its an old school low comp setup using old school injection.
The yb is all about nothing nothing nothing then bam power.
depending on how much power you want will determine the drivability and torque characteristics with regards to low rpm.
Not so if mapped properly!!!cam choice is essential also...
As long as the cr isnt too low then a gt30 will work very well with the right inlet cam and mapping with near zero lag...
