500hp normally aspirated

[sigmatero]

What would you all suggest for a Toyota engine to get 450-550hp without forced induction? Needs to be 6 cylinders and 4.5L or less and also have aftermarket parts fairly available (not a real oddball engine). Can run high compression and doesn't have to be real streetable since it's for offroad racing. Gots to be a Toyota

Thanks folks.

Nope;p not going to happen

Only 8

You might get those horses from a 1uz,Lexus v8!

Start with a Chevrolet LS1 and put a Toyota intake cover on it..

 

[sigmatero]

The Class-7 Ranger guys are apparently getting around this hp (or more) with a 4.5L V6 Busch Ford engine. What's comparable with a Toyota engine?

You would have to make 2 hp/ci to make 550 horses with 4.5 liters. Thats about as full race as you can get, you would have to have so much cam and port size that it would blow really hard at low rpms. I dont think toyota makes a motor you can spin up that much (at the very least that meets your criteria).

You do realize that 550 hp is a whole hell of a lot, right?

The most new 4.5 3 coils engine from Toy have numbers around 220 HP .. with TRD supercharger it can raise it to 280 in better case with intercooler and plenty of fueling mods ..

I thought with major mods can archive 300 HP .. but 550 .. uff !

You can probably get 500hp out of a 5VZ-FE doing osme custom head work, regrinding the crank, etc
But you would need to turbocharge it.
NA just isn't going to happen.

Also, you would need to run a stand alone fuel injection and ignition.
So it wouldn't really be toyota.

The old adage goes...
How fast do you want to go?
How much money do you have to spend?

Start with a 2JZ motor from a Supra. Super strong 6 cylinder under 4.5L.

X2. Guy brings his over to his GF's house down the street from me and I guess his is pushing over 400 (with a turbo) and will be in the vicinity of 570hp after his next round of upgrades

 

[scottryana]

I know the thread says no forced induction but 2JZ motors can make 700-800 hp with a big turbo, using the stock bottom end.

The 1FZ 4.5L has little to no aftermarket tuning support... with that said, you could build a heck of a nice engine with one.

 

[Nagalfar]

The stroke is to long, it's made for torque and not a lot of horsepower.. the bottom end is to soft for making the high RPMs needed for making horsepower... it would be a lot cheaper and more simple to just go with a Oval or Bowtie... the Ovals weigh in about 110 pounds less than the SB Chevys..

 

[sigmatero]

Bummer, I was really hoping there would be something to compete with the Ford engine.

 

[Tapage]

maybe you need something like ..

Put a 20lb. bottle in and love the NOS. Makes those short , WOT hill clims really fun.

Not necessarily.

There are other yota engines than the ones that they put into trucks guys. What about a supra engine??

Im not sure a NA supra making the kind of power he wants would have any bottom end at all, especially considering the weight of the tires its spinning and the weight of the truck.
