IS there an equivalant engine to the 3rz-fe

[mlewis]

Hey guys heard that the 3rz-fe engines have really strong bottom ends (especially the cranks). Guys from Usa and Oz are using stock bottom ends and making 400hp before even thinking about forging out the block

Im just curious to know what other engines toyota has made that can withstand that kind of beating. Obviously there is the 2jz and the 4ag but are there any others hidden away that people know of that have really strong built bottom ends

3sge/3sgte

Strong bottom end how?

How many 3Ss have melted themselves or got knocky? Standard even.
I'd say 4As give more bottom end issues than 4Ks for example, but no one is going to say they're a bulletproof bottom end...

[Al]

As long as you don't get any det a 3s is actually tough. Will leak oil everywhere, but still tough.

[matt dunn]

would be easier to list the Toyota bottom ends that are weak,

probably none.

anything that doesn't get oil surge or detonation will probably handle way above factory HP ratings.

[Lloyd]

You could say the same of most manufacturers too though, really.

[iOnic]

Just about any 2litre turbo engine made in the past 20 years will achieve that. 400hp isn't crazy power nowadays. Even 4AGZE internals have been proven past that.

[mlewis]

Are there any others that people have had experience using or seen being used apart from the run of the mill 3s or 4agze?

.

state of tune and lack of oil or lack of maintanence have got nothing to do with how strong a motor is.

[mlewis]

what other toyota motors respond well to boost?

[Vertigo]

Pretty much all, given the right pistons and rods

[iOnic]

what other toyota motors respond well to boost?

All engines respond well to being fed more air (and fuel)...Even a rubbish 5E engine from a Cynos will surprise you with some boost thrown at it

What is your actual question? Are you looking for an engine to use for something? A 4G63 will almost double that 400hp number on the stock block with stock internals and stock ECU so 400hp from an almost 3L engine is hardly earth shattering.

[mlewis]

just been reading up about how the 3rz is used in usa for drag racing and the performance numbers looks amazing. Since they are quite rare here was thinking there must be an alternative. And would rather rebuild and work on my own motor tec rather then a workshop one as it benefits me in more ways then one

[Dell'Orto]

Buy a TB48, and make near on 3000hp

thats insane but it has to be petrol for my assignment

[wde_bdy]

You have to remember when looking at the American market they will use what they have. That is why they run 7 second 3T's, easy to find relaitvely strong and hold up to boost. The 3RZ is really common over there so they use it, 3S and JZ harder to find and more expensive so less people use them. Aftermarket support is a key thing as well, parts to fit a motor that 1 million people are driving are a lot easier to develop and make money on than a rarer import motor. Pick an end goal and a car you want to fit the motor to and go from there, also pick a budget rthat is achievable.

TB48 is petrol To keep it Toyota, 1FZFE is capable of near the same power.

[mlewis]

that could be an idea, at this stage the engine is going to be rebuild to be used, will then build up the collection of performance parts over time. just wanting something that has parts availiable for big power upgrades, still relatively small to fit into something light, and something that isnt always seen hence why i thought the 3rz

[iOnic]

Think long and hard about which one of these means the most to you. If it's uncommon and has good aftermarket support - it's either rubbish or very expensive.

Engines get good aftermarket support by being popular.

[mlewis]

now thinking about it and re reading that it makes no sense.... what would you guys recommend for an engine with aftermarket support for big horsepower? forgetting something thats a little unsual. obviously still has to be easy to get my hands on
