I was just wondering if the TTi 60-1 Turbo(i believe the street kit) would be too much for the stock 4L60E and if i would need a forged shortblock or anything like that? I'm really wanting to do a turbo.. The Race kit would give me too much power for a daily driver.. I'm just looking to Get the Turbo, possible built trans, Boost gauges, Fuel pump, ect.. But i don't want to have to touch the Pistons and rest of the engine to make it streetable.. Does anyone have this kit without buying a shortblock or changing heads or postons? Or possibly on a 4L60E with a shift kit, tranny cooler, and high stall converter? I already have the F11 cam 228/230 .575/.595 114+4.. Is that cam too big for a turbo set up? Sorry if i sou nd very uneducated about turbo set ups, but i just started looking into it! Any help is appreciated!

Cost of TTi Race kit is just too much..

Skip the T-60 and just get the T-76.

yea with the T-76 i'll need new pistons and everything.. and i don't really feel like buying a forged shortblock or anything like that.. Will i need to do this with the T-60?

Take a look at the horsepower rating rather than just talking in terms of turbo sizes. A T60 should be good for about 500 hp. It will produce plenty of boost for a stock short block. It is very, very, very important not to fly blind after a turbo install and to get a good tune before stepping on the Go Pedal. Tune, log, tune, log - make sure it's safe, because you can screw things up in a matter of seconds.

A T76 is going to hit really hard, and would be a great option with forged internals and lower compression. Get some additional opinions. Splitting the difference with a GT-series 67 would hit hard at 5-8psi (intercooled or alky injected on 8), would spool well, and be a good stepping point if/when you break something and have to rebuild.

Don't sweat it...the turbo is cheap compared to R&R, parts, and a rebuild on an LS1.

id get something a little bigger then a T60, but it all depends on your HP/ET goals.
you can do a T76 with stock internals, has been done many times before.

I have the T76 kit and I did build my tranny and went to a forged short block after smoking two pistons on a safe tune. BUT I was running 10# of boost and also overboosted the motor once by accident. You dont want to limit yourself, trust me you will want more power later and at that point you will be buying the same parts twice like a bigger turbo or downpipe ect... My advice based upon my experience is get the T76 kit with the Racegate wastegate and the 3in downpipe with the 2.5 inch under the engine crossover. I got the ceramic coating on all my plumbing for $500 and now I realize that I could have spent that money better on system upgrades. Remember you can always just run 6# of boost for awhile till you have the money for the tranny and a stronger shortblock. Dont worry about the tune if you are going to Livernois, Greg is a good tuner.

I've had both the T-60 and T-76 and there is reason not to buy the kit with anything other than the 76. Both have a really quick spool, the only difference will be that you will easily max out the T-60 on that kit. It would be really tough to get above 450rwhp with this kit and a T-60. That's just what I have seen on my car.

Does anyone know the highest rwhp anyone has got from the T-60? I know MYTURBOT/A pushed his really hard and I think it maxed at 430rwhp, and that was with a 6 speed.

Just go with the T-76 and run it on a low boost setting (5-6 on pump maybe 8-9 on race gas) and you will be alright.

Later,

The 60-1 is way too small for ya

awesome guys! great information and advice.. Alright then i guess the only thing i was afraid of was ruining my engine.. I guess i don't have to push the Turbo to 10 psi+ and i can just stick with around 6 psi..

What kind of #'s or 1/4 mile times has anyone seen with running around 6 psi on pump gas?

Also would i definately need to get a built 4L60E even while running 6 psi on the T-76?

Thanks a lot guys i appreciate all the help and advice! I'll be saving for the T-76!!

i ran 116mph traps with 5psi on stock engine and a T76, i should have been boosting more then. on 10psi i ran 126mph traps

what kind of times were you running on the stock engine smokinhawk? You have any bolt on's? you think you could of pushed the stock engine harder than 5psi too? let me know! Thanks for the reply

The 60-1 is a little to small for our motors. You would be better fitted with a T76.

thats pretty fast for a T-60.. what else was done to your car to get the 121 trap speed mightymouse? bolt on's? Cam? thanks for the info

it had 3.73's in the 10 bolt, a random tech cat back, no cat and a 1.99 60'

Definitely go with a T76 as everyone is saying.. you will thank us later.... even the little T66 I had was too little.
Knock on wood, my engine seems to be just fine.. stock everything minus the valvesprings/cam w/74,000 on the clock. I was just getting motivated again to get going again on a larger turbo/set-up... now you guys have me worried.

my 60' times sucked (2.2's), i was a noob then and didnt get but at 13.1

definatly could have pushed the stock engine further, but i couldnt get the power i had down the track then. i only made 384/420 with 5psi on the T76 you really need to boost it over 8psi to get it in its efficency range. my car was stock other then that a clutch and injectors, pump, ls1 intake too.

and get the T76 forsure.

smokinhawk... You ran the 13.1 at 5psi on the T-76? or was that the 60-1? Do you think i could run 6-8 psi safetly on stock internals and still make good power? Will i be able to run the turbo set up at all without a built tranny(A4)? I see in your sig you are running it at 10 psi on 94 octane gas.. You have stock internals still or no? what about a stock trans? I'm pushing close to 400 RWHP as of now without any turbo.. what do you think? Thanks

Back on the "building your 4L60E" question....my automatic lasted a whole 2 weeks after getting my car back together with JUST a T-60. I'm starting the rebuild on Monday.

If you don't have a built auto, start saving the money now and planning....
