Which is better for some drag racing? My car will be driven quite often on the streets with some passes at the drags, but probably will never do any autocross.

My car will be making about 600 rwhp and 600 rwtq.

I have talked with most of the rx7 shops and some recommend the cusco as they claim its stronger than the kaaz, but some shops say the kaaz is best for drag racing.

What do you guys think?

 

FWIW...According to Rx7.com, they use the Kaaz units for all their race cars.

That is what the told me as well, but others have claime that cusco is much stronger than than the kaaz.

Any other thoughts?

 

Considering their racing backround, I'd take their advice.
