okay lets see i have a 2k si and i have the jrsc with the 6 psi pulley i also have aem cai jg edelbrock 4-2-1 two piece header 5zigen cat back. i also have the jackson fuel pump fuel pressure reg. and the 160 degree thermostat.with some watter wetter . okay i plan on getting the hondata ecu with the rc 440 rc inj.now what i want to do is run at least 8 psi or maybe even 11 psi. question do i have to upgrade my valve components , pistons and crank to be able to run the 11 psi . or is it all a matter of cooling and proper fuel management .and maybe all i need is the watter injection kit.ive heard soem bad stories on high jrsc boost with stock internals but maybe they didnt have enough cooling going on so i need to know whats up. help my *** please

 

You shouldn't need to upgrade any internals, buy you definitely need the water injection and good fuel management along with the injectors and so on.. Some people say you need to run high octane fuel, but I am not 100% sure about this part of it.

 

i ran 12 psi for everrrrrrrrrrrrrrrrr.
no intercooler, no water injection.............
you just need to make sure you dont run lean, ==== good fuel pump, good injectors (rc 310's), Cartech 20005 fpr, VAFC, J&S safeguard.
thats it.
you'll run 12.4's all day with slicks..........................

 

if your running 12's why dont you let me know what your whole set up is id love to have it .

 

My old 93 hatch had a B18C1 with a JRSC at 12psi. The setup was pretty simple. I ran a CRV pulley, MSD 6A, RC 310s, 2.5in exhaust, and testpipe. I never ran it at the track, but I am sure it would have pulled mid 12s all day long. The car pulled like a raped ape on the interstate. It was a huggggge difference going from the normal 6psi.

 

ive heard the crv pulley would only be 10psi but i am not sure did u have a boost gauge

 

stock internals?

 

Yeah it read 12 psi on the boost gauge. My bottom end was a basic build up. Arias pistons 9:8:1 with Eagle rods., and a STR blockguard. <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by redsidriver &raquo;</TD></TR><TR><TD CLASS="quote">ive heard the crv pulley would only be 10psi but i am not sure did u have a boost gauge

I don't know if the Si and GSR have the same supercharger. You may want to ask around.

 

Si, GSR, Type R all run the m62 blower.
