Another gearbox question


dangerous brain

Recommended Posts

Looks like I am in the market for a new gearbox. Mine has started mucking around a bit and is limiting the power output of my car to around 500 horses when it could push 600 horses with a box that could take that.

So options as I understand it are

 

replace with another stock auto box

replace with an N/A 5 speed box

 

These options are cheap but will keep the power limited to 400-500bhp

 

Replace with a getrag 6 speed

Replace with a BL auto box

 

Both these options are extremely expensive considering the cars value and I am not sure if the BL box will last with the AEM ecu.

 

How much is a BL box these days anyways and where would I get one from.

 

Are there any other options?

?

 

Spoke to the guys at QSD while getting my conversation done, about what people said the 5 speed box can only take 500bhp, but they said they had a customer running over 600bhp, but i would image a vast clutch upgrade is needed lol

 

6-spped mate is the best option.. i'm afraid
