upgrade Primary or Secondary injectors??
The setup on my new engine will be as followed: all bolt-ons with a big street port, Power FC, and walbro high flow. Should I go with bigger primaries or just upgrade my secondaries. I will be tuning for 12 psi. max boost. on stock twins. BTW, I have done a search, but would like some more opinions on this. Thank you

Hi Ted,
yeah, at only 12 psi you'll be ok w/12 or 1300 secondaries and stock prim's. Here are some good links to find out if your injectors and punk will support your horsepower goals:

Now that I have a PFC, and some extra 850cc injectors, plus a tuning day setup with Steve Kan, should I install 850cc injectors in my primary, or just skip it, and go to 1300cc in my secondaries ?
I'm thinking about 12-13psi of boost on the stock twins max.
This is for a daily car, that I use on track days and on autox.

Here's my current setup:
NEW engine with 5K miles on it
ARC SMIC
'99 SPEC intake duct with STOCK airbox
Supra TT fuel-pump
Efini Y-Pipe
JDM downpipe (no pre-cat)
High-flow metallic cat w/air-tube
Magnaflow resonator
TRUST muffler
PFC with RX7Store base tune for above (injectors at 80% duty-cycle at WOT)
currently idle surges when below 40-F, otherwise fine
