever going to change the dumps then you want to do it while you're changing the turbos, so yes do it now. There's a thread on the difference the dumps make, up to you to interpret what's in that thread..... I'm using the xforce splits (with modified o2 sensor mounting) cost me $280 from NZ(ebay) + $60 for the mod, and they seem to work fine. If the R34's are cheaper than that then they're a good option as they will be higher quality.

EDIT: Oh you'll have to either modify the o2 mount (as the 33/34 use different o2 sensors to the 32s), or get 33/34 o2 sensors. o2 sensors are a maintenance item at 40,000kms so you might as well put new ones in either way. The 32 and 33/34 sensors are a electrically different, but some have used them interchangeably with success. I stayed with the 32 sensors as i though it would be lower risk.

Ok thanks for that. i'll probably look at getting the r34 ones then as i have found some relatively cheap. So other than the mount for the oxygen sensor there anre no other modifications? Are they the same shape as the earlier ones and will bolt up to my existing exhaust?

Anybody else have an opinion also? I'd like as many as i can before I actually buy so I know I am doing this right

(not that i don't trust MrStabby:s advice

)

cheers

I haven't used them, so def get another opinion before you buy.

yeah man, people say that r34gtr dump pipes is an awesome upgrade

[R32GTS4NZ]

thanks mrstabby and gfunk I'm leaning towards the r34 dump pipe but would like to know if anyone elsee has experience with using them also? and are they a straight bolt up with only modification being for O2 sensor. Cheers

just a quick question..

would you rather have x-force split dumps or r34 gtr dumps with N1 turbos ? ive come across both and wondering which i should get for future upgrades...

[sickr33]

x-force split dumps are the way to go

fit like a glove and well made
