I wanted to start this thread to gain some knowledge on a few different things and over all just learn more about turbocharging. Ive been trying to learn and read a bunch about the different types with ball bearing, or non ball bearing, billet compressor wheels, the actual housings, what the series numbers (like 40r) mean etc. I will eventually be in the market for one sometime down the road so im trying to better myself with understanding the differences with different types. Im sure ill get flamed and called a dumb ass for asking but, with all the turbo’d cars on here and everything from 250hp turbo civics to 1200 Hp supras, evos, jeeps etc etc i think its a good place to ask and for me the best way to learn is to ask or read open discussion of others opinions. I see a lot of lsx motors running 88mm turbo like the borg warners which seem to be pretty cheap compared to others. In my case i dont think such turbo would suit me well as i am limited and need to shift by 6500 RPMS. What type of power band would an 88mm borg warner make and what would tye power band look like? When does boost begin or does that all depend on the motor? Ive seen some precision 76mm billet ball bearing turbos do extremely well on a modern hemi set up. Starting to build boost by 1600RPM carrying all the way up. Why the difference in the two? Teach me some shits.
journal bearing turbos are cheap and easy to rebuild
Ball bearing turbos spool quicker and more efficient as well as allows for higher rpms
billet wheels/turbos are lighter, spool quicker and can handle bigger thrust loads
The higher the displacement/hp the bigger the turbo you can/should run as it will spool it quicker. Lots of hondas run smaller turbos becuase itd take forever to spool a 42r with a 180hp motor… IMO in the charger use the biggest baddest turbo you can find, youve got enough motor to spool it quick.
I was gonna use a 42r in my old del sol but only becuase I planned on using nitrous to spool it quicker otherwise I wouldnt be spooling till like 90mph lol
just my $0.02
Here is my recommendation-the new GTX wheels are badass.

i need a set of twins. BAD.
I tell you Im gonna go with a gtx30r and u tell me go with yours instead but reccomend a gtx to him anyway lol…
nah but yea gtx is the new and best shit out there, also really expensive. I kinda think you could go with a cheaper brand turbo though as again youve got ALOT of motor to spool your turbo. Most gtx people I see are hondas/dsms that NEED the quicker spool time as they are very low displacement engines.
Needs something, those bottom ends will do over 1000 w/o issue
STOP it mike aka situation… jk lol
Comparing apples to oranges bro.
My motors tiny, his motors huge, I NEED ball bearing and billet wheels, he doesnt lol.
I know what you’re saying, but he wants to make crazy HP (like 13-1400)
where’s the fucking like button!?!?!?
This^^^^
Love4boost you beat me to it.
Ive read a lot of “ball bearing is more polite on daily drivers” type of talk and that with journal wheel its like on/off switch with boost. All i know with turbos is MM size so far anything like 3740r im fucking lostt.
Go look around on Supraforums (dyno section maybe). Some dude on there did detailed logs of bb vs. journal bearing turbos spool characteristics
Invest in the stock market.
Ill try to find it.
Click the turbo link I posted. Look at the ‘compressor’ specs. See where it says 79.8 mm? That’s the size of the inducer. So when someone says they have an ‘80mm’, they are referring to the size of the inducer.
me too.
a nice pair of Blondies.
Death, check your PMs
Just saw. Thanks for the offer! Ill let you kno.
