unless you are after more than 600HP, and therefore require more than 20psi worth of air flow a T04 will out perform a T78 or similar spec turbo.

Look at ADAM, ABLE both use to4 based turbo's .... I think their results are better.
In Australia, ALL the 8 and 9 second cars use TO4's, it is down to personal preferance I suppose.

Unless you are wanting over 600hp at the flywheel and therefore require psi to be in the mid to high 20's then a T04 based turbo will give you better results.

look at the compressor maps the t-66 is a monster.
ON the map you will be at about 35 on the bottem and depending on intercooler about 1.8-2.2 on the left anything bigger than a t-66 you mite start surgging. get ball bearing extrudehone it, and jet coat it put your name on it. Save the greddy turbos for guys that have alot of extra cash me I will save for other stuff. Don't get me wrong I love greddy I have the following greddy stuff: type r bov, profec a, turbo timer blue, there great but turbonetics is cheep and kicks some boost.

I Agree... US has the worst case of name brand syndrome... The key for Rotary's is in the Exhaust housing... This is where the power is made!!! So a t04 with a nice big exhaust housing will be plently of power...More then enough for a street car... A Turbonetics T66 would be an excellent race car setup but i wouldn't go any bigger on the comp... All that's going do is make more lag. As for the greddy t78 & t88 there just a big waste of money... Hey if you want to throw your money away let me know and i will be more then glad to take it..

I agree, unless you are building a track car who cares what Ari, Adam, Able or Ray are using. Their cars are built for track straight line performance. Also they don't worry about lag since they have otherways to compensate for it.
I daily drive my T04S and i have no problems with it...power is good and responce is good enough. At one time i was debating getting the T51R but like the T88 I don't think that it is as practical for street use as a simple T04 set up. At the most i might switch to HKS' new T04R kit.

I am VERY confused.
Is the Turbonetics 60-1 the same as the T66?
And could somebody maybe direct me to a webpage that explains compressor blade angles, trim angles, etc. and if it's not a ball-bearing turbo, what else could it be?

the 60-1 is a smaller compressor than the T66, it flows less air.
for the optimum set up you want the smallest compressor that will flow the air for the HP you require, that way the sheer size of the compressor isn't hindering spool up anymore than it needs to

it doesn't matter what people think, if your comfortable with it why care what people think about your set-up? all set-ups have their upside and downside it all depends on you on what you want to do as far as everyday driving or different types of track uses such as autocrossing or drag racing. You can do what I'm about to do and build 2 different set-ups one for autocrossing and drag racing.
