Engine Adapters

NWOR offers the highest quality V6 and V8 conversions available. The V6 conversions are for high-tech 4.3L Chevy Vortec engines. The 4.3L Vortec engines are smoother running, run cooler, and are much more powerful than the Buicks. The Buick V6 engines, due to engineering design flaws, have bad vibration problems which are amplified when installed in the Toyota truck's rigid chassis. This is especially irritating at freeway speeds! With the 4.3 V6 conversions you have the option of retaining your Toyota '85-'95 5-speed transmission allowing full compression braking, or adapting to the GM automatic transmission.


FORD V8 INSTALLATION

Ford V8 Manual Transmission Adapter - Installation

The largest amount of requests we receive about engine conversions are for V8s. We feel, after doing numerous conversions of both V6 and V8s in our shop - taking into consideration engine availability, ease of installation, drivability, and customer satisfaction - most customers will be far happier in the long run using a small block Chevy or Ford V8. Ford conversions are gaining popularity because they are narrower, and the distributor is in front. We recommend automatic transmissions for competition and hard off-road use. However, many customers have had excellent success using '85-'95 5-speeds with reasonable tire size combinations and good driving habits.

COMMON QUESTIONS ASKED BY OUR CUSTOMERS

  • Suspension lifts? Yes
    3-4" suspension lift is highly recommended on all engine conversions.

  • Bodylifts?
    Underhood heat will be greatly reduced due to space created between underfloor area over transmission and firewall.

  • Transfer case?
    Sufficient to handle V6 and V8 conversions.

  • Toyota transmissions?
    We recommend upgrading to '85-'95 5-speeds which are very durable and will handle V6 and V8 conversions if driven sensibly.

  • Cooling?
    We recommend our heavy duty
    high-efficiency four core radiator.

  • V6 engines? Which type?
    No question! Vortec 4.3L V6 high-tech engines.

  • V8 engines?
    Ford 302 or GM 350

  • Do I need to cut and weld for V8 conversions?
    Not if you purchase the correct NWOR components!

  • Can I use my stock power steering?
    Yes, we have a high quality NWOR bracket kit available.

  • Driveshaft problems?
    Impossible to answer, due to numerous engine/ transmission combinations. To lengthen or shorten averages $60.00 at most shops.

  • Rear axle strength?
    More than adequate unless you are a vehicle abuser. "Same size axle shafts as a Ford 9".

  • Smog legality?
    Varies state to state! You should use an engine newer than you are removing. The newer engine has acceptable emission equipment on it.

  • How long will it take?
    If you are mechanically inclined, it should take 3-4 days.
