Gs570sc

Hey guys I have a 03 gs430 and I was debating on either swapping in the 3urfe and super charging it or doing a ls2 swap but I have also heard upgrading the stock engine with a super charger or turbo is good too. I'm leaning on more of the sc 3urfe swap but wanted ideas on how much work it would be to do it

MedicalDoc

U mean the 3UZ?

I think he's talking about a 3UR-FE 5.7L ...
Should be a weekend swap...

Also, you're the second person to ask this week.

Well this is a very unique swap plus it's a 5.7l and with the super charger it would make any where from 504-550hp on stock internals plus I heard the 3urfe engines are pretty reliable

lol. that is humorous. but at the same time some might be very adventurous and have deep pocket books to do so. having been down this road i feel like if i could do it all over again it would be a iron block 4.7 with 3uz heads and single or twin turbo'd. reason being. alot less headache than custom fab a 3ur 5.7 liter. plus thats a huge engine. it really is. plus im sure very costly. the toyota 4.7 iron block from a tundra has alot of potential. bigger displacement. iron block for less distortion under high cylinder pressures. fits in gs engine bay without modification. 3uz heads flow really well. cheap to acquire. in my thread back in the gap when i did the single turbo 4.3 liter it made 453 horsepower to the wheels at 13psi. so thats a crap load of power. if it was built with forged internals and a beefy trans. it would make six hundred without effort. and could actually use the stock ecm for driveability. just run a piggy back to pull timing and probably run a 9:5:1 compression ratio piston. it wouldn't make sense to go thru all that effort shoving a toyota 5.7 liter in it. thats an amazing amount of modification.
the 2jzgte is awesome and capable of crazy horsepower to but the off the line takes some getting use to. I haven't done a high stall coverter yet but theres a reason the audi RS7 runs a 4.0 liter v8 and not a v6 or inline 6. DISPLACEMENT.

How big is that 5.7 vs the stock I'm trying to find the measurement for both to see how it will fit I'm still doing some more research before I pull the trigger on it

just stop by your local Toyota dealership and pop the hood. their ginormous. plus you would have to use the transmission that comes with it and im sure its a behemoth too.

Lol damn I was hoping their would not be so much modern to make it fit lol

Tundra 5.7 is epic. i like that you're thinking outside the box on the car! It would be sweet to do that motor but yes its a big *** motor, trust me I know
