Upgrading R33 S1 Turbo To R34 Gtt Turbo

[monkeykplunk]

As the topic says, I've bought an R34 GTt Stock turbo, and I just wanted to know if anyone knows if the water lines and everything should bolt up directly when we do the swap?

I'm trying to find out now, so I know if I have to outlay some more money for braided lines or something.

I'd rather not spend the extra money as I don't have a whole lot to spare.

ya i swapped my rb20det turbo to a r34 gtt neo turbo and everything lined up.

so you will have no problems esepcially if you already got a rb25det stock turbo. basically the same.

[SiR_RB]

is the 34 gt-t turbo the same as the r33 series 2?

yep should be a direct fit

[NYTSKY]

R34 turbo has a larger rear housing.

[MANWHORE]

not all r34 turbos have the larger rear housing. Straight fit though.

But is it actually an upgrade item tho?

I dont see many/or any ppl upgrading to a 34 turbo if they already got a 33 turbo on there car.

Whats the gains? much? any at all?

Not sure how true this is but I've always thought that part of the 20kw increase with the R34 was due to the bigger housing on the turbo. The other major change was improved VVT.

For this application, the R34 turbo should give some gains to an R33 s1. The r33 s2 has the same ceramic turbo as the r34 but the r34 also has a plastic (nylon) compressor wheel, which I dont think the the r33 has. This makes the R34 turbo slightly more lightweight and therefore should give better response in theory.

All the best with it

Thanks guys.

I'm only upgrading because I have a suspicion that my stocker is possibly on its way out.

And I got the turbo at a really good price.

Series 2 R33 turbo's have the nylon compressor wheel as well.

let us know how it goes performance wise

dont spose you want to get before and after dyno runs for us?

[MANWHORE]

In regards to whether it is a worthwhile performance upgrade if you have a working r33 turbo - not really. Not really worth the money for minimal minimal gain.

If you had a busted turbo then sure, why not go for an r34 one since it's newer.

For a 34 turbo, you're looking at paying around 450 (cheaper if you're lucky). save that money towards an aftermarket turbo instead of going for 5-10 kw (if even). I've ran a 34 turbo before, and difference was minimal.

[monkeykplunk]

^^ Too true....

The only thing you really need to remember when going aftermarket, is that turbo is never the only thing you can or need to upgrade.

And then theres that whole modding bug thing that you'll never get away from

[MANWHORE]

yeah, definitely monkey. that's spot on the money in regards to ecu, injectors, afm, cluch, tyres, suspensions etc to take advantage of the turbo.

I think I might have been a bit unclear. what I was saying was, for someone with a working r34 turbo, it's not really worth the 'upgrade'. migth as well save up for the a/m turbo. but of course, they need the other parts, as you said above.

but for someone with a busted turbo, they can either go cheap and get a 2nd hand one, where they might as well get a newer r33 one or r34 one (less ks). or, if they want more power, better to go a/m - refer to mods needed above
