Help me out, which turbo to go with, need some input quick!
Ok, this is what I am looking to go for.
I am looking for a turbo that isn't going to produce a TON of lag... I was running a TD07-08 before I threw a seal through it, now I am looking for a replacement, something that is a bit of an upgrade.
The TD07-08 gave me full boost around 5500RPM and climbed upwards from 15psi after that... when the turbo came online, it was nuts. Here is a list of my mods, and what I will be running so you can get an idea, I've narrowed it down to 3 turbos, and I need your help to give me an idea of the best one for my application.
My Mods:
Large Streetport 3mm Engine
Apexi GT Intercooler
Jacobs Ignition w/MSD2 leadin coils
AVC-R
Power FC
850/1600cc Injectors w/SSX FPR
my last turbo has slightly smaller than a T78... probably about a 5-10% difference in power.
These are the turbos that I've narrowed it down to:
(needs to be T4 flanges, divided is fine, with a vband outlet)
1. AF61r by D-R Motorworks ($840 shipped to my door)
2. Greddy T78 ($500, used and in good working condition)
3. GT35r (roughly $1200-$1400)
I am looking to keep it around 15psi on the street, hoping to produce upwards of 415+ hp. Perhaps 430-450hp with the 15psi on the porting on my engine. Note this is pump gas, I won't run over 15psi without the required fuel.
for 20-22psi I am looking for 500+ hp, using race fuel on the track.
This is what I am thinking:
1.) AF61r is a great pump gas turbo, has great steetability, and has plenty of midrange and highend power. I hear it hits 15psi @ 3800rpm (assuming this is a 3" pipe setup, I am runing 4" so it might be a bit later)
2.) T78 is a great turbo for getting high hp, it's a bit laggier than both the others, but it puts out solid power.
3.) GT35r is a ball bearing turbo, puts out good power, and fast spool times. But I am worried about it lacking in high RPM (6500+) I push the car a bit hard sometimes, usually shift around 74-7800.
Well, right now the AF61r is looking like the best bang for the buck. I've done some research on the forum and I just want some input for my application!
Thanks guys,

Regardless, everytime I mention the AF61r, people say good things... I've never heard anyone doubt the turbo, or say one bad thing about it. I look forward to throwing it on, and content with the decesion I made =P

I am sure the Davinci AF61r will be a fine choice. Good luck with it.

You're right, your car isn't tuned yet. I wouldn't worry about trying to make power on that high mileage motor. Boom.
