Engine/Transmission (1998.5 - 2002) Eth Hp Gain

[Silver]

What HP, TQ increase can I expect when I add DDIIs to my ETH? How about DDIIIs? I already have an EZ so I'm looking for gains on top of what the EZ already gives me . Thanks guys.

Real close to 90 for the 2's and 115 for the 3's.

expect about 345 HP with an EZ and DD3's... and a wasted stock clutch!

Not exactly what you asked for...but

I put down 268rwhp with the 275's (along with whats in my sig). With the 275's and the EZ I put down 310rwhp.
