What Turbo Is This?

[|PRESA|]

I was lead to beleive this was a VG30 turbo, I had plans to use the turbine housing to ad to my hi-flow of my stock RB25 turbo.

I didn't know exactly what the VG30 was supposed to look like but if someones selling an apple you'd think it would actually be an apple, right?

I thought the VG30 was supposed to have a larger turbine housing so I sent photos to GCG in Sydney for a discription on what I had just bought.

They came back saying it's an SR20/CA18 Garrett T25 turbo and asked (quote) "Who the hell told you thats a VG30?"

So my question is - Is it a VG30 or a Garrett T25?

If GCG (with their experience in turbochargers) are wrong about this one (as one person thinks) and it is in fact a VG30 then I will personally give the turbo back to the seller (he can keep my money as the turbo is useless to me) and he will have a true honest apology!

Thanks..

hey PRESA .. im going to my engine builders tomorrow to pick my RB25 head .. i'll check the SR20 thats sitting at the workshop...

also have some stock CA18 ones sitting at a mates that i can check too..

would be easier if you could give us the numbers on the plate between the housings would make it easier!!

Ok Sweet.. the turbo is at work so I'll post up the numbers tomorrow.

It's pretty filthy of oil and stuff but when I had to give it a whipe back I noticed the GARRETT logo on it and then I could just barely see A/R .45 or .48. Thats when I thought hang on - I'll ask GCG before I send this up to them asking to hi-flow this for my RB25.

I was told by discopotato awhile back that RB20/RB25/VG30 are all nissan turbos manufactured by Hitachi and not to confuse them with anything to Garrett. The only vague similarity are the T3 flanges - which this turb doesn't have.

** I can post up photos of the flange if necessary.

do a search on vg30 by user "bass junky" in forced induction. him and cubes had pics i think of a vg30 rear housing

[paulr33]

the first one looks like a bnr32 twin and the second one looks like an r32 stocker

[|PRESA|]

The seller said it was off an 300zx 1989 model - I'm not doubting it is off a 300zx but is it a VG30?

[|PRESA|]

I just came across this on google after searching "VG30 turbo" under images..

[paulr33]

yeah pete (bass junky) and a few others were out to compare vg30 rear to gt25 rear and try the gcg custom hiflow changeover

[paulr33]

if i look for a hiflow / aftermarket option im gonna be speaking to racespec see what they can do as far as a garret equiv of the hks gt-rs im pretty sure they can do a gt-rs spec for cheaper or even a gt-rs front wheel and compressor and vg30 rear supplied as well

if i do consider it, which will be never

[|PRESA|]

Thats exactly what I was going to do, after speaking to SK he told me some good power can be found with a VG30 turbine housing on the standard RB25.

[nuR.spec]

just make sure you differentiate correctly between the VG30DET turbo and the VG30DETT turbo..

[Chef_32]

yeah, its probably from a vg30dett which have smaller stock turbo's than the vg30det from the r31 which are considered a good upgrade.

OK I had a look..

It has a Garrett logo on the top.

Underneath it says -

SK 16395

14411-40P16

here you go:

I quoted the number 14411-40P16

Don't believe me? Here's another

I guess your "boys" at GCG need to reconsider there occupation and maybe do the logical thing and go off the serial numbers

Apology?

It's not a VG30DET turbo.....they don't use a 2-bolt flange on the compressor inlet.

[nuR.spec]

it was never stated as being a VG30DET turbo, it clearly stated that it was off a VG30DETT..

Actually the OP has it as 'VG30' and it is clear that some don't understand that there is quite a difference between a VG30DET turbo and a VG30DETT turbo. It is also clear from the first post that he was after a VG30DET turbo, but has actually bought a VG30DETT turbo.
