2JZ-GE stock rods strong, pistons weak??

I am a new owner of a 2002 Lexus IS300. Like most people I have been doing research to figure out which route I wanna take to make my car have about 500rwhp. I have been doing HRzzz and hrs and weeks of reading.

I was wondering if ANYBODY in the IS community could clarify..

When building a VVTi 2JZ-GE, to make the engine reliable for +500rwhp, it is a must to replace the rods and pistons. Simply because in this engine they are not strong enough.

k954triniz started a thread asking about what it would take to make his 2JZ-GE reliable for 500rwhp. Cruzanspeed was post #30 of 30 and said he had an experience where he worked on a IS300, engine blew. It was pushing 605whp on stock rods and gte pistons. The rods DID NOT FAIL, a piston ring land broke.

Can anyone clarify this?? If not I'm sure after a few more hrs of research I will find the answer. Just hoping you guys could save me the time if you knew. Thanks in advance. If and when i find out, I will post again whether this is confirmed or fantasy?..

GE internals are smaller/weaker than GTE internals. So for big power I would go GTE internals or forged pistons and stronger rods. you could get away with 300-350whp with GE internals.

Pretty sure the ring lands are the weaker point on either piston. I say "weaker" but not necessarily "weak"
The GE rods are much thinner than GTE rods.

There were rumors going around that '01's had GTE rods and/or VVT-i vs. Non-VVT-i had one or the other, blah, blah, blah. Never know what's actually true.

Safest bet, just buy the GTE internals. OR if you can still find one, buy the entire factory assembled short block.

I could take a photo of my rods I just took out of my 01 GE vvti. would you be able to tell by a photo if they were GTE or GE style?

Personally, if you are going to have the rotating assembly out I wouldn't risk running GE rods. For the peace of mind I would just put a full set of reman GTE Rods and pistons in. I had the same question and did the same hours of research trying to save the money. Bought GTE rods and pistons then decided to go with BrianCrower rods and a set of used CP pistons(killer deal)

here is the difference, just build my engine 4 months ago, this is a picture of the difference ( my actual rods and pistons ) the picture in red you can use as reference to make sure you are getting actual GTE pistons not GE's // GTE should be good till about 700 ponds or torque and over 800 horse power // now keep in mind a lot of other factors are important, like a really good tune and the right set up, enough fuel and injectors ect ..

You can also use internals from the NON-vvti GE block (rods are same as GTE). They are very, very stout, and they give you a higher CR than the GTE (10:1) with the GE headgasket. Provided you have a competent standalone and tuner, the higher CR should not be an issue. You don't need to lower compression using the GTE headgasket either.

Also, I'd bet money that NO 2001s came with stronger internals. Urban legend.

^ this is the only rumor I think was proven to be true.

It's easy to get confused with all that stuff. I still suggest a complete factory-built short block!

Just checked my rods from my 01 ge vvti and mystery solved. They are the thin version. I was hoping for thick cause I could turn around and sell them quicker than GE rods. Oh well. We can put that to rest.

From my reading here on the forums, I'd feel comfortable running 450whp on GE internals with a good tune and meth injection to keep temps down. But yeah, for 500, I'd say go with some GTE or GE non-vvti internals. I'll probably go GE non -vvti when I get to that point, I'm trying to keep a high compression engine so I have a little more pep on the low end.

Didn't know the difference was that noticeable between the two. Where do you buy reman gte internals ?

Funny you took those pics 4 months ago. They look strikingly similar to ones on Supraforums circa 2011.
I'm curious how pistons and rods are remanned myself. Do tell!
