How to tell if 33 or 34 N1 turbo?

[180bfj20det]

Hey, Im installing n1 turbos on my bros gtr. How can we tell if they are 33 or 34? There's a tag on it which some numbers and stuff, can this you help?

Any website with good info on the N1 turbos?

[GTR R32]

Can you post a photo?

Here's a few ways to tell the difference:

R34N1's are ball bearing (see if it spins easy)

R34N1's have 9 blades on the turbine compared to 11 for the R33

R34N1's compressor housing does NOT have the A/R marked on it

R34N1's have a divider between the wastegate and turbine

You should be able to work it out from that.

Cheers,

Gary.

Gees, thanks for the info. Guess they're not 34s cause A/R is marked and plus there is no divider for wastegate gases...but they sure as hell spin easily. They're actualy meant toi be NISMO N1s. Could these be BB?

Only BNR34 N1s are BB

There is a small plate which has the serial number, find this and you'll find your answer

[Guest Mashrock]

Just a note on this i just recently picked up two brand new R34 N1 turbos for my GTR so new they had not even been removed from the nissan box and wrapping.

the only cost me $3000 for the two, and thats to my door. i know a guy who sells them for about $2800 for the pair brand new :bananaman

What's the serial number meant to be for the 33 and 34?

My bro got them from Banzai motorsports for ~$2500 I think (ANTS?).

Cams... what size do you recommend? Its true that the GTR has piss small cams standard (unlike the FJ20). Personally, I think a GT3540 plus a set of 272s would be nice!

[Ants]

Dude, turbs cost me $1,900 from Banzai.

Yes, I agree GT3540 would be nice. Pls buy me one.

Seb, I also got a new exhaust manifold gasket today from Hi Octane Racing.

Now filing for bankruptcy.

Are these R34 N1s ?? ballbearing steel wheel good for 320hp each ??

[OohArrGTR]

anyone??

[itbmils]

OohArrGtr

check the serial number (from above post) - if they are R34s - then they should be good for 600+ hp on your GTR.

I have just had a pair fitted - waiting to run in the new bottom end.

BTW - nismo.com.au list them as 320hp and are selling the pair for $4K + I think

[GTR R32]

They don't look like R34's as they don't have the divider between the turbine and wastegate. They look like R32 Nismo's. Still rated at 320 HP but not ball bearing.

[OohArrGTR]

arr there getting put on right now at the shop will head over at lunch and try to get serial number before they go on!!! .. anyone confirm there 32s??
