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.
