Hi, I am new to the forum.
My goal is to reach 550 hp, but I want to know which of the two turbines would work best for me. Precision 6265 with .63a/r housing or 6262 with
.82a/r housing. Which of the two would help me reach my goal with less pounds of boost,and which of the two will have more spool and less turbo lag?
I have almost everything, I lack the turbine, the clutch and the camshaft.The project is for street and track.
Any suggestions would be welcome, Thanks

 

There are better options for your car if all you are looking for is 550hp. We have made 550whp+ with the billet 58mm

 

6265 .82 a/r

That will do it at about 13-14psi or so leaving room to turn it up later depending on what your plans are

 

13-14 lbs wont do it on a D.

My buddy has the 6262 .82 a/r on a D.made 450 hp on pump @ 20psi.

 

Not even close..

 

Do a Billet 5857 .63 a/r on a single cam, give me a call if you need some help choosing or pricing.

 

The 5857 wil give great results im sure. for the cam, go with the bisi cam lvl2. best cams ive tested over crower, zex/comp cams

 

What is happening is that these turbines are a few friends and they are going to sell. I'm going to buy one of the two, but I do not know what would work best in my engine. So I ask you some tips.
The civic is for street but when you run go to the track.

 

i have a 6265 .82 and is great

 

Can you post a graph that shows the powerband? I'd be interested in seeing that...

 

x2

 

IIRC .. SpeedFactory made 600+ with a 6262..

 

As has been said, the 5557 or 5857 is a much better choice for 95% of the D builds out there. The 6262 or 6265 works fine but the powerband is definitely lacking for a street driven car, fine for a drag car.

 

hell yea THATS a big turbo for that motor like to see where it starts making power

 

Its just that when someone posts online a number like 545 hp on a D-Series, it makes all of my customers think they can achieve the same number. When someone says to me "Speedfactory ran 9s and made 700 HP on their D-Series, why cant i on my daily driver" i have to educate them in a manner that doesnt insult them as well as to HOW and WHY Speedfactory was able to do so.

When someone posts I made 545hp on SOHC in a thread like this, that makes the OP go get one...and then he is VERY disappointed when he cars feels like an absolute slug below 7000 rpms and only spins tires above that...which of course doesnt make for a very good street car at all.
