identify turbo

[turbodaily]

anybody know where abouts the serial no. usually is on the gt turbo's? is it a plack or just punched in somewhere? guessing thats the only way to identify exactly what model my turbo is, gt28rs or a gt2871..?

exactly same as below with 4" inlet

seems to hit full boost around 3700rpm. its major sarcasm's old turbo, he seemed to think it was a gt28rs but im not 100% convinced. mainly due to spool up time, thought a 28rs wouldnt be as laggy as 3.7k rpm?

probably a 2871 it was ordered from jgy by the owner before major as far as i remember as i bought loads of bits off them same time as him a few years back now

Possible to measure the compressor wheel size from the housing ?
from there you roughly know the turbo size and spec

looks like the GT28rs to me.

Take a look HERE at the JGY site

hard to tell, the only difference between the 2 is the comp wheel size. the gt2871 should be 71mm according to garret. so if i can get something in there to measure it i might get a rough idea.. will give it a go

out of interest when should the gt28rs come on full boost?? im hitting boost just under 4k.

I have a GT2871r and the serial number is on a small plate between compressor housing and turbine. Think the compressor housing can vary depending on what you order.
Some turbo suppliers fit the OE Pulsar compressor housing for the GTiR...
The P/N on my 2871r is 743347-0002

i had a look earlier and couldnt see any plack, unless its on the backside where i cant see it.. mine is the same as the one above ie. not original style comp housing.

With my turbo fitted, I can't see the plack as it's on the back side facing the engine block between oil and water feed.

the old owner was prkwan or something like that

 

[turbodaily]

i measured the size of the inlet earlier (marked below) which was just over 48mm if that tells you anything?
