hi, i am looking at modifying my altezza beams engine to approx 500whp turbocharged. i am concerned about the gearbox strength. i have read that they are storng but cannot get a good avg of about how much they can take until they give out......does anyone have experiences or know about this matter?
any help would be appreciated....thanks

Sorry but this is a US forum so everyone here has 6 Cyl 2JZ Engines. Good luck

I have no experience with the beams transmission but your best bet is to have an adapter made so you can use an r154 or v160 transmission
Hope that helps
