R34 Gtt Turbo Bolt Onto R33 S2 Rb25det?

[Nanga312]

Hey Guys,

just need some advice as im looking at buying an R34 GTT turbo which will supposedly bolt right onto my R33 RB25det without having to change anything.

looking at buying an op6 Turbo but am unsure as to whether this is off an R34 and if it will bolt straight on?

Ive also been told to get the R34 GTT turbo high flowed.

Any help is greatly appreciated.

Cheers.

Yes. It is almost exactly the same turbo. The internals of the OP6 housing are larger than the 21U housing on your std 25 turbo.

A turbo with an OP6 housing is not necessarily an R34 turbo though. The OP6 was also used on VG30 turbos. I suspect the easiest way to tell the difference would be that VGs probably have an alloy compressor and R34s would have a plastic compressor.

For everything you need to know about highflowing these, look at the stickied Hypergear thread.

/searchable topic.

thanx mate

Actually, excuse my mistake, saying that the HG thread is stickied was wrong. But it's usually always on the first page of the forum anyway.

I will also add unless you're getting it very bloody cheap, go for a hg hiflow. Effectively a brand new turbo for what, $875 or something?

yes, and it's an awesome turbo considering the price tag. Although it doesn't run very well on the standard R33 ecu. I was having issues at 9 psi on the HG 21u highflow

so in other words if you're on the factory ecu stick to the factory r33 turbo. I'm sure the R34 turbo will run okay but it wont be perfect without a tune

thanx guys yeah i plan on getting a Tune as soon i get the R34 turbo high flowed and bolted on along with the cooler etc..

Need aftermarket ecu to tune, but you knew that right?
