S14 T28 turbos (let's clear this up once and for all)

[White Comet]

i've been doing some research lately since i plan on picking up an s14 stock t28 turbo, but have not been able to find a conclusive answer. i'm trying to determine if the s14 t28 is a ball bearing turbo or not. some people say all s14 t28s are bb while others say the zenki s14 srs have a journal bearing turbo and only koukis are ball bearing, still others say the euro s14 srs got the journal bearing turbo and jdm ones got the ball bearing turbos. i'm just looking to clear all this confusion up and get a straight answer.

If it's like the s15, only the jap version get ball bearing.

[srdub-t]

my understanding is that all s14 sr t28's are ballbearing and its the pulsar gtiR t28's that are journal bearing

hmm good to know. its pages like this that make me think all s14 t28s are bbhttp://www.drift-connection.com/sr20det-specs.php

There are earlier year s14 mine is a zenki w26 ecu from 1993 . It had the 69-foo bb turbo they also have a 71-foo turbo also which i think is the journal then the 91-foo is the s15 .And the zenki has the valve cover studs and the kouki has the bolts.

so what engine does the 71 foo come on?

im pretty sure some of the s14 sr20's im going to try to find the list i found when my turbo was bad . http://forums.melbccr.com/show...age=3

read through it . and i was wrong its a 75 -foo not a 71 . start at page one.And i just copied this from there site .Heres the part numbers;

Notice how all Aus Spec s14/s14a/s15 are 14411-75F00, indicating that they are all the same turbo, and that the jap spec turbos have different ending serial numbers. Bah i duno.
