what are the pros and cons of doing the throttle body mod on my 87 na.


Thanks

Pros - slightly better air flow, a little extra hp, better throttle
response, coolant no longer flows through the TB, no
thermowax to go bad

Cons - lack of thermowax affects the cold startup. Your car may
not idle properly until your car is warmed up. This does
not always happen, and it didnt happen to me, but it can.
