hamza check it out:

the toyota 3GR engine family have a few superchargers that coule work for us if we can infact modify supercharges

TRD USA made one for the FJ Cruiser (1GR-FE engine 4.0l v6). Its a modified roots type Eaton E90 supercharger. FJ's have a compression ration of 10.0: 1 and make around 65hp (27% increase) and 68 more lbs/ft (25% increse) but thats including effects of intercooler and remapped ECU.


TRD Austrailia made one for the Aurion(2GR-FE engine, 3.5l v6) , they use the Eaton TVS supercharger. Aurion has a compression ratio of 10.8:1. This one makes around 50hp increase (18.5%) and a similar figure for torque.


Toyota Japan made a special edition supercharged Mark X (3GR_FSE engine called the 3GR-FXE because of the supercharger). MArk X has a compression ratio of 11.5:1They say its a TOMS supercharger, but i think TOMS uses modified roots type Eaton supercharger. Not sure of the power numbers. This engine is a 3.0l v6 same as ours but theirs has both port and direct injection.

Toms makes a supercharger for the is350 (useless for anyone not living in japan) and hopefully will make one for our IS300. But its unlikely.

Moral of this story? The second gen IS300 with a 3gr-fe engine and a compression of 10.5:1 can easily cope with a supercharger

Anyone know of anyone that has modified a supercharge to fit a different but similar engine than the one it was designed for?? can this be done? if we could modify either the aurions or the mark x's supercharger wed be in business
