best place to get a v6 done

If you feel that way superart then turbo is the way to go.
The TTE turbo kit was the only Toyota approved significant power enhancement for the roadster.

Just because Toyota didn't do it doesn't mean we shouldn't.
The car was produced to a price and to meet certain market demands.
A V6 would have changed it's market sector and price point.
Who knows what was marketing department decisions and what the engineers thought the car was capable of.

The 2GR adds 60 kgs over standard. So ideally need height adjustable suspension. Coilovers.
A V6 conversion requires an access panel under the soft top to get to the other side of the V. Bit more noisy in the cabin and soft top may not always pack down flush.  More power needs heavier clutch. Takes away the standard ease of driving...

I can offer my experience with USPSPro's 2GR swap...

Thanks for sharing. Would love some photos of your access hatch/panel, exhaust system, clutch booster. Have you got a project page yet?

*Here*is USPSPro's build thread from 2010.
*Here* is a picture of the access door I cut.  Only peeled the ragtop away for access cutting the hole.  To use the access panel I just have to remove the package tray and fitted carpet piece.  *Here* is the access - plugs and coils.

*Here*is the pneumatic clutch booster.  Neat little unit, just like a brake booster but no pushrod.  It installs in the hydraulic line anywhere.  I stuck it on the rear crossmember  *here*

*Here*  are the only pictures I have of the exhaust system.  Bumper-off picture shows the aft cat, and if you look closely you can see the notch in the rear crossmember to accommodate the aft manifold.  The muffler *here*is pretty standard single inlet - dual outlet mounted by one V-band clamp.   Exh Tips picture

Toyota did do a V6 Roadster as a design study. Looked brilliant. No problem with the balance and feel of a V6 powered Roadster, its definitely the best incarnation I have experienced in 10 years of owning and driving them.

Would the best way of doing a V6 conversion be to buy a very cheap car with a knackered engine and then fit new brakes, suspension etc during the conversion?
Any other things that would need changing?

Seems to me it would be better than taking out and selling the engine from a lower mileage/working car (plus would help to keep more two's on the road).

My 2GR has original 1zz radiator and brakes, everything is stock except coil over suspension (and bigger wider wheels).  I even have AC and factory cruise control.    I'd expect a cheap car with blown engine to also have neglected shocks, tires, etc etc.
