Q:stock rods with floating pins

[panter]

hi
has anyone done that conversion? I have wiseco pistons with floating pins and im trying to figure out weather to convert original rods or not!
goal is around 300hp..ive read here that stock rods will handle that?
turbo is gt2876R
thanks!!

Actually with good tuning the stock rods AND pistons are more than up for 300HP.

Well the Wiseco pistons can be setup either way, either with the c-clamp for a free-floating setup or the wrist pins can be pressed... Thats the beauty of Wiseco's pistons ;)

Stock rods should be fine for the hp your looking for.

- I perosnally have the Wiseco Pistons w/Free-Floating Setup on Pauter Rods :)

Just remember that most people are giving answers that relate to the beta 2. From your avatar it looks like you have a J2 elantra, so the answers might vary...

The interals of the beta I and beta II are close enough that the answers provided will work for either application.

They use different rods and pistons, don't they?

[panter]

i only know that the bore, stroke and etc is exactly the same...
i dont think that they started using different materials but who knows!
ok today I pushed the pins in and it went with no problems...maybe i did a mistake by not heating the rods but it went really well...so here is my question to you:
If i lieave the pins as in stock so I will not put the stoppers in? at least i think that there will be no need for them?
(ps-are your lantras also MAP based from stock? )
thanks!

The 01-03 Elantra is MAP based, 04+ use MAF.

if you just pushed in the wrist pins without heating it... and you put that in the engine, your looking to have some serious problems down the road...

You heat the rod so heat expands the hole that the wrist pins go into, then you put the wrist pin in and cool it so the rod contracts, holding the wrist pin in place. If you just pushing it in with your finger, well, think about that...

Also, in a free floating setup you still have a c-clamp that holds the wrist pin in place... (ie: so it can't slide out)...

So again, before you put your engine together and possible do some damage, you might want to think about what your doing.

Either you need to take this to a machine shop that knows what their doing... or get some new rods and just go do a free-floating setup.

I'm running a Beta2 engine in a tiburon w/MAP sensor setup (03' i4 tib).

yes i understand the heating part but it is impossible to push the pin in with the finger! I used big press and couple special devices for that! I think the heating part is just for the pin going in easyer and being able to push it in with the finger or another option is to make the pin really cold then it contracts and then when gets to normal temperature goes to normal again...

right now it is impossible to move the pin in there with the fingers...

im just thinking if I shouold put in the lock for safety...
just some pics...

Pictures no worky, and I would love to see 300whp out of a Beta I elantra.

sean - you just suck at the internet. my restricted *** computer here at work is showing them

Isn't your engine a 1.8? If so, then the bore, stroke, etc can't be the same. We have 2.0's.

The equation for displacement is #of cylinders X .7854 X Bore X Bore X stroke

So if they're different displacements, how can the bore AND stroke be the same?

[panter]

no the new engine is 2.0!
tomorrow i installed the fourth rod also and came to the decision not to put the locks in because something has to move...when having floating pins then rod is moving as much as needed but when non floating then pin inside the piston has to move little bit..that way piston gets aligned in the place where it needs to be..that is my logic..hope its right :)
