I have read conflicting info from all over the internet.

Ok so far as best I can tell the only down side to the GT35/40 is the cost invoved.

But its BB so it provides a better low end than the t04r

I understand the the t04r is very inexpensive to rebuild. Correct or no?

And answer me this, generally speaking, All things being equal what kind of life expectancy does each turbo have?



If these questions are to easy for you then forgive me.

Im a single turbo newby

BTW Does anyone have a good pic of a to4R ?

I wanted to see the two next to each other.

The simple fact that the gt35/40 is dual bb and the size configuration makes it more streetable. Still delivers good power to a point. Don't think anyone has dynoed it at 20psi yet though. Ball bearings are just about always more expensive to rebuilt, so the T04R would be the cheaper turbo. Kinda hard to tell how long they will last, but BB will take more abuse and probably last longer.

if you are talking about the HKS brand label To4R its pretty expensive too. I'd prefer the 35/40 for the way the power is delivered. The to4r is sort of a violent all at once power delivery that i don't like because its very difficult to manipulate the way the power comes on using the gas pedal. I don't know how the GT3540 fairs in this respect, but it seems that it starts spooling early and has a sort of gradual (controllable) delivery of power by the looks of the dyno sheets.

I bought my T04-R used.. been useing it for over 2 years now.. it could probably use a rebuild here soon. Total cost to rebuild is around $100 and its somethig that you can do. But its a good turbo, would strongly recomend it.



I had a pic of it on my computer.. but it broke right now..and I have another on the nazi forum.. but guess what.. its screwed up right now also. I'll post a pic of mine as soon as I can.

If I was to choose(money not involved) I'd pick the GT3540. If money was involved, I'd pick the T-04R or turbonetics T-66.



I know...I'm running an HKS T-45S...why aren't I running either of the two...simple...MONEY. https://www.nopistons.com/forums/pub...IR#>/blink.png

To4-R, cause it has an R, like type R, or pirate type arRRRRR.

I personaly would like to upgrade to the t04r but the 35\40 is also very tempting https://www.nopistons.com/forums/pub...1047683358.gif either turbo would be fine for the street, but it would all come down to the size of your wallet

The to4r is ball baring also.

It is? Hmmm I wonder what turbo i'm thinkin of then, i'm confused. https://www.nopistons.com/forums/pub...IR#>/smile.png
