I was talking to a close friend of mine, who is an audi guy, and one of the few people I trust with any of my cars.. The APR tune i have sucks ***** it was never finished and im going to be installing scat rods and some other upgrads to the motor. Well we got into a discussion on ball bearing turbos and journal bearing turbos and we talked about price reliabilty and how easy and cost effective they were to have rebuit. If I went to a bigger turbo i would buy a 30r buy they cost around 1500 or so, and it like 800 to have it rebuilt. I can go with a T3/t4 hybrid gain a bit of lag still make serious power I think he said a t3/ 60-1 would be a comperable turbo to the 30r, which i can pick up new for what a new CHRA install for my gt28rs will cost, and its only 200 bucks to rebuild. I dont know much about turbo or what to get but are there really any huge benifits to a ball bearing turbo. seams to me if i can get the right hybride get a custom tune i would be far better off then I am with the gt28rs and the crapy unfinished apr tune..

 

everybody has thier own way to make the best power possible...

if his way is legit, then go with it...

 

the main advantage with a ball bearing turbo is spool up time. because there's so much less friction on the turbo shaft, you build boost a lot quicker than you would with the equivalent journal bearing turbo.

 

get a GT series. you would be hating life if you went from a GT28rs to a t3/t4 the size of a 30r. way too much lagg

 

from what i have been reading its only another 300-500rpm's that not all that much..

 

when yoru racing it will make a difference.

 

I dont know how 300rpm can make that huge of a difference

 

was thinking on something like this turbo right hear..

ya thats a little bit larger then what i had on my car on stock internals. you wont be able to run as much boost as i did unless you build the motor or blow yours up

 

oh, well thats the thing the reason im thinking about a larger turbo is because im puting scat rods in, with a bottom end refresh, bearings rings, ect and fixing my vavle seal problem. also looking at this turbo for less lag http://cheapturbo.stores.yahoo.net/gat350trw63a.html.. my goal is around 340-380whp and i have a water meth system im going to install as well
