Question about turbo

[turbo dragon]

Im looking at a turbo upgrade kit and it offers the same turbo in four different bearings ( +$140 journal bearing, +$400 ball bearing, +$250 billet journal bearing, +$980 billet ball bearing ) I know the ball bearing is better than the journal, but does it make more power to make it worth the extra money and is the billet worth the extreme extra money.

Ball bearing....better response all the way around.....Longevity.

If you have the cash I would just do the BB upgrade. Not sure what performance advantage the Billet wheel adds. Someone more knowledgeable then me can chime in.

[turbo dragon]

thanks, I thought thats what the bb did but I didnt know if it add more power too, still wondering about the billet though

[Apex i ITR]

Well technically it does....more power quicker and held up top longer.

[turbo dragon]

cool so what about the billet what makes it so much more

[Apex i ITR]

On that i have no clue. I assume its probably lighter which means it will spin faster and be less wear on the bearings.

What turbo r u looking at bud?

[TouringBubble]

I believe that the billet wheel is lighter. Might be "stronger" too, but that only comes in to play when stuff breaks. A billet + BB turbo would have much better spool characteristics and reach a higher RPM than a standard turbo.

awesome, that make since, but is it worth the extra 1k

A better question would be what are your goals? Do you plan on doing road courses? Autocross events? Drag? Just plain daily driver use? That extra K is getting you a more responsive turbo. Do you have a 2.0?

[Apex i ITR]

I would at least do Ball bearing so you have some longevity out of it.

[Hikaru]

What are your plans for the car? Are you on a 2.0? And aren't these turbos kinda obsolete with the trends going toward high output stock frame turbos? Seems to me you could get a BBK-B, injectors, a tune on E85 and make some serious power with good spool for less money. Get a dual map switch to run 93 with ECU controled boost for econonmy and you are good to go. Port the stock manifold later for some extra power. Just my .02

[turbo dragon]

Im still on a stock motor for now and not sure if I want to do a 2.0, 2.3 or 2.4 build when the funds permit. but I already have the head port and polished and rebuilt and the mani has also been ported. the most Ill do with it is drag and the occasional autocross, other than that I drive it around town on the weekends and to car shows/meets, but I also want it to be reliable while it is on the road

[blkonblk2red]

what are your power goals?

[Hikaru]

I would encourage a BBK-B. It will still have good spool and power on 93 and a 2.0. Later if you decide to build the motor and turn up the boost it will make upper 400's in power I believe. If then you decide to swap turbos to a bigger stock frame like a black then you can get good resale outta the BBK and won't have to swap manifolds. On a stock 2.0 and 93 I don't think any turbo can match the well rounded nature of the CBRD turbos. They really are the best balance for a daily street car IMHO.

[turbo dragon]

Im hoping for somewhere between 700-800hp if possible

[Hikaru]

jesus!!!!!!!! I'm out. Good luck using that anywhere.

[WRC-LVR]

thats not likely with a BBK. 350 - 500 is. I dont think any stock frame turbo will make that power. Question is will your drivetrain hold that on a DD ? 6 spd dont even think about that..it 'll shred it. 5 spd might but you will need to upgrade the tranny and input shaft at the very least. Shep or TRE.

Turbos that make that kind of power are not great daily drivers, boost and power comes on too late making them not fun to drive in traffic etc.

^ I was recommending the BBK cuz I figured he wanted a fun street turbo. But It looks like he wants a 35R and bigger. Which, as you stated, won't be very much fun on the street or anywhere really. Except maybe a drag strip.

[turbo dragon]

glad yall said that, kinda opened my eyes as far as driveing it on the street and being no fun, think I may settle for around 600 hp, I think that would be good on the street and strip

[blkonblk2red]

^ thats still a lot of power .... you won't be able to get away with that unless u do a 2.0 build or a 2.3 2.4 .. stock motor is not recommended in pushing over 450lbs of torque... so unless u plan on building... i would aim for high 400s

[Hikaru]

^Totally agree. OP what kind of power are you running now? It's amazing what the difference between 300 wheel hp and 400 wheel is! It's quicker than people realize.

I'm hoping to get Ryan to chime in here but here is my perspective on his old MR set up: This thing was stoooopid quick. BBK full turbo, S2 cams, ported stock mani, intercooler, 28 lbs. of boost, 93 octaine, 780 injectors. A tad over 400hp on the Forged Dyno Dynamics rollers. Throttle response was awesome! Pulled very, very hard. A very fun street setup! Responsive enough for an autox. Prolly would run mid to uppermid 11's. I've wanted this exact setup for a while but with all the bad luck I've had funds keep getting pushed back. I would prolly swap out the BBK-B and run stock cams just cuz I think it's better and more comfortable for a daily. If you drive your car a lot responsiveness of the turbo is what makes it fun. When boost starts slamming you in your see at 5500 rpm and later it kind of kills it for me. Not to metion going over 500 hp the clutch and drivetrain becomes a big issue.

[turbo dragon]

Im planing on doing an AMS 2.0 rebuild myself before I get the turbo kit and Im also going to get shep to rebuild my tranny and T/case too so the weak links after that should be axles, which I am planning on replacing as well
