aight i got a 91 integra...b18a1, T3, SMC, fuelpump...i need to know what i need to run 450cc injectors, do i need to modify anything to run these. i hear all this stuff about lowering the voltage to the injectors using resistors, but do i need that, do u think maybe the SMC will allow me to run them with no other mods

Yes you need to run resistors. Either the radio Shack (10 ohm) resistiors, or a resistor pack out of an older crx, civic, or integra. If you don't, you will damage the ecu.

"or a resistor pack out of an older crx, civic, or integra. "

out of what year, and what computer

TurboEF9

88-91 Si

TLshizz

a resistor pack out of a 88-91 si, is it inside the ecu? or is it outside just wired into the injector circuitand what does it look like

It should be mounted on the firewall. Do a search on ebay for resistor box for a picture.

yo i went on ebay....saw a picture of one that came out a 90-91 integra pr4..?thats what i have, do i still need a different one

88-91 Civic/Integra already have resistor boxes on the driver's shock tower. You should be set to plug and play with those injectors, bro.

FYI, the last resistor box I checked came out 6.4 ohms, not 10. HTH... and TLshizz, you got your lol.

good ---- thanx a lot!!!

i thought a 91 integra had a resister box on it..?? somebody correct me if I am wrong..
