This will be on a FP4R cammed Evo IX, running E85, with a stock longblock. It will be swapped for a Buschur built bottom end in the future...but for now, it's stock. I'm thinking a Precision 6262 ball-bearing with a .63 A/R. But what about the FP HTA GT3582 with a .63 A/R? I'm looking to be on the upper end of the limits of the stock longblock reliability(525hp +/- & around 450 tq). Thanks!!

The 3582 will spool faster.

Thanks!

Will it make as much top end as the Precision 6262? Keeping in mind the restraints of my first post...

3586 makes more power than the 3582 but it has like 400 rpm more lag

Apparently these cams should not be operated past 8K on stock valvetrain (which I am currently on) & I just read the stock block shouldn't be revved past 8K as well. So which turbo would be the best for me? Which would give the most HP/TQ utilizing this rev range? Thanks!

If you plan on building your block then go with the 3586 or the 6262 their both the same, I like the 3586 better seen higher hp #'s and I think it spools faster but they recommend the 3586 on a .82 hotside

Remember its not always what rpm it spools up but also when it starts to make torque. I have a buddy with a fp red (i have bbk) and our cars boost profile is nearly identical, yet my car makes torque a good 400rpm sooner than his. Lots of other factors

Here is a comparison on my car going from the HTA82 to the HTA86.. It looks as if my car has had the biggest gains so far going from the HTA82 to the HTA86

I think all these turbos make 30 psi around 5200-5600 rpm in 4th gear on a 2 litre undivided setup.

Freddy what mph are you runnin'?

how about the T4 Twin Scroll 6262 that Shearer has? How fast would that spool. Also does anyone know what a/r Shearer offers for the TS 6262?

If your going to build it go with the 6262... if you dont go to the track and are worried about spool for the street I would go with an FP Red..

Holset hx-40 will outspool all, and outflow all.
