Forged Rods/Pistons stock crank

BadChachi

Is it possible to run forged rods and pistons on stock crankshaft?

Reason I ask is I need to rebuild or grab a new transmission. Someone told me that having a new trans would be harsh with a used motor. How accurate is that? I guess what I am trying to say is, is it best to upgrade to forged internals upon installing the new or rebuilt trans?

My thought process is that if I replace my internals it will help correspond with the new trans....if that even makes sense?? Or can I just install a new trans and not have to worry about the motor? I currently have 90K miles its been through 2 owners and other than carfax God knows what was done. I want to save as much $$$ as possible but if I have to spend to get a full setup then I will.

Or is there another route I do not see?

Are you planning on boosting your car or keeping it naturally aspirated?

NA. Not planning too. I want to but i just want to bore it and run it NA. Upgrade the trans as much in the process.

I hear the Z's are really good NA

Not really. You heard wrong. NA is a waste of money. You need to do a lot more research. The best NA build was at 370whp, and he spent a fortune getting there.

Also, unless you're planning a big power FI build, you don't need a built motor. If you're ok with 500whp, you're ok with the stock block.

really? I cant imagine FI being less costly...man..i need to reevaluate a whole lot..I am perfectly ok with 500 whp...Thats more than enough for me.. especially since i wont be doing that much track use just more spirited driving mainly. I mean I want gains just like anyone else but I figured with less track use NA would be cost efficient for the gains but I guess not.

What mods would be safe to do FI and would you go the stillen route vs like a aam tt kit? Again medium track use.

What fool said that. No, if you only need to replace your transmission you do not need to replace your motor.

Tell that person you don't want to replace the motor because you heard new motors need new wheels because then they'd be too harsh on the tires.

For moron who told you that a new tranny on an used motor would be harsh. I would be harsh on his head with a baseball bat.

Yeah, new trans on old motor is just fine.



To answer your other question, aftermarket rods/pistons with stock crank is also just fine.

Yes. Personally, I'd go ahead and upgrade the crank but there is no problem with mixing-and-matching. Just remember that a chain is only as strong as its weakest link.

Whoever this "someone" is, they don't know what they are talking about. The trans doesn't know how old the engine is - and wouldn't care if it did. All the trans cares about is how much power is being applied to the input shaft.

The engine and trans don't need to "correspond." As long as the trans bolts up properly and can handle the engine's power, you are good to go.
