Toyota Premio/Allion Tuning

"Thanks for reading my Toyota Premio tuning article."

Replacing the popular Corona the Premio and Allion were released in 2007.

It shares much with the Avensis mechanically but was only sold in Japan.

The Premio/Allion is a great tuning project to play with. If you do your research then you can create an awesome Premio but don't be fooled there are lots of parts out there that will simply not suit it read our unbiased guides first.

Handling/Suspension upgrades

Handling modifications are usually your first port of call for the Premio/Allion.

If you set the toe out from one to a couple of degrees on the front, and add a bit of negative camber then cornering will substantially benefit a front strut brace will also help a great deal and will keep things nice and tight and properly setup.

Drop the car by as much as 29mm - 40 mm. and fit motorsport grade stiffer dampers, bigger drops will need other modifications in most instances.

Our aim in Premio/Allion engine tuning should be to increase peak power and Torque at the top end.

Spending a little money on the top engine and handling parts will transform your car into a potential super car beater.

Smaller engines do not provide much of a return in terms of power so start with a bigger engine. Engine swaps are a good option if you have a small engine size.

Premio/Allion Tuning modifications.

Typically these performance upgrades are usually installed by our members, decide how far you want to push your car before you get going.

First generation 2001-2007

  • 1.5 L 1NZ-FE I4
  • 1.8 L 1ZZ-FE i4 (2WD/4WD)
  • 2.0 L 1AZ-FSE I4

Second generation 2007-

  • 1.5 L 1NZ-FE I4
  • 1.8 L 2ZR-FE i4 (2WD/4WD)
  • 1.8 L Valvematic 2ZR-FAE, from 2010
  • 2.0 L 3ZR-FAE I4

The 2010 versions of these engines were revised and fuel economy was improved.

Getting the right sports parts for your planned usage of the car is vital. Stage 3 motor sport parts just don't work well on the road and will make the car undrivable.

Best Engine Mods for your car

  1. Mapping - remapping provides the most advantage in terms of cost savings,  aftermarket ECUs, and piggyback ECUs are all alternatives.
  2. Fast road cams are one of the most significant mechanical changes, but they must be installed by someone who knows what they're doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.
  3. Intake and Exhaust - Note that on their own these mods will NOT ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction.
  4. Upgrades to turbochargers and superchargers - forced induction is the most efficient approach to increase air supply, allowing you to burn more fuel and make more power. It is one of the most costly upgrades but provides the best gains.
  5. Head work - The goals of porting and flowing the head are to get air flowing into the engine while removing flow restrictions and turbulence.

Typical stage 1 mods often include: Sports exhaust, Alloy wheels, Remap, Lighter flywheel, Suspension upgrade (drop 29mm - 40 mm.), Panel air filter.

Typical stage 2 mods often include: Power/Sport clutch, high flow fuel injector, fuel pump upgrades, Ported and polished head, Fast road cam.

Typical stage 3 mods often include: Adding or upgrading forced induction (turbo/supercharger), Sports gearbox, Internal engine upgrades (pistons/head/valves), Competition cam, Engine balancing.

Your targets when modding your car should be a flat and wide torque curve. You don't want all the power to be at the top end unless you are creating a motor sport car.

In this article we shall give a limited introduction to the best mods for your car, but we'd encourage you to spend some time on the site looking into the details of each type of performance mod.Fast road cams offer one of the biggest performance gains for your money as far as a single sports parts goes on a NASP engine.

The intake and exhaust flow play a huge factor in your cars power band, but be careful here, getting this wrong can upset the idle and make the car impossible to drive in traffic. You'd need to follow a camshaft upgrade with other mods and finish with a performance chip for the best performance gains.

When pushing up the power you will need to look at to the fuelling. More power needs more fuel.

Frequently power losses, and erratic idling after performance upgrades are done can usually be traced to fuel delivery or timing issues. To get sufficient fuel you may need to upgrade the injectors on your engine.

Uprate the fuel pump to cope with the extra fuel requirements of your tuned Premio's Allion uprated injectors.

Premio/Allion Intake and Exhaust Tuning.

Breathing mods are usually next up. Please note that WE DO NOT RECOMMEND INDUCTION KITS, unless you have tuned your car a lot and are finding that the standard air intake has become a restriction.

For most Premio & Allion  engines TorqueCars would suggest you just go with a washable panel air filter. On heavily tuned engines and turbo vehicles an induction kit will help release the power providing you address the problem of supplying cold air.

Sports exhausts can help balance the flow of air through the engine. But if the exhaust pipe is too large, ie: it's over 2.5 inches bore, you will lose much of the exhaust flow rate and end up losing power and torque.

Getting the cylinder head gas flowed will allow you to get more air into each cylinder. This is definitely a job for a professional with a flow bench. When you tune up your Premio Allion you will reach a point that the standard clutch starts to complain so get an uprated clutch. The best mods we would do for your Premio are Remapping or piggy back ecu, fast road cam and air intake and exhaust.

Turbo engines are just crying out to be Reprogrammed. You will see impressive power gains on most modern turbo engined cars including diesels making a remap one of the most cost effective and impressive modifications for your money.The most phenomenal power gains for NASP engines usually involve the addition of forced induction. It is generally simpler to add a supercharger than it is to bolt on a turbo. It is harder to map a turbo as the boost builds exponentially with revs.

It is more straightforward to map a supercharger because the boost is directly proportional to engine speed on a linear curve. Adding forced induction will often require a lower compression ratio or water injection.

Alloy wheel upgrades.

Because alloys are lighter they improve performance and they help to cool the brake disks. Don't forget that your choice of rubber greatly affects your cars grip and handling. It is not worth compromising performance with cheap tyres when you can buy soft compound performance tires.

Large Allion/Premio alloys can decrease performance. If you get big alloys you will be changing your final drive ratio.

Due to this fact we would advise sticking to a maximum wheel size of 18 inches, although we know some of our members have with bigger wheels with no problems.
