GTX3076R, GTX3576R, GTX3582R

I'm trying to hit 450 AWHP
I've done my research, but I still can't decide
I'm tracking the car every now and then,
I don't wanna build my motor, it's a complete bolt on, with an ETS manifold and downpipe
I'm buying this kit from ATP

Thanks for the help

You should look into a stock replacement turbo for 450whp. it's not that difficult to achieve and the spool with be closer to stock. Look into Forced Performance, CBRD, and MAP for a badass, quick spooling, stock frame turbo upgrade.

But to answer your question go with the GTX3076R. quicker spool than the other two and you'll hit 450whp with proper tuning and supporting mods on pump gas or E85

GTX3076 for your power goals. Bulletproof reliability, good spool, large power potential. The 3576/3582 are 600whp turbos and the slightly additional lag is not worth it if you never plan to push the power that high.

What the other guys have said. If 450whp is your final goal. Either a stock frame turbo or the 3076 would be good options.

Personally, I'm going with the 3582 because I plan on building the rest of the motor down the road.

I'm going with a 3582 as well. Don't want to do it twice.

I would vote stock frame, but short of that the 3076.

TDV

I asked my tuner and he said I'll be pushing the 3076 to the limit if I want 450 and I might need cams, but the 3576 is the best for what I'm shooting for

Are you trying to hit 450whp on pump gas?!

TDV

Yup, no e85 or race gas, I'm getting fic 1100 injectors and walbro pump, I already have an ets 4" intercooler with pipes.

IRPerformance

Go for it. People are afraid of larger turbos because they think they will be laggy. Nothing is going to spool as fast as the stock sized turbo. At the same time, the stock turbo has no punch. The turbine housing becomes a huge restriction at higher power levels and it takes more boost to make the same power that a larger turbo would be making at a lower boost level. More boost = more stress. Every evo with a stock frame turbo I've driven tends to lose steam past 6000 rpm. A larger turbo will pull hard to redline. If you get a ride in a properly set up car you'll never go back. Have you considered Deatschwerks for injectors? They drop right in.

TDV

Then I'm getting the 3576 with a 4" intake,
I have considered it but I heard that FIC is way better
And they have the plug and play option

450whp on pump gas = GTX3576R with the 0.94 A/R housing. If running E85, a GTX3071 would do 500whp maxed out. But pump gas requires the larger turbine wheel.

TDV

about the injectors, dont go DW, anything but DW, actually do it safe and get FIC
drop ins doesnt always mean better, even their pump in crappy, it heats up pretty quick,
someones car on the forum blew up because of these injectors and they didnt refund him and they tested the injectors and blocked the results from him
