I dynoed my motor and made 194whp and 138ft/tq
The motor:
B1a62
B18c1 bore 81.50mm
Blox b cams
supertech valve spring and retainers.
11.5:1 Je pistons
Full 2.5 cat back
JDM 4-1 ITR header
Blox intake manifold
64mm bore throttle body.

I will be buying a new header in a couple of day.
I will be buying the RAGE header for $650
I replaced my cold air intake for a J'racing intake.
I was thinking abuout using a bigger throttle body.
you thinks a 68mm will be enough or should i stay with the 64mm.
if i get a bigger throttle body, do i need to open a bigger hole on the intake manifold in the area where you mount the throttle body.
After this upgrades i will be hitting the dyno once again.
Im hopping to get 200+ to the wheels and better mid-range power.

 

Do you have a port and polish or a vavle job done to the head or any headwork?
