ok my car is ready for a new turbo. I have an evo 9 MR with full bolt ons. I been considering the FP red turbo. What would be the best route to go with Ball bearing or journal bearing? Also i heard that these turbo tend to have oil leaks is this true?

PS: my goal is 450-500whp

 

I think the red will get you your goal but with E85, Also the ball bearing vs Jb its all about how fast you want boost coming in. I believe they both will make ard the same power but the ball bearing will get you there faster with about a $1300 more than the JB. I just bought the FP green jb i hope to make just around 460-470 as well.

 

What fuel? A green will hit your goal no problem on E85.

If you can afford it, ball bearing is better. More resistant to oil starvation, better transient response, and a bit faster boost threshold.

 

I've had both. The JB Red hit 480HP on gas at 35PSI on a 2.0L.

The BB Green HTA hit 482HP on E85 at 24PSI on a 2.1, before running out of fuel pump volume (E85 needs 30% more fuel volume to get same HP)...

BB is more reliable (although I never had any issues with either one) and hits a little quicker, but either one would get your HP target easily. I'd recommend the BB. I've never had FP turbos have oil leaks, as long as the lines are properly installed.

 

I put 70k on a jb green so I would say the jb is very reliable

 

The biggest issue with FP Journal bearing turbos is that it's difficult for the stock evo baffling to support constant oil flow to the oil pick up tube (and therefore turbo oil feed line) under hard cornering.

There are two documents on FP's website that talks about it. They have helped remedy the issue by getting the turbo oil feed right off the oil filter housing instead of the stock location at the head because oil pressure is higher and more consistent down there.

Ball Bearing turbos are more resilient and can easily handle intermittent oil pressure issues.

That being said, i'm still buying a JB FP black because I can't justify the extra $1300.00 more just to spool 400rpm faster. I mean come on! It's two times the price for the same turbo with a different bearing type! As a result I will get my oil feed from the oil filter housing and baffle my oil pan better. For those of you with MIVEC, this is important too. You're MIVEC gear needs constant oil pressure to operate correctly.

Who told you it spools 400rpm sooner? That's about the difference in the MHI vs SS, not JB vs BB.

 

This BB might spool 40rpm faster, not 400.

 

Thanks guys for the advise and info. I been doing some research on turbos. This is totally of topic but has anyone ever ran any of the garrett turbo GT or GTX series?

 

Per the engineers. English told me they saw 100-150 rpm difference testing an FP green on an Evo. So boost threshold doesn't make it worth it. Transient response and resistance to intermittent oil are why I went with BB knowing my car would see track time.

 

Care to tell me what I'm doing wrong? Brand new feed from head (as FP now recommends for their BB turbos) FP oil line, BB restrictor filter.

Sealed catch can with 10AN out of the valve cover and 10AN to the intake tract. Stock PCV system.

Still getting oil pushed in to the intake.

Car has less than 5% leak down on all cylinders and made great power with the turbo (515whp at 29psi on e85). Stock internally except for a set of GSC cams.

Still need to measure crank case pressure. Not real sure where it would be coming from with the leak down numbers I have. Anywho, sorry for the tangent.

Both turbos are solid units, but unless you road race all the time I would stick with a JB.

 

How much oil? Mine leaks a bit. But it's not like my car smokes or is spooging oil out of the BOV. I think I had a 1-2 ounces of oil in the intercooler (just a thin film), and the licp right after the intercooler, after 5k miles. Seems like a trade off for the performance to me.
