i just finished up installing that 4k tci converter and damnnnnnn what a difference, my restalled stock converter was so inefficiant.
i pulled the turbo to drive the car around the shop to see how well it would perform na,and its an awsome converter,the car actually jumps outa the hole like a v8,
then i put the turbo back on and holy ****,i could get 9-10 psi footbraking the car before the tires would start to spin.and as soon as i let off the footbrake to launch i had instant full 12 psi.couldnt even keep the car straight.
either way na/turbo this converter is dam well worth the investment if ur gonna do any kind of performance work

 

The link in the aftermarket parts thread doesn't work.

 

it works for me

 

I like hearing stuff like that. Soon as the top end is done and turbo is in, I'll be working on the rest of the drivetrain...
