Is there a home build conversion kit for the 3.0 V6 for my rev2 N/A?

Not sure if there is a kit, but paul woods of woodsport and a few members on two brutal have the jug it you want to cut out your old engine mounts and weld in new ones. I did find someone selling a mount conversion kit.

Very easily doable at home. Me and the bro in law managed it though the engine he bought came with the engine mounts already and was sort of a loom already modded so wasnt hard at all.

I see the engine mount on Paul's site for £85.

What needs done to the existing loom or do you need a different loom?

How hard/easy is the 2GR-FE to swap in?

They're easy enough to do if you're mechanically & electrically minded.

Have a look here for what's needed for a 3VZ swap..

The 2GR - it's not really any 'harder' per se .. It's just everything is +++ on the pocket. Where a 3VZ can be done for around £5-600.. I will doubt my 2GR will be under £4k...

I see 2gr-fe engines for sale in the states for $2000.

Can the 3.0 V6 see near 300bhp?

the 3vz or 1mz will see 210bhp plus (with ypipe and a bit of porting)
but its the torque more than outright bhp for these engines. you would be looking at 220ftlbs plus.

with a standalone ECU 225+bhp/ 225+ftlbs is achievable

supercharge it you would be looking at 260+ bhp and 240ftlbs +


turbo it and 300 bhp is possible

supercharge and turbo costs on top will take you into 2GR territory so IMHO not worth doing, 2GR is then the way to go.

Thanks buddy, what's the best 3.0 V6 for supercharging at a later date?

3VZ as it is iron block, although seen a few 1MZ's with good power as a supercharged unit.

Its a pick and mix one really, either will work but the 3VZ is stronger

It's possible for all of those v6 take boost but it's not cheap at all. Would suggest having a go or a passenger ride in someone's car to see if they float your boat in na form

I was very surprised at the power of the 3vz we done. It kept up easily with my rev 2 turbo.

2GR gives more than enough power in n/a form. It has freight train torque from idle, and at any point through the rev range.

Putting any forced induction on those is just for bragging rights imho, and would just be too much power for the car - some people will probably shoot me down in flames for saying that but its my opinion - 2GR itself is a monster in an mr2.

Paul from woodsport got back to me and he does all the necessary bits and pieces for the 3.0 V6.

He reccomends a the Lexus RX300 1mz-fe, 99-2002 model.

This seems the easiest him build option but I don't want to do this and then feel like the car needs 2gr power.

It all depends on how deep your pockets are and how much hair you wish to be pulling out...

Stock 1mz will be around 200hp and a fairly pain-free conversion. It'll be quick to do and plenty quick enough to drive.

1mz SC will sting the pocket. The bolt-on SC's from TRD are becoming like hen's teeth to find as they all seem to find their way into enthusiasts hands - then command £1500 at a minimum.

So you could do a Rotrex SC - that's around £1800 to start with - plus fitting piping and cooling of some sort. Plus you'll want Turbo running gear.

Or Turbo 1mz - that again for a low blow, well cooled could see ~300.. Though if going turbo I would suggest a 3vz as they're stronger. There's one in Germany on a stock engine with fibre gaskets pushing out 390whp. (Decent Turbo, proper fuelling and excellent cooling - stand alone ECU).. But you're talking £10k easily.

2GR ...
As the voice of experience.. This is not a cheap or easy power route.
Like you say - engines on ebay USA - $2000. Then it'll be around £1250-1500 to get it to the UK (including import duties)... Not forgetting you'll need an assurance it's a good runner and they'll supply all parts you need.
I can fabricate the engine mounts for the drivers side for around £120.
You'll need manifolds (I have a UK solution for £600 which I am waiting to see the results of or Gouky's for around £800 once imported.
Then a custom y-pipe £3-400
Then custom exhaust £3-400 at least
Installation... If you can do the mechanicals yourself I think you'll need someone to wire it up - 2 days labour I reckon.
I'm assuming you're N/A at the moment..? So you'll need a turbo gearbox (with LSD), driveshafts, hubs etc - £1000
Factor in another £500 for odds and ends (oils, coolants etc).
It soon adds up.... To hair loss I assure you! :laughing

Honestly ... what do you want...?

Do you want a little more grunt than N/A but torque from low down?
- Buy a for conversion 1mz as Paul suggested

Have you had turbo cars previously and love the surge of power?
- Buy an MR2 turbo or convert yours to turbo (buy a whole car - cheaper)

Do you want something unique with a cracking sound to it and plenty of poke?
- Do a 1mz SC conversion

Do you want that slab of power from standstill & cannot stand turbo lag?
- It'll be the 2GR conversion for you then sir!

It's definitely a 'horses for courses' or 'strokes for folks' scenario. Plus not just a case of wanting more power. We all (well most) want more power but how it is delivered is more important. :th:
