just run the MP t70
both turbos are only utilizing P-trim turbines and that will be the bottle neck before anything
sure get the t76 and put a larger housing on but you still only have a P-trim in there, heck that is a decent amount smaller than the popular fast spooling f1-68

How much HP you looking to make? My MP70 made 617HP/623TQ on my 4.8 and has pushed my 4700 pound truck to 11.3@121. It's went 7.00 i the 8th on a different day, if I did that when I was at the 1/4 I'd broke 10's. I'd hope you could put a car well into the 10's with a larger engine and in a car.

careful though, 550-600 whp is the general breaking point for stock bottom ends, as im sure you know the 5.3's tend to hold better but pushing it is tricky lol

ok....so I decided I am keeping the T56 (I will probably regret it in the end heh) since I will do more cruising than track time and didnt want to hassle with a conversion.
Hopefully the "lag" isnt noticeable but hey, maybe itd make traction easier :p

I am getting ready to pull my LS1, swap in a 5.3, and install my truck mani turbo kit. I've been collecting parts for it for months, and my original plan was to use a Master Power T70 (.96 a/r) that I have and is brand new. However, I ran across a TC 76 (p trim, .81 a/r) locally that is used (barely), and if I sold my MPT70, would only cost me a couple hundred to "upgrade" to. My concern with the MPT70 is that I'll max it out right away and basically be at my max power from the get go. Is it worth it to use the TC76 instead of the MPT70, or is the difference small enough that if I really wanted more power, I'd need to go with a completely larger turbo (which I don't intend to do)?
the turbonetics F1 series turbine wheels are light years in front of MPT series turbo turbines..
the TC comp covers flow 10 % less than the T series covers. ( 950hp less 10 % = 855 ish HP ).
the .96 a/r turbine housing on the mpt , will be close with .81 F1 series
TC will spool quicker tho. ( smaller .7 a/r cover helps this VS .55 mpt)
if the TC turbo has the HP series new comp wheel , this will help greatly...
F1-65 = new version of P trim... way better flow
data recieved from back to back tests, with T series and TC

Crashly,
would you say that the T vs TC would help by about 10% at what level? I assume there would have to be a flow level that the TC starts to choke up?
Also, can you elaborate on the new HP compressor wheels? How do I know if my turbo has one ? Is it just the most recently used wheel, or does it have to be specified upon order?
Thanks!@

low down in boost levels, you will not see much at all, if any.
Thats why the TC stuff goes really good, and exerllent value for money.
looking at the compressor wheels, the exducer dia, the blades sweep back worlds slightly... the tip hieght etc is also different.
the part number will show what wheels they are.
same with F1 series turbines VS older p trim , Q trim etc..
i dont have any pictures of older stuff here on my laptop.
I believe DR Turbo can up grade the compressor / turbine wheels .

only at the max levels, when ur really pushing it..

How much horsepower do you want?
I am surprised that no one has asked this yet....
If its just 10's that you are after the MP70 will most definitely put you there, the 76 will too. But if you want 700hp or more then the MP70 is out of the picture.
I am sure that this next statement will start a **** storm but.......
IMHO the T70 will give you quicker spool up for the street, would feel really fun stoplight to stoplight, and would accomplish your ET goal. I feel that there would be less spool up drama on the line too.
my 2 cents
Of course a bigger turbo will "make more power" most of the time and if you want room to grow later then the 76 is a wise choice. There are many things to consider here with this decision, budget comes to mind as well.
