    If all the car is for is racing, sure higher HP the majority of the time. But for a street car do you want to always be 5k+ in the rpm range ? There is something to be said for taking a little bit of loss of peak power and shifting the graph to the left. Makes for much more fun on the street honestly.
    You really need to pick a #, and buy a turbo accordingly.
    If your looking for 650 and under I would say get a 35r based turbo. If your looking for 700+ go gt40/6466 based.
    There is no need to lose that lower end and buy a 4094 if your looking for 600.
    Having the power on tap at all tines for 600 wheel is nice with a 35r ish turbo. But with a 4094 and running around with 600 your downshifting all the time.
    I really think for a street car , having a fat power band is more fun.
    Having driven everything in between, I can tell you this, if this TS steed doesn't wake up this 6466 a bit more, I'll take the hit and not have 700wheel on pump and fatten up the power band and get a wide 650 with a gtx35 or a 6266.

    But to answer your question, from a dig, its going to be hard for the big turbo car to catch the smaller turbo car light to light.

    Pick a fuel, pick a whp# this should pick the turbo.

    Ie , 93 octane and 600 HP is a 35r with 22-23 psi. That's doable. If that # was 700, then the 35r ain't going to cut it with out e85 or 109.

    My opinion is that everyone should experience a hard hitting 35r style turbo as a street car. While your sorting it out , if you decide you want more than 600 then upgrade. 600 should amuse you for a little bit . coning from 275 or whatever you were at. Try that first. You have a lot to sort out on your first turbo setup.

    Thank you for that info Butters, super helpful! I agree, getting into my first turbo setup 600 would be fine for the time being. Maybe even 500 just t get used to it. What's the torque numbers usually look like with 600whp, around 500wtq? Also in a 35r-ish turbo, would an HTA upgraded 35r serve for more sustainable higher RPM power than say a standard gtx35r?

    It goes like this

    Gt35r, hta3582/86, gtx3582, the hta is a forced performance upgrade.

    I had the HTA upgrade...it was good but I expected better results. The only reason I did it was because I nicked one of the blades on the compressor wheel when I was installing the cover on a brand new GT3582R.

    Id like to see:

    Steedspeed V2
    6466
    E85
    RK tuned

    You'll be in the 800+whp range for sure.

    How is the HTA3586 behind the gtx3582? Wouldn't the 86 be a bigger turbo, although the gtx denotes journal bearings?

    The only problem I have with that setup is that the car isn't able to hold that kind of power yet, I'd just be blowing up my drivetrain constantly at that power level and then have a slightly laggy system when turned down to an acceptable power level. Thus why I was thinking start at 550-600's, learn the car and get acclimated to turbo life while compiling parts to go big later on.

    But umm.. that 6466 you got is a t4 twin scroll housing? That would be tempting

    I think the HTA3582 is like the gtx3582. So more like

    35r < hta3582 = gtx3582 < hta3586

    Ahh, that makes sense. Wouldnt the 3586 and PT 6466 be in the same performance range though?

    Also what diff ratio are you guys using? Mine is currently 3.46 from having an N/A setup, wondering what I should change it to.

    Hta35 will spool much quicker than the 6466. Both will make 700 , the 6466 will do it with less boost. If goal is 650 or under HTA is your turbo, if you want 700+ go 6466

    3.2 gtx35 m3 vs 2.5 hx40 325, 40 roll both cars make a hair over 600whp but one "makes no torques"
    Skip to 4:14



    Had him 3-4 cars and i was driving horribly, banged the limiter before every shift just to flex.
    From 0-100 the smaller turbo is the better choice but if you are going to race to 140-150mph id take the larger turbo every day.

    We're the cars dynoed on the same dyno, the same weight, same gearing, both getting traction and both driven to max potential? One of those factor had to have played a role there.

    nice. A lot of variables of course....but I always loved smashing people with their $2K+ turbos as well. Their jaws hit the floor when they see you are running a diesel truck turbo that cost you 400 dollars. lol.

    Might as well go 6466 or similar sized turbo and go from there since my new engine will be high whp capable. My area is all highway, there isn't really much stop and go driving. Plus this is no longer my DD, if I take the car out it'll be to do some sort of racing.

    As for diff ratios, the popular two that I see for boosted cars are 3.15 and 2.93, am occasionally the 3.23. Any input on any of those to replace my current 3.46?

    Is the 3.46 a built diff? If so I have a built 3.15 in my car with about 1,500miles on it

    I wish we had a local here with a large frame turbo so I could see if I could tolerate the lag.

    Yea, built 3.46 with 40 % lockup. It's a noisy diff but has done it's job very well. Just want something I can depend on that'll be conducive to the new turbo setup.

    It isn't that bad, but it wasn't what I liked honestly.

    Same here 40% lock

    My Cars
    E36,E38, and E46
    If you are set on 6466 then go for it. The list of stuff you have to replace above 550 is pretty big but given time and money you will get it for sure. The problem will be keeping the HP down before the car is ready and I've seen you at the track!

    Riverview has a thorntons with e85. I think i found about 20 stations in 40 miles with e85. You realize Nick is in Florida right?
