R33 Skyline: How can I tell if it's a turbo...?
Discussion
Guys, I recently viewed a bog standard R33 Skyline GTST. Or so I thought. It didn't seem that fast to be honest, I had an R33 GTS Non Turbo a while back and it seemed about as quick as that.
The car is totally standard with no mods apart from a gigantic exhaust lol. It does have a boost gauge which flickers about and that, and the car was quick. Just not as quick as I'd have hoped.
Is there any tell tale ways to tell if-the engine IS the RB25DET engine rather than just a RB25DE? The only difference I can tell between this engine appearance and my old GTS is that the hose coming off the inlet manifold isn't a rubber hose but instead a larger metal 'hose' that runs across the block.
I can't see a turbo or an intercooler but that doesn't mean to say there isn't one somewhere. Also, are these engines fitted with any form of waste gate / dump valve as I could hear a thing when changing gear. (Possibly because the car is an auto, but so was my old one)
The logbook didn't help at all as it says it's a GTR lol. Which is most definitely is not.
Help and advice appreciated as I don't want to be the mug who pays Turbo money for a non turbo.
Thanks!!!

You should be able to see the T25(?) - it's small but not that small. If the boost gauge moved depending on how hard you pushed on the acceleration pedal then that's a sign the turbo is working. As for a dump valve, it has a recirculated one as standard so it is very quiet.
From memory, it's hidden down on the right side of the engine.
Oh, R33 GTS-T autos are not that fast; it's a smoother delivery of power, though.

Thanks guys. Is it common for people to fit an aftermarket boost gauge (One that's in the dash speedo) to non turbo cars though, sounds like alot of effort for nothing? I'm guessing it is a turbo but just didn't wow me as much as I'd hoped.
Is it possible the car has a faulty turbo? Doubtful as surely the car would perform VERY poorly. Could anything else be the issue?
To be fair though it was quick lol, maybe I just expected to be wowed more.

You said it was an auto - unless you select the gears manually with the gear stick, you won't really notice the turbo as much as it's more about low end torque than turbo kick. Look on YouTube for boost gauges and you will see how they behave on-boost... they jump up almost immediately then edge up a bit slower before dropping sharply between each gear change. Did the gauge do that?
To concur with an earlier post, I was under the impression that, in the lower stages of tune, the turbo or turbos were designed to feed in smoothly, rather than the whooooooosh-bang all or nothing delivery you get with some cars. Having a 6 cylinder engine revving to 8000rpm and the smoother power delivery makes them more responsive, like a NA car. I imagine once you starting tuning them for big power they probably get a steeper torque curve and feel a bit flatter off boost.
Guys, here is the car in question:

To me, it looks like a bog standard GTS and NOT a GTS-T, but did they make boggo looking GTS-T's? I guess so if this IS a Turbo.
What do you lot think?

The chap is positive it IS a turbo, AND it has a boost gauge where one should be, and it does have that large metal pipe running over the block. Every GTS I have seen has a rubber / plastic pipe instead, whether it's the 2.0 or 2.5. (Mine was a 2.5 and had the plastic one)
If you look at any GTS and GTST the only difference I can visually see at a glance IS that pipe, lol
So I'm guessing it is a Turbo... Maybe, the logbook doesn't help either as stated above, it's listed as a bloody GTR, haha

Surely the simplest solution is to look in the engine bay and look at the turbo! Get the guy to point it out to you if not familar. Should feel a big difference from a turbo'd one to NA, chances are the seller is trying to pull a fast one. Move on and view another, doesn't sound like one you want to be buying to me.

Bazza, I had my last Skyline quite a while ago so have probably forgotten how fast it was or wasn't lol.
The chap didn't know much about the car tbh and I seemed to know more about them which says alot!
Where is the exact location of the turbo and the intercooler?
Not sure on the inter cooler although I suspect it will be on the passenger side some where (don't quote me on that). The turbo will be on he right hand side (exhaust side) as you look at the engine bay under the intake pipe work.

To be honest, if there is any doubt what it is, probably best to keep looking than take the risk.
The trouble is Cook is that I would have the exact same problem with ANY GTST. The bloke seems honest. The car is in amazing condition. It's quick. But is it a turbo?
There HAS to be someone who knows why one would have a metal pipe coming off the intake and the other a plastic pipe. Was it pot luck from the factory?
