Which turbo FP 3065 or FP 3575

[red97gsx]

Looking for the good and bad of both. Can't find much info on the 3575. I bought a brand new 3065 and have less than 300 miles on it and have a chance to get a 3575. Car is a street car running on pump gas with meth. Looking to keep pump gas and get the most out of it and still keep driver freindly for on the streets and not just track. The following are the mods i just did and all have less than 300 miles on them.

I looked in his threads and had no luck in the search unless i am doing something wrong. Does anyone have any experience with the FP 3575? I did a lot of research on the 3065 before i bought it, but can't find much at all on the 3575. Just wondering if it is worth me selling my new 3065 for a 3575 with low miles on it, if their are any major benefits.

Thank you very much for the link. This helps out some and i don't know why it did not come up when i did a search for 3575. Anyone else run the 3575 and 3065 to compare. Thanks,

What else do you need to know? The 3575 is bigger than the 3065 which is capable of putting out more power. The only downfalls is that the 3575 is quite laggy. It may not be to big of a factor for you because you have a stroker motor and it look like you're all setup for it with 280s cams.

You should really consider doing research research beforehand.

i thought FP discontinued the 3065 because they replaced it with the HTA35r which spools faster and makes more power, that should make your choice easier if they dont have it anymore.

They still do make the 3065 but not the 3575 and red97gsx already has the 3065 and 3575. He's trying to decide which way to go.

oups, you're right.
Sorry for posting misinformation.

Read the thread!

Beside I wouldn't thrust those no-name Comp turbos, which is not Comp Performance, that supposedly capable of 600hp. And it just make me that they have a triple ball bearing upgrade. And if you put that much money on the engine why would go for that turbo? You're kissing your engine goodbye.

Don't like the 3065?

Personally even at 30-31 psi on my 3065 I haven't really come close to reaching it's potential on pump gas. For me IMHO if you haven't maxed out a turbo you shouldn't upgrade it. Stay with the 3065 and run it out to 30+ psi and you will be more than happy......especially on a stroker motor.

3582HTA in T3 hotside form.

My normal response would that those are two VERY different turbos, why are they even being compared, and the 3575 is probably not for someone that originally decided on a 3065. But in this case, with a 2.3 liter, I feel that the 3065 is really too small of a turbine side for that motor. The 3575 would a better match IMO. I drove a local NEDSMers galant with a 2.3 and 3575, and it was pretty ridiculous. It didn't feel terribly laggy, but typical set boost comes in somewhere around 4800-5k rpm IIRC. Someone with more experience than me can chime in here. Whether or not this is too laggy for a street car is up to you.
