1998 toyota tacoma 2wd 2.4l 3rz question.

I have a 1998 toyota tacoma 2wd with a 2.4l 3rz and im wanting to make it a mini truck for speed should i go about getting the stock engine rebult and ready to handle boost for a turbo or just engine swap it?

 

Both options have their pros and cons depending on your goals, budget, and mechanical experience. Here’s a quick breakdown:

1. Rebuilding and boosting the 3RZ-FE:
   
   • Pros: The 3RZ is a solid engine known for reliability, and with the right internal upgrades (forged pistons, rods, etc.), it can handle decent boost levels. Keeping the stock engine maintains simplicity with mounts and wiring. Turbocharging can give you a fun, responsive setup without needing to deal with the complexity of a swap.
   • Cons: Boosting an older engine will require a full rebuild to ensure it can handle the pressure. You’ll also need to upgrade fuel systems, tune the ECU, and possibly swap in a stronger transmission if you're making significant power.
2. Engine swap:
   
   • Pros: Swapping to a more modern engine (e.g., 2JZ, LS, or K24) can give you more power potential out of the gate and may already have better aftermarket support for high-horsepower builds. A swap could give you more power reliability if you want to push the limits.
   • Cons: Swaps are complex, requiring custom mounts, wiring, and possibly modifications to the transmission and drivetrain. It’s also usually more expensive and time-consuming than rebuilding.

If you want a reliable, moderately powerful setup, rebuilding and boosting the 3RZ could be the way to go. But if you're aiming for serious speed and have the budget, a swap might be worth considering. It depends on how much power you’re chasing!

 

generally, a motor build isn't worthwhile unless you've got $10k to blow on entertainment purposes. all the parts add up, especially the parts that break.

 

Swapping the motor is likely to exceed the cost of rebuilding the motor. Your choice.
