Boxes are different. Torque converters are different sizes. Have a look at the Hybrid Auto Gearbox Group DavidP has set up in the communities menu.

I was trying something out in the UK as the import and delivery of tc are rediculous it's about the same price as the tc it's self iirc a tc was 550 then 350 import and delivery.

The modifications only raised the flash point about 600 rpm so not really worth it . I think a 3200 stall would be the best bet for a street single .

Did you check the fluid level? Best bet would be to get the box rebuilt and uprated, I saw a link on here to a UK guy that was very good and did one for about £800.. WIll try and find it if you need it.

Wouldn't mind that link.
