I have a 93 si and was getting ready to install jrsc. What all needs to be upgraded for safe install at 6 psi. The motor was just rebuilt new bearings, rings,seals,and belts. Also as anyone used the new jrs maping sys. they have out ?

 

upgrade the fuel pump and get the MAP convertor. you will be good to go. The MAP convertor is the **** and it might be included in the kits soon.

 

what fuel pump would you go with, and an in tank or piggy back set up.

 

Id go with the In-tank.. It might not be a bad Idea to run a FPR and get some gauges to help you tune it so you dont blow your motor... Remember... Good tuning is your best defence against detenation..

 

High Pressure Fuel Pump (intank)
Fuel Gauge and boost gauge
FPR
J&S (optional but recommended)
a/f meter

That should be it for 6 psi.
If you have more questions drop me a line.

 

what about timing stock or retard and what type plugs? Also would you drop to a 160 thermostate?
