Toyota MR2 Mk1 3vz-fe and 1mz-fe V6 Conversions

MK1 MR2 with 3VZ-FE - 3 litre, 24 valve, V6

Another Q&A detailing all you need to know about this superb engine conversion. Imagine combining the refinement and torque of a V6 Camry with the sharp handling, lightweight shell of the Mk1, what you end up with is a little monster of an MR2.

 

What Do I Get With A Conversion?

Every conversion includes a top end rebuilt 3VZ-FE, a Mk2 NA or Turbo gearbox, drive shafts, fuel pump, engine mounts and every component needed to make the swap a reality, all supplied by us. The engine gets new head gaskets, a re shimmed valve train, new cam-belt, oil filter, gear oil and a new clutch kit.

Every engine then gets fully detailed and painted in whatever colour scheme you want. This includes a complete respray of the engine bay as well.

We can also fit the TRD supercharger unit, but these need to be sourced from the US by the customer.

One of our 1MZ-FE v6 engines with TRD supercharger unit fitted.

All 3VZ-FE supercharged versions come with a Woodsport ISCV adapter body that ensures the stock idle control valve can still be used.No other Mr2 garage in the world fits the TRD charger to the 3VZ-FE V6, so you really do get something special.

How Much Does It Cost?

Typically we can build a Mk1 3VZ-FE V6 for around £3.500 all in, this rises to £4000 for the 1MZ-FE version and to add the supercharger to the 1MZ-FE option is free in terms of labour,to add the supercharger to the 3VZ-FE however is around £500 extra in parts and labour as it was never designed for that engine,but we can make it fit! Of course you need to add the cost of the SC itself.Usually these can be bought for under £1500 shipped from the US.

Is The Handling Affected By The Extra Weight Of The V6?

With the 3VZ-FE engine yes it is, but not as much as you'd think, in fact the difference is that it feels a lot more planted than before but we advise the upgrading of the suspension and brakes with every conversion, usually fitting koni adjustable shock absorbers and Gt4 brakes is all you need to keep the handling in check.

With the 1MZ-FE engine the handling remains practically unchanged,as it is a much lighter unit.

How Long Does A Conversion Take?

Around 4 weeks from start to finish, its probably the most involved mr2 engine conversion there is, its very labour intensive and everything needs modifying to make it fit, but a 4 week turnaround is the norm.

Will Everything Work As Before?

Everything will work exactly as before except the tacho will need recalibrating by a specialist company that we know of so that it reads the 6 cylinder signal properly, this costs around £50 and can be arranged by us.

We will have to modify the boot wall to accept the bigger engine and part of this means you get a nice access panel to the rear bank of spark plugs, something the Mk2 boys dont get with their conversions.Also the engine lid will need modifying, you will lose the engine lid catch so we will have to place the engine lid on bonnet pins or similar.

What Major Modifications Are Involved?

We need to completely remove the old engine mounts from the chassis, and then weld in new engine mounting brackets to support the weight of the new engine.

Here is a freshly prepared engine bay, all new mounts welded in,spark plug access panel at the rear (optional) and the engine bay resprayed.

 Williams review....

 

On the train up to Durham I, in reality, I had some idea what to expect. As a previous customer of Woodsport for a 3vz-fe conversion, a 2gr-fe conversion would be similar, right? But how wrong could I have been!  

The results of Pauls work an hour later when at Woodsport were simply stunning! The car was pristine, the engine and the engine bay were immaculate and it was hard to believe it was the same car I had dropped off a few weeks earlier.   

Turn the key in the ignition of a 3.5 litre MR2 and from the moment it fires up there are only two things that are guaranteed. The first is you know just from the sound, that it is going to be a powerful car. The second is that, every time you drive it, you will have a smile on your face! The only thing putting a downer on that moment was knowing I had a 270 mile trip back to London when I couldn’t explore the full potential of growling V6 behind my ear.

Having filled her up with premium gasoline (defiantly recommended!) I joined the A1 ready to settle into the running in stage.  At a cruising speed of 65mph she ate up the miles effortlessly, refined and relatively quiet, a general nice place to be. 

Then you go for an overtake.  MY GOD! Drop to 4th gear and bury  that right hand pedal and the noise! The torque! The acceleration!…. One word…  Beautiful! In the words of Jeremy Clarkson, ‘you turn the big thing in the middle to make it turn, you push the middle pedal to slow it down and you push the right hand pedal to make more noise! And what a noise!   

… Well that was a few months ago now and I’m pleased to say she still puts a smile on my face every time I drive her. If anything, an even bigger one as she’s now fully run in and I can now unleash her full potential. Where better to do this than at Brands Hatch. To see the look on the face of a 944 driver in his dedicated track car as he gets lapped by a 20 year old Toyota. To be able to out drag XXR’s and M3’s. This engine is a brute! And I absolutely  love it!     

Last but not least to sum up Paul…

I truly believe there are three types of people in the world:

  1. The type that when a challenge is thrown at them just walk away.

  2. The type that will take on a challenge and fail hopelessly on so many occasions they just end up giving up, but hay they had a go… (this is me!)

  3. And then there’s Paul. A person who seems to conquer any challenge thrown at him and just for good measure, makes it a little better.

Paul, you’re a legend. Big thanks for all your hard work and I will no doubt be seeing you shortly for a supercharger as I have officially now managed to ‘Tame the Beast’! 

All the best, and keep up the good work!
