I don't think anyone on here is recommending a 35R?? I think with the 40R you will find it is not worth the price or headache. Wheels are a serious pain to get for that turbo should it be needed. We saw only marginal gains over a 35R with it, as have other very well known local "piston" shops. You will get much better reponse and a higher eff. as well as being able to run higher P/r's out of the 500R than will the 40R there is a reason I don't offer 40R kits anymore 
Not knocking the turbo. Just Garrett took forever getting them to market, and it has no advantages over the 500R. The 500R has a broader taller comp map. That is about as best a 40R/500R comparison I can give. Again I think you will be fine in Rays hands he is very capable. You should go down there and spend some time and talk to him.

matt, if you're going to have a low boost setting, then i think the 500R turbo is going to suit your need.

IMO: Get the biggest turbo you can afford.
Why?? Because, why give yourself a glass ceiling??
Why have a turbo that will max out at 500hp??
Get a turbo that can reach *ahem ahem* 685Rwhp.
then Tune it down to say 500hp.. So turbo isn't even working hard.
Last thing you want, is to buy another turbo in 2-3 years.
Because you want more power.. which isn't out the question.
Believe me, Big power is very addictive.
Lag this and lag that. IMO, is over blown.
When you go single, and have all the suporting mods
Traction will be limited to begin with. So on the other hand
the Lag is good because it helps with traction from the dig,
before it hits boost and Rockets(literally) down the road. Even then
you may still go sideways in 3rd and 4th.
Even with Lag, Tach your FD up to 4-5K and go WOT,
you'll think to yourself.. "WHAT LAG" its rather trivial.
Plus you can puttputt around town and not even get on Boost,
which is less wear and tear on your car. Save gas also.
But when in need, just drop the hammer(throttle).
BTW: you may want to budget for a Puck Clutch also.
If Ray at PFS is going to charge you 5K for a rebuild and same price for a
reman and rebuild. I would just have him pull your motor out. You keep it
for spare and Have him build the reman/rebuilt in your car. Or vice versa.
Can't go wrong having a spare Motor..
I got T78 FD..

yeah thats a good post slingshot and i tend to agree for the most part. The only thing is i want a car thats fun to drive though too...zipping thru traffic etc. Most the time when driving my car its nice just to feel the primary turbo alone.just to feel the pep of the car...ya know what i mean. I am nervous that wiht a t-78 the power would be like a light switch...on off. But having said that i dont want a set up that is gonna make me want more in 2 yrs or when my buddy slaps a cam in his already 500rwhp z06. i am embarrassed to say that myself and my two best friends have one nasty rivarly going on. its terible...and we are all 30plus yrs old. go figure. actually alot of the reason for this upgrade is b.c of this.
the deciding factor is gonna be 2 part....1) once i see more 500r dyno sheets (which will be very soon) and 2) when showoff takes me for a ride in his t-78 car. Yesterday i was leanign towards the t-78 but today i am leaning to the 500r.
The part about my engine costs under the two different scenarios still baffles me.

Size doesn't always matter. And more power sooner is going to be quicker all other things being equal. At 75lbs/min a GT4294 will be roughly 73% eff. The physically much smaller 500R is also 73% eff. Boost is irrelavant airlfow is what your looking for and at those numbers you pretty much the same. 75lbs/min@73% That said the 94 should be good for up to 34lbs where as the 500R is good up to 30. So there is a slight advantage up in the higher boost levels. (ie P/r of 3 or higher.) Now if you step up to the 4202 well then you jump up to the better efficiency roughly 76%@75lbs/min versus 73% and you can run upwards of 89lbs/min. and still be pretty close to 73/74% eff. That is where the difference is. -S-

maybe this is off topic, how about T-88 turbos?
if you want to maximise the HP, you might as well go with T-88 right, i was readong something like this few days ago where you can get around 850 HP with the proper tuning.
