The pins shown all seem to be parallel wall - taper pins are not only lighter but have the material where it is actually needed - the highest bending and sheer loadings are at the centre and the ends are only lightly loaded. It should be possible to source some of these stronger, lighter pins from the aftermarket - may be worth checking out? Again, not familiar with the "import" market, but some pistons are available in 'short pin' lightweight versions, which also reduces the bending stress on the pin, but increases the direct loadings - may also be worth checking out?
What the difference in the from a pin that floats and one that's pressed? ...other than how they are assembled and work. Can the same pin be used as floater or pressed?
Thx for the tip Jay just upgraded my HEMI wrist pins to .250 thickness wall as you said its a boring piece and I was made fun of for upgrading to it on my build of 1500HP on race gas.
Hey jay what do u think about converting a press pin piston to accept a full floating rod.i really need high compression Pistons but can't find any full floating ones for my d series Honda na build.help please
Howdy. I have a new-to-me 1998 Nissan Pathfinder 4x4, automatic, 3.3L VG33E 4th VIN digit "A" motor, made 10/1997. It has one or more bad piston wrist pins, and a confirmed bad crankshaft due to excessive bearing failures from oil loss. Does anyone know if the pistons in a 1996-2004 Pathfinders, QX4, Frontier, or Xterras can be removed and reinstalled through the bottom of the motor (oil pan), with the motor still installed? I also have a bad crank so I have to have it removed and machined too. The rest of the motor is clean, no oil burning, and low miles (165,000). I hate to swap it for an unknown possible problem motor if I can do it this way instead. I haven't been able to find anyone online who has accomplished this, but maybe it's not possible due to clearance or whatever. Do ya know, or take a guess, if ya been under one of these models with the oil pan off and crank out? Thanks much!
Hey there, Buddha Bills! Good question! Ball Bearing turbos spool faster initially but most importantly transient boost response is a lot better with ball bearing. They are stronger and more durable as well.
i just put my engine together...but I'll be going back in to do some upgrades in ~ a month...I'll be contacting you for some of your giant pins...thanks Jay...oh yeah....FIRST! never did that before...lol
Hey Jay, So I purchased some Speed factory outlaw Arias pistons for my B-Series motor. My question was, they came with wrist pin buttons to hold the wrist pins in instead of cir clips. What's your take on that for a 50/50 street/track car?
Buttons are really just for engines that are pulled down frequently, like drag and sprint engines, with the main advantage being speed of assembly and disassembly. ARIAS 'should' offer them with more conventional pin retainers and, in some instances, the pistons are already machined for this - don't know about your instance, though. Personally, I would not run them.
Wrist pin buttons are nothing new and have been around for a long time, for example Lycoming has used them in aircraft engines for decades. The downside for a button is you're adding weight IF you're using a short pin. There was a period of time that people had issues with circlips vibrating out OR being spit out because poor installation or alignment and buttons seemed to be the sure fire way to solve the problem. As machining has evolved there are less and less problems to be had with wire retention of the piston pin however for those of you that have used buttons they're really easy to install were as the wire locks require a steady hand to get into place. There isn't a "wrong approach" here and you generally see wire retention based off of costs and nothing more.
REALSTREETPERFTV would they cause any problems in a street car vs cir clips? Because from my observation, it seems the buttons are only held in place using the piston rings which I assume would allow some side to side play in the buttons/wrist pins as opposed to the circlips which sits solid in a groove.
Good video, Whenever I bought a new set of rings for my cp pistons I actually got the upgraded pins also, It was alittle while back (purchased from real street) But great customer service, Even gave me the phone number to contact real street's engine builder if I needed any help and for questions on ring gaps. Thanks again. My longblock is complete, I'm working on getting my fuel/turbo setup and hope to see real streets dyno eventually, going for 600+whp maybe 1000whp if I get the proper turbo/fuel setup
+Never Enough Boost thanks for the support. let us know what parts you still need and we will do our best to get you what you need to get back on the road asap. sales@realstreetperformance.com
What about the piston sring in cylinder people dnt believe that and great video just like oil squirted in Honda engines in block cylinder to under piston awesome putting the air plane setup like wankel engine awesome rotary
If only every video could be this direct, thorough, and informative. Ahh, what a world that would be.
Thanks Wayne, i appreciate that feedback!

Damm this is good info ! I didn’t realize how an important part that the wrist pins come to play 👍
Good video! I did upgraded pins on my 2.2 4g63 build
What the difference in the from a pin that floats and one that's pressed? ...other than how they are assembled and work. Can the same pin be used as floater or pressed?
so a upgraded pin would be good to have in a high torque i6?

Are titanium alloys ever used for big power forced induction engines? You could build a big thick pin, but wiegh only half of a steel equivelant.
With upgrading the wrist pin is it required to rebalance the new pins the pistons, if I didn’t purchase them at the same time?

Does upgrading piston pins change the standard on oil viscosity?
what will the step in weight do for harmonics? probably not good right?
Great videos... Thxs Jay
Shoot man learned a lot from this vid ( and his other vids too) #RTP4LYFE ;) 😎🚗
Is it true that ball bearing turbos are better than Journal bearing turbos because of the lag in journal bearing turbos?
Hey there, Buddha Bills! Good question! Ball Bearing turbos spool faster initially but most importantly transient boost response is a lot better with ball bearing. They are stronger and more durable as well.
Thanks
Fuck. My engine builder never mentioned anything about upgrading my the pin size with my JE pistons 😩
i just put my engine together...but I'll be going back in to do some upgrades in ~ a month...I'll be contacting you for some of your giant pins...thanks Jay...oh yeah....FIRST! never did that before...lol

What do you think can do wrong? Maybe if I understand your fears I can address the concern more directly than I already have.
Thanks
Jay Meagher because the buttons are only held in by the bottom oil control rings, im afraid they may not stay in place.

I have a vw golf 4 r32 turbo with wossner pistons do u do upgraded pins

No LS parts?
Hey Matt. We can get them. shoot me an email with what you are looking for at Sales@RealStreetPerformance.com
Can you open comments on the Macarthur/Furtick video? I think it would be helpful for Christians to have a healthy debate about the clip.
I actually thought these are pins you insert into your wrists surgically.
